My long-suffering T2-135 may have bit the dust. Can anyone give me a read on this?
It's installed in the Alinco radio, set to the APRS channel with the modem enabled (remember, it's been working in this configuration for over 18 mos). As soon as the radio is powered, the red and green LEDs blink successively, then the red LED turns on steadily. The radio is receiving packets (you hear the "click" if the volume is turned up), but there is no status change on the LEDs like there used to be, and no KISS data is output (I had it in KISS mode on Port A). It will not connect to OTWINCFG.EXE, either with the "Load Firmware" box checked or not. I know it isn't the serial port or cable, because I can use a terminal emulator, short pins 2 & 3, and type and get characters echoed. I know it's not the connector polarity, because I tried a null modem, too, to no avail. It seems like the processor must be running to blink those LEDs, but can anybody think why the T2-135 won't respond in any other way? Thanks & 73, Steve Bragg KA9MVA The HamHUD guy
