Resolution
Maximum Length of I/O Bus
The Andover I/O Bus is a network. Networks are limited by cable lengths because
electrical signals lose power and distort as they travel along wire. The longer the wire,
the lower the signal strength. The following are the maximum cable length
specifications:
RS-485 2000 ft. (610 m)
FTT-10A 8858 ft. (2700 m) double termination
1640 ft. (500 m) free topology
