Introduction
The Bridge 2001 Digital Audio Network Router rackmount unit occu-
pies four 19” wide rack (total height 7”) with 16” depth.
The 2001 is a unit that can take up to 512 discrete analog and digital audio
inputs in Audio Engineering Society (AES) format, and switch them to any
of 512 separate outputs. The unit’s backplane carries these signals via 32
16xTDM busses. Various input sources place the AES signals onto the
TDM busses, while output cards can select any combination of signals to
take off the TDMs to drive their output channels.
Systems can start small with a single cage and only a few cards; chassis
can be stacked to form a larger central system. Cages can be separated by
very long distances with many studios connected to your central rack room,
providing shared resources yet still permitting independently functioning
satellite studios, each with its own combination of analog and digital input
and output cards and connector modules specifically selected to suit a large
variety of gear. Individual 2001 switches may be connected together to form
a “Multi-Tiered” switch. This switch is arranged in a star topology, with a
central Hub switch connected to up to 14 satellite switches. This system
allows as many as 7168 channels of data comprising a maximum of 2048
input signals and 2048 outputs to be switched.

Power Supply
t
GENERAL INFORMATION
The 2001 is powered by an SPS-180, SPS-400 or SPS-40 power
supply installed in a Wheatstone Model PSR rackmount unit. The PSR
unit occupies two 19” wide rack spaces (total height 3-1/2”) and houses
up to four SPS-180 or up to two SPS-400 or SPS-40 power supply units.
Do not mount heat generating devices in the same rack cabinet.
Avoid locating any high gain equipment (such as phono preamps,
tape recorders, etc.) too near the rackmount supplies, to avoid magnetic
interference into that equipment.

SPS-180 unit
This power supply contains high voltage circuits that are hazardous
and potentially harmful. Under no circumstances should the metal
cover be removed! If you have a problem with the power supply, the unit
must be returned to Wheatstone Corporation for repair.
Once the supply is rackmounted, it
should be connected to the 2001 using
the factory supplied cable(s). If the
2001 router is powered by the SPS180 or SPS-400 unit, the power supply

rear of the chassis). If you are using

two supplies (failsafe option), one supply will connect to each 2001 connector; otherwise only one connector will
be used (it does not matter which one).
When the 2001 is powered by the SPS40 unit, there is an additional rear PWI40 module that is mounted next to the
PWIH(PWI)-2001 module. One power
supply cable plugs into either one of the
PWIH(PWI)-2001 module’s power connectors and the second cable plugs into

GENERAL INFORMATION
either one of the PWI-40 module’s power connectors. If you are using
two power supplies (failsafe option) the second power supply will be
plugged into the remaining power connectors on the rear PWIH(PWI)2001 and PWI-40 modules.
Note that the power supply cable’s 10-pin female connector has to
be rotated until its locating pins match the male mating connector on
the rear of the 2001 chassis. Do not force a connector on; it attaches
easily when properly aligned. Connect the cable(s) first to the 2001,
then to the rear of the rackmount power supply.
Note that each power supply is fitted with a 3-wire grounded AC
cord that should be plugged into a "clean" AC power source. This
source should be a separate feed from those powering lighting, airconditioning, 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 SPS-180,
SPS-400 or SPS-40 rackmount power supplies for each piece of
powered equipment. Though either is capable of running a full load on
its own, in failsafe operation both units run in tandem: if one fails, the
other takes over, assuring uninterrupted operation.
In order for failsafe systems to perform as designed, always have
BOTH rackmount supplies powered up and connected to their associated equipment.
The power feed recommended in the text is often installed and referred
to in studios as an “isolated AC ground” outlet.
It is usually orange in
color.
Energizing
Assuming the 2001 and its PSR power supply are correctly
rackmounted, you may now energize the PSR rackmount power supply
by plugging it into the AC mains.
Note: To de-energize the 2001, unplug the rackmount power
supply’s AC cord from the AC mains. Never de-energize the 2001 by
disconnecting the cable that connects the router and power supply
together.

