Problem: Unable to communicate with an NEC projector
If an error occurred when performing any Test operation, follow these troubleshooting steps:
• Conrm the IP address of the projector, or IP address or Windows computer name of the Windows
computer (if using the LAN to RS232 Bridge) is correct.
• If using the LAN to RS232 Bridge utility, conrm that it is congured correctly and has been started. See
“Troubleshooting the LAN to RS232 Bridge” on page 144.
• If the projector is connected directly to LAN (not using the LAN to RS232 Bridge), try connecting to the
projector’s internal web host using a web browser and enter the IP address of the projector to verify
connectivity via HTTP.
• Some projector models require the communications setting to be manually congured between RS232 and
LAN via the On Screen Display. Select the appropriate setting for the connection being used.
