4. Functionality
The TRP-C37H functions as a network-enabled serial communication gateway. It allows traditional serial devices—such as PLCs, sensors, meters, barcode scanners, and controllers—to communicate over Ethernet networks. Each serial port can be independently configured as RS-232 or RS-485, enabling flexible integration with various equipment types.

Operating Modes:
- TCP Server Mode: The TRP-C37H listens for incoming TCP connections from remote clients, allowing multiple users to access serial devices over the network.
- TCP Client Mode: The device initiates a connection to a designated server, suitable for applications where the serial device must push data to a central system.
- UDP Mode: Enables broadcast or point-to-point communication for low-latency data transmission.
- Virtual COM Mode: Through driver software, remote serial ports appear as local COM ports on a PC, ensuring compatibility with legacy applications.

Applications:
- Industrial automation and process control
- Building management systems (BMS)
- Energy monitoring and smart grid integration
- Remote data acquisition and telemetry
- Access control and security systems
- Laboratory instrumentation and test equipment networking

Compatibility:
Compatible with Windows, Linux, and other operating systems supporting TCP/IP communication. Works with Trycom’s configuration utilities and third-party network management tools.
