I’m at a loss... looking for ideas on how to proceed...
Still attempting to get our repeater working... rebuilt the computer that
crashed, and it works well... Getting strange results when connecting the URI
back to the radio (can’t find anything wrong there). The fact I can’t
seem to get a URI, or URIx working with my computer suggests a possible issue
with my setup. I have some inputs from
folks for changes in the usbradio, or simpleusb which I’d like to check,
but need to confirm the URI is working correctly, so I’m not chasing
hardware issues by looking at software.
I tested my URI using the loopback diagram and uridiag; it
passes all the digital, and fails all the analog. I procured a URIx for
replacement, and built up the loopback connector for it and tested, same
results. I’ve checked and rechecked my wiring of the loopback connector. The
URIx uses two 1k resistors and two extra jumpers than the URI (see below), and
the URI two 10k resistors per DMK folks. (There is a confirmed error in the
uridiag listed connections). I did not connect the URIx 12 and 20 (Blk and Wht)
leads, nor the power supply to activate the 2x amplifier (pins 13 & 25),
which I am not using. I’m told the correct connections are as shown below
from the URI-FAQ.pdf, with change of 1K for 10K for URIx per DMK, and comparing
with the URIx test fixture.
Assuming the URIx was good from the factory, and all I did
was
connect it up to the loopback and computer,
turn on the computer with ACID
