Integra-TR Characteristics:

Selectable network speeds of 2400 and 4800 b/s for quarter channel units, 4800 and 9600 b/s for half channel units as well as 4800, 9600 and 19200 b/s for full channel units

Backward compatible with the Integra-T for bit rate of 4800 and 9600 b/s (full channel units only)

One COM port for connection to DTE. Speed of 1200 - 19200 baud

One Setup port for configuration and diagnostics (speed fixed to 9600 baud, 8 bit, no parity, 1 stop bit)

Built-in 5-watt transceiver (adjustable 1-5 watts), operating in the VHF, UHF or 900 MHz communications bands. Half-duplex or simplex operation

Fully transparent operation with error-free data delivery

Allows transmission of “break” characters

DOX (Data Operated Transmit) or RTS mode

Stations may be set as “master” or “remote” to prevent remote stations from hearing each other in a simplex RF configuration

Full local and remote diagnostics

Two configurable I/O lines programmable as either 8-bit analog inputs or digital outputs

“12 VDC, negative ground” device

CWID provides the ability to program the unit to periodically identify itself on the air by sending the FCC Station ID in Morse code

Disable Tx w/Carrier Present configures the unit to prevent transmission when the radio channel is busy

Low power consumption modes: “sleep” and “suspend” modes (< 20 mA)

Multi-channel capability under system PLC control provides advanced network monitoring


Integra-TR supports:

1. Point to point Master-Remote or Peer-to-Peer configurations in simplex or half-duplex modes.

2. Point to multipoint Master-Remote configuration in simplex or half-duplex modes and offers full-duplex in dual-unit configuration.
