7.5 Video looping Connection Configuration
Note: pay attention to the following when conducting loop-
ing video connections.
1.
Two 34-pinflat cable ports are used together with the looping
connector for the looping video connections.
2.
Please refer to the above picture for the connection between
the 34-pin flat cable ports and the looping connector.(refer
to Picture 6-5 for port numbers)
3.
The BNCvideo port of the looping connector is connected to
the matrix BNC video input po rt with the same numbe r. For
example, The No.1 BNCvideo port Of the looping connector
is connected to the No.1 BNC video input port of the matrix.
4.
The looping connector can connect the o utput video from
the matrix to other equipment. On the other hand the loop-
ing co nnector can also connec t input video to the m atrix,
but now the BNCvideo input port with a certain numberin the
matrix can only be connected to the video from the cam-
era with the same number as its ID address.
7.6 Alarm Input Connection Configuration
Note: pay attention to the following when conducting alarm
input connections.
1.
Each matrix has 32 built-in alarm inputs (can be extended to
128 inputs). Two alarm modes of Normal O pen and Normal
Close are available.
2.
Each alarm detector must be connected to an alarm signal
transmitting line and must be grounded simultaneously.(refer
to Picture6-4 for port numbers)

3.
Every two alarm signal transmitting lines have the same ground
wire. All the ground wires must be connected.
4.
The alarm area number of each detector must be the same
with the num ber o f the alarm input port in the matrix (the
numbers are silkscreened on the back panel). For example,
if the alarm input port is No.1, its corresponding alarm area
must be set as No.1.
