• 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 a shielded,
AWG24 to AWG14 (cross-sectional area of 0.205 to 2.081 mm
2
) twisted-
pair cable for the E5CN, E5EN, or E5AN. Use a shielded, AWG24 to
AWG18 (cross-sectional area of 0.205 to 0.823 mm
2
) twisted-pair cable
for the E5GN.
