SHORT-HAUL MODEM-B SYNC (SHM-B SYNC)
wires must run from TX+ in one SHM-B Sync to
RX+ in the other, and from TX– to RX–, RX+ to
TX+, and RX– to TX–, as shown in Figure 4-1 on
page 14.
5. Wrap the nylon cable tie provided with the SHM-B
Sync around the four wires, threading it through
the two holes in the circuit board just behind the
terminal block. Pull it tight to secure the wires in
place against the board. Remove the excess nylon
tie with a pair of scissors or wire cutters.
6. Plug one end of an RS-232 cable into the DB25
female connector on the back of the card. Avoid
running this cable farther than 50 ft. (15.2 m).
Refer to
Section 5.2
for information about
supported RS-232 signals and about how this cable
should be pinned.
7. Slide the card into the front of the chosen vacant
slot in the card chassis: Slide it carefully along the
grooved tracks at the top and bottom of the slot
until it reaches the three “power pins” at the back
of the chassis. Make sure that the card’s three
power sockets have mated with these pins before
applying force to fully seat the card; otherwise,
when you push the card into the back of the
chassis, you might damage the card and the chassis.
