Trycom TRP-C08 USB to RS-232C Isolated Converter

Overview

The Trycom TRP-C08 delivers robust industrial-grade connectivity between a computer’s USB port and RS-232, RS-422, or RS-485 serial devices. It features 3000V DC isolation and internal surge protection on all data lines, shielding both the host system and converter from high-voltage spikes and ground potential differences. Designed for flexible deployment, the TRP-C08 supports DIN rail and panel mounting, making it suitable for field automation, data acquisition, and legacy serial device integration in harsh or electrically noisy environments.

Technical Features

Wiring Quick-Start / Pinouts

• RS-232 Terminal: TXD, RXD, RTS, CTS, GND
  

   1: TXD 2: RXD 3: CTS 4: RTS 5: GND 

  RTS and CTS should be shorted for RS-422/485 modes for stable operation.
• RS-485 Terminal: D+, D- (2-wire, half-duplex)
• RS-422 Terminal: TX+, TX-, RX+, RX- (4-wire, full-duplex)

Supported Protocols

• Auto direction flow control on RS-485
• Automatic detection of serial data format
• Fixed virtual COM port per USB plug

Sample Code (Windows, Python/pyserial):

 import serial ser = serial.Serial('COM3', 9600, timeout=1) ser.write(b'Hello\\r\\n') response = ser.readline() print(response) ser.close()
