2.3 Installing the Standalone Modem
2.3.1 Power Supply Connection
WARNING: Do not connect the modem to the
mains socket or to the telephone line at this stage.
The standard modem is supplied for use on 230 VAC mains supplies. The
voltage for which it is set is shown on the rear panel. Check that the
voltage shown is correct for your mains supply before proceeding further.
The mains cable from the modem is provided with a moulded plug for
connection to a standard mains socket outlet. If this plug is not suitable for
your socket, refer to the Appendix entitled 'Country-Specific Information'
for details of how to change it. Do not use an adapter.
A special version of the modem is available for use on 24 to 48 VDC
supplies. Details are given in the Appendix entitled 'Technical Guide'.
When you are sure the modem is correctly rated for your mains supply,
ensure that the modem is switched off (
0
position) then plug the mains lead
into the mains supply. Do not switch on until all other connections have
been made.
2.3.2 DTE Port Connection
The synchronous data DTE must be connected via a cable to the modem's
DTE interface connector. A straight-through 25-way cable will be suitable
for many synchronous terminals, but there are some which require a cross-
over cable. If in doubt, consult the DTE's manual for connection details
and compare with information in Appendix B of this manual. See Figure 2-
1.
2.3.3 Command Port Connection
The command port allows you to connect a separate asynchronous
command terminal for entering commands, as shown in Figure 2-1.
The port is provided on a stereo jack socket. An adapter cable to convert
this to a standard 25-way D-type socket (ISO 2110) is provided (see
Appendix B for details).
The data format and speed for the command port is fixed at 7 data bits,
even parity, 9600 bps.
