1.178 EF-Data-SDM300

This page describes the device driver and the device window for the EF-Data SDM Satellite Modem. The driver actually supports the following modem operation modes:

The Drop/Insert mode is not yet supported by the driver, nor are the EF-Data AUPC and MUX options.

Not all SDM300 modems support all functions which are implemented in the device driver. If you try to select a function which is unsupported by this particular modem, the parameter will fall back to it's old value. Each missing attempt to set a parameter is recorded to the event log.

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 .

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 SDM300.

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
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,E,7,1 . You have to set the same value at the device's front panel.

Remote / local switching

The SDM300 does not provide a local/remote parameter which can be set at the device. Instead, the SDM300 is set to remote control with a command sent by the M&C/VLC. Touching one of the buttons at the front panel normally reverts the modem to local front panel control. The software repeatedly sends the "REMOTE" command to be sure that the SDM300 is in remote mode at any time. Hence, if you want to operate a SDM300 which is connected to a sat-nms system at it's front panel, pull out the remote interface plug from or set the device 'out of service' at the software's user interface.
