5.2 Input / 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.
