BrandMeisterIMRS
Starting BrandMeister release 20190331-203539 has support of directly-connected IMRS repeaters (Yaesu DR2X).
This allows direct communications between DMR talking groups and SystemFusion radio via IMRS repeater without using any additional hardware (unlike WIRES-X) and with audio quality 1:1. As it is with WIRES-X or YSF bridges, a SystemFusion radio may transmit in DN or VW mode.

[hide]Benefits
- Fully transparent calls between DMR and SystemFusion
- Full call signaling support in both directions
- Sound quality is 1:1 in both directions
- No extra hardware is required(*)
- SystemFusion side doesn’t loose any features
- Subscription to multiple talking groups for each IMRS repeater (thanks SystemFusion II)
Conceptual view
Limitations
- Each connected repeater should have unique public IP (limitation of IMRS)
- Due to technological specific up to 99 DG-IDs can be mapped on per master-basis, that means each BM server can bridge up to 99 DG-IDs
Allocated ports
- UDP 21110
Configuration
- // SystemFusionII Repeater with LAN Adapter (IMRS)
- FusionRepeater :
- {
- // UDP Port
- port = 21110;
- // Call of local "repeater"
- call = "CALLSIGN";
- // DP-ID of local "repeater"
- serial = "xxxxx";
- // IMRS TOT Timer (seconds)
- interval = 60;
- // Subscriptions to groups
- subscriptions =
- [
- // <DG-ID>, <Group ID>
- 1, 2501,
- 2, 9504
- ];
- };
Issues with connectivity
DMR radio (and Last Heard) shows talking group number instead ID of operator
- Operator has not registered his call-sign in CCS7 registration system - ask him to register
- CRC check failed during processing of SystemFusion
