Address Switch

The rotary hex switches are used to set the unique address of the matrix modules in the frame. The
purpose of the switch setting is to ensure that each matrix module has a different code. This
distinguishes different frames in a multi-frame system so each is updated with the correct crosspoint
settings. The exact setting will depend on your WinSetup configuration.
A small screwdriver is needed to fit the slot and make the selection. Rotate the switches, which have
16 positions from 0 through 9, then A to F (hexadecimal notation).

Buzzer

The sounder fitted on most matrix modules is used to provide warnings when certain buttons on a
local panel are pressed. This can be enabled or disabled by moving a link adjacent to the buzzer.

Analogue Video Routers

The items covered in this section are specific to the analogue video routers.
Input Coupling Mode
Normally there is a dc restorer on each video input. These restore the sync tips (the lowest part of the
signal) to a voltage of -300mv. Then, irrespective of the dc or average picture level of the incoming
signal, the dc of the black level on the output will be constant.
This is fine for composite video signals, but component video signals: Pr (V) and Pb (U) have the
potential for signal content both above and below black level. A dc restorer is not suitable for such
signals and the signal is dc coupled through the matrix. The restorers are controlled in groups of eight
and can be linked in or out of circuit. The links are located near the edge connector by the input
circuits. For each group of eight inputs there are two links. With the module placed with the handles
nearest you (South) and the edge connectors furthest away (North):
Set the jumper links North, North (DC) for component signals and South, South (ON)
for composite signals.

Address Switches : These switches set the high (upper four
bits) and low (lower four bits) of the 8 bit Q-Link address.
Routers normally have the high switch set to zero giving routers
an address range of 0x00 to 0x0f.
