Elecraft W2 Serial Interface Commands

Revision D, April 12, 2010. Applies to firmware rev 1.00 or higher.

The W2 responds to commands for data supplied by the external system. Nothing is sent until a command is received by the

W2. These requests are in the form of a single letter as shown below. The user sends a single character and receives one data

string in response. The semicolon (;) is an end-of-string identifier, and will be at the end of every return string. The strings vary

in length. Use the table below to determine the output from your command input.
