: Wire the enclosure's physical micro-switch to TB1-4 and TB1-3 (GND) . This alerts the host software if unauthorized personnel open the panel door.
Note: Use twisted-pair, shielded cable (such as Belden 9841 or equivalent) for all RS-485 communication runs. Ensure terminating resistors (120 ohms) are applied at the end of the physical communication line. 4. DIP Switch Settings and Addressing
RS-485 (communicates with standard Lenel or Mercury hardware) Supports up to 32 board addresses Memory 15 MB on-board flash memory Backup Battery 3 V lithium (type BR2325, BR2330, or CR2330)
Form-factor compliant with legacy Software House MR50 enclosures for seamless mechanical drop-in replacement. 📐 Board Layout and Component Identification
If you’re stuck on a particular part – e.g., , addressing multiple modules , or firmware update error – let me know and I can give you a detailed, safe procedure without reproducing the entire copyrighted manual.
Indicates the controller is in factory bootloader mode or requires a firmware flash update via the OnGuard system console.
