Putty is a popular open source terminal program. You may already have a copy of this program on their PC, if not, it can be downloaded at:

Or search for "putty" in Google and click on the second link. Then click on "Download it here", then chose the proper version for your PC.

Using the serial port

To setup PuTTY using a serial port, you must have a USB to Serial port, straight through, cable. The switch has a female RS-232 connector, the USB cable connector must have male pins.

When the USB cable is plugged in, windows will assign a COM port. The using Window's Device Manager, determine the com port of the USB cable. It's usually between COM3 and COM6, but can be any number Window's chooses to use.

The baud rate is: 19200

To setup PuTTY, select the "Serial" connection type, then enter the COM port, and set the baudrate:

After setting up the com port and baudrate click on "Terminal" jump forward to: "Setting up the line control options"...

Using TCP/IP

To setup PuTTY using TCP/IP you will need to search the network for the IP address of the switch. The switch's MAC address will be listed under Zektor or Pulse-Eight, depending upon when the switch was made (please refer to this support solution if unsure)

The MAC address will begin with either: 5C.D4.AB.xx.xx.xx or 00-15-82-xx-xx-xx

Once the IP address is known setup a "Raw" connection using port number 50005, this example assumes the IP address was found at

After entering the IP address and port number click on "Terminal".

Setting up the line control options

After setting up the serial port or TCP/IP port, click on "Terminal" in the Category window to setup the line discipline options. Set them to "Force on" this allows you to see what you are typing, and to edit it before sending:

After the two options are selected, press the "open" button, and command window should open up.

To test whether a connection has been made, send the version command: 

  • ^V$

and then press enter, you should see something similar to this, with a string indicating which model switch you have:
