Model, Location & Purpose: These three text lines are available for you to include relevant notes about
the unit. Up to 11 characters can be entered on each line.
24/12: The 24/12 parameter, located at the bottom of the center column of each matrixer control block, is used to
identify the matrixer model. This parameter must be manually set since all matrixers appear alike to the IQ System.
It has only two settings, “24” and “12”. Use the “Space Bar” to toggle it from one setting to the other. Use “24” for
MRX-24 and MRX-24S models. Use “12” for MRX-12 and MRX-12S models.
9.2 Using a Control Block to Monitor & Control a Matrixer
The simplest way to monitor or control a matrixer is from its control block. The matrixer controls within it serve the
dual purpose of both showing their on/off state and allowing the user to control their state. Section 9.1 described
how to initialize a matrixer control block. This section will describe each of the matrixer controls in it. (Please refer
to Figure 9.1.)
DSPI: (Master matrixers only.) The Data Signal Presence Indicator is an LED on the front panel of all matrixers.
However, the DSPI control is only available for master matrixers.
The DSPI on master matrixers functions like other IQ components—it flashes whenever a data signal, addressed
to it, is received. It can be forced to stay on as an aid to troubleshooting by turning the DSPI control on. Turning
off the DSPI control restores the indicator to its normal function of blinking when a valid IQ command is received by
the master matrixer.
Tip: Use the DSPI light to verify that all units in the system are responding to IQ commands. For example, turn
all DSPI lights on before a show to verify that all equipment is operating properly.
Tip: When there is more than one matrixer in a system, use the DSPI light to quickly identify a particular one.
For example, turn the DSPI light on to help a technician quickly locate a particular unit in a large equipment rack.
Aux: (Master matrixers only.) Toggles the master matrixer’s AUX port output on and off.
The AUX port also has the ability to sense the presence of an external signal. When a logic “high” is detected at
the AUX connector, an asterisk (*) will appear beside it.
Relay On/Off Controls: Each individual relay can be turned on and off from the control block by highlight-
ing its number and toggling it with the “Space Bar”. MRX-24 and MRX-24S models each have 24 relays. MRX-
12 and MRX-12S models each have 12 relays. Depending on the model, either four or two groups with six relays
each are displayed.
Note: The groups of six relays correspond to the way the relays are physically grouped on MRX-24 and MRX-
24S models. They are arbitrary and can be ignored for MRX-12 and MRX-12S models which have no physical
groups.
All On/Off: Global “All” on/off controls are provided to turn each MRX-24 or MRX-24S group of six relays on
and off as a unit, thereby turning off the group’s bus. However, since MRX-12 and MRX-12S matrixers do not
have physical groups, the All On/Off controls serve to simply turn on/off the first six and second six relays.
