X-Rack Interface
D9 female serial data port to facilitate connection to an SSL X-Rack for the transfer of Total Recall information. A suitable 2m
cable is supplied with each X-Rack chassis.
Note: Also included on this connector is a second serial data port for diagnostic and service use.

Network Wiring
To ensure the fastest possible communication between your workstation computer and Matrix, and to simplify the wiring between
Matrix and computer, Matrix communicates with your workstation over Ethernet using the ipMIDI driver to emulate a multiport
MIDI interface. To ensure minimum latency ipMIDI uses multicast UDP rather than TCP/IP. This means that:
• The network connection should be as short as possible and should only use routers that can support high data transfer
rates. Problems have been experienced with some domestic routers, particularly when used with Pro Tools. Typical
symptoms of a slow network connection are:
– The Matrix fails to synchronise all controls when first connecting with the DAW.
– Channel controls and scribble strips on channels 9-16 fail to update reliably when using the
• Because ipMIDI uses multicast UDP packets, messages between one computer and Matrix will be received by all other
computers on the network, potentially causing problems in installations with more than one Matrix. The UDP packets can
be blocked by using a firewall router and connecting the main network to the WAN connector. The firewall can then be
configured to allow all traffic apart from UDP ports 21928 through 21947 which are used by ipMIDI and port 50081 which
is used by the Matrix Remote application. Note that it may be necessary to use a separate Ethernet switch in place of the
integrated firewall router switch, as some of these can not support the high data transfer rate required. The NetGear FS108
(an eight port switch) has been used successfully at SSL Begbroke.
Most systems can be easily configured with a direct connection between Matrix and the controlling computer.
Assigning the Matrix IP Address
By default, Matrix uses a fixed IP address of 192.168.1.2. A dynamic (DHCP) address, can be assigned via the I I P P SSL soft keys
(see Page 44). The currently assigned address is shown in the scribble strip. If Matrix is connected to the computer via a network
switch or router, it should be assigned a D D H H C C P P IP address, otherwise the F F i i x x e e d d option should be used.
Once you have altered the IP mode, you need to turn Matrix off and on for the changes to take effect.
