  • Page 12 1.6 IF A PROBLEM ARISES... Component level repair is not recommended on the Integra-TR. DRL’s factory is best equipped to diagnose problems and make component level repairs. Contact Technical Service before returning equipment. A technician may suggest a solution eliminating the need to return equipment.
  • Page 13 The RMA number helps locate your equipment in the repair lab if there is a need to contact Dataradio concerning the equipment. Units sent in for repair will be returned to the customer re-tuned to the current Dataradio Test and Tune Procedure and will conform to all specifications noted in this section Customers are responsible for shipping charges (to Dataradio) for returned units in warranty.
  • Page 14 DRL’s Technical Service. 1.10 NETWORK APPLICATION Integra-TR is suited to a variety of network applications. Its primary design goal was to satisfy the needs of SCADA systems using RTUs or PLCs in either point-to-point or point-to-multipoint service.
  • Page 15 Figure 1-3 Basic Required Connections 1.10.3 COMMON CHARACTERISTICS The networks described in this section share common characteristics: 1. The network speed (2400, 4800, 9600 and 19,200 b/s) must be the same for all stations in a network. 2. Transmission of online diagnostics may be enabled or disabled at any station or stations without affecting their ability to communicate with other stations.
  • Page 16 If a simplex radio network is used (i.e. a single frequency for all stations), we recommend that the master Integra-TR be set to “master”, the remotes to “remote” and all units to remote “selective” data delivery. This will prevent remote stations from hearing each other's responses.
  • Page 17 1.10.6 EXTENDING A LANDLINE (TAIL CIRCUIT) Integra-TR may be used to extend a landline circuit (giving access to difficult locations, etc.). This type of connection is called a “tail circuit” and is shown in Figure 1-9. The tail circuit assembly may be used in any of the network types described in the preceding sections.
  • Page 18 Some point-to-point FDX landline modems or line drivers may require the use of DOX mode and an alternate pinout for DTR, DCD, CTS and RTS as shown in Figure 1-11. DE-9M DE-9M Figure 1-11 DCE Crossover Cable for DOX Mode 1-16 Part No.

  • Page 21 2.2.2 Connection to DTE Integra-TR is configured as DCE. Most DTE should be connected using a nine-conductor pin-to-pin “straight” cable. Some RTUs or PLCs may require a special cable to route the signals correctly. See the documentation for your data equipment for further information.
  • Page 22 2.2.4 COM Port Baud rates from 300 to 19200 are supported. Integra-TR's are factory set (default) for 9600 b/s, 8 bits, no parity, and 1 stop bit. Unless required by your operating protocol, we advise restricting port speed to be equal to or less than the RF network speed.
  • Page 23 Figure 2-2 COM and Setup Port Connectors Pin Locations 2.2.4.2 Wire Connection (DOX) Field Programming Software For DTE that lack RTS control, Integra-TR can operate in DOX mode (Data Operated Transmit) with only Transmit Data, Receive Data and Ground (“3-wire interface”).
  • Page 24 2.3.1 Heat Sink The rear panel heat sink is essential for proper operation of the Integra-TR transmitter. The unit must be mounted in a location that permits free air circulation past the heat sink. Cooling will be best if the fins are vertical.
  • Page 25 Field Programming Software. The programming cable (included in the Programming Kit - DRL part number 250-4008-001) is connected from the Setup Port on the Integra-TR to the PC’s COM port configured as the Primary Port. The Port Settings screen of the Field Programming Software is accessed via the Utilities pull-down menu (see Figure 2-7).
  • Page 26 Selecting the Swap Com Ports button moves the Secondary COM Port settings to the Primary COM Port (and moves the Primary COM Port to the Secondary settings). Since Integra-TR programming is done through the Primary COM Port, this is useful when two units are connected to the Primary and Secondary COM Ports.
  • Page 27 See Table 2-4 for Communication Modes configurations. Table 2-4 Communication Modes Mode Description Sync/ESC with No HS Sends data using Sync/byte-stuffing protocol without handshaking. Buffered with No HS Sends buffered data without handshaking. Sync/Esc with RTS/CTS HS Sends data using the Sync/Esc byte-stuffing protocol with RTS/CTS hardware handshaking.

  • Page 29 (full channel units only) The Integra-TR is capable of selectable network speeds of 2400 and 4800 b/s quarter-channel units, 4800 and 9600 b/s for half-channel units, and 4800, 9600, 19200 b/s for full-channel units. Use the Integra-TR mode whenever feasible.

  • Page 37 The parameters can be viewed and/or edited with the Setup Modem/Radio Parameters screens. Note: Dataradio recommends a Read be done anytime an initial connection is made to the Integra-TR Setup Port before accessing the Setup Modem/Radio Parameters screen. This will help avoid writing erroneous parameters to the connected unit.

  • Page 49 Check timer settings Polling protocols issue a poll and wait a certain time for a response. Integra-TR adds a short amount of delay to each poll and response (typically in the order of 60 to 70 ms). Timer settings that are too short may cause erroneous indication of missed polls, in which case the application may retry or continue to cycle, ignoring the missed station.
