IM PO RTANT SA FE TY I NF ORMATIO N

1. Save the carton and packing material even if the equipment has
arrived in good condition. Should you ever need to ship the unit, use
only the original factory packing.

2. Read all documentation before operating your equipment. Retain
all documentation for future reference.

3. Follow all instructions printed on unit chassis for proper operation.

4. Do not spill water or other liquids into or on the unit, or operate
the unit while standing in liquid.

5. Make sure power outlets conform to the power requirements listed
on the back of the unit.

6. Do not use the unit if the electrical power cord is frayed or broken.
The power supply cords should be routed so that they are not likely
to be walked on or pinched by items placed upon or against them,
paying particular attention to cords and plugs, convenience
receptacles, and the point where they exit from the appliance.

7. Always operate the unit with the AC ground wire connected to the
electrical system ground. Precautions should be taken so that the
means of grounding of a piece of equipment is not defeated.

8. Mains voltage must be correct and the same as that printed on the
rear of the unit. Damage caused by connection to improper AC voltage
is not covered by any warranty.

9. Have gain controls on amplifiers turned down during power-up
to prevent speaker damage if there are high signal levels at the inputs.

10 Power down & disconnect units from mains voltage before making
connections.

11. Never hold a power switch in the “ON” position if it won’t stay
there itself!

12. Do not use the unit near stoves, heat registers, radiators, or other heat
producing devices.

13. Do not block fan intake or exhaust ports. Do not operate equipment
on a surface or in an environment which may impede the normal flow
of air around the unit, such as a bed, rug, weathersheet, carpet,
or completely enclosed rack. If the unit is used in an extremely dusty
or smoky environment, the unit should be periodically “blown free”
of foreign matter.

14. Do not remove the cover. Removing the cover will expose you
to potentially dangerous voltages. There are no user serviceable
parts inside.

15. Do not drive the inputs with a signal level greater than that required
to drive equipment to full output.

16. Do not connect the inputs / outputs of amplifiers or consoles to any
other voltage source, such as a battery, mains source, or power supply,
regardless of whether the amplifier or console is turned on or off.

17. Do not run the output of any amplifier channel back into another
channel’s input. Do not parallel- or series-connect an amplifier output
with any other amplifier output. Australian Monitor Inc is not
responsible for damage to loudspeakers for any reason.

18. Do not ground any red (“hot”) terminal. Never connect a “hot” (red)
output to ground or to another “hot” (red) output!

19. Non-use periods. The power cord of equipment should be unplugged
from the outlet when left unused for a long period of time.

20. Service Information Equipment should be serviced by qualified service
personnel when:

A. The power supply cord or the plug has been damaged.

B. Objects have fallen, or liquid has been spilled into the equipment

C. The equipment has been exposed to rain

D. The equipment does not appear to operate normally, or exhibits a marked
change in performance

E. The equipment has been dropped, or the enclosure damaged.

This symbol is intended to alert the user to the presence
of uninsulated “dangerous voltage” within the products
enclosure that may be of sufficient magnitude to constitute
a risk of electric shock to persons.

This symbol is intended to alert the user to the presence
of important operational and maintenance (servicing)
instructions in the literature accompanying the appliance.

To prevent electric shock do not use this (polarised) plug
with an extension cord, receptacle or other outlet unless
the blades can be fully inserted to prevent blade exposure.
To prevent electric shock, match wide blade of plug to wide
slot, fully insert.

provided for each destination output. A 7 segment
LED display will indicate the input source number
assigned to a destination output. Any input source
can be assigned to any number of destination
outputs

RS232

The AMAV switcher can be controlled via the RS232 serial control port to
allow for interfacing to a PC, Crestron or similar third party control system.

The serial communication parameters are 9600 baud, 8 bit, No Parity and 1
stop bit – this is often referred to as 9600 8N1. When the unit recognises
a complete command it will perform the requested action – there is no
delimiter character required.

The unit does not send out a message when a value is changed from the
front panel or by IR control. If the unit needs to be controlled from the front
panel in addition to the RS232 control, you would need to regularly poll the
units’ status to ensure the control system accurately reflected the current
settings.

COMMANDS

To Switch Inputs to Outputs

SBIøXOøY Where X is Output Number (1-4) and Y is Input

Number (1-4)

Unit will respond with

SBUDøXOY Where X is Output Number (1-4) and Y is Input

Number (1-4)

Example : Send Input 1 to Output 4

SBIø1Oø4 - Send
SBUDø1O4 - Rcvd

STANDBY MODE

Note : Turning the unit System Power Off over RS232 will blank
the displays leaving only the Power Switch LED on. Hard
resetting the unit when in System Power Off mode will return the
unit to normal operation and unlock the front panel.

Even while the unit is turned off by RS232 it will continue to accept and act
upon switching commands. This allows you to set up a ‘scene’ before soft
powering on the unit and enabling the video outputs. The unit will still return
status and change messages in response to commands sent while in System
Power Off mode.

SBSYSMON - Put system into Standby (Soft Power Off)
SBSYSMOF - Bring unit out of Standby (Soft Power On)

Unit will respond with

SBALOFAK - Unit is in Standby
SBALONAK - Unit is no longer in Standby

Example : Put Unit in Standby (Soft Power)

SBSYSMOF - Send
SBALOFAK - Rcvd

FRONT PANEL LOCK

Note : Hard resetting the unit will unlock the Front Panel controls.
.

SBSYSMLK - When front panel is locked, changes can only be

made by RS232

SBSYSMUK - Front Panel Unlock

Unit will respond with

SBSYSLOK - Front Panel has been Locked
SBSYSULK - Front Panel has been Unlocked

Example : Lock Front Panel Buttons

SBSYSMLK - Send
SBSYSLOK - Rcvd

UNIT RESET

SBSYSMLK - Reset every output to Input 1

Unit will respond with

SBRSTACK - Unit has reset each Output to Input 1

Example : Reset all outputs to Input 1

Before making any connections to the VGA44, observe the
following:

> Before making any connections to the VGA44, observe the following:

> Ensure the mains voltage supply matches the label on the supplied
plug-pack (+/- 10%)

> Ensure that the power switch is OFF

> Ensure that all system grounds (earth) are connected to a common point.
Avoid powering equipment within a system from multiple power sources that
may be separated by large distances

OPERATION

> Connect all audio video sources and destination equipment

> Power up all source and destination audio-visual sources

> Power up the VGA44 VGA matrix switcher

> For each destination output select the appropriate input source by using
the front panel UP and DOWN select button, the supplied IR remote control,
or through the RS232 serial communications port

REMOTE CONTROL

The AMAV VGA44 matrix switcher ships with a remote control. The
remote control has the following functionality:

i) Source Select Buttons
Four separate input assignment buttons are provided for each of the
four VGA outputs. The last selected input source will be routed to
the destination output. Input sources may be assigned to multiple
destination outputs

ii) Power Button
Toggles the unit into, and out of, standby mode. In standby mode the
matrix switcher will stop video routing. Standby mode is indicated by
the illumination of the front panel power LED only.