GENERAL INFORMATION
I/O Connections
A family of I/O connector modules plug right into the cage rear to
give you a choice of DB-25 or RJ-45 connections for analog or digital
audio interface, or BNC connectors for use with 75 ohm digital audio
equipment. RJ-45 connectors are also available for use with CAT-5
wiring systems. The DB-9 connectors are used for connections to the
serial interface.
The Insulation Displacement Connector System
The DB-25 and DB-9 I/O wiring interface system is based on
insulation displacement technology. A special AMP wiring tool is
included with each system; 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 for 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-25 or
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.
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

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 console. These have locking screws that hold the connectors
securely to the rear of the router mainframe.
Digital Audio Connections
CABLE - All AES/EBU input and output digital audio connections
are balanced and should be made using a high quality digital audio
cable. Be sure to select a digital audio cable with an integral drain wire
of the same wire gauge (AWG) as the twisted pair as this facilitates an
easier consistent termination process. Typical AES/EBU digital audio
cable has a very low characteristic capacitance per ft (pF/ft), and a
nominal impedance of 110Ω. High quality digital audio cable offers
better signal transmission performance versus typical analog audio
cable, especially over long cable runs. Check the cable manufacturer’s
data sheet to be sure the cable you plan to use will work in your
application.
CONNECTORS - Typically, all AES/EBU connections are made
with the supplied DB-25 male mating connectors. These crimp style
connectors are the insulation displacement type and will accept wire
gauge 24 - 22AWG. If an optional rear panel connector type (e.g. BNC,
RJ-45, etc.) was specified and shipped with your system, please refer
to the mating connector manufacturer's recommendations for termination instructions.
Unbalanced Analog Connections
ANALOG INPUTS — Wire to the router input end with typical
shielded, two conductor cable (like Belden 9451), just as if you were
connecting a balanced source. At the unbalanced source machine’s
output, connect the + output to the HI input wire and connect the source
machine GND wire to LO, connect the shield at one end only .
Note: Unbalanced analog sources typically have -10dBv (316mV
RMS) signal levels and will not match the 2001 nominal operating
level of +4dBu (1.23V RMS). We highly recommended that you first
externally balance any unbalanced sources you plan on connecting to
the 2001. Many third party “match boxes” are commercially available
for this.
ANALOG OUTPUTS — Use a balanced output circuit which
behaves exactly like the secondary of a high-quality transformer, with
no center tap—this output is both balanced and floating. For unbalanced operation, either the HI or LO side of the analog output must be
strapped to ground of the unbalanced input, with the output taken from
the other side. (Normally you would strap LO to ground, and use HI to
feed your unbalanced equipment input.) Leave the SH floating at one
end.

GENERAL INFORMATION
Unbalanced Digital Connections (SPDIF)
SPDIF INPUTS - The SPDIF (Sony/Phillips Digital Interface) or
“consumer” digital audio interface is a two wire unbalanced signal
typically on a single RCA style connector. Note that the SPDIF signal level
of approximately 500mV and 75 ohm impedance does not correctly match
the 2001 AES inputs. We highly recommend using a “balun” or format
converter when interfacing “consumer” grade source devices to the 2001.
In cases where a consumer grade device must be interfaced and the
appropriate matching device is not available, try wiring the SPDIF center
conductor (HOT) to the HI input pin and SPDIF shell (ground) to the LO
input. Connect SH at the 2001 router end only.
SPDIF OUTPUTS - The Bridge 2001 digital outputs are fixed, professional, AES-3 formatted outputs. SPDIF consumer format is not supported. Use an external format converter to connect the digital outputs to
consumer gear.

Chassis / Backplane Overview
The 2001 chassis may be configured to suit a variety of I/O card
complements including—analog or digital audio input and output cards,
chassis expansion and audio network cards. A system may include a single
cage, multiple co-located cages, or a central chassis connected to one or more
satellite frames in a star configuration. All audio input and output signal
connections are made via a family of I/O connector modules that plug into
rear of the chassis. Power supply, serial control, audio network and ethernet
connections are also made on the rear of the chassis.
The backplane itself is entirely connectorized and contains a minimal
number of passive components. Further, the backplane assembly may be
removed rather easily in the rare case that service is required.
page 2 – 42001 / Jul 01
Page 24
HARDWARE
Chassis Configuration Guidelines
While new 2001 systems are pre-configured to customer specifications
at Wheatstone’s factory, future expansion of a system may require some reconfiguration of existing hardware to accommodate new resources.
Audio Slots
Audio I/O cards may be mounted in almost any slot, though there are
some basic guidelines and considerations to take into account when filling
a master or remote chassis. Room for future input and output expansion
should be taken into consideration. Further, it is useful to group input and
output cards by type (e.g. analog inputs, AES outputs, etc.) and to leave a few
blank positions following each group.
Reserved Slots
The master chassis must have a host CPU card installed in slot 22.
Systems requiring Audio Network cards must have them installed beginning
at slot 1 of the master chassis.
Remote racks must also have an Audio Network card installed in slot 1.
Stacking cards used to expand the master chassis should be located as
close to the ends of the chassis backplane as possible. One Stacking card per
chassis is required.
Note: Stacked systems connect up to 4 co-located chassis into a larger virtual
chassis (i.e. a single master chassis and up to three expansion racks).
Backplane T ermination
The high frequency nature of the electrical signals on the backplane
require that active terminator circuits be present at both ends of the chassis
backplane. The backplane assembly has special terminator card slots at each
end of its circuit board.
The master chassis has a terminator card installed at the far left end only.
The right hand termination in a master chassis is performed by the host CPU
circuit board, always installed in slot 22. Multiple CPU systems move right
end termination off the CPU circuit card onto a special terminator board
installed in slot 21.
All other frames require that terminator cards be installed in both the far
left and far right terminator card slots.

