Has anyone made the combination in the subject line work?
I am getting a com port for the Silicon Lab chip. I have USB audio codec.
The ACC1 plug does not seem to fit well in the ACC (1) jack. Does not seem
to go in far enough. Should I trim off some of the plastic cover?
The remote plug is in the Remote CI-V jack.
I have tried RTS, DTR, and “RTS” and “DTR” on the com port (17) in the Direwolf setup.
I ordered the Digirig for an Icom so it should have the CI-V setup. I did not check.
I can’t find anything in the Icom manual that tells me the ACC-1 is active in FM on VHF.
I am getting audio in on the Direwolf screen.
Both audio RX and TX levels are set at 35 in Windows 10. (mid point of the recommended levels). so the audio setting must be OK in Direwolf.
Direwolf continues to say the PTT is not configured for channel 0.
My configuration for channel 0 is “PTT COM17 RTS”
Rig and com port 17 are both set to 9600 bd.
I presume I have to connect PinPoint to network KISS mode for Direwolf
and check the connect TNC automatically box. The network KISS settings are default.
This setup refuses to transmit.
What simple thing am I missing?
the IC-746 has separate ptt lines for hf and vhf (the audio is single sourced)
in your manual they will be labeled HSEND and VSEND
(i don’t have a 746 anymore so i can’t lookup the acc1 pinout)
if they are both located on the acc1, you can modify the din plug and tie them together. if vsend is on acc2, then you’ll need to run a wire from that pin to the hsend.
looks like a 7 pin din plug with the hsend and vsend lines connected would do the trick.
(the hsend line on acc2 will be ‘at ground’ when the hsend line on acc1 is ‘at ground’ so you don’t have to tie the two acc plugs together, just tie the hsend/vsend together at acc2)
as best as i can remember, the IC-746 didn’t have ptt via ci-v, or if it did, it wasn’t band selective.
i had one as a remote base on my 6m/70cm repeater and while it was CI-V controlled, the ptt source was traditional grounded pin. hsend and vsend lines tied together.
like your settings above
com# RTS (this is connected to the AUDIO/PTT cable of the digirig. no effect on the remote control cable of the digirig)
(dtr is not connected to the digirig cable so won’t have any effect)
if you CAN PTT via ci-v, tying the hsend and vsend lines of acc2 will achieve the same result.
when the radio is in TX via ci-v/acc port, the hsend line is grounded, the vsend will be grounded as well and the radio will TX while parked on 2M.
lastly, if you are able to ptt via ci-v, you will remove the ‘RTS’ from the ptt method entries. i don’t know the direwolf syntax but you would replace RTS with CI-V in order to send ptt command via ci-v
OK, I really don’t know what the CI-V cable does.
It is not well explained as far as I can find now.
All I know is Digirig says to use their cable set with the IC-746pro and I can’t make it work.
I am reading 4 manuals to try to get some kind of insight as to what I am missing.
Digirig manual, IC-746Pro manual, Direwolf manual, and the PinPoint manual as well
as many online suggestions and videos; all with no joy.
I am curious why Digirig didn’t just use the 6 pin mini din data port.
The hardware PTT line in ACC(1) used by the Digirig via RTS signal is for HF/50MHz only. Here is the relevant fragment from the transceiver’s documentation:
