1)
RS-422 complementary signals; with cable lengths exceeding 10 m, we recommend
using a termination resistor R = 120 ohms between the (wh) and (rd) wires.
2)
RS‐422: Pin 1 corresponds to A, Pin 4 corresponds to B.
NOTE
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.
