High Speed Pulse Output (Pins 3, 5, 7, 9)
This quadrature pulse output is a high-speed RS-422 drive output with an
output rate up to 5MHz. This pulse output uses an RS-422 transceiver to
generate its output signals, and so should be connected to an RS-422
transceiver on the receiving end. These pulse outputs can be connected to a
PLC high speed counter card for fine length resolution and high-speed velocity
measurement.

If you need to convert the differential RS-422 level pulse signals to TTL levels,
Beta LaserMike recommends that you use the following circuit:

The High Speed Pulse Output can be reconfigured to output several different
status outputs using the High Speed Pulse Output Configuration setting.
