Cleaning the Acrylic Surface
An acrylic surface is a beautiful, lustrous material that is outstanding in
durability and break resistance. With proper care, it will retain its attractive
appearanceformanyyearstocome.Thiscareshouldincludeprecautionsagainst
scratchingorcontactwithobjectsofhightemperaturethatmightmarthesurface.
A few simple precautions will preserve the beauty of the acrylic.
• FIRST be sure the surface to be cleaned is powered off.
• NEVER spray or pour any liquid directly onto the surface.
• TO AVOID scratching these surfaces, use a soft brush or cloth to gently
brushawayanylargerdirtparticles.Alternatelythelargerparticlescanbeblown
from the surface with the use of canned air.
• USE a soft, clean lint free cloth or micro fiber cloth and clean lukewarm
water to clean the surface. For stubborn dirt and stains use a mild, nonabrasive
soap and water mixture with the gentle cleaning cloth. Use only light pressure
when cleaning. Avoid rubbing dirt or grit into the surface. Turn the cloth often
andreplacewithacleanclothfrequently.Drybyblottinggentlywithaclean,dry
cloth.
• AVOID using kleenex, paper towels, sponges or other coarse shop towels,
as these materials may contain abrasives that can scratch acrylic surface.
• DO NOT USE ketones, aromatics, esters, halogens, window cleaning
sprays, alcohol, kitchen scouring compounds, or solvents (such as acetone,
benzene, gasoline, carbon tetrachloride, or thinners).

Introduction
The G-5 Digital Control Surface is the next step in the continuing
evolution of Wheatstone’s proven BRIDGE technology. Designed to
integrate flawlessly with the Wheatstone BRIDGE digital audio network
router, the G-5 control surface allows you to easily create large or small
platform-based systems that are exceptionally user-friendly and flexible.
WheatstoneBRIDGEnetworkcageshouseallI/Oportsandenginecards,
and may be wired in tandem within a single equipment room or intercon-
nected to separate remote locations by means of fiber-optic or CAT-5
cables to provide single wire studio integration schemes.
Once configurated, the system operates entirely independently of
externalcomputers.Configurationitselfisintuitiveandcarriedoutonsite
by means of user-friendly graphic interfaces provided by Wheatstone
desktopsoftware.TheG-5systemalsotakesfulladvantageofWheatstone’s
exclusive VDip configuration software, so that studio functions (like
mutes, fader and timer starts, tally, etc.) are easily accomplished right at
your desktop. Once completed, all settings are retained in non-volatile
storage, allowing the entire system to run independently. Ethernet proto-
col is built in, providing interface with automation, scheduling, and
hardware controllers as you require.

Power Supply
The G-5 control surface is powered by a Wheatstone Model PSU-1
rackmount power supply. This unit occupies two 19” wide rack spaces
(total height 3-1/2”). Convection cooled, it requires ample ventilation
space above and below it.
Note the power supply (supplies)
should be mounted in an equipment
rack within fifteen feet of the control
surface (but no closer than 3 feet).
Avoid locating any high gain equip-
ment (such as phono preamps, tape
recorders,etc.)tooneartherackmount
supplies, to avoid magnetic interfer-
ence into that equipment.
Once the supply is rackmounted, it
shouldbeconnectedtothecontrolsur-
face using the factory supplied cable.
The cable has two different types of
connectorsonit:a5-pinfemaleconnec-

using the failsafe option (two PSU-1 supplies), connect one end of a
power supply cable to either control surface power connector and
connect the other end of the cable to one of the two power supply
connectors. Then use the other cable to connect the second power
supply connector to the remaining control surface power supply
connector.
Note each power supply is fitted with a 3-wire grounded AC cord
that should be plugged into a "clean" AC power source, that is, an AC
sourcethat feedsonly thecontrol roomaudiogear.Thissourceshould
be a separate feed from those powering lighting, air-conditioning, or
any other non-audio machinery. The third pin ground wire of the AC
source should be tied to the central system ground point.
Failsafe Dual Redundant Supply
Wheatstone failsafe power supply systems use two PSU-1 power
supplies for each piece of powered equipment. Though either is
capableofrunningafullloadonitsown,infailsafeoperationbothunits
runin tandem:ifonefails,the othertakesover,assuringuninterrupted
operation.
In order for failsafe systems to perform as designed, always have
BOTH rackmount supplies powered up and connected to their associ-
ated equipment.
Energizing
Assuming the G-5 control surface mainframe is properly placed,
and its PSU-1 power supply (or supplies) correctly rackmounted and
connectedtothecontrolsurface,youmaynowenergizetherackmount
power supply by plugging it into the AC mains. The “GOOD” LEDs
onthepowersupplyfrontpanelshouldlightuptoindicatethepresence
of their respective voltages. The control surface's LED meters will

