090: Read Whether Input Line is High or Low
This command allows you to read the input lines. If they are not hooked up they will read high
(they have internal pullups).
<090> L Read single input line
<090> L..L Read multiple input lines
Parameters:
- 090 is the default command name.
- L is the input line number (1..3)
091: Fire Input Line High or Low Event Trigger
This command is similar to Command 090. The difference is that instead of sending CW "H" or
"L", the high or low event trigger for that input line will be fired, which may be configured to
execute a macro or command (see Chapter 20). This allows you to program custom messages such
as "door open" and "door shut". Command 045 must be used to assign macros to the event triggers
for the input lines before this command will have any effect.
<091> L Fire input line trigger for input line L
<091> L..L Fire input line triggers for multiple input lines
Parameters:
- 091 is the default command name.
- L is the input line number (1..8) or a list of input lines (L..L)
Notes:
Multiple input lines can be processed with one call to this command by entering more than
one port number.
