How to configure the MNET port on a SIEMENS MMB-3 Main Control Board?

Configuring the MNET port on the SIEMENS MMB-3 Main Control Board for your MXL System involves adjusting jumper settings. Here's a step-by-step guide:

1. Locate Jumper P7: Find jumper P7 on the MMB-3 board. This jumper determines the MNET port (TB1) operation, either Style 4 or Style 7.

2. Set Jumper P7: Depending on your system's needs, set jumper P7 as follows:

   • MNET Port Not Used, No NET-7/7M: Set the jumper to positions 1 and 2.
   • MNET Port Style 4: Set the jumper to positions 1 and 2.
   • MNET Port Style 7: Set the jumper to positions 1 and 2. Then, in the CSG-M, set "MMB-3 MNET STYLE 7" to YES and configurations 1, 2, and 4 to NO.
   • MNET Port Not Used, NET-7/7M Present: Set the jumper to positions 2 and 3.

3. CSG-M Configuration Upload: If using setting 4, upload the CSG-M configuration through P1 on any NET-7/7M connected to the Style 7 MNET. Note that you cannot upload the configuration via P5 on the MMB-3 in this case.

4. Important Note: An MXL panel cannot simultaneously utilize both the MNET Port (TB1) on the MMB-3 and a NET-7/7M within the system.

By carefully following these steps and matching the jumper settings to your system's configuration, you can successfully set up the MNET port on your SIEMENS MMB-3 Main Control Board.
