3.1.1 Reversible Interface Driver Board
The Model 1092ARC Series features switchable interface driver
boards that allow a wide range of DTE interface connections. Figure 3
shows the Interface Driver Board on the top of the 1092ARC PC board.
Follow the instructions below to select the correct interface for your
application:
1. With the 1092ARC pulled out of the rack or clusterbox chassis,
locate the driver board on the top of the 1092ARC front card.
2. Lift the interface board gently off of the PC board.
3. Locate the correct interface on the bottom of the driver board.
For example, the RS-232/V.35 interface board is marked
“THIS SIDE UP FOR RS-232” on one side and
“THIS SIDE
UP FOR V.35” on the other side .
4. Re-orient the interface board into the socket with the
appropriate interface pointed UP and with the arrow pointing
toward the front panel of the Model 1092ARC PC board.
5. Push the Interface Driver Board gently onto the socket and re-
install into the rack or cluster system.
