PDS Series User Manual ( V1.4, Oct. 2009) ----- 144
<3> Output command value: If the Host Watchdog Timeout status is clear, and the
user issues a digital output command, to the module to change the output value, such as
@AA (Data) or #AABBDD, the module will respond “success” (receive >).
Latch Digital Input
If, for example, the user connects a key switch to the digital input channel and wants
to read the keystrokes, the key input is a digital input pulse, and the keystroke will be lost.
By using command $AA6 to read the A and B positions, the response would be that there
was no keystroke and the keystroke information will be lost. The read latch-low digital
input command, $AAL0, will solve this problem. When issuing a
$AAL0 command at the A and B positions, the response will denote
that there is a low pulse between A and B position signifying a keystroke.
