Installation

Connecting the Probe

5.Perform any other instructions as required by the modem manufacturer. If you have any problems with the modem, contact the modem manufacturer for assistance.

Install the LanProbe Modem

You need the following list of equipment to install the LanProbe 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 LanProbe modem:

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

2.Connect an RS-232C cable from the modem’s RS-232C port to the LanProbe’s RS-232 port. A null modem cable cannot be used for this connection.

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 place the modem power switch to on.

5.Perform any other instructions as required by the modem manufacturer. If you have any problems with the modem, contact the modem manufacturer for assistance.

Configure the Management Station and LanProbe

Refer to your NetMetrix documentation for information on configuring the management station for use with a modem. Verify that the packet retransmission timeout is set appropriately. For example, a 1500-byte SNMP packet requires about one second to transmit over a 9600 baud connection, with another one second for the reply. A packet retransmission timeout of three to five seconds is appropriate for this example.
