1)
Complementary signals RS422; with cable lengths exceeding 10m, we recommend
using a termination resistor R = 120 Ohm between the wires (wh) and (rd).
2)
RS422: Pin 1 corresponds to A, Pin 4 corresponds to B.
NOTE
These torque flanges are only intended for operation with a DC supply
voltage. They must not be connected to older HBM amplifiers with
square‐wave excitation. This could destroy the connection board resistances
or cause other faults in the amplifiers.
