For another model, check its cable, pin map, and development setup under MPAINO Series or MPINO Series. Do not reuse the I/O numbers below on another model without checking them.

1. Install the Windows Arduino IDE from the official Arduino download page.
2. Download and run ARDUINO SDK INSTALL from the ILOGICS Arduino SDK download page.
3. Close Arduino IDE and start it again. Follow the product section below to connect the cable and choose the board and port.

At the top left of Arduino IDE, Verify (✓) compiles the code and Upload (→) transfers it to the product on the selected port. The board and port selection screens are shown separately for each product below.

The ILOGICS SDK configures digital I/O directions automatically. These examples do not need a separate pinMode() call.

1. Check the power specification and R (relay) or T (transistor) output type on the product label. Disconnect output loads for the first upload.
2. Connect the PC to the CPU module's USB download port with a USB cable. USB power alone does not establish that field output loads can operate; check the product's main power supply requirements.
3. In Windows Device Manager → Ports (COM & LPT), note the COM number shown for Silicon Labs CP210x USB to UART Bridge(COMx). If it does not appear, install the CP210x USB driver and reconnect the cable.

Open Select other board and port… from the board selector at the top of Arduino IDE.

This program turns the first output, 64, on and off every 0.5 seconds.

const uint8_t OUTPUT_CHANNEL = 64;  // First MPAINO-8A8R(T) output
 
void setup() {}
 
void loop() {
  digitalWrite(OUTPUT_CHANNEL, HIGH);
  delay(500);
  digitalWrite(OUTPUT_CHANNEL, LOW);
  delay(500);
}

Open File → New Sketch, enter the code, and save it with Ctrl + S. Click Verify (✓) and check for Done compiling.; then click Upload (→). Check the output after upload. On an R model, you can hear the relay click. On a T model, switch off the power before connecting a test load according to the output wiring guide.

Output 64 turns on when the first input, 0, is HIGH.

const uint8_t INPUT_CHANNEL = 0;     // First MPAINO-8A8R(T) input
const uint8_t OUTPUT_CHANNEL = 64;
 
void setup() {}
 
void loop() {
  const bool inputOn = digitalRead(INPUT_CHANNEL);
  digitalWrite(OUTPUT_CHANNEL, inputOn);
}

Check the input terminal and COM wiring for 8A8R or 8A8T. Switch off power before connecting the input signal, then turn the input on and off and check that the output follows it.

1. Check the power specification and R (relay) or T (transistor) output type on the product label. Disconnect output loads before the first upload.
2. Connect the PC to the CPU module's USB download port with a USB cable. Before checking output operation, confirm the main power and output wiring for your product.
3. In Windows Device Manager → Ports (COM & LPT), note the COM number shown for Silicon Labs CP210x USB to UART Bridge(COMx). If no port appears, install the CP210x USB driver and reconnect the cable.

Open Select other board and port… at the top of Arduino IDE. The R and T models use the same board name.

void loop() {
  digitalWrite(OUTPUT_CHANNEL, HIGH);
  delay(500);
  digitalWrite(OUTPUT_CHANNEL, LOW);
  delay(500);
}

Open File → New Sketch, enter the code, and save with Ctrl + S. Check for Done compiling. after Verify (✓), then click Upload (→). On an R model, you can hear the relay click. For a T model, switch off the power before connecting a test load according to the output wiring guide.

Output 64 turns on when the first input, 0, is HIGH.

const uint8_t OUTPUT_CHANNEL = 64;
 
void setup() {}
 
void loop() {
  const bool inputOn = digitalRead(INPUT_CHANNEL);
  digitalWrite(OUTPUT_CHANNEL, inputOn);
}

Check the input 0 terminal and COM wiring for 16A16R or 16A16T. Switch off power before connecting the input signal. Then turn the input on and off and check that output 64 follows it.

1. Check the power specification and R (relay) or T (transistor) output type on the product label. Disconnect output loads for the first upload.
2. Connect the PC to the product's download port using the ILOGICS MP Download Cable. A regular USB cable or third-party USB-to-TTL cable cannot replace it.
3. In Windows Device Manager → Ports (COM & LPT), note the COM number for USB Serial Port(COMx). If it does not appear, install the FTDI USB driver and reconnect the cable.

Open Select other board and port… from the board selector at the top of Arduino IDE. The R and T models use the same board entry.

This program turns the first output, 32 (terminal P32), on and off every 0.5 seconds.
