5.31 Technical note - dial up SETUP (WESTERMO)
This description applies to Westermo TD-32AC / TD-32DC modems.
5.31.1 DIP switch settings.
5.31.2 Connecting the modem to the cabinet.
The modem must be connected to Remote Port 1
1
or Remote Port 2 on the connection inter-
face board in the ILS cabinet. The baud rate for this port must be 9600 bps. The init string for
the port should be:
ATE0&C1&D2&W
5.31.3 Connecting the modem to the PC
The modem must be connected to COM1, 2, 3 or 4. The connection type in the NM7000 RMM
software must be set to Normal dial-up, the baud rate to 9600 bps and the init string should
be:
ATX3&C1&D2\N5&W
In the DOS version, the Use DTR to hangup check box should also be checked (the hang-up
string will then be ignored).

1.It is recommended to use Remote Port 2 on the ILS, because this port has a 16 byte FIFO
that reduces the CPU load caused by the serial communication handling. If the modem must
be connected to Remote Port 1, a cable with RTS (pin 4) connected to DSR (pin 6) both in the
modem-end, must be used. Also, RTS must not be connected in the ILS-end.
