D-Wire External Sensors

The ports on your Cell16 labeled Digital Sensors support up to 16 D-Wire sensors. Your Cell16 powers and
communicates with your D-Wire sensors via simple RJ-11 connections. You can chain your 16 sensors to the D-
Wire port on the Cell16 .
The max cable length depends on the number of sensors daisy chained together. The cable lengths and
corresponding number of sensors can be seen in the table below.
