for each connector. Over-current protection is provided on the +15V pins to
prevent damage in the event of shorting. External power can be provided to
control devices when more current is required. See page 102 for maximum
cable run distances when using ClearOne Control Panels.
The latency or propagation
delay is <1ms.
Networking
Expansion bus
The digital mix-minus expansion bus (RJ-45 LAN) is used to connect up to eight
XAP 800/400s and 16 XAP TH2 units, where the total number of microphone
inputs does not exceed 64. The maximum distance between interconnected XAP
800/400 or PSR1212 units is 80 feet (24 meters). Connecting a XAP TH2 must not
increase the cable length between two PSR1212s, XAP 800s and/or XAP 400s
beyond 80 feet. ClearOne recommends that category five twisted-pair (10BaseT
LAN) cable be used.
The expansion bus (E-bus) allows audio routing between destinations on the
E-bus network. The E-bus contains 12 independent digital audio buses labeled O—Z
which can route mic or line level inputs in any combination across the E-bus
network. The O—Z buses are divided into two groups (O—R and S—Z) based on their
capabilities and default settings. The E-bus also contains four PA adapt/acoustic
echo cancellation reference buses, four global gating buses, and one control bus.
• O—R buses. These four audio buses are defaulted as the mic mix buses; they
can communicate the NOM count and mic mixing parameters across the

Introduction ~ Operational Requirements
network to other XAP 400s. All gated mics are routed to the 0-bus by default.
• S—Z buses. These eight buses are defaulted as auxiliary mix buses. They
are used to route auxiliary audio, such as from a CD player or VCR, to and
from other units on the network. These buses are also used as mic mix buses
when NOM count is not required.
• PA Adapt/Acoustic Echo Cancellation Reference buses. These buses
allow an input from a XAP 400 to reference an output on another linked
XAP 400/800. See PA Adapt and AEC Reference on page 33 for more
information.
• Global Gating Groups A-D buses. These mix-minus buses are defined as
microphone gating groups which support first-mic priority, maximum
number of mics, etc. and work across all linked XAP 400/800s. Unlike the
audio buses, they contain only mic status and gate parameters. See page 41
for more information about gating groups.
• Control bus. The control bus is an independent channel from the E-bus’s
audio channel; it uses a different pair of wires on the same E-bus cable. This
allows control information to pass even if the units are not using the audio

Expansion bus connections
Using the Expansion Bus ports (RJ-45), you can connect up to eight XAP 800/400s
and 16 XAP TH2 units, where the total number of microphone inputs does not
exceed 64. Make connections between units in daisy-chain fashion using the short
RJ-45 jumper. If your units are further apart, use category five twisted-pair cable.
The maximum distance between interconnected XAP 800/400 or PSR1212
units is 80 feet (24 meters). Expansion bus cable length is calculated between
XAP 800s/400s and PSR1212s. The cable connecting a XAP TH2 to the network
is included in the cable length between the XAP 800 or XAP 400. For example, if
the cable from the XAP 400 to the XAP TH2 is 50 feet and the cable from the
XAP TH2 to the XAP 800 is 50 feet, then the total length between the XAP 400
and XAP 800 is 100 feet which is beyond the maximum 80-foot limit.
11
To create an expansion bus network
1. Plug the expansion bus terminator in the Expansion Bus In connector of
the first unit in the network.
2. Connect the RJ-45 jumper cable (or Cat 5 twisted pair cable) to the
Expansion Bus Out connector of the first unit in the network and
Expansion Bus In connector of the second unit. Continue connecting units
in the same fashion.
3. Plug the expansion bus terminator in the Expansion Bus Out connector on
the final unit to complete the network connections.
If the E-bus network is not connected properly, the front panel LEDs will
flash on the units that are physically connected to the network. To correct
the problem, check for broken connections and reconnect the expansion bus
cables.
Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760
Figure 2.4. E-bus connection diagram
ClearOne recommends that
the first unit in your E-bus
network be a XAP 400 or
XAP 800 rather than a XAP TH2.
RS-232 system-wide control can be provided by any
unit in the network.

If the same device ID is
assigned to more than one
unit on the E-Bus network,
the Meter LED “+12” will flash
red, the Mic LED “2” will flash
green, and the Off LED will flash
red on the affected units. To correct
the problem, change the device ID
on one of the conflicting units.
You can also use G-Ware
to select a mixer mode.
See page 25.
Device IDs
Once your expansion bus connections are made (and if you have more than one
XAP 400 at a site), you need to set up a unique expansion bus device ID number–a
network address–for each XAP 400 on the network. As shipped from the factory,
all XAP 400s default as device ID 0.

