Hi Joe, Thank you for taking the time to explain so thoroughly! I now understand the connections involved, and the options.
I think I need the RS-232 version, and the passive splitter you mentioned. I have a P3, and a Computer connected, so I have no serial ports remaining. I could split at the back of the P3, and put the keypad on there... -- Thanks and 73's, For equipment, and software setups and reviews see: www.nk7z.net for MixW support see; http://groups.yahoo.com/neo/groups/mixw/info for Dopplergram information see: http://groups.yahoo.com/neo/groups/dopplergram/info for MM-SSTV see: http://groups.yahoo.com/neo/groups/MM-SSTV/info On Fri, 2015-02-20 at 15:19 -0500, Joe Subich, W4TV wrote: > Genovation (www.genovation.com) has several programmable keypads in > three broad categories: > > A) the USB HID series that becomes a Windows or Mac keyboard > recognized by the operating system.
