1)
RS-422 complementary signals; with cable lengths exceeding 10m, we recommend using a
termination resistor R = 120 ohms between the wires (bk) and (bu/rd)
2)
RS-422: Pin A corresponds to A, pin L corresponds to B
3)
Without an external voltage reference the output for rotational speed output, angle and ready for
measurement returns a TTL level. If higher levels are required (for PLC inputs, etc.), a voltage
reference 5V<U<24V can be assigned via pin M.
