They include the ADC3, DA3, DAC3, GSB3 (including `-V2` and `/S` variants), MSB3, WSB3 (including `-Hum`), IM3, JA3 and SA3 families, plus GRT3-50, IDRT3-1, IOU3-108M, GBP3-60, GCH3-31, GCR3-11, GDB3-10, GSP3-100, DMD3-1 and RC3-610M/DALI. **Requires CU firmware `02.97.02` or later.** The definitive list is `Advance/Documentation/BUS unit to MQTT.txt`. *** ## Unit modules with a graphical view These 49 unit types have a dedicated terminal diagram in iDM3, showing their connections: | | | | | | ----------- | ------------ | ----------- | -------------- | | `ADC2_40M` | `GSB3-40` | `IM3-20B` | `SA3-06M` | | `ADC3_60M` | `GSB3-40SB` | `IM3-40B` | `SingleButton` | | `DA3-22M` | `GSB3-60` | `IM3-80B` | `TI2_40B` | | `DAC3-04B` | `GSB3-60SB` | `JA2_02B` | `TI3_10B` | | `DAC3-04M` | `GSB3-80` | `JA2_02BDC` | `TI3_40B` | | `DCDA_33M` | `GSM3_01M` | `JA3_02BDC` | `TI3_60M` | | `EST3` ⚠️ | `GSP3-100` | `Keyboard` | `WMR3-21` | | `EZS-Zone` | `HC2_01BAC` | `LBC3-02M` | `WSB2-80` | | `GCH3-31` | `HC2_01BDC` | `SA3-012M` | `WSB3-20` | | `GCR3-11` | `HRS-Room` | `SA3-01B` | `WSB3-40` | | `GMR3-61` | `Hotel-ROOM` | `SA3-02B` | | | `GRT3-50` | `IDRT3-1` | `SA3-02M` | | | `GSB3-20SB` | `IM3-140M` | `SA3-04M` | | *** **See also:** [Chapter 16 — Device manager](/inels-bus/inels-design-manager-idm3/idm3-device-manager-reference.md) · [Chapter 25 — Firmware update](/inels-bus/inels-design-manager-idm3/idm3-firmware-update-manager.md)
