3.9.4 Using Long Cables (Vector)
RS232 data communication at 9600 baud will normally work fine for cables up to 50 m long,
depending on the environment. If you want to run a longer cable, you can switch to RS422 by
installing a different wiring harness you can get from Nortek.
You can also try using RS232 with longer cables by reducing the baud rate. Keep in mind that
RS422 is a more reliable means of communication than RS232 – changing environmental conditions
could cause RS232 communications to fail over a long wire without apparent reason.
You should consider voltage drop across the cable, particularly if you use the two highest power
settings. Design your power supply and cable so that the voltage stays below 16 VDC and never falls
below 9 VDC.
