Conﬁguring the DL3100 4-3

Connecting the Terminal Port through a Modem

To connect the terminal port of the DL3100 through a modem, you need a

DB-25 to DE-9 null modem cable.

If the comm port baud rate is 9600, the distance between the TERMINAL

port and the modem cannot exceed 50 feet. You can increase the distance if

you reduce the baud rate.

To connect a modem to the TERMINAL port:

1. Make sure the connection is a DB-25 to DE-9 null modem cable.

2. Make sure the DL3100Õs baud rate, parity bit, and stop bit settings

match the modemÕs.

If they do not, change the settings on the DL3100 using the front

panel controls.

3. Using the DB-25 to DE-9 RS-232 null modem cable, connect the

modem to the appropriate DE-9 connector on the DL3100Õs rear

panel. (Figure 4-1.)

4. Connect the modem to the phone line.

Connecting Multiple Units in a Daisy-chain

You can connect up to twelve DL3100 units in a daisy-chain, for centralized

network monitoring and management capabilities.

To daisy-chain DL3100 units, use a cable with DE-9 connectors (available

from Digital Link).

Connect multiple DL3100 units in a daisy-chain:

NOTE: Digital Link can provide 9-pin to 25-pin adapters, as well as

null-modem adapters if they are required.
