Figure 2-11: Ground and Data Connections for Linking RCS-2700 Units
You can “daisy-chain” the connections from unit to unit to connect all of the
units together. Use wires of two different colors to connect the ground and data
pins from unit to unit. You can use twisted pair or shielded wire. If you use
shielded wire, connect the shield to the ground pin.
The length of each section of wire between units should be less than 6 feet (2
meters), although typically less than a foot of wire (30 centimeters) should be all
that is necessary. The units should be linked as shown in the Figure 2-12. It does
not matter in what order the main and numbered expansion units are connected,
although connecting the units in numbered order should result in an installation
that is more organized.
