How do I configure the MNET port on the SIEMENS MMB-3 Main Control Board for my MXL System?

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

1. Locate Jumper P7: Find jumper P7 on the MMB-3 board. This jumper controls the configuration of the MNET port (TB1) for either Style 4 or Style 7 operation.
2. Set Jumper P7 Based on Your System:
   • MNET Port Not Used, No NET-7/7M: Set the jumper to positions 1 and 2.
   • MNET Port Configured as Style 4: Set the jumper to positions 1 and 2.
   • MNET Port Configured as Style 7: Set the jumper to positions 1 and 2. Also, make sure to update MMB-3 MNET STYLE 7 to "YES" in the CSG-M, and set configurations 1, 2, and 4 to "NO".
   • No MNET Port, NET-7/7M Present: Set the jumper to positions 2 and 3.
3. CSG-M Configuration Upload (Style 7): When using setting 4 (Style 7), the CSG-M configuration MUST be uploaded through P1 on any NET-7/7M in the Style 7 MNET. You cannot upload the CSG-M configuration via P5 on the MMB-3 in this configuration.
4. Important Note: An MXL panel cannot utilize the MNET Port (TB1) on the MMB-3 simultaneously with a NET-7/7M in the system. Always refer to your SIEMENS documentation for detailed instructions and safety guidelines specific to your MXL System configuration.
