Caution

Restrict cable length to less than 500’ (150m) for RS485/422

devices and 50’ (15m) for RS232 devices to avoid

communications problems.

Shielded cable must be used for long lengths or cables run in

an electrically noisy environment.

Do not run cables next to AC power lines or near sources of

electrical noise.

Be sure that the cable ends have been inserted all of the way

into mating connectors and are secure
