CHAPTER 4: Installation
4. Thread the bare ends of the four wires into the
four screw terminals on the SHM-B Sync’s board
marked RX+, RX–, TX+, and TX–. Refer to
Figure 3-1 on page 11 for the location of these
terminals. Bear in mind as you do this that the
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
below.

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. Close the unit’s case.
