Hi Jim,

My pleasure. Let me know if you have any further questions.

Networking Checklist
*NOTE: If you have one of the newer RRC’s with the new port numbers (13000-13002), then you can ignore section 6 and correct section 11b.

1) This is a two or three step process: First step, you get the RRC’s working within the same network. Second step, only then do you move the control RRC offsite and try to use it. Otherwise, debugging will be significantly more difficult. The third step is that if you intend to use the control RRC with a 3G/4G network, make sure if works first on step two using a standard broadband network. Otherwise, the debugging will be very difficult if it doesn’t work.

2) Assuming your router is running a DHCP server (NAT) as most do, then use the Setup Manager to change the radio RRC to DHCP. Ignore what is written in the IP fields, since this is completely irrelevant.
COMMENT: The reason I suggest this step, is because the factory default uses a fixed intenal IP number that is often incompatible with home networks (different subnet). This step makes sure that the RRC books into the network and can reach the internet.
COMMENT: Make sure that you are connected to the router/modem that is the one that is used to access your internet provider. Never connect to a cascaded second router with DHCP turned on, which will never work (called “double NAT”).
COMMENT: Make sure that “SIP ALG” is turned off on any router used on the radio or control side.

3) Click on the Net Info tab and the get your new IP number (wait about 30 seconds). You can go from there to open up your browser and go directly to your RRC to make further changes. Note this new internal IP number (192.168.XX.YYY), it is critical for the following steps.

4) Do the same for the control RRC
COMMENT: It is critical to have the control RRC using DHCP if you intend to move this RRC around different external networks. Otherwise, it will never pull an internal IP number off of a different network and nothing will work

5) If you insist on having a different internal IP number as your router provided, I suggest that you assign the radio RRC MAC address (IP address “bind”) in the router under the NAT or similar menu. This step should be unnecessary, unless you have a problem remembering the internal IP number, or if your router requires this for port forwarding or the DMZ (you can save as a bookmark in your browser).

6) *Using the browser, go to the Advanced Settings and change the SIP port to something else other than 5060 (mainly because of conflicts with routers that already use this port for for VoIP).
COMMENT: This change is very important, my list is very long of those that skipped this step, only to find that it didn’t work when they tried connecting from outside, because the router already used port 5060.

7) I also recommend that you change the web server port and telnet server port (radio RRC only) for the same reason. You should change the web server port from port 80, otherwise you will always land on your router directly from outside your QTH, which usually uses port 80.
COMMENT: Unless you use a VPN, this step is very important to allow you to be able to access your radio RRC when away from home to make adjustments, etc. Don’t skip it!
COMMENT: If you do forward the web server port, you should place a password in the web page user and password fields (under IP settings), otherwise someone can reconfigure your RRC if they find your IP number!

8) From that point, you need to always add the port to your web call-up, e.g. (change your browser bookmark from step 4 above). To access your radio RRC’s web interface from outside of your home network, you will need to add this port number (e.g. :1234) to the Dynamic DNS address that you use under point 11 below.

9) Go to your control RRC and change the SIP port to match the radio RRC.

10) Optional: change the control RRC web port to a different web port, but not the same as the radio RRC (remember this number and change your browser bookmark as well!).
COMMENT: This change is optional and not really recommended, since you will always likely be accessing the control RRC locally. I always leave mine at port 80, since I don’t access my control RRC’s outside of the control location and never forward the control RRC’s port.

11) Go to your router and do only one of the following:
a) EITHER move your radio RRC into the “DMZ” (exposed host). Your router may require the RRC to have a fixed internal IP number. If so, just do so as I described in 4) above
b) *OR else forward the ports: 12000 (UDP), 11000 (UDP), SIP port you gave (UDP) and web server port you gave (TCP). It is not necessary to forward the telnet port in most cases.
c) Do NOT do both!!!
COMMENT: This step is very critical for the radio RRC, it won’t work from outside of your network without it. Note that this is NOT necessary or recommended for the control RRC, only the radio RRC!
COMMENT: If you need help with port forwards, go to the web site for assistance

