I didn't know the NANO app could be run on a PC. I'm also interested to hear about a NANO USB cable.  What is it and how does it help you TX?

If you mean RRC-Micro forget everything I said.

Hi Steve,

I have had success in trouble shooting CAT issues by using a comport monitor. I don't know exactly what your setup looks like but if you can monitor the destination you should be able to determine if it really is RRC that is to blame.

Hi Buddy,

I agree with Palle. I understand that the beeps come from the control end.  I would follow Palle's advice and disable SIP ALG and move away from port 5060. It wouldn't hurt to move the rig RRC into the DMZ for testing simply to prove everything else is ok.

DJ0QN posts here quite a bit and has a comprehensive checklist that has helped many folks get their remote systems running. Do a search for his post and find his email address. He will send you a copy.

Hi Buddy,

You haven't given us much to go on. I will guess that when you are on your internal network your contro RRCl is pointing to a 192.168.x address for the radio. Once you get onto your wifi network that 192 address is probably not be reachable. In your control RRC you have to make sure the destination is the address in "Own Host Name" in the Dynamic DNS settings of tour radio RRC.

For your radio RRC, Static IP is OK and keeping it out of the DMZ is OK as long as your forwarding rules work.

I'm sure you've done a lot of work on this problem.

It is unclear from your PDF exactly how the PC sees the comport mappings. I don't think in every case that the RRC ports go in sequence against the PC port numbering. This is what mine looks like.

RRC1258 COM0 (COM16)
RRC1258 COM1 (COM13)
RRC1258 COM2 (COM6)
RRC1258 COMExtra (COM14)

Is it sure that you have your Com Port mappings correct?

On the last page of your PDF you show "Use USB as Com Port" is set to off in RRC-Control. Is this intended? I don't understand how anything could work from your PC if these are off.

Perhaps we didn't understand each other? I meant that perhaps the RRC could not see your phone wifi hotspots (basestation) because they are on 5GHz?

I believe the RRC WiFi only responds to 2.4GHz signals. Many modern laptops are now 2.4GHz/5GHz capable. Can this be the case for you?

Hi Bill,

I think all your questions are answered here. From what I can see, it is a one of five selector and the unused outputs are grounded.

I wired the remote RRC on a separate supply today (12V marine battery) and I get three dual tone beeps on the control RRC and the remote will apparently not power up. It had a power light.

Strange. If all you did was disconnect the RRC power and install the battery then the system should still power up. Something wrong there. If you want to pursue the idea of separate supplies you need to find out why adding the battery did not work.

I assume your receiver is nearby? Has anyone far away (a few miles) confirmed this sound you are hearing? Could it simply be RX overload or RF getting in to the RX where it shouldn't be? How is the RX powered?

You might have a grounding problem with RRC but as Mike suggested it is more likely an antenna issue. There are loads of people out there that use one supply for the rig end (radio and RRC) and one supply for the control end (head and RRC) without any issue. Also, I'm probably not the first person to run everything (2 x RRC, rig and control head) from a single power supply when setting up and testing a new configuration. My take on that is that RRC is pretty immune to problems of ground loops etc.

Could you try to put a dummy load in place of the tuner at the end of the 35ft of coax (checks the cable too) then see what happens?

If the buzzing goes away you have some work to do on your antenna/tuner system because RF is probably getting in to the rest of your gear. If the buzzing is still there you should start a process of elimination that may include supplying the rig RRC from a battery - just to see if it helps.

Regarding internet services, I think it is fair to say that the delivery method is immaterial save the requirement that the radio end must provide an external IP address. There is loads of information regarding internet requirements on this forum.

You say you checked cabling and operation several times. Does that mean you set it up on a local network first and confirm your configuration is ok? If it worked ok over a local network then it's possible that you have something wrong in the RRC network config or more likely in your router forwarding rules at the radio end. 

Can you get to the admin page at the radio end? If yes, your DNS setup is ok and you have an external IP and at least one forwarding rule (port 80) in your router is ok. Go to the RRC status page and you can search for your external IP there. You can also check the DNS status - there is a link you can click. You should see your external IP listed.

For a sanity check it can be helpful to put the radio RRC in the DMZ of your router to make sure everything else is ok. If the system starts working in the DMZ then you need to look at your forwarding rules again.

Lots to investigate but certainly not a lost cause.

Hi Serge,

I posted some links to USB test software the other day.

Since you can connect to the RRC through the manager it is very unlikely that there is something wrong with the interface in the RRC. The USB device view software will help you to investigate this problem. At the very least you should be able to see if the USB drivers were ever installed correctly. To do this you do not need to have a functioning connection to RRC. You can also uninstall individual USB drivers from your PC.

It will only cost you a few hours of time before you order another control unit.

General discussion forum / COM port & USB troubleshooting
« on: 2017-04-19, 04:04:00 »
Hi All,

Recently there has been plenty of discussion regarding USB/Serial/COM port troubleshooting. It can be difficult to guess at what the problem can be in these situations and plugging/unplugging cables can be frustrating.

Some time ago I had some problems with a USB serial connection from a radio to my PC. It stopped me from connecting to my logging program. However I found a FREE product that allowed me to view the comms on this serial line and with that I was able to find a coding error in a configuration file.

While I was searching for a solution I also came across a very neat tool that allowed me to view all installed/connected USB devices on my system. Every wondered why your new USB serial cable comes up as COM 26 or higher? Ever wondered why your USB device is not recognized? This tool will show you why this happens and give you a way to fix it.

I am sure that these tools can help to investigate RRC/USB connection issues as well as many other comms issues you might have.


I forgot to mention, that detailed serial troubleshooting is now easier than ever with some of the great things available on ebay and other places.

Search ebay for "logic analyzer" and you'll find plenty of really cheap (~ $10USD) 8ch logic analyzers. With the appropriate free download software you can save and analyze up to 8 lines and determine level, polarity, speed, protocol etc very quickly.

Nothing really to do with RRC but there are cheap and easy tools out there that can help with the tough problems. You still need to understand the serial protocol and how it works but it is much easier than it used to be.

The RRC system embeds the comports in the TCP traffic between them. I think this process is 100% and can be trusted. In my mind many of these problems are serial problems and probably due to cabling.

First some questions regarding your posts

Are you saying that when you check the serial ports in Windows you see the following?

RRC1258 COM1 (COM2)

Also, did you check at RRC control that  "Use USB Com Port as COM1" = Yes

If these are correct I would say RRC is configured correctly and you should try the following checks. I apologize if you already know this but for many hams the art of serial trouble shooting has never been described.

A simple test is to use basic terminal program like PuTTy to test the serial port over the RRC link. For this I assume you have both RRC boxes in front of you or can at least reasonably access both ends. Hook up your PC as normal to your chosen RRC control com port and loop back (link pins 2 & 3) on the corresponding RRC comport at the rig end. For this I would disconnect the serial cable directly at the rotator and loop back at the connector. If all your connections are correct you should see your terminal program display every key you press. Once this happens you can discount the RRC.

If you get nothing on your terminal screen then this is where you should start your troubleshooting. Check your cable connections for continuity. You must be able to loop back and see responses when you type into your terminal program.

If that is correct and you still can't make the rotator work then you may have a level issue at the rotator end. I would then bring the rotator back to the laptop and using a 'scope measure the levels for TX/RX in a running system then check if you see the same when connected over RRC. Difficult but you should see if it is TTL (5V) or RS232 (~12V).

In summary, it should be simple to test and confirm the RRC serial connection is working. If it is working I would focus my attention to the rotator end of the link.