Digital Input Card (AES-2024)
Overview
There are two versions of digital audio input cards for the 2001:
• AES-2024/8 card will accept up to 8, AES-3 formatted stereo sources
(i.e. 16 mono channels);
• AES-2024/16 card will accept up to 16, AES-3 formatted stereo sources
(i.e. 32 mono channels);
A Signal Definitions form in the supplied XPoint software allows the
user to set attributes for the input channels including signal name, type,
circuit #, etc. The 16 (32) input channels may be configured as mono signals
(one channel), stereo signals (two channels), or 5.1 surround sound signals
(six channels) wired in any combination. Signals may span across input
cards (e.g. a surround sound signal may have 2 channels on one input card,
and 4 on a different input card).
Note: While it is possible to split the 8 (16) stereo AES inputs into 16 (32)
mono channels, there are still only 8 (16) physical wires, each containing the
2-channel AES formatted data.
A dedicated sample rate converter for each input re-clocks the incoming
audio data and phase locks it to the system’s master sample rate clock.
Embedded logic routes each channel of audio data into an available time slot
of the input card’s TDM bus. One TDM bus is allocated for each 8 input card,
2 TDM’s are used by the 16 input card.
AES Input Interface
The balanced, digital audio inputs on the AES-2024 card are transformer
coupled. AES receivers strip off the received sample rate clock and audio
data for further processing by sample rate converters. The balanced interface
operates at a nominal peak-peak input voltage of +5V with an input
impedance of 110Ω and conforms to the AES-3 1992 electrical specification. Note that Channel Status data is not forwarded.
While unbalanced SPDIF formatted input signals may be connected to
the HI and LO inputs of an AES input channel (leave the shield floating), it
is recommended that a BALUN or other external matching device be
inserted to convert the SPDIF impedance to 110Ω and signal level to at least
1V p-p. Note that the optional BNC rear panel input impedance is internally
fixed at 75Ω.
Internal Programming Options
There are no internal programming options on the AES-2024 input card.

All user wiring to the AES-2024 card takes place at the rear I/O connectors
modules: DB, 2DB, 8BNC or 8RJ-45. The DB module has one female DB-25
connector and 2DB has two DB connectors for audio input connections. The
BNC module contains eight BNC connectors for use with 75 ohm digital audio
equipment, likewise the 8RJ-45 module contains eight RJ-45 connectors for
use in balanced, unshielded twisted pair (UTP) wiring systems.

Analog Input Card (ADI-2001)
Overview
The Analog input cards accept up to 8 stereo analog audio sources (i.e.16
mono channels). A Signal Definitions form in the supplied XPoint software
allows the user to set attributes for the input channel hardware including signal
name, type, circuit #, etc. The 16 input channels may be configured as mono
signals (one channel), stereo signals (two channels), or 5.1 surround sound
signals (six channels) in any combination. Signals may span across input cards
(e.g. a surround sound signal may have 4 channels on one input card, and 2
channels on a different input card).
The balanced, line level analog input signals are buffered and converted to
the digital domain by 24bit A-D converters operating at the system’s master
sample rate. Embedded logic routes each channel of audio data into an
available time slot of the input card’s TDM bus. One TDM bus is allocated for
each input card.
Analog Input Interface
The balanced analog input stages are direct coupled, unity gain circuits and
operate at a nominal input level of +4dBu. The input impedance is 20kΩ. A
+4dBu input signal will result in a -20dBFS digital output level at any of the
selected AES outputs. The maximum analog input signal level is +24 dBu
providing 20 dB of headroom above the nominal input level.
Reference Notes:
0dBu = .7746 V RMS, +4dBu = 1.23V RMS
dBFS = dB Full Scale Digital
-20dBFS = +4dBu
Internal Programming Options
There are no internal programming options on the ADI-2001 card.

