(i.e., 56/64 Kbps RS449, fiber optics or 64 Kbps G.703). The PDR-2000 can also be used over a voice grade audio channel when equipped with an Audio Communications module. Up to eight Trip commands can be inputted to the unit and up to sixteen Trip outputs may be provided from a terminal.
Page 6 SPEED: The PDR-2000 is a high speed communications terminal. Trip times average approximately 3 ms for digital interfaces and 14 ms for the audio interface. Due to the size of the PDR-2000 communication packets and the delays inherent to multiplexed digital communications, times vary, see Section 2, Digital Communications, for more information on packets.
Page 7 Com port, or a Ping test failure that can indicate excessive propagation delay. TRIP IN MODULE: Up to eight trips can be input into the PDR-2000, these are handled by the Trip In module. This module contains optical isolators and communicates detected trips with the uP module.
Page 9 SOFTWARE: There are two types of software that relate to the PDR-2000. The GUI is run on a PC and does not directly affect the operational parameters. The GUI is used to change settings, review the status of a unit, view events, and download firmware.
Page 10 The GUI version number is PDR2000 GUI 1.1. The number at the end (1.1) is the version number. The version number is part of the name of the GUI that is located on the Desktop or in the INIVEN folder as part of the Start menu.
Page 11: Digital Communications
The Com port module is a physical interface that allows for different types of connectors to be used with the PDR-2000. Two screws attach this module to the rear of the chassis. It mates to a connector located on the Interface board, see Section 16, Chassis for more information. The Com Port module comes with two complete interfaces of whichever type is supplied with the unit.
Page 12 The PDR-2000 is capable, as listed previously, of communicating more then just Trip and Guard inputs. By using the PDR-2000 GUI (Graphical User Interface), a local unit can be used to get the status, get the settings, get the events, send new settings, and send an erase events command to a remote unit.
Page 13 PC or to erase events in the Flash memory. These packets can be forwarded along the Com link connecting units until the PDR-2000 addressed by the GUI is reached.
Page 14 TYPE D AND E Type D packets are used for a unit to send responses to the PC in reply for a request for information. Uploading settings, status and events are three types of information sent. Type D packets are also used to download settings and firmware to the unit from the PC.
Page 15 Guard) commands. The PDR-2000 does not use the Unit ID number to address to a particular unit. It is used as an address from a unit. The receive logic determines if the Unit ID number as well as the Trip/Guard data contained in the received packet have the requirements to output a Trip.
Page 16 PACKET FORWARDING Packet Forwarding is used by the Trip commands and the GUI communications. When the unit is programmed with the Packet Forwarding feature turned On, all Type A packets are retransmitted. When a packet is retransmitted, it is received on one Com port and transmitted on the other port. Packets are not forwarded on the same Com port they are received on.
Page 17 140 Hz each. Twenty of the sub-channels carry digital data, two of the sub-channels are pilot channels that synchronize both ends of the PDR-2000 communication channel. Of the 20 data sub-channels, each sub-channel transmits 2 bits for a total of 40 bits. The 40 data bits are made up of...
Page 18 PDR-2000. The purpose of this communication is for programming and retrieving information. HARDWARE The PDR-2000 comes with two RS-232 ports. A 9 pin DCE port is located in the front of the chassis and a 9 pin DTE port is located on the rear of the chassis.
Page 19: On-Board Programming
Section 3 ON-BOARD PROGRAMMING This section describes all the processes available to program the PDR-2000 without the use of any external equipment (see Section 5, Installation for step by step installation instructions). There are up to four ways to program the unit; the Display module on the front panel, a PC using the RS-232 port on the front panel, a computer using a RS-232 port (or other communication port depending on unit configuration) on the rear terminal block board, or a computer connected to another PDR-2000.
Page 20 PROGRAMMING To program the PDR-2000 press the F1 key to enter the SETUP menu. The next screen will ask you for the unit’s four digit password. You must enter the correct password before any settings can be changed.
Page 21 There are three options in the general programming menu. S E T U P S E T U P S Y S T E M S E T U P Figure 3-4. General Programming Menu RX SETUP contains all the logic settings for receive channels and Trip outputs. TX SETUP is used to program a transmit logic for the transmit channels.
Page 22 Figure 3-7. System Setup Menu C UNIT IDENTITY is used to program the PDR-2000 Unit ID and to turn the Unit ID feature on/off. Unit ID increases security by requiring receiving units to be programmed to receive Trips on a particular channel and only from a unit with the proper ID number.
