RS232 WMI Provider Conguration
About
The RS232 WMI Provider is installed on remote computers that have compatible NEC large-screen displays with an
RS232 communications (COM) port. It will receive queries and commands from the NaViSet Administrator application
via WMI, and communicate these commands to the display via RS232. The WMI Provider is a supplier, or provider, of
the monitor metadata information to the NaViSet Administrator application. It is a completely background process that
gets loaded temporarily whenever a request or command is received and therefore has no interaction with the users on
the remote computers.
!Note: There are several dierent methods of accessing NEC large-screen displays remotely. Please see Appendix A on page
137 which provides a comparison of the dierent types, their benets and drawbacks. Using the RS232 WMI Provider with
a large number of displays connected can result in slow operation since connectivity with each display must be conrmed
before a command can be performed, and is therefore not recommended.
Conguring
Unlike the LAN to RS232 Bridge utility, the RS232 WMI Provider must be locally congured with the number of displays
connected, the Monitor IDs for each display, and the RS232 COM port(s) on the host computer to use.
A utility application called RS232 WMI Provider Conguration Utility is installed with the RS232 WMI Provider to allow
these congurations to easily be made. This is accessed from the Start → Programs → NEC Display Solutions →
RS232 WMI Provider menu.
