For the sake of demonstration, we’ll assume my DMR ID is 3999999. With DMRGateway, for multiple networks to be connected and used at the same time there is talk group translation using 7 digits, e.g. TG 31665 on TGIF would be 5031665 where talk groups 5000001 through 5999999 are rerouted to TGIF with the 5 and leading zeros removed (and translated back on receive). And everything not covered by translation rules go to Brandmeister, but the problem is that 3999999 or whatever your DMR ID is might be covered by another network’s translation rules. One way around this would be to hardcode the translation into the Brandmeister network section of DMRGateway. And as memory serves, these translation rules progress down the file until they hit a matching rule and execute with Brandmeister usually first.
SrcRewrite=2,3999999,2,3999999,1
TGRewrite=2,3999999,2,3999999,1That got us working for using our DMR ID 7 digit talk group on Brandmeister which is usually everyone’s main network, but how would you use this at the same time on the TGIF network? An easy work around would be to use the network translation number as the first digit and the rest of your DMR ID number, e.g. 5999999 would get translated to 3999999 and back on TGIF. The downside is you lose access to talk group 999999 on TGIF if it even exists. But you could translate around it if needed. And you’ll see your personal talk group come in on TGIF as 5999999, but you know it’s really your DMR ID 3999999. Notice how I made sure these translation rules are before the other translation rules to get picked up first.
TGRewrite=2,5999999,2,3999999,1
TGRewrite=2,5000001,2,1,999999
PCRewrite=2,5000001,2,1,999999
srcRewrite=2,3999999,2,5999999,1
SrcRewrite=2,1,2,5000001,999999Another option would be to use VE3RD’s DMRGateway which has network isolation where you select the network with 900x, e.g. to switch to network 4 you’d transmit TG 9004. And the beauty of this system is you just use the regular talk group number on each network with no need for talk group translation. My particular solution is to have both DMRGateways available and switch between them with a script. So if you want to monitor multiple networks with talk groups that aren’t super busy, use the regular DMRGateway, but if you want to monitor busy talk groups or use 7 digit talk groups, switch to VE3RD’s DMRGateway (I’m currently using VE3RD DMRGateway version 4 but he’s come out with version 5 and 6 with added ways to configure with XLX support).
DMRGateway-6 2024-03-10
« on: June 09, 2023, 05:27:39 pm »
2023-06-09 DMRGateway-5 Created
2024-03-10 Updated/Upgraded to DMRGateway-6
NOTE: READ EVERYTHIMG BEFORE DOING ANYTHING.
Reminder: This DMRGateway version was developed to add the filtering that is missing in the pi-star version and to provide a method to handle 7 digit talk groups
This version adds filtering to lock a network such that none of the other networks will bleed through to the radio and
stop the hotspot from arbitrarily switching talk groups based on network activity and
stop the hotspot from going into tx mode from an unwanted network activity thus missing activity on the tg the radio is tuned to.(ie: Busy light – no audio)
A new parameter RawNet was added to /etc/dmrgateway in the [General] section
if RawNet=0 the DMRGateway-6 will not assume one of the networks is running in RAW Mode.
if RawNet=1 to 6 then the designated net will be handled as Raw Mode regardless of whether or not you are running the rest of the DMRGateway in 7 Digit or 8 Digit Mode.
ie:
Assuming Net4=TGIF and Net5=MNET and GWMode=8
if Rawmode=4, then
31665 will put you on Net 4 TGIF 31665 (Raw Mode)
15031665 will put you on Net 5 MNET 31665 (8 Digit Mode)
if GWMode=7 then
5031665 will put you on Net 5 MNET 31665 (8 Digit Mode)
This version runs in one of three modes.
1) Raw Mode – Radio on 31665 will use 31665 to the server.
TG9001 to 9006 will select and lock Network 1 thru Net6 similar to the openspot profile selection.
This will handle 7 digit talk groups
2) 7 Digit Mode. the left most digit 1 thru 7 will select and lock the corresponding network.
ie 4031665 will select 31665 thru network 4 to the server.
This mode WILL NOT handle 7 digit talk groups.
3) 8 Digit mode. The left two digits 11 to 16 will select and lock the corresponding Network 1 to Network 4
ie 14031665 will select 31665 thru network 4 to the server.
This mode will handle 7 digit talk groups via ReWrite rule.
