This is an Arduino Mega-compatible CPU module. It is designed with a compact form factor so that it can be used practically in small spaces.

• This module must be positioned on the far left. Attach I/O modules to the right side.
• Up to 16 I/O modules can be connected to one CPU module.

• MCU: Mega2560
• Program memory: 256 KB
• SRAM memory: 8 KB
• EEPROM: 4 KB

• Power supply voltage: DC 12–24 V
• Power supply capacity selection: Use a power supply with enough capacity to handle the total current consumed by the connected I/O modules. If the total number of connected modules is 8 or fewer, a 24 V, 1 A SMPS is suitable. If the total number of connected modules is more than 8, use a 24 V, 3 A SMPS.
• Communication: RS232C x 2
• User program LED: 13 = LED

Apply a voltage between DC 12–24 V to the power supply terminals at the bottom of the terminal block.

- STATUS LED Blinking : This program blinks the STATUS LED.

const int StatusLED = 13;
void setup() {
    pinMode(StatusLED, OUTPUT);
}
void loop() {
    digitalWrite(StatusLED, HIGH);
    delay(1000);
    digitalWrite(StatusLED, LOW);
    delay(1000);
} 

- RS232 Communication : This is an echo communication program for channel 1 (Tx1, Rx1). Connect Tx1 and Rx1 to each other before running the program.

void setup() {
    Serial.begin(9600);
    Serial1.begin(9600);
}
void loop() {
 if (Serial1.available() > 0) {
     char rx_Byte = Serial1.read();
     Serial.print("I received: ");
     Serial.print(rx_Byte);
 
     Serial1.print(rx_Byte);
  }
}
