Working Config Example QB P25GW

jacomms
 

Hi
I am very new to Quantars and am setting up a few for our network.
The setup is Quantar connected to 1841, Pi connected to the 1841, 1841 connected to the site router.
The 1841 config seems fine, its just the QB & MMDVM ini files im guessing.

or is there a ISO pre built for the Pi floating around for this setup??

Looks great! Thanks Tom! 

One correction I think needs to be added however (unless I've missed it myself), this should be added on page 11 after the "cd /tmp" step:

The document will help you build an ASL <-> P25 Bridge (includes a P25 Reflector) This is a no frills document. Tom shows you what files to edit and what fields to change. Includes some basic troubleshooting tips.

I like the simplicity of this. One of my favorite parts is that Tom ONLY changes the fields that need to change. Nothing more. Since the covers Analog_Bridge, MMDVM_Bridge and P25Gateway this is a good document for anyone bridging to P25 or connecting a Quantar to the P25 MMDVM Network for that matter. The document highlights one of the most basic principles of DVSwitch. That is the fact that most of the default settings just work. You don't have to edit every field in every file. If you understand the basic concept of DVSwitch you can get up and running pretty quickly. I'll leave it at this since it tells most everything you need to know:

 

A very large thank you to Tom for taking the time to create the document.

Thanks Florian for the reply.  I'll go try to find that PDF.  In the meantime, I did order some DCE cables.

Regards,

Re: CAB-SS-232MT instead of CAB-SS-232FC Cable

Florian Wolters
 

Hi Paul,

switching RX/TX is only half of the solution. There are internal bridges of pins which tell the device whether it is DCE or DTE. See cisco's papers about the details. AFAIK there was a PDF describing these.

Hey guys, I ordered the wrong cable and was wondering if I can just reverse TX/RX because it's DTE or is there something else going on with clocking and signaling of the cable that would prevent me from using it?

Thanks in advance!
Paul

It is a P25 Repeater, so back into the MMDVM P25 network.  I run a local test reflector already.  End user can change the Reflector to say TG10400 (Pacific) at will http://pacificp25.repeaters.info/ or any other as required

Good starting point, be sure you have the V.24 Card in the Quantar and a 60 Pin Serial Card in the Router. You will also need a  CIsco CAB-232FC Cable.

You will also need to make a DB25 to RJ45 adaptor as per the wiki https://dvswitch.groups.io/g/Quantar-Bridge/wiki/5817

 

I hope this helps, I am in the process of doing the same myself and have been guided VK2ERG

Good Early morning folks! So I recently acquired a Motorola Quantar never used believe it or not. It was from my father. He recently passed last month 6/10 so he is SK. Our project was to get the repeater up and running the weekend he passed. So I took it upon myself to continue what he always wanted. W3NTT was his call. 

 

I started off in the digital world of radio and not much of analog. But i can program analog machines, alignment, and so forth. 

 

So with that being said I will be getting a 1841 given to me for linking purposes. I am not familiar with this forum. Didn't even know it existed to be honest. So I wanted to know what all can this router do or link to with the quantar. The repeater is up and running 2 days after he passed. 

 

Can someone give me some information please on what these can do with the repeater? That would be great. Again, thank you all in advance.

Re: mmdvm_bridge not starting

Edited

cat /proc/cpuinfo shows an ARMv6 compatible processor. I'm guessing I need the MMDVM_Bridge binary from this thread: 

https://dvswitch.groups.io/g/main/topic/mmdbm_bridge_segfault/70039157?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,20,70039157?

*edit*

Downloaded and renamed the file, changed the permissions and it looks like things are up.

Now I've got an mmdvm_bridge.log file which appears to show I'm up and running. Quick test on Parrot and I'm good.

Thanks for everyone's help.


Re: mmdvm_bridge not starting

Steve D. Jones
 

Tried a fresh install, created a user mmdvm with password mmdvm with full read/write access to var/log/mmdvm and copied the Quantar_Bridge.ini file to /etc/ with no changes.

systemctl shows quantar_bridge.service, p25parrot.service, md380-emu.service and p25gateway.service all loaded, active and running. mmdvm_bridge.service shows loaded and activating but eventually it does dead.

Running ./MMDVM_Bridge from the /opt/MMDVM_Bridge/ directory gives me a Segmentation fault.

Re: mmdvm_bridge not starting

If you haven’t already create a user named “mmdvm”, password mmdvm and give it full read/write access to var/log/mmdvm . I also had to manually place Quantar_Bridge.ini in the main /etc/ folder.

 

The flow of data is Quantar_Bridge -> MMDVM_Bridge -> P25_Gateway. Check to make sure all three of those programs are running. I have had issues with P25_Gateway not installing correctly from the package installer and had to download and recompile it from Github.

Re: please update cisco v.24 info?

Ken KE2N
 

Thanks John.  I don't know why, but when I searched for the cisco serial card 1-2 months ago, the only thing that came up was the HWIC cards (-1T in this case).  But you are right, searching anew tonight, I see the WIC cards with 60-pin connectors.

My problem has been in identifying the correct cable to use.   Steve just said he is using the exact same part number as the one I just ordered and he has the WIC card which I understand has the 60-pin connector on it.  Yet the vendor photo of the cable I ordered shows a 26-pin connector. So its confusing to say the least.  In another week I will know if it's the right cable.   Thank you for confirming that (1) it must be the cable with the female DB25 and (2) the wiring to the Quantar is the same.    I plan to cut a cheap Ethernet cable in half and solder the leads to a male DB25 connector, to complete the connection

73,  Ken


Re: please update cisco v.24 info?

John ZL4JY
 

I wrote the original information in a series of posts on another forum when describing how to use the Cisco routers for Quantar linking.

The DB25 RS232/V.24 connector on the far end of the Cisco cable has the same interface no matter if you purchase the cable for a WIC-1T with the 60pin card connector or the WIC-2T with the smart serial connector. Remember that the female connector is the DCE type you want.

The information is not out of date as not only is the WIC-1T still available but the 4 port and 8 port cards use the same 60 pin on-card connectors.

is your serial card really a WIC-2T or an HWIC-2T?   The former uses the 60 pin connector (I believe) and that cable you mention (Identical number to the one I just ordered - above) has a 26 pin connector (the card has two 26-pin connectors in the case of the -2T).

the HWIC (not the WIC)
