Installing and Running the MPR Buffer Management Utility
To install the MPR-50 Buffer Management utility, unzip the files from the supplied
ZIP file into the LONWORKS bin directory (usually, C:\LonWorks\bin). This step
creates a new directory with four files.
To run the MPR-50 Buffer Management utility, double click the icon for the “MPR-
50Tool.exe” file.
This program requires the following Windows dynamic link library (DLL) files to be
present on the Windows system:
•
LDV32.DLL – for the LDV32 interface
•
MFC42.DLL – for the Microsoft Foundation Classes
This program supports the following Network Interfaces:
•
Supported: USB U10 and RNI (e.g.,
i
.LON
®
10 and
i
.LON 100).
•
Not Supported: IP-852 Network Interfaces.
Using the MPR Program
To check the MPR-50 buffer sizes:
1.
Connect the network interface to any of the MPR routers (e.g., Router 2).

Checking the Current Buffer Sizes
To check the MPR-50 buffer sizes:
1.
Make sure the Buffer Recover Mode button is off (i.e., grey background).
2.
Click the Routers Found Button to clear the list of registered routers.
3.
Press each MPR router service pin. The buffers sizes will be displayed in the Log
Box.
Using Buffer Configure
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; see
Using
Buffer Recover Mode
on page 39 for more information.
Note
: While the Buffer Recover Mode is enabled (the button is orange), when you
press a Service Pin on the MPR-50, the utility tries to recover the buffers for that
router and sets the buffer size to 114 bytes.
To change the MPR-50 buffer sizes:
1.
Decommission all the routers in the MPR-50 if they have been commissioned
before. If the MPR-50 has not been commissioned or if all the MPR-50’s status