Page 23 DATE/TIME SET is the manual internal clock setup for the sequence of events recorder. This is used to enter the year when first powering on the unit when an IRIG-B input is used. When an IRIG-B input is not used, this is used to set the internal clock for time and date. ALARM SETUP is used to set the programmable status relays and change the default time delays on the Alarm, Block, LOC1, and LOC2 Relays.
Page 24 The Unit ID Activation menu turns this feature on/off. The PDR-2000 transmits its Unit ID number in each string, this can not be turned off. When Unit ID is Off, a PDR-2000 only requires that another PDR-2000 sends an appropriate signal for the outputs to operate and ignores the Unit ID number in the receive logic.
Page 25 If the Unit ID feature is not being used, it is still important that a unique Unit ID number be assigned to the unit for use with the GUI, see Section 4, Remote Programming. NOTE: It is recommended that every PDR-2000 being used in the same communications system whether they are interacting directly or indirectly be assigned different numbers when possible.
Page 26 2. PASSWORD: The default password for the PDR-2000 is 1234. It is recommended that the password be changed to limit access to the vital parts of the software. All features that do not affect the operation of the unit are accessible without the need of the password.
Page 27 3. SEND TRIP MANUALLY: The PDR-2000 can transmit a Trip on any or all channels manually, without the need of a Trip input. E N T E R P A S S W O R D _ _ _ _ C L R Figure 3-13.
Page 28 M A N U A L O U T 4 + 5 A R E Y O U S U R E ? Y E S Figure 3-16. Manual Trip Final Confirmation Menu The final menu confirms that the Trip(s) are to be sent. This is the last menu, pressing F1 will commence the Trip(s).
Page 29 NOTE: Do not use Packet Forwarding when the Audio Communications module is installed. Packet Forwarding works in conjunction with Unit ID and the two standard Com ports (see COM SETTINGS later in this section) to pass on Trip/Guard commands to other PDR-2000’s that are not directly connected.
Page 30 Programming the PDR-2000 with Packet Forwarding On is the same as with only Unit ID On but more care needs to be taken when programming the Receive Logic of units on a larger scale network to avoid incorrect Trip outputs.
Page 31 5. DATE / TIME STAMP: There are two ways to enter the date and time for the sequence of events recorder. An IRIG-B modulated input connected to the BNC connector on the rear of the chassis will automatically update the event timing. If this is not available, the time and date may be entered manually.
Page 32 6. ALARM SETUP: These menus are used to program status alarms and optional Trip cut out switches. ALARMS: The PDR-2000 has ten Status relays: Alarm, Block, LOC 1, LOC 2, PROG 1, PROG 2, Unit ID Off, uP Fail, PWR 1 Fail, and PWR 2 Fail. The first four of these alarms are programmable for delay.
Page 33 Choose the Status relay using the keypad and press F1. S E T D E L A Y I M E s e c D O W N Figure 3-23. Alarm Delay Time Set Menu If one of the first four choices are made, the Alarm Delay Time menu appears. Set the delay in 1.0 second increments using the F2 and F3 keys.
Page 34 TRIP CUT OUT SWITCH: The PDR-2000 is available with an optional Cut Out Switch. There are two versions of this option that can be supplied. The Cut Out Switch (CC2256-00) is a module designed to occupy the two slots on the furthest right hand side of the chassis normally occupied by the optional dry contact relay trip modules.
Page 35 RS-422, the communications system may use the rising or falling edge of the clocking signal. The PDR-2000 defaults on the rising edge of the signal. If it is to be used with a system that uses the falling edge the PDR-2000 needs to invert the clock. The Audio Communications module uses falling edge timer and the Invert Clock setting must be turned on for the the unit to operate correctly.
Page 36 8. AUTO PING TEST: The Ping test performs a complete system test of the digital communications and the receive and transmit capabilities of the PDR-2000. The Ping test also shows the results of the round trip time required to perform the test and the communication delays involved.
Page 37 9. AUDIO SETUP: The Audio Communications Module requires additional settings not required by other communication modules. The output level of the transmitter must be set in accordance to the 4W audio line being used. The standard setting is -8dBm. This may be adjusted based on the quality of the line and local practice.
Page 38 RX SETUP Receive Setup: Receive logic parameters are made by programming the outputs. There are eight Trip outputs (1 through 8). These outputs can be programmed to correspond with any of the eight channels (A through H) or eight local Trip input (1 through 8) with or without the use of logic gates. To program an output, choose the output using F2 and F3 to move the cursor to the desired output number.
