Intesis Samsung NASA BACnet Instance Calculator
Free browser tool · nothing is uploaded · 5 November 2026
The Intesis BACnet server for Samsung NASA gives every indoor unit a block of objects at its MAPS identifier x 100.
Indoor unit instance = identifier x 100 + offset, where the identifier (1-64) is the number assigned to the unit in Intesis MAPS. Identifier 14's room temperature is AI 1401 and its on/off command is BO 1400.

The calculator needs JavaScript. The formula and a worked example are below.
Which unit does this instance belong to?
How the numbers are built
instance = identifier x 100 + offset
| Part | Meaning | Range |
|---|---|---|
| identifier | Indoor unit identifier assigned in Intesis MAPS | 1-64 |
| offset | Object offset in the unit's block | 0-8 |
The identifier is assigned in Intesis MAPS after scanning the bus; it is not the unit's NASA address (indoor 0-63, outdoor 0-15). Outdoor communication errors are fixed at BI 0-15.
Worked example: identifier 14
The first objects for identifier 14 on the INBACSAM, worked out with the formula above:
| Object | Name (as printed) | What it is |
|---|---|---|
| BI 1400 | OxxUxx_On/Off_S | On/Off (status) |
| BO 1400 | OxxUxx_On/Off_C | On/Off (command) |
| MI 1400 | OxxUxx_Mode IU/AHU_S | Mode indoor unit/AHU (status) |
| MO 1400 | OxxUxx_Mode IU/AHU_C | Mode indoor unit/AHU (command) |
| AI 1400 | OxxUxx_Setpoint_S | Setpoint (status) |
| AO 1400 | OxxUxx_Setpoint_C | Setpoint (command) |

Formula and objects from Intesis BACnet Server - Samsung NASA AC User's Manual · rev. 01/2022 r1.3 (manufacturer document ↗), re-typed in our points list. Object names are shown as printed.
Check it against the live device. The calculator applies the formula from the manufacturer’s documentation; the gateway in front of you may expose fewer objects or use other numbers after a firmware change. Easy BACnet scans a network for BACnet IP devices from an Android phone and reads every object on them — a quick way to confirm one unit before you map a whole building.
Questions
How do I work out a Intesis instance number?
Indoor unit instance = identifier x 100 + offset, where the identifier (1-64) is the number assigned to the unit in Intesis MAPS. Identifier 14's room temperature is AI 1401 and its on/off command is BO 1400.
Is this the same as Samsung's own MIM-B17BN gateway?
No. Samsung's DMS2.5 BACnet gateway makes one virtual device per unit; this Intesis server puts every unit in one device. Use the Samsung MIM-B17BN calculator for that gateway.
Is this Intesis calculator official?
No. It applies the formula printed in Intesis's own documentation to the points list in our library. Confirm the numbers against a scan of the live device before you map or write anything.
