ASCII command:
1.
$AACONNDD ;Set DO(n) to DO Auto-Off Time Mode
2.
$AA9DNNHHHHLLLL ;Set high /low delay width of DO(n)
3.
#AA1NDD ; Write DO channel to active
Example:
Set the channel-0 of DO to active and the channel-0 of D/O will be auto-off(inactive) after 3 sec.
1. $01CO0006 - Se to DO(0) Auto-Off Time Mode for DO "Low->High->Low.
(output low is active (ON), outputt high/open is inactive)
2. $019D0017700001 - Set DO High delay time(HHHH=3000ms) and Low delay time(LLLL= 0.5ms).
(For " Low->High->Low Auto-Off Time mode" LLLL always "0001")
3. #011001 - Write DO channel(0) to active
wait DO auto-off time (3sec)…….....,
...
4. the DO channel(0) auto-off from active to inactive.
Example:
Set the channel-1 of DO to inactive and the channel-1 of D/O will be auto-off(active) after 3 sec.
1. $01CO0107 - Se to DO(1) Auto-Off Time Mode for DO "High->Low->High.
(output low is active (ON), outputt high/open is inactive)
2. $019D0100011770 - Set DO High delay time(HHHH=0.5ms) and Low delay time(LLLL= 3000ms).
(For " High->Low->High Auto-Off Time mode" HHHH always "0001")
3. #011100 - Write DO channel(1) to inactive
wait DO auto-off time (3sec)…….....,
...
4. the DO channel(1) auto-off from inactive to active.
