# cat /dev/ttyLP4 &

# echo "Serial Port Test" > /dev/ttyLP4

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 RX+ <-->ROM-2820 COMA DB9 Pin 2,
Adam-4520 TX- <-->ROM-2820 COMB DB9 Pin 1,
Adam-4520 TX+ <--> ROM-2820 COMB DB9 Pin 2

# stty -F /dev/ttyLP0 speed 115200 ignbrk -brkint -icrnl -imaxbel -opost -onlcr -isig -icanon -iexten -echo -echoe -echok -echoctl -echoke
# cat /dev/ttyLP0 &
# echo "Serial Test" > /dev/ttyLP0

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

<span lang="EN-US" style="font-size:10.0pt">#!/bin/sh</span>
<span lang="EN-US" style="font-size:10.0pt">i2cset -y -f 4 0x21 0x00 0x10</span>
<span lang="EN-US" style="font-size:10.0pt">i2cset -y -f 4 0x21 0x01 0x01</span>

<span lang="EN-US" style="font-size:10.0pt">i2cset -y -f 4 0x21 0x04 0x00</span>
<span lang="EN-US" style="font-size:10.0pt">i2cset -y -f 4 0x21 0x05 0x00</span>
<span lang="EN-US" style="font-size:10.0pt">i2cset -y -f 4 0x21 0x06 0xcf</span>
<span lang="EN-US" style="font-size:10.0pt">i2cset -y -f 4 0x21 0x07 0xfc</span>

Step 3: Run below command:

<span lang="EN-US" style="font-size:10.0pt"># sudo chmod 775 rs485.sh</span>
<span lang="EN-US" style="font-size:10.0pt">#</span><span lang="EN-US" style="font-size:10.0pt"> ./rs485.sh</span>
<span lang="EN-US" style="font-size:10.0pt">#</span><span lang="EN-US" style="font-size:10.0pt"> stty -F /dev/ttyLP4 -echo -onlcr 115200</span>
<span lang="EN-US" style="font-size:10.0pt">#</span><span lang="EN-US" style="font-size:10.0pt"> cat /dev/ttyLP4 &</span>
<span lang="EN-US" style="font-size:10.0pt">#</span><span lang="EN-US" style="font-size:10.0pt"> echo "Serial Port Test" > /dev/ttyLP4</span>

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.
