Appendix A. Using Virtual COM

Virtual COM

is a software driver for Microsoft Windows operating system to convert the data in COM port

format to IP protocol format, and to transfer the data between the COM port on EW5302 device and the IP
network. As shown in Fig. 37, by creating Virtual COM ports on a PC, the PC can redirect the
communications from the Virtual COM ports over a TCP/IP network to a connection port of a EW5302 which
is also connected to a Serial device. By using Virtual COM ports, the application running on the PC can
send and receive data from the Serial device transparently over the TCP/IP network.

A.1. Pre-installation Requirements

Please check the operating system on your PC complied with the following requirements:

Processor: Intel-compatible, Pentium class

Operation system: Windows Server 2003, Window Vista, Windows XP, Windows 2000, Windows
NT 4.0 SP5 or later, Windows Me, Windows 98, Windows 95, Microsoft NT/2000 Terminal Server,
Citrix Meta Frame

Windows Installer 2.0

Network: Microsoft TCP/IP networking software

A.2. Limitation and Installation

Limitation

Virtual COM driver provides users to select up to 256 COM ports as Virtual COM ports using

SerialManager

Utility software. Users can select them from a list of COM ports, which is from COM1 up to

COM256.
