The RS-485 connection can either be one-to-one or one-to-N. Up to
32 units including the personal computer can be connected one-to-N.
For 900-TC8 & 900-TC16:
Use shielded, twisted pair cable
(24…14AWG), and keep the total length to 500 m or less.
For
900-TC32:
Use shielded, AWG24 to AWG18 twisted pair cable.
