Install the Management Station Modem

You need the following list of equipment to install the management station’s modem:

Hayes-compatible 300 to 38.4 K baud modem

zRS-232C (straight through) modem cable

Modular phone cable with RJ-11 connectors or equivalent

Use the following procedure to install the management station’s modem:

CAUTION Turn off all equipment prior to making cable connections.

1.Place the modem close enough to the management station to not violate the 50-foot RS-232C distance limitation.

2.Connect the RS-232C cable from the modem’s RS-232C port to the management station’s serial port. Take care in selecting the appropriate serial port on the management station (COM1 or COM2, for example).

3.Connect the RJ-11 modular phone cable from the modem To Line port to the telephone jack.

4.Connect power to the modem and turn on the modem power switch (not required for a PC internal modem).
