Cable Networks/Permanent Connections
4.2.1 Enable Multipoint Mode with DIP Switches
Multipoint operation makes it possible to run multiple modems on a two-wire cable network.
To activate the multipoint operation mode, set up the FP Modem-EU as follows:
PC/RTS mode
PLC mode
Transparent mode (V1.21)
(S95=3 set by DIP1)
Transparent mode (V1.21)
(only if S95 not zero)
DIP switch 4 is used to select the baud rate of the RS232C interface:
PC/RTS mode
PLC mode
(before V1.2)
PLC mode
Transparent mode
(V1.21)
*8o1 stands for: 8 data bits, odd parity, 1 stop bit
Selectable baud rate:
To select a setting other than with DIP switch 4=ON, carry out the following procedure:
1. Set all DIP switches to OFF (to enter the dial-up, command mode)
2. Use a terminal (program) which is set to the desired RS232C baud rate and
format
3. Power up the modem and enter AT (or AT&F to recall the factory settings)
The modem should respond with OK.
If you optionally want to disable the automatic baud rate detection (command
mode), you should use the "AT*W=baud,data,parity,stop" command (see
"Command Tables" on page 68).
4. Enter AT&W to save the settings
