Patch Panel Overview
The MegaPower 48+ patch panel contains 8 sections for video switching, communications, power, alarm handling, and
auxiliary control. The patch panel also contains a diagnostics section providing system status signals. See Drawing 6,
Page 13 for an illustration of the patch panel.
A brief description of each patch panel section follows.
Video Inputs Section (Camera Icon)
The video inputs section provides 48 BNC connectors for connection of RG-59U video cables to system
cameras and domes. Cable distance should not exceed 1000 feet (330 meters).
Video Outputs Section (Monitor Icon)
The video outputs section provides 16 BNC connectors for connection to system video monitors and/or
recorders. Monitors 1-8 display video and a text overlay that provides information about the displayed
video. Monitors 9-16 display video with no text overlay.
Relay Section (Switch Icon)
The relay section provides two three-position screw terminal blocks for connection of form C relay outputs.
Terminal positions are normally open, normally closed, and common.
Alarms Section (Bell Icon)
The alarms section provides two 16-position screw terminal blocks for 16 normally open alarm contact
closure wires and 16 alarm ground wires.
Diagnostics Section (Wave Form Icon)
The diagnostics section provides indicators for the presence of AC power (sine wave icon), normal
system operation (heartbeat icon), and four LEDs to display status signals. This section also provides a
push button system reset switch.
Communications Section (Dome Icon)
• SEC-RS422 : Provides two twelve-position screw terminal blocks for connection of up to six RS422
devices such as AD domes and J-Boxes.
• AD Manchester : Provides one three-position terminal block for the connection of a single Manchester
device such as the AD1691 Code Distributor or the AD1641M Receiver/Driver.
• SensorNet : Provides two six-position screw terminal blocks for the connection of up to six SensorNet
devices such as AD domes or J-Boxes. An adjacent six position DIP switch allows for termination of
each SensorNet port.
Power Section (Sine Wave Icon)
The power section provides either a female power connector that connects directly to the provided
transformer cable.
RS232 Section (PC Icon)
The RS232 section provides eight RJ45 jacks for connection of RS232 devices such as PCs, ADCC1100,
ADCC0200, ADCC0300, AD2079, AD2088 and ADTTE keyboards, Port Expanders, AD2096A Alarm
Interface Units, and standard external modems.
A ninth RJ45 jack is provided for Ethernet connection to a PC or for network connections in a multi-
matrix system.
Modem Section (Telephone Icon)
The modem section provides a DB9 connector for the connection of a standard external modem for
message paging functions.
Note : either the DB9 connector or RJ45 jack number 8 of the RS232 section can be used as an alternative
port for an external device - either connector is recognized as Port 8 by the MegaPower 48+ system, but
both connectors cannot be used at the same time.
