Welcome to DVSwitch

[DMR]

Address = 127.0.0.1             ; Address to send AMBE TLV frames to (export)

TXPort = 31100                  ; Port to send AMBE TLV frames to (export)

RXPort = 31103                  ; Port to listen on (import)

Slot = 2                        ; Export slot

ExportTG = 0                    ; Which TG to export

Problem solved.

I followed this great article : https://n2rac.com/dmr-digital-amateur-radio-setup-several-instances-dvswitch-server-3694caaf6bf1

Then : 

# cp /opt/Web_Proxy/ /opt/Web_Proxy2/ -r

# cp /lib/systemd/system/webproxy.service /lib/systemd/system/webproxy2.service

# nano /opt/Analog_Bridge2/Analog_Bridge.ini
and change the following : 
[GENERAL]
pcmPort = 2223
    
# nano /lib/systemd/system/webproxy2.service
and change the following :  
WorkingDirectory=/opt/Web_Proxy2
ExecStart=/usr/bin/node /opt/Web_Proxy2/proxy.js 8081 2223
    

# nano /opt/Web_Proxy2/proxy.js
and change the following :   
var wsPort = 8081,
    pcmPort = 2223;

# systemctl enable webproxy2
# systemctl start webproxy2
# systemctl status webproxy2  

Τhe above procedure ensures that RX-Monitor audio for the second instance will be independent from first instance.
Then
# cp /var/www/html/index.php /var/www/html/index2.php
#cp /var/www/html/include/browserdetect.php /var/www/html/include/browserdetect2.php
#cp /var/www/html/include/config.php /var/www/html/include/config2.php
#cp /var/www/html/include/config.php /var/www/html/include/config2.php
#cp /var/www/html/include/functions.php /var/www/html/include/functions2.php
#cp /var/www/html/include/lh.php /var/www/html/include/lh2.php
#cp /var/www/html/include/localtx.php /var/www/html/include/localtx2.php
#cp /var/www/html/include/status.php /var/www/html/include/status2.php
#cp /var/www/html/include/system.php /var/www/html/include/system2.php
#cp /var/www/html/include/tools.php /var/www/html/include/tools2.php

And edit recursively all "version 2" .php files (starting from index2.php) to point at second instance's locations and also all .php files references to "version 2" .php
I believe you got the point.
Second Dashboard is accessible as http://<IP-Address>/index2.php

address = 127.0.0.1                     ; IP address of xx_Bridge

txPort = 31103                          ; Transmit TLV frames to partner on this port

rxPort = 31100                          ; Listen for TLV frames from partner on this port

ambeMode = DMR                          ; DMR, DMR_IPSC, DSTAR, NXDN, P25, YSFN, YSFW (encode PCM to this f$

minTxTimeMS = 2500                      ; Minimum time in MS for hang delay (0-10000)

; The metadata below is used when ASL is the source since it does not have any concept of digital modes

gatewayDmrId = 310307899                        ; ID to use when transmitting from Analog_Bridge

repeaterID = 310307801                          ; ID of source repeater

txTg = 91                                ; TG to use for all frames sent from Analog_Bridge -> xx_Bridge

txTs = 2                                ; Slot to use for frames sent from Analog_Bridge -> xx_Bridge

colorCode = 1

I'm monitoring the TG from a separate Pi-Star hotspot's dashboard.  When there's an ongoing transmission from a 3rd party and I hit the PTT on my analog radio and release, the connection starts up and I hear 3rd party on my analog radio listening on the ASL side.  However, if the 3rd party stops transmitting and a second 3rd party begins transmitting I don't hear their transmission until I hit the PTT momentarily on my analog radio again.  Also, when I hit the PTT on my analog radio I don't see the traffic pop up on the Pi-Star dashboard.

I'm a total newb at this so just hoping for a pointer as to where to start looking.

Best,
Gerry.

I have installed two functional instances on my Raspberry PI, but so far I managed to have Dashboard only for the first instance.

Any idea or anyone have implemented such a similar task ?
