Re: [Elecraft] Digital Display Unit for the Elecraft KPA500
Keith Ennis (KV5J) is proud to introduce the second in his line of Digital Display Units.The Digital Display Unit for Elecraft's KPA500. For the Elecraft KPA500 I have designed a compact, easy to read Digital Display Unit (DDU). It allows the monitoring of 5 crucial readings all at the same time. 1. Power amplifier's heat sink temperature2. Power amplifier's high voltage voltage3. Power amplifier's current4. Power amplifier's output power5. SWR that the KPA500 sees at its output The DDU measures is size only 4x4x2 inches with an easy to read 2 line display that can be located at the operating position and the KPA500 can be located over 10 feet away. The DDU is designed with the following features: Easy to read 2 line displayNo USB or serial cable to computerNo com port in Windows to manageNo computer neededPlug and PlaySimply connect the supplied DC power cable to the power supply and the supplied data jumper cable to the KPA500Retains all functions of the KPA500 front panelAll displayed info obtained directly from the KPA500 The DDU will poll the KPA500 and display PA voltage and PA temperature during both receive and transmit cycles. It will add watts and SWR display for a short amount of time after unkeying the amp.

Re: [Elecraft] Digital Display Unit for the Elecraft KPA500
I purchased it exactly for those reasons; my KPA500 is on a shelf under my operating desk. The DDU will enable me to see what I can't easily see now. Perfect solution. And yes, my DDU arrived today and I will soon give it a shakedown cruise...

[Elecraft] Digital Display Unit for the Elecraft KPA500
Andy, It's design was not to replace the KPA500 utility if that is what you want to use. It was designed to show the 5 most often used readings from the front panel that can only be seen one at a time. Plus it does not use any PC resources. Monitor space is limited to most operators. Same with com ports. Place the KPA500 wherever you want and place the DDU next to your radio. Saves on heat, noise and desktop space. Thanks for your input.73 Keith,KV5J __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
[Elecraft] Digital Display Unit for the Elecraft KPA500
"It would be handy if it repeated the rs232 so you could leave the computer hooked up for the utility." I doubt any design change would be required. The display device would simply have its TX line disconnected and it would listen to KPA500 responses to utility polling. In my system that's done with a multiplexing relay so it can be used with or without the utility with no cable re-configuration. In my opinion the parameters that are useful when monitoring a KPA500 are PA dissipation and PA efficiency. This device displays neither.
