Communications Unit Connection Diagram
• The RS-485 connection can be either one-to-one or one-to-N. A maxi-
mum of 32 Units (including the host computer) can be connected in one-
to-N systems. The maximum total cable length is 500 m. Use AWG24
(cross-sectional area: 0.205 mm
2
) to AWG14 (cross-sectional area:
2.081 mm
2
) shielded twisted-pair cable.