Page 39 1. TRIP RX LOGIC: This menu gives the user the ability to program the logic for each Trip output. NOTE: The default setting for the PDR-2000 is Unit ID off. In this case, unless otherwise programmed, Trip output 1 is set for Communication Channel A, Trip output 2 is set for Communication Channel B and so on.
Page 40 Repeat the above procedure to program the eight outputs. If Unit ID is On, the Unit ID of the transmitting (remote) PDR-2000 needs to be entered when the Communications Channel is added. If all inputs are set to Off the output relay is turned off.
Page 41 Unit ID’s are confirmed only on the receive side of the Communications Channel. If the unit is communicating with more than one other PDR-2000, either because both Com ports are in use, Packet Forwarding is being used, or both, more than one Unit ID may be used for the multiple receive channels.
Page 42 2. PRETRIP TIMER: This menu is used to increase the security by holding a received Trip for the programmed period of time before the Trip output is activated. P R E T R I M E R 5 m s e c D O W N Figure 3-40.
Page 43 3. GUARD BEFORE TRIP: This menu programs the Trip output to require a Guard to be present for a period of time before a Trip will be allowed to be output. G U A R D B E F O R E m s e c O F F D O W N...
Page 44 4 . TRIP RX HOLD: This menu sets the minimum amount of time a Trip will be output. EXAMPLE: If the Trip Rx Hold is set for 10 ms, any received Trip that lasts for less then 10 ms will be output for 10 ms Trips that last longer then the Trip Rx Hold time are unaffected by this setting.
Page 45 5 . LATCHING TIMER: This menu sets an added amount of time to a Trip output. EXAMPLE: If the Latching Timer is set for 100 ms, any received Trip will be extended for 100 ms after the Trip is no longer present. The Latching timer is added to the output after all other logic in the system.
Page 46 TX SETUP Transmit Setup: There are two timers that can be programmed as part of the transmit logic, Trip TX Hold and B Contact Keying. Transmit logic automatically ties Input 1 to Channel A, Input 2 to Channel B, and so on. To program a transmit channel press F2 and F3 to choose a channel and then press F1.
Page 47 1. TRIP TX HOLD: This menu is used to maintain the transmission of a Trip for a minimum period of time. If a Trip is input, the timer starts, and will maintain the Trip for the duration of the timer even if the trip input should drop out.
Page 48 2. B CONTACT KEYING: This menu is used to ensure a Trip does not last longer than the time programmed. Once the Trip time has expired the channel will transmit a Guard signal until the input has returned to Guard and then back to Trip at which point the entire process starts again.

A male/female nine pin cable is required to connect a standard PC’s nine pin serial port to the PDR-2000 (a null modem cable is not required). The male nine pin RS-232 located on the back of the chassis is a DTE port designed to be connected to a modem or other communication device.
Page 51 The PDR-2000 GUI will run on any standard Windows® operating system. It is recommended that the GUI be run on a computer with a screen resolution of at least 1024 x 768. All programming is performed on the System configuration tab at the top of the screen. There are six tabs at the bottom of the screen.
Page 52 The LED’s will light and the Display will match that of the real unit. The last two slots of the PDR-2000 are not shown on the virtual PDR since there are no indicators for those slots.
Page 53 To program the B Contact Keying timer, click on the On/Off box for the corresponding channel. A check mark should appear and the Off should change to On. Then click in the timer field to the right and enter the time. The time represents the maximum amount of Trip signal that will be transmitted. If the On/Off box is Off and a time is entered, the B Contact Keying logic will be ignored.
Page 54 The Pre-Trip timer adds security by lengthening the Trip time beyond the PDR-2000’s standard security settings. To program the Pre-Trip time, click the mouse on the Trip out to be changed type in the new value.
Page 55 5000 ms. Repeat for all the Trip Outs whose values needs to be changed. RX Logic: This menu gives the user the ability to program the logic for each Trip output. NOTE: It is important to understand that when programming the PDR-2000, the Trip Outputs, not the channels are being programmed.
Page 56 To program the Trip outs, choose the desired input from the pull down menu. Trips are designated CH A-T for channel A, CH B-T for channel B and so on. Guards are designated CH a-G for channel A, CH b-G for channel B and so on. If the input is to be inverted click on the arrow to the right of the input and a circle is added to the tip of the arrow to indicate the input is inverted.
Page 57 inputs 3 and 4’s gate output. The result of this gate is then gated with inputs 5 and 6’s gate output. All the gates are programmed in the same way. The end result of all this logic is the Trip output which then passes through the receive timer logic (described earlier in this section).
