3.1.4 REVERSIBLE “DAUGHTER BOARD”
The Model 1180RC/1184RC supports both RS-232 and V.35 elec-
trical interfaces for the terminal connection port. Which electrical inter-
face is active is determined by the orientation of the small reversible
daughter board on the front card (see Figure 3, below). The daughter
board is clearly marked “This side up for RS-232” and “This side up
for V.35”. Note: When plugging the daughter board into the socket, the
arrow should always point toward the
front panel of the PC board.
3.2 REAR CARD CONFIGURATION
The Model 1180RC/1184RC is compatible with four single-fiber
rear interface cards. Figure 4 (below) shows a rear view of each of
the cards.
Figure 5 (below) shows each of the possible interface port combi-
nations and their part numbers.
