Introduction
Thank you for selecting a Vaux Lattis Matrix Switcher. These systems have been designed for the utmost in
performance and reliability. There are currently four models in the Lattis Matrix Switcher family:
LE-800A 8-source by 8-zone, audio-only LE-800AV 8-source by 8-zone, audio/video
LE-1600A 16-source by 16-zone, audio-only LE-1600V 16-source by 16-zone, video-only
The LE-800A, LE-800AV, and LE-1600A systems provides high-fidelity stereo line-level switching, zoned
volume/bass/treble/muting, programmable min/max/mute/initial-volumes, and other customizable features. The
systems may be controlled using infrared remote controls, keypads, and/or RS-232 serial control from a computer or
other control system (e.g. AMX, Crestron…). The source inputs are driven from any line-level source, while the
volume-controlled zone outputs connect to power amplifiers for each stereo zone. In the case of the LE-800AV and
LE-1600V, the video switching is line-level composite video, for NTSC or PAL systems.
Matrix Switching and Zone Expansion
The Lattis Matrix Switcher is a multi-source/multi-zone audio (or audio/video) distribution and control system. A
Lattis system allows multiple audio (or audio/video) sources to be routed to multiple zones (one or more rooms).
Each zone of the system has independent control over source-selection, volume/bass/treble levels, muting, etc.
Multiple Lattis Matrix Switchers may be combined to expand the number of zones. For example, three 16x16 Lattis
LE-1600A switchers may be use to provide a 16-source by 48-zone system. The units are simply programmed to
respond to different “Base-Zones,” (1, 17, and 33) allowing contiguous zone numbers from 1 to 48. A Vaux system
may expand this way to a total of 255 zones. The audio sources may simply use “Y-cables” to split to two or three
Lattis inputs, or a “Distribution-Amp” (DA) may be used to buffer each source for driving multiple Lattis Matrix
Switchers. For video sources (when using a Lattis LE-800AV or LE-1600V), a DA is not needed since each source
has a buffered output which is used to connect to the video input of the next switcher. With video signals, a Y-cable
cannot be used since it is mandatory to maintain proper 75-ohm video line impedance. You may also mix and match
Lattis switchers to provide different features. For example, an 8x8 audio-only LE-800A may be combined with an
8x8 audio/video LE-800AV, providing eight sources by sixteen zones (eight of these zones have video).
IR and RF Remote Control and Keypad Operation
Lattis Matrix Switchers may be operated by hand-held Vaux RC-16-IR infrared (IR) remote controls. When used
with an optional RC-RFX1 receiver, the Lattis models may also be operated using a radio-frequency (RF) remote,
the RC-16-RF. The remote controls allow selection of A/V source, adjustment of each zone’s Volume/Bass/Treble
levels, as well as system setup and programming functions. The Vaux RC-16 remote control is easily programmed
to control one specific numbered zone – the remote’s zone number may easily be changed to move the remote to a
different room. IR control from multiple rooms will require a wired or wireless IR-Repeater system, which uses IR
sensors in each room. The Vaux RC-16-IR remote may also be used to teach the Vaux control codes (for one zone)
to a third-party hand-held “learning” remote. Vaux programmable keypad systems may also be used to control Lattis
switchers. Additionally, third-party IR-learning keypads may also be employed, using a Vaux RC-16-IR remote to
teach the Lattis commands to the keypad.
Computer Control Systems
The Lattis Matrix Switcher may be completely controlled by an attached computer, or other control system (such as
AMX or Crestron) which communicates over a serial, RS-232 connection. The host computer has complete control
over A/V zone switching, volume/bass/treble levels for each zone, etc. The Lattis system sends messages to the
control system confirming actions for not only RS-232 commands, but also for RF-, IR-, or keypad-generated
commands, closing the loop on the whole system. The control system may optionally poll periodically for system
status, or may simply ignore messages for a basic command-only interface. Serial communication uses the
VauxProtocol standard, presented later in this manual.

