Connect to the first unit via its RS485 socket. To connect to further units, just
use standard microphone cable (or similar), come out of the first unit on the
Phoenix and simply parallel the three wires to the next device, and so on down
the chain as shown in the previous diagram.

We strongly recommend that you use screened cable for these connections and
be sure to ground one end of the screen. As the RS485 drivers used are “quarter
load” devices, the maximum number of nodes that can be connected together is
128, and the maximum theoretical cable length from the first node to the last
node is 1000 metres. This distance will be affected by the cable quality and to
some extent the operating environment.