Note: To de-energize the control surface, unplug the rackmount
power supply’s AC cord from the AC mains. Never de-energize the
control surface by disconnecting the cable that connects the control
surface and power supply together.

The AMP tool insulation dis-
placement connector system.
Note the right angle hood with
self-locking tabs. The tool,
multipin connectors (with gold
plated pins) and latching
hoods are supplied with each
control surface.
I/O Connections
All user wiring to and from the G-5 control surface is made via
connectors located on the control surface’s rear panel. Two 5-pin male
connectors at the left end of the control surface’s rear are for power supply
connections. A cue speaker plugs into the female DB-9 connector, located
next to power supply connectors. VGA connections are made via the female
DB-15 connector that is mounted below the cue speaker connector. The
female DB-9 connector at the left end of the control surface’s rear connects
to the internal cue speaker and headphone jack. There are also two RJ-45
connectors for main and failsafe ethernet connections There are also two
female DB-9 serial port connectors for use as RS-485/RS-232 communi-
cation links to the Wheatstone Bridge Router and XY controllers. CAT-5
or multi-mode optical fiber Mixer Link connections are made via RJ-45 or
SC type optical connectors. For all wiring pinout connections refer to
Chapter 5. Sketches below show connector locations.
The Insulation Displacement Connector System
The I/O wiring interface system is based on insulation displacement
technology. A special AMP wiring tool is included with each control
surface; it is auto-indexing, and allows individual wire connections to be

positively made with a single squeeze of the tool's trigger. The trigger
action is ratchet controlled, and will not release until a full connection
is made. Once released, the multipin connector held in the tool's jaw
automatically indexes to the next connector pin. The technology is such
that no stripping, soldering or tinning of wire ends is required; all that
is needed is that the wires destined for the connector be snub cut and laid
out in order (although tubing should be used on bare drain wires). An
empty DB-9 connector is inserted into the tool, indexed to the first pin,
and the wires are inserted one by one into the jaw and the trigger
squeezed. In this way a single multipin connector can be completely
wired up in a minute or two. These connectors will accept wire gauge
22 - 26 AWG.
In the event of a wiring error, connector pins may easily be removed
from the shell with the wire still attached, and inserted into the correct
position. Observe the side of the connector, with the metal part down.
You will see a row of "Vees"—simply press the top of the vee together
with a scribe or other sharp instrument; this will unlock the pin from the
shell, and it can be removed and inserted into the correct position.
Spread the vee apart to lock the pin in the new position. It should never
be necessary to discard a connector due to a wiring error.
Note that mating hoods for each connector are also supplied with
the system. These have locking screws that hold the connectors
securely to their mates.

Wiring Procedure - Double Connection to One Pin
ref: DB-25 male multi-pin connector
Most audio equipment machine interfaces (as well as Wheatstone consoles) use
subminiature D-type connectors. Sometimes the interfaces require making two connec-
tions to a single DB pin. If the wiring has been set up using punchblocks, this is not a
problem; however, for situations where direct machine-to-console wiring is used, Wheat-
stone recommends the following procedure:
1) Connect the first wire to the desired pin as you normally would.
2) Note connector pins may easily be removed from the DB-25 shell with the wire still
attached: Hold the connector with the metal part down and observe its side. You
will see a row of "Vees"—simply press the top of the selected vee together with a
scribe or other sharp instrument; this will unlock the pin from the shell, allowing
it to be removed.
3) With the pin removed, strip out a short section of insulation from the connected
wire and wrap and solder the second wire to the first as shown above.
4) A short piece of heatshrink tubing (pictured here before being slid into place)
completes the connection.
5) Re-insert the pin into the DB-25 shell, spreading the vee apart to lock it in place.
