Need one Adam-4520I module for RS-485.
The test method is as follows
RS-232 U-boot setting：
RS-232（COM3）
GPIO
1. Short GPIO pin1(in) 151 & pin6(out) 141
# echo 150 > /sys/class/gpio/export # echo 141 > /sys/class/gpio/export # echo in > /sys/class/gpio/gpio1/direction # echo out > /sys/class/gpio/gpio2/direction # echo 1 > /sys/class/gpio/gpio2/value # cat /sys/class/gpio/gpio1/value 0 # cat /sys/class/gpio/gpio2/value 1
