Mod-8 to 25-Pin Connector
for Modem Connection
To connect to a local PC, skip to the "2. Connecting to the System".
1. Initialize the Site Modem
You must send an initialization (INIT) string to your modem before connecting it to
the system. You'll need a laptop (or other PC) on site to do this. There are three
parts to this procedure:
•
Connecting the modem to your laptop.
•
Entering the site modem INIT string into the Remote Maintenance program.
•
Sending and storing the INIT string in the site modem.
To connect the modem to your laptop (refer to the illustration on page 6):
1. Connect the modem power supply to the POWER jack on the back of the
modem.
2. Plug the male end of the 9-pin connector of the cable that is included with the
CNet modem into the RS-232 connector on the back of the modem.
3. Plug the 9-pin female end of the same cable into the serial port on the back of
your laptop (or PC).
Check the manuals that came with your computer if you're not sure
how to set up and connect the modem.
4. Plug the modem power supply into a 120 V AC receptacle and turn the unit on.
