[ESC+IO] External Signal Input/Output
ESC IO Parameter Hexadecimal code

a,b,c(,dddddd)
Initial value None
When the power is OFF The set parameter is not maintained.
Valid range within items The set parameter becomes invalid.
Valid range and term of
command
Valid range between items The set parameter becomes invalid.
[Function]
Specify input/output of the designated pin number of the external signal.
[Format]
<IO>a,b,c(,dddddd)
- Parameter
a [Input or output]
0 : Input
1 : Output
b [Pin number] = Valid range : 1 to 14
c [Input/Output level]
0 : Low
1 : High
d [Timeout for input] = Valid range : 0 to 999999 (1 = 5 ms) (Omissible)
* When it is [Input], this parameter is the input timeout time.
When this parameter is omitted, the printer does not proceed to the next command analysis
until the next input from the designated port.
[Output time] = Valid range : 0 to 999999 (1 = 5 ms) (Omissible)
* When it is [Output], this parameter is the output time.
The signal level will be returned to the status before this command after the specified time
has been passed when this parameter is specified.
The signal will be output continuously at the specified level when this parameter is omitted.
[Coding Example 1]
Wait until HIGH level is input from the EXT5 pin (with 5 second timeout)
<A>
<IO>0,5,1,1000
<Z>
[Coding Example 2]
Output LOW level for 5 seconds to the EXT1 pin (before this command the signal is HIGH level)
<A>
<IO>1,1,0,1000
<Z>