Mixer mode
There are two mixer mode settings: slave (default) and master. A master unit is not
required in a networked system and in most installations, all units will be slaves.
Master units ignore audio from upstream units. This prevents audio from being
received from units above the master unit in the network. However, global control of
the system is still maintained by whichever XAP 400/800 or PSR1212 unit is
connected to a control device through its RS-232 or RS-485 ports. Control is not
affected by master/slave designations.
Figure 2.5. E-bus network with master units
In Figure 2.5, the third unit in the network is a master. It prevents the audio
from the first and second units from being passed down the network chain.
Likewise the second master unit in the network will not pass on the audio from the
unit before it. The third unit provides system-wide control through a connection to
its RS-232 port.
To select a mixer mode
1. Press the front panel Enter button and scroll through the menu until System
menu is visible. Press Enter to select the menu.
2. Scroll through the System menu and select Mixer Mode.

ClearOne recommends that
you leave Flow Control
enabled.
The modem initialization
string can only be set via
the MINIT serial
command (see page 130) or the
G-Ware software. It cannot be set
through the front panel LCD.
Flow Control (hardware)
The XAP 400 uses the RTS and CTS pins on the RS-232 port to regulate the
transmission and reception of data. You can enable or disable flow control on the
front panel of unit and select the flow control type in the Site Properties window of
G-Ware (see page 23). If you select On (default) from the front panel menu, select
Hardware as the flow control type in the Site Properties window. If you disable flow
control on the front panel, select None in the Site Properties window. When None is
selected, the XAP 400 ignores flow control, making the connected external control
device ensure that data is not lost. Software flow control (Xon/Xoff) is supported by
the XAP/PSR units and is only used with a pass-through device, such as a modem.
To avoid communication errors, ClearOne strongly recommends that you
connect all DB9 pins and enable flow control when connecting to a PC.
Enable Modem
This parameter configures the RS-232 port for connection of a modem. When On is
selected, the XAP 400 will send an initialization string to the modem on power-up
and require a password before data transfer is allowed through the port. When Off
(default) is selected, the password is disabled.
To use the XAP 400 with a modem
You can set the modem
password using the
MPASS serial command
(see page 131) or in G-Ware (see
page 26).
1. Match the baud rate of the modem to that of the XAP 400.
2. Turn off Serial Echo on the modem.
3. Turn off the modem’s response mode (e.g., no OK messages, ring, etc.).
4. Enable auto-answer on the modem.
Clear Password
This parameter allows you to erase the serial port (modem) password in case it has
been forgotten. Select Yes to keep the current password or No to erase it. Press
Enter to enable your selection.
Meter menu
There are 10 submenus under the Meter menu: Inputs, Outputs, Processing, ERL,
ERLE, Telco RX, Telco TX, TERL, TERLE, and Default Meter. The meter selection
determines what is shown on the front panel peak-level LED display. When the meter

Audio is routed in the Matrix Screen (see Figure 3.20 on previous page). To access
the Matrix Screen, click on the Matrix button on the Flow Screen. To return to the
Flow Screen, click the Flow Screen button.
The XAP 400 routing matrix has 25 possible input sources and 26 output
destinations, with level control at each cross point. Any input or combination of
inputs can be routed to any output or any combination of outputs. To clear the
matrix, click the Clear Matrix button located above the Routing Key.
To route an input, click in the routing matrix at the intersection between the
input and the output. A mic input can be designated as gated (yellow) or non-gated
(blue) by clicking repeatedly in the cross point. All other input cross points will be
colored green.
Expansion bus O—Z routing
Audio on any XAP unit in the E-bus network can be placed on the bus or taken off
the bus and routed to any destination within the unit. The XAP 400 has 12 digital
mix-minus buses:
Figure 3.23. Cross Point

• O—R buses are defaulted as the mic mix buses and can communicate the
NOM count. Gated mics are default routed to the O-bus.
• S—Z buses are defaulted as the auxiliary mix buses. They are used to carry
auxiliary audio such as that from codecs and XAP TH2s. These buses are
used as mic mix buses when NOM count is not required.
Process A—D routing
There are four processing blocks on the XAP 400 (Processing A—D). With these
processing channels, you can apply filters, EQ, or other processing settings to an
input or a group of inputs which can then be routed to a single output or group of
outputs. See page 49 for more information on processing settings.

