3. Setup and Installation
3.1. Physical Installation
The HMI unit is designed for panel mounting. Ensure the installation environment meets the specified working temperature (0-45°C) and humidity (5-90% non-condensing) requirements.
- Cutout Size: Both TPC7012El and TPC7022Ei require a panel cutout of 192mm x 138mm.
- Panel Protection: The front panel is rated IP65, providing protection against dust and low-pressure water jets.


3.2. Wiring
Proper wiring is crucial for the safe and reliable operation of the HMI. Refer to the following guidelines and diagrams.
- Power Input: Both models require a 24V DC power supply (±20%). Connect the positive (+) and negative (-) terminals to the designated power interface on the rear panel.
- Serial Communication: The HMI supports RS232 and RS485 serial communication. Refer to the serial port definition for correct pin assignments.
- Ethernet (TPC7022Ei only): The TPC7022Ei model includes one 10/100M Ethernet port for network communication.
- USB Ports: Both models feature one USB Host port and one USB Slave port. The USB Slave port is used for program download.
3.2.1. Serial Port Definition (DB9)

| Interface | PIN | Pin Definition | Detail | Position |
