4.11 Pulser Input Signals PA and PB

The DMC5400 can accept the input signals from pulser or JOG device signals through connector X3. The
behavior of pulser or JOG device is as an encoder. The signals are usually used to generate the position
information which guides the motor to follow. The interface circuits are shown as Figure 4.12.
The X3 contains two +5V power supplies for pulser, if the signal voltage of pulser is not +5V or if the pulser is
distantly placed, it is recommended to put an optocoupler or line driver in between. Also, +5V and GND power
lines of X3 are direct from the PCI bus. Please carefully use these signals because they are not isolated.

4.12 Position Latch Signal LTC

The DMC5400 provides 4 position latch inputs, which can trigger the DMC5400 to capture the counter values. It
gives a precise position determination. The following table lists the relative signal name, pin number, and the axis
number.