Use this window to select which signals will be used by the four Virtual
Reference points. The routing matrix portion of this window can not be edited.
Virtual references are used when you need to reference multiple outputs. For
example, if you have stereo outputs (L, R) near a block of mics, you would want
the mics’ echo canceller to reference both the left and right outputs. By using a
virtual reference, the echo canceller will be able to reference both signals. This
means you don’t need to use a dedicated output to combine signals.
Or, you may have mics routed to the PA output but you don’t want the echo
canceller to reference this audio. By using a virtual reference, the echo canceller
can sample all signals routed to the PA output, minus the mic signals.
To create a virtual reference
1. Select the input signals you want included in each virtual reference by
clicking the cross points.
2. Because AEC requires a physical output reference to track output gain
changes, you need to select an output reference for AEC to function properly
with a virtual reference. Use the lists at the bottom of the window to select
which output you want AEC to use to track gain changes.

Gate
The XAP 400 has unique gating parameters which control microphone activation.
The Gate button on the selected input in Inputs 1—4 window opens the Gate
configuration window where you can establish the gating parameters for the input.
Activation
There are three mic activation settings: Auto Gate, Manual On, and Manual Off.
• Auto Gate determines mic gating based on the input level and gating settings
for the gating group the input is assigned to. It contributes to and is affected
by all gating group settings such as NOM, chairman override, etc.
Figure 3.35. Gate window
• Manual On activates a mic, provided it does not exceed max NOM
requirements of the gating group that the input is assigned to. It is included in
the NOM count.
• Manual Off deactivates a mic.
Chairman Override
Chairman Override provides gating priority for this mic input over any other mic
input within the same gating control (mixer) groups. When a mic with Chairman
Override enabled gates on, all mics which don’t have Chairman Override enabled will
gate off. Default is off.
Adaptive Ambient
Adaptive Ambient adjusts the ambient reference level as noise and room conditions
change. When adaptive ambient is on, the mic channel monitors the ambient noise
level on the input and adjusts the ambient level reference automatically. This means
that the gate threshold level automatically increases or decreases based on back-
ground noise. If Adaptive Ambient is turned off, the input will use the fixed ambient
level specified in the Ambient Level box as its gating reference. Default is on.
PA Adaptive Mode
PA Adaptive Mode uses loudspeaker audio level on a specified output as the new
ambient level when audio is present at the power amplifier. This prevents
loudspeaker audio from gating on the mic, while still allowing people in the room to
gate on microphones as they speak–provided that their voices are louder than the
loudspeaker audio. For example, you might decide to play background music from a
CD player during a presentation. PA Adapt Mode allows you to use the output routed
from the CD player as the ambient reference to prevent the CD player’s audio from
gating on microphones. An output must be specified as the PA Adaptive Reference
(this is the same as the AEC reference) for each mic in the system. Default is on.

Gate Ratio
39
Gate Ratio specifies how much louder the audio level must be above the ambient
level before the channel gates on. The gate ratio range is from 0 to 50dB. Default is
15dB.
Hold Time
Hold Time determines how long the channel stays gated on after the audio is below
the threshold. The hold time range is from .1 to 8.0 seconds. Default is .3 seconds.
Off Attenuation
Off Attenuation sets the amount of level reduction applied to a channel when it is
gated off. The range is from 0 to 50dB. Default is 12dB.
Ambient Level
Ambient Level is available only if the Adaptive Ambient feature isn’t enabled. Use
Ambient Level if you want to specify a fixed reference point rather than one that
adjusts for background noise. The range is from -80 to 0dB. Default is Off.
Decay Rate
Decay Rate determines how fast a channel gates off after the hold time expires.
Default is Medium.

Gating Group Select
In addition to specifying gating characteristics for each mic input, you can assign the
inputs to a gating group for greater flexibility and control. When inputs are
assigned to a gating group, the gating information from the inputs is used to
control how the entire mixer behaves.
The XAP 400 features four internal gating groups (Internal 1—4) and four
global gating groups across the expansion bus (Global A—D). Microphones can only
be used in one gating group at a time. If an input is not assigned to a gating
group, that mic’s gate properties are independent and have no effect on any other
gating group. When gating groups span two or more units (global gating groups),
the settings must be the same for each unit attached to the global gating group.
Mic inputs are routed to Global Group A by default.

one time within a gating group. For internal groups, the maximum number
of mics can be from 1 to 4. For global groups the maximum number of mics
will vary depending on how many mic inputs are assigned to the gating
group (up to 64). You can also select All for the global groups–which
means all mics could gate on.

