Interfaces

Front Panel

RST      Reset button is accessible on the front panel using pin of diameter under 2 mm (pencil tip, etc.). It re-initializes all modem functions. The modem must be reset immediately on inconsistent operation appearance, before starting the maintenance diagnosis phase. This reset, like duration power cut-off, has no effect on the status of configurations previously loaded into the modem.

SET      Set button is used for entering command mode (see “Entering Command Mode” section), which allows modem configuration.

PWR     In data mode PWR LED is ON when modem is power supplied and in proper function; PWR LED is OFF in case of: power supply is not present or modem is in malfunction. PWR LED blinks slowly (100ms / 1sec cycle) as an indication of command mode. PWR LED blinks fast (100ms / 100ms cycle) when modem has locally initiated some of the test modes. PWR LED blinks slowly (1Sec / 1sec cycle) when modem is remotely brought to some of the test modes.

TXD      Transmit LED indicates LED transmitted on TXD pin of RS232 interface.

RTS      Request to Send LED indicates state of RTS pin of RS232 interface.

RXD     Receive LED indicates data received on RXD pin of RS232 interface.

DCD     Data Carrier Detect LED indicates the presence of in-channel carrier with level higher then predefined receive level.

DIAG-Command/Boot-loader serial interface

This connector is RJ45 8 pin female type connector. It provides the interface between the modem and terminal unit in command mode and in firmware upgrade process. The following table gives the allocation and function of each pin.

RS-232C / Data serial interface

 

This connector is a SUB D9 pin female type connector with screw locking. It provides the interface between the modem and remote terminal unit or data processing equipment in data mode. The following table gives the allocation and function of each pin.

Line / Analog interface

This connecter is a SUB D 15 pin female type connector with screw locking, which provides:

  • Interface between 2 or 4 wire analog line and the modem;
  • The fail output

On the same connector modem has interface intended for communications management with a radio interface (squelch and alternate) which are not supported in current firmware version. Figure below depicts analog line interface.

Power / Power Supply

Power supply connector is a 2-position screw plug type (for 2-2.5 mm² wire) used for connecting the modem to a DC power supply. Polarity is irrelevant. Maximum consumption is 3VA. Table of possible voltage options are shown below.

IG202T-R38 Rack 1U (up to 3 modems)

IG202T-R38 Rack 3U (up to 14 modems)
