Yaesu FT-8100 and R1-2023 is not triggering PTT

Hi,

I am not sure if it is an R1 issue or ASL3 issue, however on my node which connected as half duplex to Yaesu FT-8100 using R1-2023, PTT is not getting triggered even though status shows up as Keyed and R1 tx light turns on. I am able to copy my voice on other nodes perfectly but do not receive anything on my handheld from the node radio (except for a brief click).

I looked into PTT setting which is set to ground, I also explored usbradio.conf but couldn't get it to work either and it behaved in a similar fashion.

I read on R1-2020 and YAESU FT-7800 - App_rpt-users - AllStarLink Discussion Groups something related to 1200bps for data line but couldn't find the setting in the radio for it. I do not have the CPS.

Manual for FT-8100 shows data pin connections for 9600bps and 1200bps, so if it is a physical connection and that is the solution, I can swap the wires between those 2 pins. Manual link is provided and data pin connections are on page 21
Data Jack Pin Connections - Yaesu FT-8100R User Manual [Page 21] | ManualsLib

If anyone has had any experience with this please do let me know.

I am not familure with the R! but I would say check the 'input to the device and see if you are getting expected.
If inverted, you can invert the logic in the simpleusb/usbradio config file.

But as you are talking about data connection, what exactly is the purpose of this rig on ASL
Is it a freq agile remote base ?
You really do not need a data connection unless for that purpose.

In the manual it tells you how to turn on the 9600 baud data rate. also you might want inverted for receive with CTCSS set to off in the simpleusb.

Thanks @Mike and @N8PC Brad for the response.

I have selected carrierfrom = usbinvert and CTCSS is set off in simpleusb.conf. When carrier is not inverted it starts txing spuriously. I am operating it as a half-duplex node.

R1-2023 is the URI that I am using to connect the radio to node PC. I have had it successfully connect using the relevant cables to Motorola GM338. To connect FT-8100 to it, I am using the specific cable thta plugs into the URI and the radios port. R1-2023 image

RX is great, as in when I tx on my handheld, the node radio FT-8100 receives the audio and sends it across very clearly to all connected nodes.

The issue is that audio originated at the other end does not get out of the URI to the node radio. I have tested that the URI is working by swapping node radio with another GM338 and that works as expected.

The 9600/1200 is a guess and I was hoping maybe someone who understands this might be able to shed a light on whether it is relevant in my case. The manual tells us about the baud rate but that is in relation to a Terminal Node Controller (TNC).

What else could I possibly check or where should I probe my multimeter prongs in to get useful information.

Could you better explain this.
As written, it says to me the the TXr is outputting stray signals, which by themselves can be parasitic and collecting on your wires.
Perhaps you meant sporadically

The data connection is not used or required by ASL 'UNLESS' you are setting up a frequency agile remote base and would use the serial port for tuning.
(CAT commands)
Either way, I would not connect them until you have audio and logic correct.

You need to verify logic of cos and ptt.
check the lines while disconnect from the URI to see what is actually used by the radio,
then adjust per software settings in documentation.
You say you are using a R1 URI,
It should have provided some documentation on proper set-up of it's logic to radio.
And stated the logic output for the USB interface.
Once you know that, you can adjust the parameters in ASL to match.
Is there documentation on the web ?

Just as not all radio's are not the same, Not all URI's are the same. It is not plug and play.

Thank you! I will check each pin to see whats up with it and share here.

R1 documentation has provided instructions and I have implemented them accordingly however it is possible that this yaesu model is not the same as other models and possibly uses different pin configuration.

As for the data connection, it is basically using the data port for connecting URI and radio and as you said it, it might not necessarily be using the data pin but just the gnd, cos, ptt pins for operation without having to connect a direct line into the pcb. There is just 1 port on the back of the radio.

The "sporadic" (TU) tx happens only when usbinvert is changed to usb.

Thanks again! I'll post my findings as soon as I am done testing.