TGRewrite1=2,1000001,2,1000001,5599999
Note: Sending TG9007 will turn off all DMRGateway Networks and enable XLX regardless of what mode was previously selected.
Sending a 9001-9006 or a 7 digit or 8 digit TG will turn off XLX and enable the corresponding mode and Network
Note: Network 6 has a high number limitation. It will only accept just under 2^24 = 16,777,216
which translates to approximately 777200 as the highest TG accessible.

6 “Install DMRGateway NO Config File Update”
7 “Restore Original DMRGateway Binary File”
8 “Quit”)
BASIC INSTRUCTIONS
Item 1:
This will create and/or edit a password file. (Required for a new Install)
This is used to enable desired networks and allow an off line repository for
the Network security codes. This is mandatory for a new install.
Item 2, 3 and 4 Common:
This will overwrite the /etc/dmrgateway file with a default version and
will compile a new Binary if required and
will install the New Binary DMRGateway File
Item 2
will proceed with a limited configuration Using Basic Mode
In the Radio CPS use basic 31665 for 31665 on the Server
Key on Tg 9001 to 9006 to select Network 1 to 6
This will allow the use of 7 digit talk groups
Item 3
will select a network that will run in basic mode. A zero will default to no network in basic mode.
If selected this network will handle 7 digit talk groups with the rule
TGRewrite1=2,1000001,2,1000001,5599999
Item 4
will proceed with a limited configuration Using 8 Digit Translation Mode
In the Radio CPS use 14031665 for TG 31665 on Network 4 etc.
This will allow the use of 7 digit talk groups.
Item 5
will proceed with a limited configuration Using 7 Digit Translation Mode
In the Radio CPS use 4031665 for TG 31665 on Network 4 etc.
This is the same as the default Pi-Star gateway but will not allow
the use of 7 digit talk groups unless you select a raw mode network as described above.
Item 6:
will Ignore the existing Configuration File and
will Compile a new Binary if Required and
will Install the Binary File
Item 7:
will Restore the Original DMRGateway from /usr/local/bin/DMRGateway.orig
( If it exists )
CAUTION: This script can not possibly handle all users special situations
Use nano /etc/dmrgateway to check and configure what the script misses
————————————————————————————-
Note 2021-06-19
The Pi-Star update dated June 17, 2021 overwrites the DMRGateway Binary file with a Pi-Star Default.
Re-Running the ./binupdate.sh script in the DMRGatewa-5 directory will re-install DMRGateway-6 Binary
I have added a script in the DMRGateway-6 directory called GWConfig.sh That will help to install the DMRGateway and
Configure it according to information found in /etc/mmdvmhost.
Follow the instruction indicated below titled INSTALLATION of DMRGateway-6
The following is a typical rule set for Network 5 in 8 Digit Translation Mode
TGRewrite0=2,15000001,2,1,999999 // Talk groups 15000001 to 15999999 = 1 to 999999 Max 6 digits
TGRewrite1=2,1000001,2,1000001,5599999 //Allows use of 7 digit talk groups after Locking (use of any 8 Digit TG)
PCRewrite0=2,15000001,2,1,999999
SrcRewrite0=2,1,2,VE3RD,9999999
I: 2023-06-11 11:05:24.414 Rewrite RF: 2:TG15000001-TG15999999 -> 2:TG1-TG999999
I: 2023-06-11 11:05:24.414 Rewrite Net: 2:TG1-TG999999 -> 2:TG15000001-TG15999999
I: 2023-06-11 11:05:24.414 Rewrite RF: 2:TG1000001-TG6599999 -> 2:TG1000001-TG6599999
I: 2023-06-11 11:05:24.414 Rewrite Net: 2:TG1000001-TG6599999 -> 2:TG1000001-TG6599999
I: 2023-06-11 11:05:24.414 Rewrite RF: 2:15000001-15999999 -> 2:1-999999
I: 2023-06-11 11:05:24.414 Rewrite Net: 2:1-9999999 -> 2:TG0
XLX added to this version
Sending a TG9007 will turn on XLX Mode and shut down all DMR Networks
Note: Audio comes back on TG6, if turned on.
My Arrangement
8 Digit Mode
Net 1 BM 11xx
Net 2 DMR+ 12xx
Net 3 YSF2DMR (when used) 13xx
Net 4 TGIF 14xx
Net 5 MNET 15xx
Net 6 Not Used 16xx
xx=000000
I think of XLX as Network 7.