Digital Output Card (DO-2001)
Overview
Each Digital Output card provides 8 physical AES-3 formatted outputs.
The eight physical AES outputs are divided into 16 channels or circuits in
software to allow the greatest routing flexibility. A Signal Definitions form
in the supplied XPoint software allows the user to set attributes for the output
channels including signal name, type, circuit #, etc. The 8 AES outputs are
configured in software to be any combination of mono, stereo or 5.1 output
signals. For example, the card is normally configured as 8 stereo outputs, but
might also be configured as, 4 stereo outputs and 8 mono outputs. Many
combinations are possible up to the card’s 16 channel limit. 5.1 signals may
span across two DO-2001 output cards.
Each output card listens for connection commands from the CPU card,
and then uses this information to connect the appropriate sources to their
selected output channels. The selected audio data is fed to AES transmitters
which format the 24 bit audio data according to the AES-3 standard.
Note: While it is possible to split the 8 stereo AES outputs into 16 mono
channels, there are still only 8 physical wires, each containing the 2-channel
AES formatted data.
AES Output Interface
The balanced digital audio outputs on the DO-2001 card are transformer
coupled and exhibit a nominal output impedance of 110Ω. This interface
operates at a nominal output voltage of +5V p-p and conforms to the AES3 1992 electrical specification. The DO-2001 output cards operate at unity
gain and transmit 24bit audio data word lengths at the system sample rate.
Output sample rate is set to 44.1 kHz or 48 kHz via certain settings on the
CPU-2001 card. Optionally, the CPU’s External AES Sync input may be
used to slave the system to a user provided 44.1 kHz or 48 kHz reference rate.
Please refer to the CPU-2001 hardware section for details on external
synchronization.
The digital output signal reference level is -20dBFS. A +4dBu analog
input signal yields a -20dBFS digital output signal. Channel Status implementation complies with rules for “Standard implementation” as described
in the AES-3 1992 specification.

Analog Output Card (AO-2001)
Overview
Each Analog Output card provides 16 physical monaural output channels
. These output channels are configured in software to be any combination of
mono, stereo or 5.1 output signals. A Signal Definitions form in the supplied
XPoint software allows the user to set attributes for the output channels
including signal name, type, circuit #, etc. For example, the card may be
configured as 8 stereo outputs, or, 4 stereo outputs and 8 mono outputs. Many
combinations are possible up to the card’s 16 channel limit. Note that 5.1
signals may span across two AO-2001 output cards.
Each output card listens for connection commands from the CPU card
and then uses this information to connect the appropriate sources to their
selected output channels. The selected audio data is fed to 24 bit, twochannel digital-to-analog converters. D-A converter outputs are buffered by
integrated differential output drivers.
Analog Output Interface
Each balanced, unity gain output will drive loads up to 600Ω and behaves
much like a transformer in that either side of the balanced output may be
grounded. The analog outputs are direct coupled with an output impedance
of 50Ω and a nominal output signal level of +4dBu yielded from an analog
input signal of +4dBu (-20dBFs digital) .
Internal Programming Options
There are no internal programming options on the AO-2001 card.

Host CPU (CPU-2001)
Overview
The host CPU card used in the Bridge 2001 incorporates a PC/104
computer mounted on a backplane interface card (the HC-2001 PCB). The
host computer utilizes RAM, a flash disk (which emulates a standard IDE
hard drive) and an Ethernet port. There is no hard disk drive. Keyboard,
floppy controller and video ports are for factory use only. The host CPU board
must only be present in the “master chassis” of a single tier switch.
The purpose of the CPU card is to provide control of the 2001 system
including the master chassis and any other chassis connected via Stacking or
Audio Network cards. The CPU communicates to the XPoint Configuration
PC and XY Controller GUI’s via TCP/IP over Ethernet, via a backplane
command bus to the other cards in its switch, and via RS-485 serial links to
existing XY Controllers and Wheatstone consoles. The CPU also phase locks
the crosspoint switch and attached remote racks to an on board crystal
oscillator or an external AES “black” reference source.
Hardware and software configuration as well as real time crosspoint
information is saved in non-volatile storage on the CPU card and is restored
at power up or reset. This configuration information provides details to the
host application running on the CPU such as the specific audio hardware
available, serial port allocation, I/O signal names, etc. and may be modified
via the Configuration GUI. Switching information is dynamically controlled
via both hardware based XY Controllers and PC based XY GUI’s. Network
IP address configuration of the CPU is handled by the provided DOS utility
application Networkconfig.exe. System configuration is discussed in detail in
the following sections.
Multi CPU / Failover CPU Systems
Multiple CPU’s may optionally be present in large “Multi-Tier” configurations. For the sake of clarity, a single CPU system is assumed in this
discussion. Please consult the factory for multi-cpu system details. S

CPU-2001 BIOS Settings/Format
BIOS Setup and formatting of the Host CPU is completed prior to the
testing of your 2001 Switch at the Wheatstone factory. There are no user
adjustable settings. Please contact customer support with questions regarding the PC/104 SBC BIOS settings or flash disk formatting.

