3.3 CONFIGURE THE REAR INTERFACE CARD
The Model 1092ARC Series has several interface card options: the
Model 1001RCM12545 (DB-25/RJ-45), 1001RCM13445 (M/34/RJ-45),
1001RCM11545 (DB-15/RJ-45), IM2RC/IA, or IM2R/F. Each of these
options supports one DTE interface connection and one 2-Wire/4-Wire
twisted pair line connection. Figure 4 below shows three interface
options. If you are using the IM2RC/IA or IM2RC/F rear cards, refer to
the IM2RC/IA or IM2RC/F manuals for configuration instructions.
Prior to installation, you will need to examine the rear card you
have selected to be sure it is properly configured for your application.
Each rear card is configured by setting straps located on the PC board.
To configure the rear cards, you must set the configuration straps.
Figure 5 below shows the orientation of these straps. Each strap can
either be on pegs 1 and 2, or on pegs 2 and 3. Sections 3.3.1 and
3.3.2 describe the strap locations and possible settings for each rear
card.