3. Leave 1st Mic Priority selected (default) to enable this feature; otherwise,
clear the selection to disable it. ClearOne recommends leaving this setting on.
This setting helps maintain maximum audio intelligibility by allowing only
one mic to gate on to a participant’s voice. 1st Mic Priority allows more
than one microphone to be activated at same time–it simply restricts mics
from gating on to the same audio source. It does this by determining the
audio level received by all mics when the first mic is gated on. This audio
level is then used as the ambient level for the gating group. If this feature is
disabled, usually two or more microphones gate on when only one person
speaks.
4. Select last-mic operation from the Last Mic Mode list. There are two
options for Internal groups: Last On and Off. If you are configuring Global
groups, you can select from the mic inputs assigned to the Global group in
addition to Last On and Off.
Last On leaves the mic that was activated last full on until another mic input
is gated on. The Input setting allows you to select which mic input the XAP
400 leave on when all mics gate off. If Off is selected, all mics will gate off
when no audio is present. It is preferable in most applications to leave a mic
on so the remote participants don’t think they have lost their audio
connection. Off is typically only used when you are conferencing multiple
sites and need to reduce background noise.

Optimizing input gain structure
How you adjust an input’s gain directly affects sound quality. The optimal input gain
setting is one which is adjusted as high as possible above the noise floor without
introducing clipping. Clipping can cause distortion which can damage amplifiers and
loudspeakers.
To adjust the input level properly, place a signal on the input at the maximum
level it will generate. Adjust the input gain until the peak level of the input, as
shown on the Input meter, just begins to enter the red (clipping) zone, then reduce
the gain slightly until peaks no longer climb into the red zone. This setting will
ensure that the XAP 400 maximizes the signal-to-noise ratio without clipping the
signal.

When you assign a compressor to a compressor group–such as a group of three,
configured for bass, midrange, and treble–the compressors will monitor each
other. When one compressor channel compresses, all compressors in the group
compress together. When configured properly, this results in a smooth audio
response throughout the frequency range, with no bass, midrange, or treble
dropouts. A given compressor group must be configured for a single XAP 400

enclosures located various distances from the listening area.
Other types of delay to consider when establishing delay parameters are
delays which occur naturally as a result of processing operations within the

CHAPTER 4 : A d v a n c e d
Configuration
Presets
Overview
For many audio conferencing applications, a great deal of system flexibility is needed
to meet the challenges presented by changing meeting or conference room
requirements. These requirements may include changes in muting, audio sources,
room orientation, or room combining. And ideally, these changes are made
instantaneously–without interrupting or affecting any meetings in progress.
Using presets enables you to accommodate these changing room requirements
quickly and efficiently. When you create a preset, you are essentially creating a
single room configuration option. Presets can be programmed with a variety of
routing, level, gating, delay, filter, and EC reference settings to meet specific
application requirements. You can change every unit parameter or a select few
depending on your room needs. XAP 400 presets are unique in the sense that they
operate independently of other presets in the unit. When a preset is run, only the
selected inputs/outputs are changed–all other settings in other presets remain
unchanged and are not reset. This means you can change audio routing and
configuration settings in a room without affecting settings in other rooms (such as
gain). You can create up to 32 presets for the XAP 400.
Presets can be executed in a variety of different ways including the Execute
Preset utility in G-Ware, the front panel controls of the XAP 400, RS-232
external control devices, RS-485 control devices (ClearOne Control Panel and
XAP IR Remote), logic in/out, and contact closure. You can also create macros
which can run multiple presets. These options give you tremendous flexibility when
designing your installations and will be described in more detail in this chapter.
Presets are used only
within the local
XAP 400 unit. However, if
a preset is part of a macro, it can be
activated on a networked XAP 400
unit.
Creating Presets
Presets are created in G-Ware using the Preset mode. To switch to Preset Mode,
click the Preset Mode button on the toolbar or the Preset Mode button on the Flow
Screen. The Preset Mode window (see Figure 4.2) consists of the Preset
Configuration Pane (left side of the window), the G-Ware menus and toolbar
(although most options are not available because they do not apply to presets), and
the Preset Matrix Screen. There is no Flow Screen in Preset Mode since all
configurable settings can be accessed from the Matrix Screen.

A typical use for Preset Mask Control Status B is a room combining
application which uses automatic partitions with sensors or triggers which set the
pin to high (H) when the partition is closed and to low (L) when the partition is
open. For example, if pin 1 is connected to the first partition and Pin 3 is
connected to the second partition, then the Preset Mask Control Status B settings
shown in Figure 4.4 will activate the preset when the first partition is open and the
second partition is closed.