Ethernet IP Addressing
Wheatstone 2001 digital audio network routers ship with the host CPU IP
address set for 192.168.1.160 and the personal computer’s NIC set for
192.168.1.212. Stand-alone systems (not interfaced to a station’s existing
network) require no IP address changes.
Before the switch will be recognized on your network, you will most likely
need to re-configure the host CPU and XPoint PC’s IP addresses. To change
the host CPU IP address, a utility application, NETWORKCONFIG.EXE,
supplied on the XPoint CD-ROM must be run. See the Appendix 1 for detailed
information.
Ethernet Interface Wiring
Stand-alone systems are defined as a host rack connected to a XPoint
configuration PC and not interfaced to a station’s existing network. Standalone systems are “point to point” configurations and are connected by a CAT5 crossover cable.
Networked systems are defined as a host rack connected directly to an
existing Ethernet network hub. Networked systems are connected to the
network hub via a straight (pin to pin) CAT-5 cable. Typical CAT-5 cable pinouts are included in the “Hook Ups” section near the end of this

DIPSW1-SW4 RS-485 Termination
These four, 4-position dipswitches configure the 485 port termination as
follows:
SW1-SW4
POSITION BIASED TERM PASSIVE TERM UNTERMINATED
1 - TX10Ω
2 - TX+
3 - TX4 - 120Ω
Choices are Unterminated, Normal Termination, or BIAS Termination on
the transmit and receive lines. SW1 and SW2 are for Port A, and SW3 and
SW4 are for Port B. SW1 and SW3 are for the RS-485 transmitter’s
termination on the CPU; SW2 and SW4 are for receiver terminations.
An RS-485 bus may only be BIAS TERMINATED at one end. All
applicable Bridge 2001 OAN and CPU cards are set for BIAS TERMINATION by default. All peripheral devices are set for NO TERMINATION by
default. Set the TERMINATION to ON for the last controller or console only,
in a RS-485 chain.

This momentary pushbutton switch may be used to command transfer
of CPU mastering from one CPU to other in a dual CPU system.
Jumper Settings
J1 - RS-232 GND - default is “OPEN”
J1 is inserted if Port A is to be used as a RS-232 port rather than RS-
485. The jumper shorts DB-9 connector Pin 8 to ground which must be
used for the RS-232 ground reference.
J2 - not used
J3 - not used
J4 - AGND to DGND - default is “CLOSED”
J4 connects Audio Ground to Digital Ground.
J5 - FPGA PGM - momentary shorting will reprogram the FPGA.

Selects 48kHz or 44.1 kHz as Master Fs; derived from onboard crystal
oscillators.
J6 open - 48 kHz
J6 shunted - 44.1 kHz
Serial Interface Ports
Serial ports A and B are typically used to connect remotely located XY
controllers and Wheatstone consoles to the switch via 4-wire RS-485.
These ports are configured from the Xpoint GUI and are setup at the
factory as follows:
PORT A - RS-485, 38400 bps, XY controller port
PORT B - RS-485, 9600 bps, Console port
Note: Serial port A may be setup for RS-232 operation via jumper setting
J1.
*NOTE: When changing the audio sample rate of the Bridge

Audio Network Card
(OAN-2001)
Overview
The Audio Network card is used to connect a master chassis to a remote
chassis via a fiber optic link or CAT-5 cable. Audio Network cards must be
installed in pairs (i.e. an Audio Network card in the master chassis communicates to a companion Audio Network card in the remote chassis). An
Audio Network card selects up to 64 mono channels (32 stereo signals), in
four blocks of 16 channels, for bi-directional transport to the companion
Audio Network card. The companion Audio Network card in turn may place
these channels onto the appropriate number of consecutive remote chassis
TDMs (1-4, depending on the number of channels). The CPU card controls
the configuration of the Audio Network cards (local channels being driven
to the remote Audio Network card / TDMs being driven by the remote Audio
Network card).
Between local and remote racks within a single tier, Audio Network
cards are used to bring data in from and send data out to remote racks. No
provision is made to configure Input and Output cards in a remote chassis
to communicate directly with each other. The remote racks are similar to the
local chassis; with up to 4 TDMs populated per Audio Network card. A
remote chassis cannot be daisy chained to another remote chassis.
In a Multi-Tiered environment, Audio Network cards are used as the
inter-connections between the Hub switch and up to 14 Satellite switches.
These “inter-connect” Audio Network cards must all reside in the local racks
of each tier. In addition, at least one of these inter-connecting Audio
Network cards must reside in the master chassis of each satellite tier (in order
to drive the clock).

