ADDITIONAL HOOKUP INFORMATION

•Comms File

The Comms Setup File contains information about the equipment that is attached to your system. Access the Comms dialog box by clicking on the Comms tab in the Setup 9760 Configuration dialog box. Refer to the Comms Setup File (.SCP File) section in the CM9760-MGR System 9760 Administrative Software Manual for information.

•Pan And Tilt Receivers and Domes

Each port can have up to 16 receivers or domes when using hardwired RS-422 com- munications connected in a daisy chain configuration.

•Ports

Use the System Port Settings Table to determine which ports are not in use. When set- ting up pan and tilt devices for use with the System 9760, edit the Comms file using Pin #9 as the equipment number. Be sure the assigned port’s baud rate and parity match that of the pan and tilt receiver. Refer to the Comms Setup File (.SCP File) sec- tion in the CM9760-MGR System 9760 Administrative Software Manual.

•Peripheral Equipment

Refer to the specific user manual for a description of each device. An RJ-45 data cable is included with each device. Using the Factory Default Port Settings page and the device’s interconnect cable, connect all peripheral equipment to its appropriate data port. If the device is not shown on the Factory Default Port Settings page, refer to the major section Configuring the System 9760 with the Pelco Window Set 9760 in the CM9760-MGR System 9760 Administrative Software Manual. Also, refer to Video In- puts and Video Outupts sections for information on connecting video sources and out- puts.

•CM9760-NW1

This CPU serves as a communications hub when networking two or more System 9760s. This unit includes its own Factory Default Settings table. Use both tables to de- termine which ports are used for data interconnection between the CM9760-CC1s and the CM9760-NW1.

SYSTEM VIDEO CONNECTIONS

For best results, use crimp-on BNCs only. Do not use screw-on BNCs–these typically do not provide adequate ground and signal connections.

DEFINITIONS

Bay Capacity: A single CM9760-MXB can support up to 256 inputs (in increments of 16) and 16 outputs (in increments of 4).

Side Framing: A technique to expand the matrix video inputs beyond 256.

Down Framing: A technique to expand the matrix video outputs beyond 16.

Video Tie Lines: A method for connecting side-framed matrix bays together and networked systems together. A video tie line is a video output from one bay con- nected to the video input of another. In a networked system, a tie line provides the video path necessary to view video from a remote node.

VIDEO INPUTS

SINGLE-BAY SYSTEMS

Refer to the sample drawings in the appendix. Connect all video sources (cameras, VCRs, etc.) to the video input BNCs at the rear of the CM9760-MXB(s). Connect video 1 to the BNC marked “1,” video 2 to the second BNC directly below “1,” and so on until all video cables are connected. If the system is set up for looping, terminate the looped output at 75 ohms.
