• RS-232 Loopback Test (eg. COMA: ttyLP0):

Step 1:. Connect loopback with COMA(ttyLP4)&COMB(ttyLP5)
Step 2: Run test command.

RS-485

RS-485 Test:

Step 1: Test RS-485 with Adam-4520. Connect Adam-4520 with COMA with DB9 as the following(COMA(ttyLP4)&COMB(ttyLP5))

Adam-4520 RX- <-->ROM-2820 COMA DB9 Pin  1,

Adam-4520 TX+ <--> ROM-2820 COMB DB9 Pin  2

Step 3: Run below command:

Step 2 :Create the following file and save it as rs485.sh

#!/bin/sh

i2cset -y -f 4 0x21 0x00 0x10
i2cset -y -f 4 0x21 0x01 0x01
i2cset -y -f 4 0x21 0x02 0xdf
i2cset -y -f 4 0x21 0x03 0xfd
i2cset -y -f 4 0x21 0x04 0x00
i2cset -y -f 4 0x21 0x05 0x00

i2cset -y -f 4 0x21 0x07 0xfc

Step 3: Run below command:

# sudo chmod 775 rs485.sh
# ./rs485.sh
# stty -F /dev/ttyLP4 -echo -onlcr 115200
# cat /dev/ttyLP4 &
# echo "Serial Port Test" > /dev/ttyLP4

Step 4: You need to open two terminals: one to connect to the debug port of the ROM2820, and the other to connect to the Adam-4520.

Step 5:You can send data from the ROM2820's debug port to the Adam-4520, and you can also input text from the Adam-4520's terminal using the keyboard so that the ROM2820's debug port can receive it.
