MC/EIA485
EIA connections
Terminate EIA485 connections at the Drive by connecting across the
related input terminals a resistor whose value equals the characteristic
impedance of the cable that is being used. When more than one Drive is
connected to an EIA485 link, a terminating resistor is required only at the
last Drive on the link.
