If no external power supply is
connected, then the pulse outputs
default to the internal +5V supply.

 RS-422 compliant differential pair (normal and inverse) outputs are provided for pulse outputs
“Pulse output 1(P1A, /P1A)” and “Pulse output 2 (P2A, /P2A)”; each pulse output can thus be
connected to both single-ended and differential interfaces.
 “Pulse output 1(P1A, /P1A)” and “Pulse output 2 (P2A, /P2A)” default to a 0 to +5V signal
range; if a higher output voltage is required, then an external voltage source up to +24VDC
may be connected across POUT +V and DGND to define the required voltage.
 “Pulse output 1” and “Pulse output 2” may be user-configured for either independent or
quadrature operation.
 In independent mode, “Pulse output 1” and “Pulse output 2” run independently and may be
configured with different pulse rates:
