High Speed Position Capture (The Latch Function)
Often it is desirable to capture the position precisely for registration applications. The DMC-13X8
provides a position latch feature. This feature allows the position of the main or auxiliary encoders of
X,Y,Z or W to be captured within 25 microseconds of an external low input signal. The general inputs
1 through 4 correspond to each axis.

1 through 4:
IN1 X-axis latch
IN2 Y-axis latch
IN3 Z-axis latch
IN4 W-axis latch
Note: To insure a position capture within 25 microseconds, the input signal must be a transition from
high to low.
high to low.
The DMC-13X8 software commands, AL and RL, are used to arm the latch and report the latched
position. The steps to use the latch are as follows:
position. The steps to use the latch are as follows:
1. Give the AL XYZW command to arm the latch for the main encoder and ALSXSYSZSW
for the auxiliary encoders.
2. Test to see if the latch has occurred (Input goes low) by using the _AL X or Y or Z or W
command. Example, V1=_ALX returns the state of the X latch into V1. V1 is 1 if the
latch has not occurred.
latch has not occurred.
3. After the latch has occurred, read the captured position with the RL XYZW command or
_RL XYZW.
Note: The latch must be re-armed after each latching event.
