[Elecraft] W2 and use with computer

[Brian & Cyndi]

Hi, Doug!

The W2 acts exactly as described in the manual.  Send it a "F" and it 
responds with Forward Power.  Our belief that the wattmeter should not 
speak unless spoken to goes back to the W1 and Wayne Burdick's 
philosophy of how electronic equipment should behave.

To do this I plan to run the serial line from the W2 thru the Com1 transparent serial channel in a pair of RemoteRig RRC-1258MkIIs units.  The computer at the control site will be running the W2 Ver 1.1.9.6 software.  (There is no computer at the remote site where the K3&  KPA500 are located.)  Momentary switch closures to turn the K3 and KPA-500 ON will be provided by the remote switch capability of the MicroBit 1216H Web switch units.  Confirmation of the K3 being ON is provided by receive audio, but I need a power sensor to confirm that the KPA-500 has been turned ON and is actually transmitting.

What got me concerned is the explanation in the top paragraph of the Elecraft W2 Serial Interface Commands document Rev D.  It says in part "The W2 responds to commands for data supplied by the external system.  Nothing is sent until a command is received by the W2."
