Wigman Posted March 7 Posted March 7 Just finished installing a 400v ac compressor. I already use Putty for another controller so I have the program already. I plugged in the usb and shows up as com10 in device manager I tried opening putty with the parameters in the manual and tried to flash a software update and enter putty through the update. The software update gave a connectivity error message in the DOS screen and putty gives a blank screen i continuity tested the wiring at the end of the headphone jack. Two wires go to the middle pin, one to another pin, one to ground. All of the different shaft separations on the plug have mega ohms between them. when I plug in the usb cable it flashes an led and then goes off. It stays connected in the device manager. Is there a diagram for the end of the headphone jack cable to make sure the wires and going to where they should be? what else can I check?
Wigman Posted March 7 Author Posted March 7 I’ll add that I tested 12v constant and ignition and ground at the connector pins and they all check out.
Wigman Posted March 8 Author Posted March 8 I tested the end of the Jack. tip- no continuity sleeve 1- green and orange continuity sleeve 3- yellow continuity and black but only in some positions sleeve 4- black continuity and yellow but only in some positions. When the harness cover is threaded on there is no continuity between sleeves. when plugged in there is 3.3v between sleeve 4 and 2 and sleeve 4 and 3. Is this correct?
Wigman Posted March 8 Author Posted March 8 I got it working after putting the jack end back together. i think a connection was grounding out previously. Now it connects.
