TTL/CMOS RS-232 Receiver Output. For the MAX3130, drive
IRMODE
low to connect
R2OUT to the IR receiver output, and drive
IRMODE
high to connect R2OUT to the
RS-232 receiver output. For the MAX3131, R2OUT is always internally connected to the
RS-232 receiver output.

IR Mode Control. Drive
IRMODE
low to connect R2OUT to the IR receiver output and
T2IN to the IR transmitter input. Driving
IRMODE
low also shuts down the RS-232
charge pump and puts the RS-232 transmitter outputs in a high-impedance state. Drive
IRMODE
high to connect R2OUT to the RS-232 receiver output and connect T2IN to the
RS-232 transmitter input.