Installation
The Lattis Matrix Switcher is quite flexible, in that it can integrate with a variety of A/V devices and control
systems, and may be configured a variety of ways. Installation of the Lattis System is described below:
1. System Power: Place the Lattis Matrix Switcher near your audio/video components. Turn off the Lattis
front panel switch and plug the AC power adapter’s cable into the rear panel Power connector on the
Lattis Matrix Switcher. Plug the adapter into a standard electrical outlet — select an outlet which is not
controlled by a wall switch.
2. Optional Connection of Vaux Wired Keypads: If you are installing Vaux wired keypads, plug the Vaux
Data cable from the keypad connecting hub into the specified connector.
3. Optional IR Input from Repeater Systems, Keypads, or other modulated IR input source: Connect to the
rear-panel IR-In jack, or affix an IR emitter over the front-panel sensor.
4. Optional RS-232 Computer or Control System Connection: Connect your computer or control system,
using a properly wired RS-232 cable, to the 9-pin VC-232 connector on the rear panel of Lattis Matrix
Switcher System. For more information on the VC-232 interface, refer to a later manual section.
5. Connection of A/V Source components: Plug your Audio/Video source components into the Lattis
Source inputs using appropriate cabling.
Note: Lattis Video Switchers (LE-800AV and LE-1600V) use a dual-port connector for source inputs.
The video input signal connects to the black phono jack on the Source side – the yellow phono jack
above this connector provides a 75-ohm buffered output for looping the source to other destinations
(such as a second switcher).
6. Connection of A/V Zone amplifiers: Connect the Lattis Zone audio outputs to power amplifiers
appropriate for each zone. For video-capable switchers, connect the video outputs to video monitors,
or, for longer runs, to composite buffer amplifiers or video modulators. Run the speaker wiring and
video cables to each zone. NOTE: Do not use level-sensing audio amp powering options — low
volumes may turn the amp off.
Note: Lattis Video Switchers (LE-800AV and LE-1600V) use a dual-port connector zone outputs.
Each Zone output has two independent 75-ohm buffered output ports, allowing connection of two video
cables to different destinations.
7. Power-up the system: Turn on the Lattis Matrix Switcher using the front-panel switch — a string of
front-panel lights indicates that the Switcher is running.
10. Install Two (2) “AA” batteries in the RC-16 remote control(s) ( alkaline preferred).

9
RC-16 Remote Control
• The RC-16 Remote Control has four lighted "Mode" keys, which select one of four operating modes.
Pressing a mode button will flash the light twice and change the "Current-Mode." When non-mode buttons
are pressed on the remote, the appropriate mode light flashes to confirm the button press, as well as the
Current-Mode in use. The remote acts as four totally-different remotes in each of these modes.
• A/V is the normal mode for turning a zone on or off, selecting sources, and adjusting volume in a zone. The
remote's "Current-A/V-Zone" may be changed to correspond to the room in which the remote is located (up
to 90 zones and 8 clusters may be controlled). You may select 8 or 16 sources for the zone, depending on
your system.
• Note that some RC-16 buttons are not used with Vaux Lattis switchers -- for Vaux Aris systems, you may
also use the RC-16 to control source equipment using learned IR codes (play, pause, channel, digits...).
• Macro mode is not used with Lattis switchers (Aris-only).
• Lights mode is not used with Lattis switchers (Aris-only).
• Aux mode is for future use.
• Some other buttons will always switch the remote to a/v mode (regardless of the mode it was set to
previously): zone, on/off, volume, mute, shift, prog, and source-select (tuner, cd...).
• During operation or programming, pressing an incorrect button will result in an "Error" flash -- this is a
flash of all four of the lighted mode buttons on the remote (a/v, macro, lights, & aux).
• The RC-16 Remote Control uses two "AA" alkaline batteries. Battery life is typically one year, but will
depend on how frequently the remote is used. When the remote's operating range seems shorter, or
operation seems intermittent or erratic, the batteries likely need to be changed. Batteries contain nasty stuff
which gets released in landfills -- to keep our groundwater clean, please dispose of used batteries at a
recycling center.
• When inserting batteries, all four mode lights flash, indicating that the stored parameters have been restored
to Factory-Settings:
Current-A/V-Source 01 (tuner)
Current-A/V-Zone 01
Current-Lighting-Device 11 (X-10 address A1)
Current-Aux-Device 01

10
Programming the System
Setting each Zone’s Initial Volume Level (and maximum level)
When you have the system running, you will likely wish to tailor each room’s initial volume level (the level to which
it first turns on). You can also set the maximum volume of the amplifier at this point.
Note: The earlier RC-8-IR remote control may also be used to set this adjustment.
• Set the RC-16 remote control so you are controlling the desired zone (01 to 90).
Press the Zone button, followed by two-digits corresponding to the desired zone.
eg: Zone-0-1 will select zone 01, and Zone-1-2 will select zone 12.
This zone is saved in the remote until you change it again.
• Turn down power amp’s level control for this zone to about 25%
• Select a nominal-level source such as a CD or Tuner.
• Using the RC-16 remote control, turn the zone’s volume up to maximum.
• Adjust the power amp’s level control to the loudest level you wish the zone to reach.
• Using the RC-16 remote, turn the volume down to the desired initial (turn-on) level.
• Press Shift-FFwd on the RC-16 (Shift followed by the FFwd key).
• Repeat for other zones.

