Connection with System Devices
In addition to the WJ-MPU955A, other system devices are
required in order to form the GX System.
System Controllers
A system controller is an operator console, and it provides
a user interface for operators to interact with the GX
System.The system can support up to 64 system con-
trollers.
Ethernet-Based Controllers
To apply Ethernet communication, connect system con-
trollers to the CPUs Ethernet port through an Ethernet hub
in an IP-based local area network.
Ethernet-Based Controller Setup
To add system controllers to the system in Ethernet com-
munication, add an entry to the system controller database
through the admin console. You need to assign a controller
ID for each controller, and enter the Ethernet address from
the bottom of each controller.
Note:Refer to the Admin Console Users Guide for details.

Connections and Configura-
tions for Redundant System
For Manual Switchover Operation
1. Connect the Ethernet cable between the SYSTEM
CONTROLLER ports of both CPUs.
(SERIAL ports are not used for MANUAL operation.) 
2. Set the REDUNDANT YES/NO selector to YES, and set
the REDUNDANT AUTO/MANUAL selector to MANUAL
for both CPUs.
Note:If the REDUNDANT YES/NO and AUTO/MANUAL
selector settings of both CPUs are mixed, the
redundant function does not work properly. In this
case, the ACTIVE indicator of either CPU blinks
fast (around 0.5 seconds on, around 0.5 seconds
off) during operation.

3. Turn both CPUs on. 
4. By using the admin console, click the Get CPU Status
button. When the admin console asks to set default sta-
tus, click Yes 
When switching the CPU to Active/Standby
By using the admin console, click the Switch Active CPU
button on the CPU screen. The Active CPU reboots auto-
matically, and moves to Standby. The other CPU moves to
Active.
For Automatic Switchover Operation
1. Connect the 9-pin D-sub cross cable (locally procured)
between the SERIAL 2 ports of both CPUs, and con-
nect the Ethernet cable between the SYSTEM CON-
TROLLER ports of the CPUs.
2. Set the REDUNDANT YES/NO selector to YES, and set
the REDUNDANT AUTO/MANUAL switch to AUTO. 
Notes:
•If the REDUNDANT YES/NO and AUTO/MANUAL
selector settings of both CPUs are mixed, the
redundant function does not work properly. In this
case, the ACTIVE indicator of either CPU blinks
fast (around 0.5 seconds on, around 0.5 seconds
off) during operation.
•When activating automatic switchover operation,
user should not register a controller to the SERIAL
2 port in the CONTROLLERS section of admin con-
sole.
3. Turn on CPU A until the indicator blinks (around 2.5
seconds on, around 0.5 seconds off.) Then, turn on
CPU B.
When switching the CPU to Active/Standby
When a fatal application software error happens in the
Active CPU, the Standby CPU will switchover automatically.
When a fatal OS system error happens in the Active CPU,
the Standby CPU may automatically switchover but the
Active CPU may need to reset manually. 
Notes: 
•If the Standby CPU also has fatal error, the switchover
is not performed.
•When the 9-pin D-sub cross cable is disconnected, the
Standby CPU will become Active, and the Active CPU
will reboot.

Digital Video Encoder Devices
Digital video encoder devices refer to MPEG2 video encoder devices (WJ-GXE900). They connect to the CPU through an
Ethernet switching hub in an IP based network. Refer to the Operating Instructions of MPEG2 encoder/MPEG2 decoder.
Connect with CPU
The video encoders connect with the CPU through its Ethernet port and one or more switching hub units. The system can sup-
port up to 256 video encoder devices.
Setup from Admin Console 
In order to be added to the GXSystem, an encoder device must be entered into the digital device database. In the admin con-
sole, select Switch Nodes from the Domain menu, select Digital (GX) from the sub-menu that appears, and then enter the infor-
mation for the encoder device. Please note, you need to know the Rotary Switch (SW1 A, B, C) readings from the encoder
device. Rotary Switch settings must be unique for all the encoder and decoder devices. Refer to the Admin Console Users
Guide.
