5.2Input / Output port
This port can be configured as either an input one or an output one.
To configure it as an input port, first issue AT+WIOW=2, 0 to disable the output port. Use AT+WIOR=3(Fargo
Maestro 100) or AT+WIOR=1(Fargo Maestro 20) to read the status of this input port. Response +WIOR: 0
represent Logic HIGH (>3V); Response +WIOR: 1 represent Logic LOW (<0.5V) To use it as an output port, issue
AT+WIOW=2,1 will turn it on and it will drain current to ground. The current is recommended not to exceed 10 mA.
Issue AT+WIOW=2,0 will turn it off.
5.3 RS232 AUTO-ONLINE mode (power saving)
When being in the AUTO-ONLINE, the RS232 transceiver will shutdown most of its hardware to save power if it
does not detect a valid input for more than 100uS. The RS232 transceiver will wake up when valid input is detected
again.
By default, the RS232 transceiver is put in AUTO-ONLINE. This mode can be turned off by issuing AT+WIOW=4,1.
