Powering the WiSnap unit will print out a few boot messages to the terminal (if configured properly).

Configure the port for 9600 baud, 8 data bits, 1 stop bit, no parity, and no flow control. Once connected, launch your Terminal program, such as JavaTerm, PuTTY, TeraTerm, or HyperTerminal.

Tcp redirector serial#

You can configure WiSnap settings with the RS-232 interface to an open serial port on your PC, or by using an USB-to-Serial adapter. NOTE: This should happen twice since two COM ports are being installed.

Allow Windows to search and install the software drivers automatically. The screen is shown below and to the right asks if you would like to install shortcuts in the Start Menu and if you would like to add a default pair of COM ports during installation.Īfterward, Windows may bring up the “Found New Hardware Wizard.” This is because the virtual COM ports were detected. Click “Next >” through the dialog screens and agree to the license to complete the installation. Running the “setup.exe” begins installation as a standard wizard. All data sent from the “A” port will be mirrored on the “B” port of the same pair, and vice-versa. These names can be changed, but the default convention begins with “CNC,” followed by the A-B pairing, and the final digit at the end represents the number of the pair. The COM port pairs will be given names starting at CNCA0 and CNCB0. You can create as many pairs of virtual COM port as you like, and use any pair to connect one application to another. You can download the com0com installer HERE.

Tcp redirector driver#

The first step is to install the Null-modem emulator (com0com) application, which installs and works as a driver for a pair (or many pairs) of virtual COM ports.
