R30 Icom receiver CI-V to repeater controller...R30 baud rate..

[WX5812]

I have a ham repeater w/controller that will control a CI-V radio. I am wanting a receiver to put on one of the ports to be able to steer to 900/1.2ghz repeaters. Also HF receive would be nice as well. I would like to get a R30 but I need to baud rate to be 1200 (that's what the controller manual says to set rate at) I believe the baud rate on the R30 only goes down to 4800 or 9600...I can use an R6 but there is no SSB,.. An R20 would be ok if I could find one. Has anyone put a receiver on there repeater like I am describing?
Also is there a work around to reduce the baud rate to 1200 on the R30?

You might want to look at the ICOM PCR-1000 or the less capable PCR-100. Check the baud rate in the manuals at ICOM-USA

EDIT: The PCR-1000 recommends 38,400 Bps or better, probably due to bandscope updates. But there is no setting in the radio, so probably it auto ranges the baud rate.

I would look into the possibility that the UART in the repeater controller has jumpers and crystal that can be changed to bump up the baud rate. Probably it was designed within the Hayes Modem era.

I will look into the controller and see about that. Thanks for the reply on that

Unfortunately, the PCR1000 does not support the CI-V protocol. Icom created a whole new control protocol for the PCR series.
Does it have to be a handled radio?
I would suggest trying an R8500 which does support CI-V, but I can't tell from the manual if it goes down the 1200 baud.
I will try to check on the radio later today to see if you can select 1200 baud.
The older R7100 does support 1200 buad for the CI-V interface...

No it does not, I know the all of the base receivers will work… except for the r8600, I’m not sure if that one will do 1200 or not. I’m sure it will… but that’s starting to get into the $$$$ pretty deep. The R30 is pretty high for a handheld but if it would do 1200 then I would have my problem solved. The used market is there but not too many flying around. I’ve posted wanted ads and trade ads but no luck as of yet.

Baud Rate Converter
This seems to be a rare device. is 1200 baud a rate it accepts? It has a buffer of 16 kB.

Oh my, they aren’t playing lol. It would be nice if I could just get an Arduino to do it somehow. I have tons of those

It all seems all so very basic. Your repeater controller is probably only sending CI-V to change frequencies. I wonder if it needs a response at all?

The Industrial automation companies probably deal with this because they are not about to phase out a million dollar machine because the baud rate is fixed.

 

[WX5812]

That is very true because that is all it is doing. I’m trying to think of what the radio will transmit to the controller and nothing comes to mind. I can see if it was going to read s meter or anything like that but it’s not

 

[bagmouse7]

I just checked my R8500 and it will do 1200 baud CI-V.
It actually goes all the way down to 300 baud.
I suspect any of the older Icom receivers will also support 1200 baud.

You don't even need RS232 level conversion as all of CI-V is 5V TTL. You might need a level conversion chip or transistor for 5V to 3.3V for arduino or such. Read, Buffer and blast.

There you go!

Since it’s only giving the receiver commands from the controller I may try the R 30 and see if it’ll work. Since the controller doesn’t need anything back from the radio. I’ve looked at all the manuals of the other receivers and I know they all do it except for the handhelds r2 and r5 I believe. The ID 5100 and ID 4100 also do this but they only go down to 4800 but like we were talking earlier they might all possibly
work as well Since they are only taking commands

Can you explain that a little deeper because I thought I didn’t need a TTL converter Between radio and controller

You probably dont.
You have not said what repeater controller you have, so I assume it has 5 volt TTL output for the CI-V. CI-V only needs a RS232 to TTL converter when a PC or other RS-232 device controls it.

If you use, say an Arduino, it may have 3.3 V referenced TTL. in that case there are simple level converters to correct that.

It won't hurt to try, especially in auto mode.

Sorry about that it is a RLC Club Deluxe II

The manual I found online, chapter 15 describes HF radio connection, 1200 baud for ICOM, 4800 baud for some other makes. Also the RLC outputs at RS-232 so you WILL need an RS-232 to TTL convertor..

You might be a bit to fool the hardware into operating at 4800 baud by transposing the 1200 and 4800 selection with a mod. This assumes the UART is not integrated in the CPU . EDIT: Which unfortunately it looks like it is integrated into the CPU. So no wiring hack..

You might want to seek an RLC user group to see if anyone has programmed one to operate 4800 baud CI-V with ICOM radios.

I have a rs232 to ttl converter.. I made a few of them a while back to controll a M710 via my computer. It worked quite well… I was at a big hamfest this weekend and was able to pick up a R7000 and 706mkiig for a steal! So with these I can do what I need to do… the r7000 is pretty off frequency so I’m going to have to do a complete alignment with my spectrum analyzer /w tracking gen and hope for the best… the service manual gives a pretty good step by step instructions… the ssb rx also sounds sooo tinny it’s rediclous. I would imagine someone put a screw driver in it before, but for $60 I won’t complain too much.
But for the heck of it I will ask about 4800 baud on the rlc group… worse comes to worse I will set the 706mkiig to 4800 and see if the controller does anything to it.
