Maximum Cable Length for SS200V Communications

To achieve reliable wired communications, the selected baud rate must be compatible with

the length of the cable run. e table below shows the cable length recommendations for

wired communications (see Table B.2):

Baud Rate RS-485

115.2 300 ft. (91.4 m)

57.6 600 ft. (182.9 m)

38.4 800 ft. (243.8)

19.2 1000 ft. (304.8 m)

9.6 2000 ft. (609.6 m)

Table B.2 – Maximum Cable Length for Wired Communications

Given the power and communication requirements listed above, here is a summary of some

power and communication cable guidelines (see Table B.3):
