Important Notices Because of the nature of wireless communication, transmission and reception of data can never be guaranteed. Data may be delayed, corrupted (i.e., have errors), or be totally lost. Significant delays or losses of data are rare when wireless devices such as the Integra-TR are used in a normal manner with a well-constructed network.

1 PRODUCT OVERVIEW This document provides the information required for the operation and preventive maintenance of the Integra-TR integrated wireless modem. This manual is intended for system designers, installers and maintenance technicians. The Field Programming Software for the Integra is the professional service installer interface. The Field Programming Software should never be made available to unqualified personnel. 1.
1.3 PHYSICAL DESCRIPTION Integra-TR consists of a logic PCB (which includes modem circuitry) and a radio module. Each logic PCB and radio module are matched together and characterized in the factory to optimize performance as an intelligent unit. The two boards then slide into the rails of an extruded aluminum case. DTE connection is made via a front panel connector. Power is applied through a rear panel 4-pin connector which includes two programmable analog connections usable as inputs or outputs.
CS/SYN RX/TX RD/TD Off No RF RX carrier Green Receive carrier present Red (Reserved) Off No RF RX carrier Green Receiving network data Yellow Synthesizer unlocked Red Transmitter is on Off Idle Green RX data outgoing from RS-232 port Red TX data incoming at RS-232 port (or Buffered in CSMA Mode) 1.4.3 COM PORT Integra-TR is configured as DCE. DTE devices should be connected using a nine-conductor pin-to-pin straight cable (PN 6974008-408).
For DTE that lack RTS control, Integra-TR can operate in DOX (Data Operated Transmit) mode with only Transmit Data, Receive Data and Ground. This 3-wire interface is shown in Figure XX. Figure 3 - 3-wire Interface 1.4.4 SETUP PORT The Setup port uses a DE-9 female connector configured as DCE. Signals are described in Table 3.
1.5.1 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. 1.5.2 POWER – I/O CONNECTOR The Integra-TR power requires a regulated power source of 13.3 VDC nominal (10-16 VDC MAX) negative ground with a 3.0 A rating.

Your modem is now ready for use. 3 NETWORK APPLICATIONS 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. Below is an overview of common configurations. 3.
Figure 7 - Point-to-Point System 3.2.2 POINT-TO-MULTIPOINT SYSTEM A basic point-to-multipoint system is shown in Figure XX. Figure 8 - Point-to-Multipoint System (simplex or half-duplex) If a half-duplex radio network is used (i.e. two frequencies with the master station transmitting and receiving on the reverse pair from the remotes), the master station can be either full duplex or half-duplex. If a simplex radio network is used (i.e.

3.2.3 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 11. The tail circuit assembly may be used in any of the network types described in the preceding sections. Figure 11 - Landline (Tail Circuit) Note: The line modems should be full-duplex units.

The Remote ID is selected from the list of Remote IDs set up in the Diagnostic IDs and Alarms screen. Diagnostic Select Selected Remote ID This button allows the user to gather Offline Diagnostics from the selected Remote ID only. Remote ID List This button allows the user to gather Offline Diagnostics from all the IDs in the list of Remote IDs (including the local unit).
interfaced with will output Online Diagnostics as they are received. Using Online Diagnostics does not require suspension of network operation. Online Diagnostics are subject to alarm conditions defined in Section XXX Diagnostic IDs and Alarms. When Online Diagnostics are received and a diagnostic field falls outside the alarm limits, value X will be designated as less than < or greater than > the allowed parameters.
RevP Reverse Power displays the approximate measure of reverse (reflected) power of the unit transmitting the diagnostics. This is represented as “Good” if the reverse power is within acceptable limits and is represented as “Bad” if the reverse power is too high. The threshold is set to approximately 1/4 the forward power. Remote RSSI If these are the diagnostics from a Remote Station, Remote RSSI indicates the RSSI level of the Remote Station from the last received transmission.

5 NETWORK OPTIMIZATION Detailed system engineering is beyond the scope of this manual. However, there are some simple tips that can be used to optimize performance of a radio based SCADA or telemetry system. 5.1 CHOOSE THE BEST PROTOCOL Some SCADA devices allow a choice of more than one operating protocol. In some cases, performance can be improved by selecting a different protocol. Contact Technical Service for assistance. 5.
Some representative performance values for 9600 b/s operation are given below. These values assume that the units are correctly aligned and installed in a quiet location. Environments with high electrical or RF noise levels will require an increase (less negative) in the numbers shown to achieve a given level of reliability. -100 dBm Approximately 50% reliability. Fading may cause frequent data loss. -90 dBm Approximately 90% reliability. Fading will cause occasional data loss.
6 DEFINITIONS Dribble bits Extraneous bits delivered at the end of a data transmission. These bits are equivalent to a “squelch tail” in voice systems. COM Port The Communications Port of the wireless device. This port is configured as DCE and is designed to connect directly to DTE. CTS Clear to Send. An RS-232 output signal from Integra-TR indicating that it is ready to accept data (used in RTS mode). DCE Data Communications Equipment. This designation is applied to equipment such as modems.
