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
RS-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

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.
