9. Application 

The TRP-C31S allows serial devices to communicate over a LAN or Intranet network. Serial 

devices are no longer limited to a physical connection to the PC COM port. They can be installed 

anywhere on the LAN using TCP/IP or UDP/IP communications. This will also allow traditional 

PC COM ports access to a serial device anywhere on the LAN network.     

   

9-1 Direct IP Mod

e  

Direct IP connections allow applications using TCP/IP or UDP/IP network socket programs to 

communicate with the asynchronous serial port on the TRP-C31S. In this type of application the 

TRP-C31S is configured to TCP or UDP server. The socket program running on the PC 

establishes a communication connection with the TRP-C31S. The raw data is sent directly to and 

from the serial port

.  

 

9-1 Virtual COM Mode 

 

The Virtual COM mode requires the installation of a driver. When installed a new COM port is 

added to the Device Manager. Windows programs using standard Windows API calls will be able 

to interface with Virtual ports. The PC will act as the host connecting to the TRP-C31S when the 

program opens the virtual COM port.   

 

   

Once the connection is made, the LAN is transparent to the serial device. Applications work just 

as if the serial device is connected a host’s physical COM port. The virtual COM port converts the 

application’s data into IP packet destined for the TRP-C31S, which in turn converts the IP packet 

back to serial data.     

   

In this mode, theTRP-C31S must be set to either TCP/server or UDP/server in the menu with a 

designated communication port number. The virtual COM driver is a TCP or UDP client.     

 

   

9-3 Paired Mode     

Paired mode is also called serial tunneling. When this type of configuration is selected additional 

software will not have to be loaded on a host PC. In fact a PC is not required to make the 

connection. Any two dumb serial devices that can communicate with each other through a serial
