Digital Video Encoder Devices
Digital video encoder devices refer to MPEG2 video encoder devices (WJ-GXD900). They connect to the CPU unit through an
Ethernet switching hub in an IP based network. See reference [2].
Connect with CPU unit
The video encoders connect with the CPU unit through its Ethernet port (see Panel Detailsy) and one or more switching hub
units. The system can support up to 256 video encoder devices.

Setup Encoder Itself 
In order to communicate with the CPU unit, the encoder device must also be configured. You can access the encoder device
through its Web interface using Microsoft®Internet Explorer. Following is an example of the system layout and information to
be filled into the table.

Digital Video Decoder Devices
Decoder devices refer to MPEG2 video decoder devices (WJ-GXD900). They connect with the CPU unit through an Ethernet
switching hub in an IP based network. See reference [2].
Connect with CPU unit
The video decoders connect with CPU unit through its Ethernet port (see Panel Details y) and one or more switching hub
units. The system can support up to 64 video decoder devices.

Administration Tool
The administration tool (Admin Console) is a system database management software. The software operates in the Microsoft®
Windows®environment. See reference [1] for details.
To connect an administration station with the CPU unit, first install the Admin Console software to a Microsoft®Windows®-
based personal computer, and then enter the CPU unit IP address in the tool’s CPU screen which appears when the tool is ran
the first time. The tool communicates with the CPU using the...

Standard System
The standard system contains one CPU unit. It can handle up to 256 encoder devices, up to 64 decoder devices, one adminis-
tration station, and up to 64 system controllers. The IP addresses in the following diagram are the default addresses of the
CPU network ports.

Main Features
Operator Functions
Operator Area Changes
The system can be divided into multiple areas (up to 64),
and an operator can change from one area to another if
they have the necessary permission. 
Operator Log On and Off
Operators are assigned a user ID and password by a sys-
tem administrator. A user ID and password are required for
any operator to log on to the system. System administrators
can specify to automatically log operators off if there is no
activity for a pre-defined time...

Alarm Programming and
Handling
Program the Alarm
This function allows administrators to program alarms,
assign alarm display targets, and define alarm actions. 
Control Alarm
Alarm controls are operator functions. These functions allow
the highest priority operator to seize the alarm and control
it. These functions also allow the next highest priority opera-
tor to gain control after the highest priority operator releas-
es the alarm.
The alarm controls include:
•Arm and disarm alarms
•Acknowledge...

In most cases, you will not need to change the settings in the sys.ini file. However, if changes are necessary, the MPU955 CPU
must be rebooted.
Text appearing in blue is explanatory, and not part of the sys.ini file.
Interface section
The CPU can incorporate up to three Ethernet network interface cards.
