    Applying Power to the MPR-50 Multi-Port Router Connect earth ground, if available, to terminal 3. Then connect 9–28VAC (40–70Hz) or 9–35VDC power to terminals 1 and 2—the power terminals are polarity- insensitive so the polarity of the DC input is unimportant. The green Power LED will illuminate to indicate the unit is powered and the Status LEDs will begin operating within seconds.

    LED Legends The Power LED will illuminate whenever power is connected to the MPR-50. The following two tables describe the behavior of the Status LEDs for the Monitor and for Routers 1–5. For easy reference, shortened versions of the Status LED legends are printed on the front panel of the MPR-50.

    Buffer Management Utility The MPR-50 Buffer Management utility is a stand-alone Windows program that allows you to: • Change the MPR-50 Network buffer sizes. • Fix the buffer settings if they become corrupted (for example, if they are set to an invalid number).

  • Page 45: Installing And Running The Mpr Buffer Management Utility

    To configure the MPR-50 buffers, you first need to configure the MPR-50 for repeater mode. If you are unable to configure the MPR-50, or it is not working, then the router buffer settings might be corrupted. To fix them, use the Buffer Recover Mode on the routers before changing the buffer sizes to the desired values;...

    TP1250 configuration is quite large. To correct for this difference, after the recovery process is complete, you should re-configure all five routers using the normal buffer configuration mode. Fixing the MPR-50 buffers because of a corrupted buffer can take several attempts to fix all five routers. To fix the MPR-50 buffer sizes: 1.
