HARDWARE INSTALLATION
Refer to Appendix A - Connecting PelcoNet to Different Components for diagrams that show various connections.
Connecting Video Sources Or Displays
•To connect a camera, plug a standard coaxial cable into the BNC connector at the front of the trans- mitter. You can connect any camera or other video source (for example, a VCR with a composite PAL or NTSC output). The input accepts color or black and white sources and automatically detects whether it is PAL or NTSC. When using a VCR as an input source, you can improve the video quality by setting the Input Source to VCR in the Video Settings Configuration Page (see the Configuration section). The video input has an internal termination of 75 ohms.
•To connect a monitor, use a standard coaxial cable and plug it into the BNC connector at the front of the receiver. Any PAL or NTSC video monitor with a composite PAL or NTSC input can be connected. Moreover, a VCR can be connected to store the received video on a VCR tape.
The default output format is composite NTSC. To switch the video output to composite PAL, set the Output Standard to PAL on the Video Settings Configuration Page (see the Configuration section). You must then reboot the unit for the change to take effect.
Connecting Audio Equipment
The two audio channels available if the unit has the audio option are called handset and audio in/out. Only one of these two can be active at a time.

The second audio channel is available at the two RCA jacks labeled Audio In and Audio Out at the front of the unit. To choose this channel, select the radio button Line In/Out on the Audio Settings Configuration Page. Level and coding mode settings apply to this channel in the same manner as described above for the first channel.