Pos.1 - Local/Remote (Clock source)
The Local/Remote setting is required to configure OAN cards such
that a Local card will operate from the backplane clock/sync references.
A Remote card would likewise infer that clock/sync are to be extracted
from Fiber/CAT5 and driven onto backplane.
• The system’s master chassis must have only one LOCAL-PRIMARY
OAN card connected to each companion remote chassis.
• Each remote chassis must have only one REMOTE-PRIMARY
OAN card.
Pos.2 - Secondary/Primary
Some system configurations may have multiple OAN cards in each
rack. The Primary setting is used to distinguish which OAN card will act
as the Clock/Sync master in the Remote chassis. Additional OAN cards
must be set to Secondary. Secondary cards will not transmit/receive
control information since this would duplicate the Primary card.
• The system’s master chassis must have only one LOCAL-PRIMARY
OAN card connected to a companion remote chassis.
• Each remote chassis must have only one REMOTE-PRIMARY
OAN card.
Pos.3 - 48kHz / 44.1kHz*
Selects the system’s sample rate frequency; 48 or 44.1 kHz.
If Y1 and Y2 are populated with surface mount clock oscillators, and
Y3 is not installed (default), then 3 pin jumper posts J3 must be used to
select the correct frequency. A jumper shunt between the center pin and
pin closest to Y1 selects Y1 (48 kHz) and likewise a shunt to pin closest
to Y2 selects Y2 (44.1 kHz).
The clock oscillator on the Audio Network card must match the
system’s master clock frequency. If the system audio sample rate is 48
kHz, then the clock reference must be 24.576 MHz and likewise for 44.1
kHz, a 22.5792 MHz clock is necessary. If only Y3, a DIP socketed clock
is populated and not Y1 or Y2, then the appropriate matching clock
frequency must be installed in Y3.
Pos.4 - Fiber/CAT5
Selects whether the audio network connection to the companion Audio
Network card will be made through either optical fiber or copper CAT-5
cable.
*NOTE: When changing the audio sample rate of the Bridge
2001 Digital Audio Network

Optical Fiber Interface
Connector Type
The OAN audio network card provides a
SC Duplex style connector for interfacing
optical fiber. The SC (subscription channel)
connector is a low insertion loss, locking
mechanism with excellent strain relief characteristics. The following AMP® part number may be used to reference the physical
characteristics of the required mating connector.
AMP SC Duplex connector Kit Part Number: 504657-1
Optical Fiber
The typical optical fiber cable required in this application is a
multimode, glass core cable, with a core/cladding size of 62.5/125
µ
suitable for low-to-moderate-speed data links (≤100Mbps). The fullduplex nature of the audio network interface requires one fiber for
transmit, and one for receive; hence dual zip cables are recommended.
m,
Optical fiber cables are manufactured with a variety of jacket
materials, which directly affect cable cost, including Thermoplastic
Elastomer (TPE), Kynar® and Teflon® FEP. Physical properties of the
jacket material determine a cable’s resistance to abrasions, flame
retardancy, etc. Check local codes to be sure the cable you plan on
using is compliant in your application.

Stacking Card (CEX-2001)
Overview
The Stacking card is used to connect up to 4 co-located racks into a larger
virtual chassis. The stacking approach is most useful when configuring
medium to large centrally located systems which employ a large number of
analog or digital audio I/O cards. Stacked racks allow full physical access to
all 32 TDM busses by expanding the number of available slots. Remember,
a single chassis has 22 slots which can accommodate a maximum of 20 I/O
cards, whereas a four rack stacked system for example has 88 slots. Only one
chassis (the master chassis) may have an active CPU card.
Configuring the Virtual Chassis
Each stacked chassis must have a single
CEX-2001 chassis expansion card installed in
Slot 1. Each CEX-2001 card is chained together
using the provided high density multipin cables,
similar to that used in SCSI interfaces (pinouts are
NOT identical to SCSI). A cable from Rack1 connects to Rack 2, Rack 2 to Rack 3, etc. The supplied
termination plugs must be fitted to the unused
connectors at both ends of the chain.

When configuring stacked systems, attention
must be given to the number of TDM busses allocated to the master chassis and each expansion rack.
The number of TDM busses in a rack determines the
CAGE n
RACK IDn
TERMINATOR
number of input cards allowed in a rack. Each input
card uses one TDM bus.
The 4 position dipswitch SW3 allows the user to allocate TDM busses in
groups of 8, with each switch position allocating 8 TDM busses. The first
position of SW3 on the CEX-2001 in the master chassis must always be ON,
and conversely the first position of SW3 on the remaining CEX-2001 cards
installed in the expansion racks must always be OFF. How you set the
remaining 3 positions of dipswitch SW3 on each CEX-2001 card determines
how many TDM busses are available to each rack. For example, assume a 2
rack system: switch ON SW3, positions 1 & 2 on the master rack CEX-2001
and SW3, positions 3 & 4 on the second rack’s CEX-2001 card. The master
rack and the expansion rack now each drive 16 TDM’s, giving each rack the
ability to house up to 16 input cards each.