11

Audio/Video Operation
For all operations below, change the RC-16 remote control to the desired zone, if needed. The remote also needs to
be in a/v mode for the following operations: press the RC-16's a/v mode button to change to a/v mode (the button
will flash twice). Note: the remote is automatically placed in a/v mode when you press certain buttons.
Setting the RC-16’s Current-A/V-Zone:
• For all operations below, set the RC-16 remote so you are controlling the desired zone (01 to 90). Press the
Zone button, followed by two-digits corresponding to the desired zone -- eg: Zone-0-1 will select zone 01,
and Zone-1-2 will select zone 12. This zone is saved until you change it again.
• You may also control a Cluster (a group of multiple zones that is programmed into the Lattis system), by
selecting zones 91 to 98, for Clusters 1 to 8. Only certain functions are available during Cluster operation.
• You may also choose zone 00, which is a special All-Zones code. Only certain functions are available
during All-Zones operation.
• Note: the remote is automatically placed in a/v mode when you press the zone button.
Selecting a Source:
• Press an RC-16 Source button (Tuner, CD...)
Note: This will automatically place the remote in A/V mode.
• The Lattis Ack light will flash. The source is routed to the zone at the programmed Initial-Volume-Level
for the zone (or, the Previous-Volume, if the zone is so configured). If the zone is currently on, the new
source will be at the current volume level.
• The Lattis Active light will be on when any zone is in use.
• If the Lattis s Nak light flashes, the requested zone is not valid for this Lattis unit. (eg: selecting zone 09
when only 01 to 08 are valid in an 8x8 switcher).
• If you have a 16-source LE-1600A or LE-1600V, you access the upper sources by pressing the hift button,
followed by a source button:

Turning the Zone Off:
• Press the RC-16’s On/Off button -- the Lattis Ack light flashes, and the zone turns off (note: pressing the
On/Off button again turns the zone on with the previous source).
• If the Lattis Nak light flashes, the requested zone is not valid for this Lattis unit.

13
Adjusting Zone Volume and Muting:
• Press the RC-16’s Volume-Up/Down buttons, and release at desired volume level.
Note: This will automatically place the remote in A/V mode.
• Press the RC-16’s Mute button -- the zone volume lowers to the programmed Mute-Volume-Level for the
zone. Pressing Mute again will restore original volume.
• The Lattis Ack light flashes during volume adjust or mute. If the Lattis Nak light flashes, the requested
zone is not valid for this Lattis unit, or the zone is not currently on.
Adjusting Zone Bass/Treble:
• Press the RC-16 Shift button, and then press a Channel-Up/Down button to adjust Bass, or a Volume-
Up/Down button to adjust Treble. Each Shift-button-press adjusts up or down one step (can not press-and-
hold for Bass/Treble adjustment)
• The Lattis Ack light flashes as the level is adjusted. If the Lattis Nak light flashes, the requested zone is not
valid for this Lattis unit, or the zone is not currently on.
• You may restore Flat Bass/Treble (both to 0-dB) by pressing hift-Rew on the RC-16.

