The Model IM2RC/IA module plugs into Patton’s1092ARC and
1095RC modems to provide Ethernet LAN extension. The IM2RC/IA
has no switches or jumpers and does not need to be configured.
However, factors such as the type of medium, throughput across the
link and clocking mode must be determined by the settings of the
baseband modems. Please refer to your baseband modem (i.e. 1092,
and 1095) to make the following settings.
1)
Bit Rate: The DTE rate setting of your base unit corresponds
to the throughput of your IM2RC/IA bridge module. Use higher
speeds to allow maximum throughput to your extended LAN.
Use lower speeds to limit the access of your extended LAN.
2)
Clocking Mode: Set the clocking modes on the base units
so that one unit is configured for Internal clocking mode and
the other unit is set for Receive Recover clocking mode.
3)
When using the IM2RC/IA, DISABLE, the “Enable Loop from
DTE” Switch on the front function card (1092ARC or
1095RC).
4)
All other base unit settings depend upon your application and
on the application medium (twisted pair or coaxial cable)
NOTE:
The IM2RC/IA only supports synchronous speeds.

NOTE: Unit “A” and Unit “B” are arbitrarily chosen. It does not matter which unit is
“A”, and which is “B”.

3.1 CONNECTING THE INTERFACE DRIVER BOARD
This package contains an interface driver board that allows you to
configure your front function card for ethernet operation. Figure 2
shows the Interface Driver Board connected to a Model 1095RC front
function card.
Follow the instructions below to connect the interface driver board
to the front function card:
1. With the function card (such as 1095RC, shown above) pulled
out of the NetLink rack or clusterbox chassis, locate the driver
board to be replaced on the top of the base unit front card.
2. Lift the old interface board gently off of the printed circuit
board.
3. Position the IM2RC/IA driver board on top of the function
card’s pc board with the sockets oriented toward the male
pins. Please be sure the label marked FRONT is
pointed toward the front of the function card (toward the
LEDs).
4. Push the Interface Driver Board gently onto the socket and re-
install the function card into the rack or cluster system.
