Issue
There is a need to connect a legacy MicroNet system to the EcoStruxure Building Operation (EBO) platform. The traditional MN-MI interface is now obsolete, prompting the search for alternative integration methods.
Product Line
EcoStruxure Building Operation
Environment
- Automation server
- Enterprise Server
- MicroNet interface
Cause
The MN-MI interface, previously used to bridge MicroNet systems with EBO, is no longer supported. A replacement solution is required to maintain system connectivity and functionality.
Note: In EBO 2022 (4.0) and later, Satchwell MicroNet Integration is no longer supported.
Resolution
MicroNet systems operate using one of two communication protocols:
- Native Communications Protocol (NCP)
- Attached Resource Computer Network (ARCnet)
If using NCP:
- The MicroNet LAN can be connected directly to the AS-P or ES.
- A MicroNet interface can be added and configured within EBO.
If using ARCnet:
- The MN-MI is required to convert RS-232 to ARCnet.
- The MN-MI connects to the AS-P/ES via an RS232-to-RS485 converter.
-
100 Series MicroNet Controllers:
These may allow removal of auxiliary ARCnet cards and reconfiguration to NCP protocol, enabling direct connection to AS-P/ES. -
50 Series MicroNet Controllers:
These cannot be reconfigured due to integrated communication components on the main board.

For detailed connection options and configurations, refer to document PA-00246.
