4.0 CONFIGURATION
The Model IM2RC/I-100B module plugs into Patton’s 3088RC and
2701RC modems to provide Ethernet LAN extension. The IM2RC/I-
100B 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. 3088RC and
2701RC) to make the following settings.
1.
Bit Rate:
The DTE rate setting of your base unit corresponds to the
throughput of your IM2RC/I-100B bridge module. Use higher speeds
to allow maximum throughput to your extended LAN. Use lower
speeds to limit the access of your extended LAN.
Note
The IM2RC/I-100B only supports synchronous speeds.
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/I-100B, DISABLE, the “Enable Loop from
DTE” Switch on the front function card (3088RC or 2701RC).
4. All other base unit settings depend upon your application and on the
application medium (twisted pair or coaxial cable).

Note
Unit “A” and Unit “B” are arbitrarily chosen. It does not mat-
ter which unit is “A”, and which is “B”.
