PC Control Connectors and Cables for NEC Projectors |
v6.1 |
NEC labels the connector for RS232C serial communication the “PC Control” port. |
|
This PC Control port can be used for the following functions: |
|
•Communication from an AMX, Crestron or Extron control system.
•Communication from a PC using the NEC PC Control Utility for basic projector control.
•Communication from a PC using the NEC Geometric Correction Tool for adjusting a projector to display an image on a cylindrical, spherical or corner screen.
•Communication from a PC using the NEC Image Express Utility to send images to the projector for presentations as well as basic projector control, projector lamp and error status or asset management. (These functions can also be accomplished via LAN or USB with models that have a network interface, optional network PC card or USB interface)
NEC uses two types of connectors for the PC Control port, a D-Sub 9pin for larger projectors and a mini-DIN 8pin for smaller projectors due to space constraints on those models.
