Good afternoon, I have a K2 that refuses to talk to my computer. The computer software works and talks to my K3s and an RT21 rotator controller using a straight USB cables.
The K2 has a serial port and requires the KUSB cable which plugs into the USB port and terminates in a DB-9 connector. It is warm, so I assume there is a chip in there, doing what is required to convert USB to serial. The KUSB cable is recognized when connected to the USB. Voltage check at pins 5,3,2,and 1 per the KIO2 manual are good. All looks like it would work, but it doesn't. To continue troubleshooting, I would like to have information that gives me voltage readings at the pins on the KUSB cable without the K2 connected. A further help would be to have a way to watch the TXD and RXD data. The software attempts to connect to the K2 several times before giving up, It would be nice to have a schematic of the KUSB cable. If anyone has experience troubleshooting this sort of thing or knows where to get more information, please let me know. Any help would be appreciated. 73, Dave, K4TO ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