OPEN=SOCKET
CEX-2001 Rack ID
The CEX -2001 Rack ID numbering scheme differs significantly from the
methods used on OAN-2001 and CPU-2001 circuit boards. Stacked racks
have Rack ID’s of 1 through 4 inclusive. The Rack ID numbers for stacked
frames are a by-product of the TDM assignment dipswitch setting described
in the previous section. Each position, 1-4, of the four position dipswitch SW3
also corresponds to Rack ID’s 1-4. The Master rack is always Rack ID 1. The
Rack ID of a stacked expansion rack is always equal to the first position of
SW3 that was turned ON to assign TDM’s on the rack’s CEX-2001 circuit
board . Using the previous two rack TDM Assignment example, the master
Rack ID is 1 and the second Rack ID is 3.
CEX-2001 Configuration Rules
• Dipswitch SW3 serves a dual function, TDM assign plus Rack ID.
• Rack ID in the XP GUI is equal to the 1st SW3 position thrown on a CEX
card.
• The Master rack CEX card always has SW3-1 ON, all others have SW3-1
OFF.
• Each rack must drive at least 8 TDM’s, but not more than 24 TDM’s.
Internal Programming Options
All internal programming choices are made via PCB mounted dipswitches.

used without crystal in socket - just short the pins closest to the desired
crystal to enable it. Or insert the desired crystal into the socket and
enable it by shorting the enable line to the crystal.
If Y1 and Y2 are populated with surface mount clock oscillators,
and Y3 is not installed (default), then 3 pin jumper posts J1 must be
used to select the correct frequency. A jumper shunt between the center
pin and pin closest to Y1 selects Y1 (48 kHz) and likewise a shunt to
pin closest to Y2 selects Y2 (44.1 kHz).
The clock oscillator on the Stacking card must match the system’s
master clock frequency. If the system audio sample rate is 48 kHz, then
the clock reference must be 24.576 MHz and likewise for 44.1 kHz, a
22.5792 MHz clock is necessary. If only Y3, a DIP socketed clock is
populated and not Y1 or Y2, then the appropriate matching clock
frequency must be installed in Y3.

Logic Input/Output Card
(LIO-2001)
Overview
The LIO-2001 is a programmable hardware GPI with a feature set
designed for broadcast studio control applications. Twelve independent,
opto-isolated solid state relay inputs and outputs may be programmed
through the XPoint GUI software to function as routable logic or trigger
ports.
Routable logic allows the user to make logic signal crosspoints in the
same way audio crosspoints are made. For instance, a closure on logic input
port 1 can be cross connected to logic output port 1. Later, the same closure
on input port 1 can be routed to logic output port 2, 3 or 4 etc. as required.
The output ports may be programmed to follow the input port state or to
invert it. Defining this behavior is useful when configuring the hardware for
normally closed applications. Input and output ports may be configured as
logic I/O only or may be “attached” to an audio signal. Routable logic
signals may be included as part of a Salvo.
Trigger ports allow the user to program a logic input to fire a predefined
Salvo or to make a temporary audio connection. Salvos make or break
multiple audio and/or logic crosspoints, while temporary audio connections are useful for IFB or EAS applications. When an input port is defined
as a trigger port, the corresponding output port is automatically allocated
for tally back. Tally back outputs provide a momentary closure whenever
the corresponding input is activated. Note that trigger ports serve one,
predefined function and are not routable.
See Configuring Logic I/O section in the Software Setup guide.
Input Ports
Each of the twelve LH1522AB solid state relay
input ports are configured as a floating photodiode,
(i.e. + input is the opto’s anode, - input is the opto’s
cathode). A 475 ohm current limiting resistor in
series with each negative input supports an external
supply voltage range of +5Vdc to +15Vdc. For
external supply voltages between +15Vdc and
+24Vdc, install a current limiting resistor of 220
ohms in series with each + input connection. Maximum forward photodiode current is 50mA.
When interfacing to a logic input port, we recommend the positive side
be connected to a fixed, positive dc voltage and the negative side switched
to ground to activate the logic input.

