Peter, My records show that you purchased the original Y-BOX v1.3, which requires an Elecraft AUX cable from Y-BOX to amp. (The Y-BOX v2.x and v3.0 Y-BOXs allow any DE-15 M/F non-VGA cable to be used instead of the Elecraft AUX cable).
The easiest solution, if your electrician can snake a cable with the molded DE15 connectors through the wall, is to insert a 25' M/F 15-pin extension cable like this one *in series with your AMP AUX cable*. https://cablesondemand.com/15-pin-hd-d-sub-cable-hd15/15-pin-hd15-deluxe-hd-d-sub-cable-copper-shielded-male-female-cs-dsdhd15mf0-025 This will achieve the proper electrical connections, though at 31' total length you may be at the limit of the maximum AUX cable length that will work reliably. Another option is to have your Electrician wire a pair of SHIELDED "Ethernet" CAT6 (8-wire) outlets between shack and basement, with RJ-45 jacks mounted to the wall. Wiring two pairs of outlets at each end will allow both Elecraft AUX *and *Ethernet connections to the amp from upstairs, providing a good connection for the KPA1500 Remote software running on a PC upstairs. But, KPA1500 firmware updates (rare these days) will still require a direct USB connection to the amp. If using RJ-45 jacks (something Electricians regularly install), I can make you a custom DE15M to RJ45 shielded cable to reach from Y-BOX to the wall jack, and a second RJ45 to DE15F cable from basement wall jack to the AMP AUX. Only 8 pins out of the 15 will be connected, but that will be sufficient. I could theoretically make a USB to RJ45 cable that would allow USB connection to the amp. for firmware updates, but the theoretical maximum length if USB 2.0 is about 15', so that may not work well at all. 73, Bob, N6TV https://bit.ly/Y-BOX On Thu, Jun 2, 2022 at 8:11 AM <li...@w2irt.net> wrote: > I need to move my KPA-1500 into the basement, and I've got an electrician > coming to put in the new outlet next week.
