9.138 Comtech-CDM600

This page describes the device driver and the device window for the Comtech CDM-600 Satellite Modem. The driver actually supports the following modem operation modes:

SCPC
IDR overhead
IBS overhead
ASYNC overhead
Drop/Insert
AUPC

Device window pages

The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .

--- The IF parameters (frequency, level, etc.) and some global modem settings.
--- The modulator settings, transmit clocking.
--- The demodulator settings, receive clocking, doppler buffer.
--- The Reed-Solomon settings.
--- The IDR/IBS mode settings.
--- The ASYNC overhead settings.
--- The Automatic Uplink Power Control settings.
--- The data interface settings.
--- The Drop&Insert settings.
--- The receive quality.
--- The faults page.
--- The device info page.
--- The maintenance page. The configuration parameters described below are set at this page.

Configuration parameters

At the maintenance page of the device window there are a couple of configuration parameters which must be set to make the software talk to the device.

parameter	description
address	The modem's RS485 packet address. Valid addresses are 1..255, 1 is the factory default. You must set the same address than set at the modem's front panel
alarmMask	Sets the alarm mask conditions.
edmacMode	Embedded Distant-end Monitor And Control (EDMAC) Framing Mode
edmacAddress	Sets the range of addresses of distant-end units, which the master will forward messages for. (EDMAC)
ODUCommunication	Enables/disables the communications via the FSK link with a Comtech EF Data Transceiver (ODU)
esc	Enables/disables the IBS high-rate ESC.
circuitID	sets the user-defined Circuit-ID string, with a fixed! length of 40 characters
Serial	Remember to set the line parameters for the serial interface connected to the device. The recommended line setting for the use with the sat-nms software is 19200,N,8,1 . You have to set the same value at the device's front panel.

Remote interface

The CDM-600 provides a RS232 on the connector P4B at the rear panel labeled Remote Control . You can configure this interface on the front panel in the menu Configuration | Remote . Select Remote Control as operation mode, set interface type to RS-232 (with the fixed address 0, the baudrate to 19k2, and configure the interface to 8 databits, none parity,1 stopbit. To connect the modem to the sat-nms system use a 1:1 cable with the following pin assignment

--- CDM-600VLC
RX --- 23
TX --- 23
GND --- 55