14
VauxProtocol Commands & Messages (RS-232)
Connection of a computer or control system to the VC-232 serial port allows you to fully control the system using a
selection of Commands, and to obtain immediate feedback on system status by listening to Messages. This
Command/Message language is called VauxProtocol.
VauxProtocol Commands begin with an asterisk (*), followed by two letters, then one or more comma-delimited
decimal number parameters, and finally a carriage-return and/or line-feed char (CR/LF). The numbers are ascii-
encoded-decimal number strings which may range from 0 to 255. The decimal numbers may be one, two, or three
digits total, and may include leading zeroes, or not, as desired (ie: 001, 01, and 1, are all equivalent).
A comma must be used to delimit fields, and the command requires a CR, LF, or CR/LF as termination delimiter --
indicated by <cr>. Spaces may be removed, or inserted if desired (they are ignored).
Note: the following commands are all identical:
*CW,035,007 <cr>
or: * C W, 035 , 007 <cr> (extra spaces are ignored)
or: *CW,35,7 <cr> (leading zeros also optional)
Similarly, VauxProtocol Messages begin with an exclamation (!), followed by one letter, and then one or more
comma-delimited decimal number parameters, and a terminating CR/LF.
The CR/LF characters are the only non-printable ascii characters used in VauxProtocol (CR = 0D hex = 13 decimal;
LF = 0A hex = 10 decimal)).
Coding Tip: You will likely only need to implement a handful of commands/messages in a typical application! The
simplest application will simply send a subset of the commands, and ignore any received Status Messages.
Coding Tip: Status messages are sent in response to RS-232, remote-control, or keypad control – by parsing the
messages independently of the command programming, and updating internal variables in your program, you will
“close-the-loop” on the whole system. You may then send commands blindly, and allow you message-handler to
update your variables/displays. If you wish to ensure that your command resulted in an action, you may monitor
internal variables after sending your command (instead of waiting for the actual message), and implement
timeout/retry/alert code as desired for your application. This is a more generalized technique than simply sending a
command and then waiting to parse a general command-acknowledge message.

15
Control-Command & Status-Message Summary:
• For zones 1 to 255, Status-Messages are sent in response to Control-Commands.
• Many commands return the same status message – simplifying message parsing programming.
• For zone 0 (all zones), no messages returned (multiple switchers would be responding together).
• Note that volume/bass/treble/mute commands will only affect zones that are not off, even if the requested
zone is 0.
• A muted zone will be unmuted if 1) certain route commands (*CW,10/11/12/13/15/17/19) are received, or
2) certain volume commands (*CW,24/25/35/36) are received.

Routing Notes:
Routing audio using standard route commands (*CW,10/11/13,zon...):
1) Routing a source when zone is currently off:
- Routes and sets zone volume to:
a) Normal (factory setting) route volume uses programmed "Zone-Initial-Volume."
b) Optionally, may configure route volume to be "Previous" volume.
(this was level when zone was last turned off)
(the implementation actually updates Zone-Initial-Volume at every zone turn-off).
2) Routing a source when zone is currently on (skipped if source is the same):
- Routes at current zone volume.
3) Routing a source when zone is currently muted:
- Routes and unmutes to previous volume (level when zone was muted).

16
Routing audio using Route-Audio-Muted command (*CW,14,zon,ssa):
1) Routing a source when zone is currently off:
- Routes and places zone in muted state, and sets unmute volume to:.
a) Normal (factory setting) unmute level uses programmed "Zone-Initial-Volume."
b) Optionally, may configure unmute level to be "Previous" volume.
(this was level when zone was last turned off)
(the implementation actually updates Zone-Initial-Volume at every zone turn-off,
then this route-muted command loads unmute levels from initial).
2) Routing a source when zone is currently on (skipped if source is the same):
- Routes at current zone volume.
NOTE: DOES NOT MUTE IF ZONE IS ON
3) Routing a source when zone is currently muted:
- Routes and leaves zone in muted state.
- Unmute level will be previous volume (level when zone was muted).
Routing audio using Route-Audio-At-Volume command (*CW,15,zon,ssa,vvl,vvr):
1) Routing a source when zone is currently off:
- Routes and sets zone volume to specified volume level.
2) Routing a source when zone is currently on:
- Routes at specified volume level (if source is the same, just updates volume).
3) Routing a source when zone is currently muted:
- Routes and unmutes to specified volume level.
Routing audio using Route-Audio-At-Vol-Muted command (*CW,16,zon,ssa,vvl,vvr):
1) Routing a source when zone is currently off:
- Routes and places zone in muted state.
- Unmute level will be specified volume level.
2) Routing a source when zone is currently on:
- Routes at specified volume level (if source is the same, just updates volume).
NOTE: DOES NOT MUTE IF ZONE IS ON
3) Routing a source when zone is currently muted:
- Routes and leaves zone in muted state.

Remote-Control Equivalent Commands and Messages:
Pressing buttons on Vaux remote controls or keypads initiates actions equivalent to the following VauxProtocol
Commands. Since these actions result in the same Messages being sent (as they would for the equivalent Command),
the control system must only parse one set of Messages. This means that the control system is always up-to-date on
zone-routes, volume-levels, and other system parameters, reegardless of whether they were initiated by a
VauxProtocol command, or by a remote/keypad button press.
