Pre-Installation Checklist

The Audio 8x8 Matrix Switch provides a centralized switching center via UTP cables.

1. The Matrix Switch is used in conjunction with MuxLab hi-fi analog balun

(500028) and digital balun (500020).

2. The Matrix Switch is typically installed in a remote telecom room and is connected

to multiple video sources and display devices via Cat 5e/6 UTP. A MuxLab balun

is installed at each receiver/amplifier/audio source to support the connection to the

Matrix Switch via a Cat 5e/6 cable.

Physical Installation

MuxLab’s Audio 8x8 Matrix Switch comes with mounting brackets for standard 19”

rack mounting. Select the final destination for the product and install the unit using

standard rack-mount screws (Figure 4).

Figure 4: Setup for Rackmount Installation

For set-top installation, the side mounting brackets may be removed, and the included

rubber feet placed on the bottom of the unit. When removing the mounting brackets,

be careful to keep and reinstall the four screws on each side of the unit (Figure 5).

3. Connect all sources and outputs to the Matrix Switch.

4. Connect the external 12 VDC power supply to the Matrix Switch and plug the

power supply into an AC power outlet.

5. Power up all equipment.

6. Figures 6 and 7 show some typical configurations.

The Matrix Switch is now ready to use. See Section 3.7 Manual Control for

instructions on usage.

Manual Control of Matrix Switch

The Audio 8x8 Matrix Switch may be manually controlled by using pushbuttons on its

front panel (Figure 8). It can also be controlled remotely via a keyboard.

Figure 8: Front Panel Display Screen and Controls

There is one display screen and five controls pushbuttons on the front panel of the

Matrix Switch. The display screen is a blue LCD screen that presents the user with

menus for controlling the Matrix Switch. Of the five control pushbuttons, four are

navigation controls (Up, Down, Left, Right) arranged in a lozenge formation that

enable the user to navigate the menus shown on the LCD screen. The fifth control

pushbutton, a large square labeled Enter, allows the user to select the current entry

shown on the LCD screen.

Upon powering up, the LCD screen displays two lines of text:

8X8 AUDIO MATRIX [Product name]

1.0.0 [Software version]

If no control pushbutton is pressed for 3 seconds, the LCD screen will display all 8

channel connections in sequence:

OUTPUT_CH1 [Name of output channel 1 (or default name)]

INPUT_CH1 [Name of input connected to output channel ,

NO INPUT or TEST TONE]

If any control pushbutton is pressed, the LCD screen will switch to Parameters mode

and display the following:

MAIN FUNCTION:

SELECT INPUT CHANNEL

By pressing the Up or Down control pushbuttons, the LCD screen will switch to

Parameters mode and display the following menu sub-options:

MAIN FUNCTION:

MONITOR CHANNEL

or

Remote Control of Matrix Switch

The Matrix Switch can be controlled by a remote (not included). For a list of IR codes,

refer to Appendix C.

Cascadability

Two Audio 8x8 Matrix Switches can be cascaded using the expansion port (Figure 9)

on the back panel of each unit. To cascade two units, one unit must be configured as

the master and the other as the slave, which is done via the internal jumper P4 pin 1-2.

Figure 9: Expansion Port (Back Panel)

Figures 10 and 11 illustrate two possible configurations for cascading two Audio 8x8

Matrix Switches.

Port Control Operation

MuxLab 4x4 Matrix Switch, HDBT may be controlled in the following two ways:

1. RS-232 Control

2. USB CDC Control

1. RS-232 Control

The Matrix Switch features built-in firmware that allows commands from an ASCII

terminal to be sent directly to the device via an RS-232 connection. Ensure that the

RS-232 cable has the straight-through configuration shown in Figure 12.

Figure 12: RS-232 Cable Configuration

Please note that the use of USB to RS232 converter cables may result in problems,

depending on the quality of the converters.

2. USB CDC Control

Commands from an ASCII terminal may also be sent directly to the device via a USB

connection. Maintenance can be performed with a terminal emulator, such as the one

available under windows with the ASCII Command set described in the Appendix of

this manual.

USB Driver Setup

When interfacing a MuxLab device with the USB port on Windows XP, Windows 7,

or Windows 8 operating systems, a driver setup file will be required. For Linux and

Mac OS X operating systems, no driver is necessary.

To install the USB serial driver, download the SC-000032-A USB to serial driver file

from the MuxLab website and save it to the local hard drive. NOTE: If the

downloaded file is compressed, it will have to be uncompressed before using it.

Plug the USB cable between the device and the PC, and power up the device. The

Found New Hardware wizard will open (Figure 13). Select Locate and install

driver software (recommended).

Figure 13: Found New Hardware Wizard

Page 19

A new dialog box will open (Figure 14). Select Browse my computer for driver

software (advanced).

Figure 14: Found New Hardware Dialog Box

Another dialog box will open (Figure 15). Click Browse and locate the SC-000032-A

USB to serial driver file downloaded earlier. Once found, click Next.

Figure 15: Browsing for Unknown Device

Page 20

A security window will now appear, indicating that the driver software is unsigned

(Figure 16). Select Install this driver software anyway.

Figure 16: Windows Security

A window will appear instructing that the software for the driver has been successfully

installed (Figure 17). Click Close.