Quad Audio Network Card
(QA T-2001)
Overview
The Quad Audio Network card provides a robust and deterministic link
between multiple audio racks or control surfaces via fiber optic or CAT-5
cable. The 4 ports, A,B,C & D, may be independently configured in hardware
for either audio or control surface connections. Ports configured for Audio
Transport are called “AT” links, while ports configured for control surface use
are called “MT” or Mixer Transport links. Wheatstone’s XPoint software is
used to map the QAT ports to specific control surfaces and audio racks.
In a Multi-Tiered system, QAT cards are used as the “spoke” connections
between the Hub switch and up to 14 Remote Tiers. Control surfaces and
Satellite cages may then be connected to the master racks of the remote Tiers
through additional QAT cards.

Audio transport links must be installed in pairs (i.e. a QAT Network port
in the master chassis communicates to a companion QAT port or OAN card
in the remote chassis). Each QAT port transceives up to 64 mono channels (32
stereo signals). Each AT port must be configured as Local or Remote, and
Primary or Secondary. All Local/Primary ports transmit the sample rate clock
while all Remote/Primary ports receive the sample rate clock and drive it onto
its local backplane.

In systems incorporating control surfaces and DSP, each control surface
link is made to a QAT port co-located with its corresponding DSP cards.
These “MT” ports carry all fader, switch, logic, LCD meter, source and
destination information to and from the control surface and the companion
DSP cards located in the Remote Tier racks. Local/Remote and Primary/
Secondary settings do NOT apply to ports configured as Mixer Transport
links.

While the QAT provides a tremendous amount of flexibility and routing
power, please note the following design aspects:
• There is no audio data on an MT link.
• Control surfaces may not be daisy chained together off a single MT port.
• Audio cards in a remote chassis do not communicate directly with each other.
• In a single Tier configuration, a remote chassis cannot be daisy chained to
another remote chassis.

Digital Signal Processor Card
(DSP-2001)
Overview
The DSP-2001 card is the digital signal processing card used by the
Bridge System to mix and condition input signals. DSP cards in a given
system are physically identical. Their fuctionality is determined by input
and mix software which is loaded into each DSP card’s memory on surface
powerup. Wheatstone’s XPoint software is used to map each DSP card to
specific control surfaces and audio racks.
DSP cards are installed in pairs for radio style control surfaces, with one
DSP card acting as an input signal conditioner and the other as a mix
engine. Larger production and television surfaces with 5.1 surround
capabilities have a dedicated Master Mix engine along with multiple Mix
and Input DSP cards. The exact number of DSP cards requisite in large
systems is a function of the number of input channels and mix bus
requirements.
Each input fader has a dedicated DSP channel which is responsible for
gain, mode, phase, EQ, dynamics and metering. Likewise, each output mix
has a dedicated DSP channel responsible for summing, gain, mode,
metering and EQ/Dynamics on 5.1 Master mix outputs. DSP cards receive
instructions from control surfaces in real time over a Mixer Transport or
“MT” link. The mix engine DSP’s combine all of the console audio signals
as directed by a console’s faders, knobs and switches to produce the
various Program, Aux Send, Mix Minus and Monitor output mixes.
Racks may be fitted with one or more backup or “self healing” DSP
cards. If a hardware problem disables a primary DSP card, the affected
surface will load the appropriate code into one of the backup DSP cards and
continue to function. Replacing the faulty primary DSP card will return the
surface to normal operation, freeing the backup card for future use.
Warning messages present on the surface and in the XPoint GUI indicate
that a card has failed and requires attention.
Internal Programming Options
All internal programming are made via PCB mounted switches.

Microphone Card (MIC-2001)
Overview
The Microphone input/output cards accept 8 mono microphone input
audio sources and provides 8 mono direct output channels. A Signal Defini-
tions form in the supplied XPoint software allows the user to set attributes for
the input and output channels hardware including signal name, type, circuit
#, etc.
The balanced, mic level input signals are amplified by a remote controlled
dual stage preamplifier. Each preamplified microphone signal is fed to a
balanced, line level direct output. The preamplified microphone signal is also
converted to the digital domain by 24bit A-D converters operating at the
system’s master sample rate. Embedded logic routes each channel of audio
data into an available time slot of the card’s TDM bus. One TDM bus is
allocated for each card.
Analog Input Interface
The MIC-2001 uses an electronically balanced, monolithic preamplifier
capable of a wide range of input signals. While all microphone inputs employ
high frequency filtering components, be sure to install a high quality
microphone cable to help eliminate unwanted EMI and RFI artifacts.
Preamp specifications:
Nominal Mic Level = - 50dBm (2mV RMS), 150 ohms
Max input level = -10dBu
Headroom = 20dB
Gain Max = 84dB
Gain Range = +20 to +80dB
Phantom Power = 32V
Direct Output Level = 10dB steps
Internal Programming Options
There are no internal programming options on the MIC-2001 card.
