Connect signal ground of the host
and the driver without fail.
Note:
[1] As well as being output in the line driver, only the Z-phase signals are output to the pin 19 (CZ) in the
open collector. When using this CZ signal, be careful not to be subject to the noise impact.
[2] Use a line receiver (AM26C32 or equivalent) for receiving the output pulses. Then, attach ppropriate
terminating resistor between inputs of the line receiver.
[3] In the Z-phase signal output, be aware that the logic of line driver output (OZ) is the reverse of that of
the open collector output (CZ).
[4] Use the pulses at less than or equal to the maximum output frequency 4 Mpps (after quad edge
valuation).
