Introduction

Install Virtual COM Ports on PC

Step 1: From the Windows Start menu, run the Install Virtual COM Ports utility included with the VLINX software,

Step 2: Search for all servers on the network

Step 3: Select the first port (4000) and map it to an unused COM port (e.g. Port 15). Configure it for TCP protocol and the appropriate IP address (determined in the last section).

Figure 5. Configuring the Virtual COM Port

Check Communications

Step 1: From the Windows Start menu, run HyperTerminal

Step 2: Configure HyperTerminal to connect using the COM port configured in the last section (e.g. Port 15).

Step 3: Set Baud Rate, Data/Parity/Stop, and Flow Control to match the configuration of the serial device connected to the ESP904 serial port.

Step 4: Communications with the serial device should now be operational.