Page 58 Unit ID: This is the number of the PDR-2000 that is being programmed. Every time a packet is transmitted from a unit, the Unit ID number is included. The default number is 01. Each PDR-2000 that is on the same system should be assigned a unique number, whether the Unit ID feature is On or Off.
Page 59 This is not necessarily the local unit connected to the computer. The default password for the PDR-2000 is 1234. It is recommended that the password be changed to limit access to the Settings. To change the Password, enter the existing password in the Password field and the new Password in the New Password field and the Confirm New Password field.
Page 60 On. This allows the user to program the settings, get the status, get the existing settings, retrieve stored events, erase stored events, and generate a Ping test to any PDR-2000 communicating with the originating unit directly (Unit 1 to Unit 2 in the example) or indirectly (Unit 1 to Unit 3 in the example).
Page 61 Invert Clock: For RS-422/RS-449 synchronous communication applications and for all other applications where the PDR-2000 receives its timing signal from the communication device, not G.703 or C37.94. The standard setting for this clocking is on the rising edge of the signal. If this needs to be changed to the falling edge, set Invert Clock to the On position.
Page 62 The fifth tab in the UNIT SETTINGS field is Memo. This section is used to view and add notes to the nonvolatile memory of the PDR-2000 uP module. The Memo section may be used for maintenance logs, programming notes or anything else. Up to 4000 characters can be held in memory. Notes in the Memo section are treated as any other setting in the UNIT SETTINGS section.
Page 63 A Download Complete message will indicate the process is finished. It is necessary to turn the main power switch on the front of the PDR-2000 Off and On for the new Firmware to be installed. A message will appear on the display of the unit that the new firmware is loading. When the new firmware is finished loading the unit must be restarted again.
Page 64 Click on the Save button. Choose the Directory of the disk drive the file is to be saved on by clicking the down arrow next to the “Save in:” field. Next name the file. To save the file as an Iniven Unit settings file, the file name needs to end with the .ust.
Page 65 PRINT SETTINGS The settings in the GUI may be printed in a one page report. Settings from a disk or unit need to be uploaded to the GUI before they can be printed. To print the settings list, click on the Print button on the right side of the System configuration screen.
Page 66 Section 2, On Board Programming, for a description of the logic statement. MODEM SETTINGS The GUI may be used to connect a computer via a modem to the PDR-2000. The unit is designed to connect a modem to the rear RS-232 port. Once the modem connection is established, program the unit normally.
Page 67 TRIP/GUARD PACKET AND OUTPUT STATUS The sixth tab is inputs_com. This tab allows the user to see two things in the unit. The first is the current status of the 8 receive channels, A through H, from all 99 unit ID numbers. The second is to see the status of the 6 inputs for each of the Trip outputs.
Page 68 Output Logic Status: This section on the right of the screen is used to determine the 6 inputs’ status for each of the 8 Trip outputs. The 6 inputs are located on the RX Logic tab. In1 is the top most input, In2 is the input directly below and so on.

Page 70: Installation
This section of the manual covers installation, unpacking, mounting and interconnect wiring instructions. UNPACKING The PDR-2000 may be supplied as an individual chassis, stacked interconnected chassis, or mounted in a rack or cabinet. Follow the procedure for the type of system supplied.
Page 71 To reduce the possibility of induced currents on the Trip input leads, it is recommended that shielded twisted pair wires are used with the shield grounded at the PDR-2000 end only. The Trip input leads and the communication cables should be bundled separately from each other and the other leads. It is recommended that the mounting rack be grounded.
Page 72 The DTE RS-232 is located on the rear panel and the pin locations are shown in Figure 5-1. Make sure the cable’s connector is properly seated and screwed down tightly. The IRIG-B connector is a male BNC. The internal clock will accept standard modulated IRIG-B signals. Figure 5-1.
Page 73 PROGRAMMING The PDR-2000 can be programmed using a PC or the front keypad and display. It is important to remember that the Trip logic is assigned to the Trip out circuits and not the channels. A single channel may be used by several different Trip out circuits with the same or different logic schemes.
Page 74 Using the GUI This is a step by step instruction for using the GUI to program a PDR-2000. For details on using the GUI and the function of the different operations, see Section 4 Remote Programming. 1. If not already On, turn the Main Power switch On.