12) If you do not have a fixed external IP number at the radio QTH, then create a Dynamic DNS account, unless you have one already from Since DynDNS started charging for their accounts, Microbit began their own service for their products. All you need to do is to:
– Go to the Dynamic DNS settings tab (radio RRC only)
– Change the check interval to i.e. 10 minutes
– Make sure the drop-down is on RemoteRig’s service
– Click on apply changes
The Microbit Dynamic DNS address is entered automatically into the “own host name” field if you use this service. If you are using DynDNS instead, then enter that address into either your radio RRC under the DynDNS settings, or into your router’s DynDNS setting. Note that if you do already have a Dynamic DNS account (either paid, or an older free one) and prefer that over the one from Microbit, then I suggest you use your router’s DynDNS setting if available, since it only updates if there is a change.  Never enter the same DynDNS account into more than one device! Also note that the default RRC setting of 10 minute updates causes DynDNS to lock your (free) account, so change this to 24 hours, but leave it at 10 minutes if using the RemoteRig service.
COMMENT: Even if you believe that your external IP number never changes, make this step anyway! Your ISP can change the address on a whim, or a power outage, even for a split second, can change the address. I have had a couple of cases where this was skipped and the user could not access for several weeks until they reached the station again.

13) On the control RRC, place the information from the radio RRC’s “own host name” on the Radio Settings tab under SIP contact. When testing at the same QTH as the radio, you should temporarily place the radio RRC’s internal IP number (i.e. 192.168.XX.YYY) into this field, just don’t forget to change it when you take the RRC with you. Note that this address is WITHOUT a port suffix (e.g. :1234), since the SIP port is entered into the SIP contact field separately. Everything should work now. Just don’t forget to switch to the Dynamic DNS address when using outside of the station, this is the #1 cause of the system not working when leaving your local network this first time!
COMMENT: Note that using the external IP address or Dynamic DNS address from inside of your network will often not work (blocked by the router), you usually must use the internal IP number. Using the internal IP address from outside of your LAN will never work!

14) All other settings are optional and MUST be the same on both RRC’s, e.g. SIP password (be careful on spelling), audio quality, etc. Use the handbook to understand them. Exception: if you use the RRC Micro PC Client to access your radio RRC, then you can make changes in that software that makes these changes only for that session.

15) Note that I have separate checklists for setting-up remote CAT control, CW and optimizing for 3G access or low bandwidth networks. Let me know if you need either of these.

16) Have fun!



Hi Jim,

Glad you got things working ok. I included my other checklists for you.

To use a sound card digital mode is very easy: just plug your sound card interface into the RRC instead of a rig, i.e. audio to AUX/MIC jack and take audio from the SPK jack. Otherwise, I think your other questions are covered below, otherwise just let me know what you need.


CW Checklist
on the radio RRC:
– under keyer settings, set PTT activated by keyer to YES
– under I/O settings, change OUT2 mode to KEYER

on the control RRC:
– under keyer settings, set enable to YES
– change other keyer settings as desired
– under I/O settings, set IN0 mode to KEYER

Make sure that the cable is connected between the radio RRC and rig’s key (NOT paddle) jack. If possible,
use a mono plug on the rig side, since stereo can cause problems under certain situations (e.g. FSK).

IMPORTANT: In both scenarios, you MUST first install a standard serial cable between the TS-480 body and COM2 of the radio RRC!

1) Change the CAT rate on the TS-480 to 4800 baud (menu 56). This rate keeps traffic over the internet to a minimum and faster is not necessary for CAT.

2) Change the COM2 serial settings of the radio-RRC to mode-4, 4800 baud, data bits 8, stop bits 1 and submit/apply changes.

3) Change the COM2 serial settings of the control-RRC to mode-4, 4800 baud, data bits 8, stop bits 1 and submit/apply changes.

4) Plug a serial cable in between your PC and the control-RRC COM2

5) Set your software to use the correct COM port on your PC at 4800-8-1-N

1) Change the CAT rate on the TS-480 to 4800 baud (menu 56). This rate keeps traffic over the internet to a minimum and faster is not necessary for CAT.

2) Change the COM2 serial settings of the radio-RRC to mode-4, 4800 baud, data bits 8, stop bits 1 and submit/apply changes.

3) Install the Microbit Setup Manager if you already haven’t. You don’t need the problem for this, but this installs the correct drivers on your PC.

4) Change the COM2 serial settings of the control-RRC to mode-4, 4800 baud, data bits 8, stop bits 1, “use USB Com Port as COM2” to “Yes” and submit/apply changes.

5) Plug a USB cable between your PC and control-RRC. Make sure you do NOT do his before step 3 above!

6) Find out the correct port in your Windows Device Manager to use by looking for the “Microbit RRC Virtual COM Port (COM2)”

7) Set your software to use the this COM port on your PC at 4800-8-1-N.
