0° C to 60° C for a period of 24 hours. A computer record is maintained for every analog I/O module. Throughput: System response or throughput for the I/O PLEXER can be calculated using appendix B. I/O Signal Compatibility I/O PLEXERs use duTec I/O modules to match signal requirements exactly.
Page 9: Easy Setup
Based on the reported status, the Host makes control decisions and transmits this data, as instruction messages, to the I/O PLEXER which uses the new decisions to make the proper changes to its various actuators. Both the Host and the communications link are essential elements in this data acquisition and process control scheme.
Page 10: Available I/O Functionality
Introduction 1 Available I/O Functionality: Analog Inputs Input Value Determines signal levels, with 12 bits resolution* Offsets Input values can be software offset, with 12 bits resolution, over the module’s specified range. Gain/ Slope The amplitude of input values can be software multiplied by factors ranging from 0.25 to 4.0.
Page 11: Digital Inputs
Introduction 1 Digital Inputs Read Read the ON or OFF state of all inputs. Pulse widths The duration of a single pulse or total on/ off time of consecutive pulses can be resolved to the nearest 0.01 seconds for a max total of 10.9 min, or 46.6 Hrs with multiplied resolution.
Page 12: Extended Capabilities
Extended capabilities: In addition to operating under control of a Host, option /L of the I/O PLEXER has the ability to perform local control functions without the Host. Local control functions (LCF’s) can insure the continued safe operation of closed loop control should the Host or its communication link fail.
Page 13: Specifications
Specifications Network Communications: duTec supports several standards for transmitting serialized I/O data between the Host computer and the I/O PLEXERs. In addition to hardwiring, built in modem control lines allow the use of telephone, fiber optic, and radio modems at baud rates of up to 38,400.

Page 17: Installation 2
Power connections are made at the 3 position terminal block located on the right end of the I/O PLEXER. No. 8 captive wire clamps accept 10-16 AWG wire or spade lugs. The terminal block cover need not be removed to install wiring.
Page 18: Digital Expander
Digital Expander The I/O PLEXER Digital Expander (IOP-DE) Receives its power and signals from the I/O PLEXER via the included 24 pin keyed ribbon cable (duTec part #CE-24) No other power wiring is required. See page 2-14 2 - 2...
Page 19: Designing The Network
Installation 2 Designing the network In order for the I/O PLEXER to share its data with the Host computer, it must be linked via a serial connection. This link can be hard-wired using an RS-232 link (less than 50 Ft), or an RS-422/ 485 twisted pair connection where the wire run between devices is less than 5000 Feet.
Page 20 (plus recommended ground shield) RS-422, or single twisted pair (plus recommended ground shield) RS-485. The Host to first I/O PLEXER can be any of the three, but because most Hosts are equipped with an RS-232 port. This is used most often providing the distance is less than 50 feet.

Page 22: Network Type Switches
Installation 2 Network Type Switches Based on the selected network configuration, each I/O PLEXER must be set up before communications can begin. This is done with the network switches shown below in figure 2-5. Figure 2-5 Connectors, Switches, and Indicators 2 - 6 Artisan Technology Group - Quality Instrumentation ...
Page 23: Repeat
Host. Sequential display reads L3 If there is only one I/O PLEXER in a network it is designated as Last Unit. For the network layout the sequential display indicates the letter L followed by 1, 2, or 3. As shipped I/O PLEXERs are setup as L3, Last Unit. This change is not part of the push-button sequence.
Page 24: Communications Wiring
AT or XT connection is used. A duTec cable can be used for this purpose (IOPN-AT, IOPN-XT, or IOPN-AXT). In addition to the Host to I/O PLEXER wiring, the installer should confirm that the network type switches are set in the RS-232/ RPT positions and that both CTS/RTS jumpers are in the horizontal position as shown.
Page 25: Modem To I/O Plexer - Rs-232
They are request to send (RTS) and Clear to send (CTS). An active high RTS signal from the I/O PLEXER advises the modem that data is available. When the modem is ready to accept data, it places its CTS line active high to the I/O PLEXER thus initiating the data exchange.

This connector mates with Molex shell, number 50-57- 9005, and used pins, 16-02-0103. In addition to the Host to I/O PLEXER wiring, the installer should confirm that the network type switches are set in the correct positions, multidrop, repeat, or last unit.
Page 27: Host To I/O Plexer- Rs-485
Another option is to use an external terminal block or leads between the clamp terminal block and Molex connectors. In addition to the Host to I/O PLEXER wiring the installer should confirm that the network type switches are set in the correct positions, multidrop, repeat, or last unit.

Page 30: Adding Digital Expanders
Installation 2 Adding Digital Expanders: Up to three Digital expanders may be connected to any I/O PLEXER which is equipped with a “/3+” option (see page 1-8). These chassis are attached to the main unit via a ribbon cable supplied with the Digital Expander. Normally, power is supplied through this cable.
Page 31: Module Wiring
There must be nothing connected to the screw terminals corresponding to these module positions. The source of analog inputs is external to the I/O PLEXER in most circumstances. Exceptions are those of RTD and Type 590 temperature...

Page 33: Analog Outputs
Installation 2 Analog outputs: Modules should NEVER be installed or removed while power is applied to the I/O PLEXER. Note: Analog modules normally run hot to the touch Both voltage and current output modules provide their own isolated power output. This eliminates the need for external power supplies and insures electrical isolation between each output.
Page 34: Digital Inputs
Modules should NEVER be installed or removed with power applied to the I/O PLEXER. The source of the discrete signal to be monitored is external to the I/O PLEXER in most circumstances. The IDC5S digital input dry contact sense module is an exception.
Page 35 Installation 2 Digital outputs: Modules should never be installed or removed while power is applied to the I/O PLEXER. ODC5, ODC5A, OAC5, and OAC5A digital output modules are used to switch external power supply loads on and off. Because they contain a protective reverse diode, the ODC5 and ODC5A output modules are polarity sensitive and operate correctly only when the “=”...

Page 37: Chassis Setup
Chassis Setup Figure 3-1 Connectors, Switches, and Indicators During the setup phase of an I/O PLEXER system, the main chassis are given specific values for unit address, network baud rate, and protocol pass type. A momentary pushbutton and seven segment display provide access to these parameters.
Page 38: Sequential Display
16 I/O PLEXER network connections. The loading of selected function addresses into the I/O PLEXER is explained after the description of baud rates and protocol handshake type found on page 3- *** Any function address not supported by the unit will default to the master unit control address to conserve network address usage.
Page 39: Protocol Handshake Types
The sequential display indicates the letter P followed by 2 or 4. As shipped I/O PLEXERs are set up for 2 pass; the sequential display indicatesP2. The actual setting of the handshake protocol type into the I/O PLEXER is detailed beginning on page 3-4.
Page 40: Changing Setup Parameters
The display will continue to cycle through the setup sequence until there is a full cycle with no changes. The I/O PLEXER then stores all values in EEPROM for automatic use following each power cycle. If desired changes were not implemented correctly , line power can be recycled and setup via pushbutton procedure can be repeated as required.
Page 41 The pushbutton method can always be used to return to the OFFSET mode. Hardware Error Codes: When the I/O PLEXER is initially turned on, it goes through internal self test. If anything is not correct, the appropriate error code will flash on the sequential display.
Page 42 If the Recv. LED is on constantly the RS-422/ 485 wiring is probably backwards. Once signal to the I/O PLEXER is verified, a valid instruction should be sent to the unit to initiate a response. Send an “Identify station type” “F” instruction (see appendix C,C) Be sure to send the entire instruction within 10 seconds as the I/O PLEXER will ignore instruction that take too long to finish.
Page 43 Host receiver. Once a proper response is received at the Host, repeat the procedure for any additional I/O PLEXER to be added to the network. When all chassis are checked out, the terminal software can be replaced with the actual Host software for this project.
Page 44 I/O PLEXER instruction set. This program incorporates a menu driver “step by step” approach to building any instruction. Once an instruction is developed, it may be sent to the I/O PLEXER. MAGIC will then report the I/O PLEXER’s response to that instruction thus completing one Host to I/O PLEXER exchange.
Page 45: Equivalent Rs-232/ 422 Communications Circuit
Figure A-1 Electrical Equivalent Circuit Figure A-1 Shows the equivalent RS-232/ 422 Communications circuit for the I/O PLEXER. When switched to “Last Position” the 150 Ohm network terminator resistors are in place. Positions A-D of SW2 allow the removal/ installation of network biasing resistors used to suppress line noise when all transmitters are at rest.

Page 47: I/O Performance
Appendix B I/O Performance The I/O PLEXER samples individual analog inputs at the constant rate of 100 samples per second. The effective sample rate per channel is determined by the total number of channels to be sampled. Input data throughput is based on the time from the beginning of the first character of an instruction to the end of the last character of the response.
