Define a Video Switch Node
●
GX Switch Node
A GX switch node consists of one or more video decoder devices (WJ-GXD900) and video encoder devices (WJ-
GXE900). A GX switch node can be in a single system domain or across multiple system domains. Currently, the
system only supports one GX switch node, and the node ID is always set to zero by the system software.
●
GX Switch Node and its Domain
For each GX switch node, there can be many encoder and decoder devices. In the case of a single domain system,
such as the system on page 11, all the encoder and decoder devices will be assigned to that domain.
The GX node can split into multiple system domains. In the case of a multiple domain system, the system designer
has to decide which domain the encoder and decoder devices should belong to.
For the system on page 15, we decided that encoder 1-1, encoder 1-2, and decoder 1-1 are in domain 1, while
encoder 2-1, encoder 2-2, and decoder 2-1 are in domain 2.
In general, we recommend that you should search for a nearby CPU and assign encoder or decoder devices to the
same domain ID of the CPU.
●
Enter Encoders and Decoders in the WJ-ASC960 Admin Console
After deciding the domain ID for each encoder and decoder, the next step is to enter the encoder and decoder
device information in the WJ-ASC960 Admin Console for the domain.
In the WJ-ASC960 Admin Console
GX DEVICES
screen, we need to configure the devices here.
Since these devices are part of the digital node, select
GX
from the
Switch Nodes
command on the
Domain
menu.

SX850 Switch Node
SX850 switch node consists of one or more WJ-SX850 cages with WJ-PB85C16/WJ-PB85M16 (MXSW) and other
matrix controllers (WJ-SX850). SX850 switch node can only be located within a system domain, and cannot cross
over multiple domains. Currently, the system only supports up to one SX850 switch node in a single system domain,
and the node ID is always set to its domain ID by the system software.