Page 96: Event Recording
Section 7 EVENT RECORDING The PDR-2000 has an Event Recorder built in to the uP module. The Event Recorder time stamps all activity that takes place in the unit. Events include all Trip and Guard inputs and outputs, status relay activation, password access, and initial power on.
Page 97 All events with a duration are recorded with their start and stop time. Events are stored in Flash and will not be erased if power is lost or the clock’s battery dies. The Flash will store approximately 40,000 events before it starts rewriting over existing events. EVENTS WRITTEN ONCE The following are one time events and are written once as the activity occurs and there is no follow up event to indicate the situation has changed from On to Off :...
Page 98 Bit Error Channel 1 12 with the last number being the percentage of bad packets received in the last 1000. The time recorded with the event is from the last of the 1000 packets. The PDR-2000 will not start counting again until at least 1 bad packet due to bit error is received.
Page 99 DELAYED EVENTS Four of the Status alarms may be programmed for the delay of the output relay. Two of those alarms, Alarm and Block, also delay their being logged in the Event Recorder. The same delays programmed for these alarms are used for both the dry contact and the Event Recorder. The advantage of the delay is to avoid excessive amounts of events being written due to bit errors.
Page 100 DCE port. A male/female nine pin cable is required to connect a standard PC’s nine pin serial port to the PDR-2000 (a null modem cable is not required). The nine pin RS-232 located on the back of the chassis is a DTE port designed to be connected to a modem or other communication device.
Page 101 NOTE: Packet Forwarding does not need to be On for the GUI to upload events or erase Flash from a PDR-2000 indirectly. That type of Packet Forwarding is always On. Therefore, it is always important to confirm the Unit ID before communicating with a unit.
Page 102 MANUALLY ENTERED TIME The keypad and display of the PDR-2000 allows for the time to be entered manually. It is also the only way for the unit to receive the proper year input. To enter the time manually, follow the sequence below.

Section 13 STATUS RELAY MODULE Figure 13-1. Controls and Indicators, Status Relay Module i t c l i a l i a t i n t i n Table 13-1. Controls and Indicators Description, Status Relay Module DESCRIPTION The Status Relay module contains eight relays (Alarm, Block, 2 Loss of Communications, 2 programmable, Microprocessor Fail, and Unit ID Off) and eight relay driver circuits.
Page 151 RELAYS ALARM: This relay is a general alarm. If any condition exists that would activate the other Status relays (other then the Unit ID Off alarm, Power Fail, or the Programmable alarms), the Alarm relay is energized. The Alarm relay is programmable for delay in 1.0 second intervals, see Section 5, Installation for programming details.
Page 152 Trip Out: If any of the Trip output circuits are activated, the relay is activated. MICROPROCESSOR FAIL (uP Fail): When a PDR-2000 is equipped with two uP modules, the uP Fail alarm indicates when one of the modules has stopped functioning. If the unit is only equipped with one uP module and it fails, all the relays will drop out.

Page 172: Option Modules
Section 17 OPTION MODULES This section contains instruction inserts for any option modules that are included with the PDR-2000 that accompanied this manual. Option modules may change the operation of the unit. It is important to read this section to determine the affects of the options.
Page 173 DESCRIPTION The Universal Relay Module is an option for the PDR-2000. Each module contains four dry contact relays that can be used for Trip outputs. Each relay is a form C relay that can be used as a form A or form B relay depending on jumper position.
Page 174 Note: The following description refers to Relay 1 (RL1) and is applicable to all four relays if equipped. The station battery or the voltage controlling the relay coil is connected to J1-1A and J1-1C. The negative side is connected to one side of each of the relay coils. The solid state output of the Multi- Trip module connects the positive voltage from J1-4C to J1-4A and to the other side of the relay coil via C1 and R1.

ISSUE: The GUI has locked up and does not respond to user input. POSSIBLE CAUSES: 1. The cable is not connected from the PC to the PDR-2000. 2. The wrong Unit ID number was entered when downloading settings or firmware.
Page 184 DISPLAY ISSUE: A setting has been changed but the unit does not seem to accept it. POSSIBLE CAUSE: The F1 (or OK) button was not pressed when the change was made. SOLUTION: Go back to same menu and confirm that the setting change has been made. If the setting is still in it’s original state, make the change again and press the F1 button for OK.
Page 185 ISSUE: The unit logs a bit error event when I am requesting information from a remote unit. POSSIBLE CAUSE: The Ping Test is active and the communications priority gives Ping Tests a higher value then data transfer (but not Trip/Guard packets). This may cause a data packet to be cut off in order to accelerate the Ping Test packet.
