Need one Adam-4520I module for RS-485.

The test method is as follows

RS-232 U-boot setting：

RS-232（COM3）

GPIO-for example

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
