Wire Layout
Straight line, star, looped, and combination configurations are supported.
The straight line and the star topology are the recommended layouts. To simplify the illustrations, only the last
device is shown for most configurations. You can assume that other devices, both sensors and biCoders, are
connected along the length of the two-wire path. On a star configuration, the topology has multiple last devices.
Each device must separately meet the distance requirement.
While the loop topology might provide a more robust configuration, it is harder to trace the wiring errors that
might occur. For this reason, Baseline recommends the other topologies over the loop.
Wire Burial
Bury all wire at a depth appropriate to protect the wire from mechanical damage due to digging or aeration.
Baseline’s two-wire system operates under 30 VAC RMS, which is considered safe for shallow burial as outlined in
the National Electric Code. All installations should comply with local electrical codes.