Storage space
In a realistic preset configuration scenario, it is highly unlikely that you would reach
the storage capacity of the unit. In the event that you exceed the preset storage
space, G-Ware will alert you when you try to save the preset. You will be asked to
reduce the number of cross point changes or the number of macros in the preset. As
a general rule, if you make cross point changes to three-fourths of the matrix, you
can establish a maximum of 128 nested macros for a given preset.

Running presets
Presets can be run from G-Ware or the front panel controls on the XAP 400. You
can also program external control devices (such as AMX or Crestron, ClearOne
Control Panels, XAP IR Remote, and GPIO devices) or use macros to run presets.

Running multiple presets simultaneously
To run multiple presets at the same time, you need to create macros (see page 67). A
macro is a series of commands which can be executed from G-Ware or by using any
external control device. Typically you will create a macro for each configuration or
group of presets you want to run at the same time. This ability to run multiple
presets is critical in applications such as room combining. However, not only do you
need to be able to run multiple presets simultaneously, you also need to be able to
change presets without affecting other presets.
It is also possible to assign
states to presets when
creating Remote Panel,
serial, or GPIO control. However,
unless you create macros, you will
only be able to run one preset at a
time.
In order for this to happen, the system needs to know which presets have been
run and shouldn’t be rerun and which ones are ready to run. You supply the system
with this information by setting the state (or flag) of the preset when creating the
command line in the macro. The three options are:
0 = to set the state to off
1 = to execute the preset and set the state to on
2 = to execute the preset and set the state to off

Page 71
Advanced Configuration ~ Presets
Figure 4.9. Assigning a state to a preset command in the Macro Editor
If a preset is flagged as “On,” nothing will happen when the preset is
executed again because the system knows it has already been run. This prevents
any manual adjustments that are made during the course of the meeting (gain,
muting, etc.) from being lost.
Room combining example
65
In the room combining scenario depicted in Figure 4.10, there are four possible
room configurations using six presets (P1—P6). In order to change configurations
without disturbing meetings in progress, a macro must be created for each
configuration that tells the system what to do with each of the six presets.
You can also create a
macro to set all preset
flags to 0 which ensures
all presets are ready to run again.

Advanced Configuration ~ Presets
The four macros (one for each configuration) are set up as follows:
When the room is in Configuration 1, running the Configuration 2 macro will
change the presets to the following states:
• P1 does not change because the flag is already set (1)
• P2 and P3 clear their states (0) so they can be run
• P4 runs and sets its state to on (1) which prevents other presets from
reruning it
• P5 and P6 clear their states (0) so they can be run
When the room is in Configuration 3, running the Configuration 1 macro will change
the presets to the following states:
• P1 and P2 run and set their state to on (1) which prevents other presets
from reruning them
• P3 does not change because the flag is already set (1)
• P4, P5, and P6 clear their states (0) so they can be run

Macros
A macro is a series of commands which can be run from G-Ware, the front panel
controls, or by using any external control device. Macros streamline the operation of
the XAP 400, allowing you to make quick configuration changes and, as previously
discussed, making it possible to execute multiple presets simultaneously (see pages
64—66). Macros can also contain commands that are executed on other XAP units.
See pages 107-108 for a list of commands which can be used in macros.
The XAP 400 is designed to support up to 255 macros, with an average of
150 command lines each. In the unlikely event that you exceed G-Ware’s capacity,
you will be notified with a warning that indicates the command line at which
memory is exceeded.
Creating macros
There are two ways to create macros in G-Ware: the Macro Recorder, which
records your onscreen selections, and the Macro Editor, which allows you to
directly create command lines. The Macro Editor is also used to edit macros
created using the Macro Recorder.
67
To create a macro using Macro Recorder
1. Click the Macro Recorder button on the G-Ware toolbar. The Macro Record
window opens and the mode is changed to Macro on the status bar.
Figure 4.13. Macro Record stop window

2. Select the macro number from the Macro to Record list, then click Start.
3. Make any routing and input/output configuration changes (such as gain
adjustments, mute, etc.) to be included in the macro. Make these changes
the same way you made changes in Configuration mode (see Chapter 3:
System Configuration for more information).
4. Click Stop in the Macro Record window in the upper right-hand corner of
the screen. This stops the macro recording and opens the Macro Editor
window. See page 69 for editing instructions.

CHAPTER 5 : O p e r a t i o n
This chapter explains how to use your XAP 400 and G-Ware to make, answer,
disconnect, and mute calls. It also describes how to use the different utility programs
and monitoring views in G-Ware.
Using the XAP 400
To answer a call
Depending on how you have configured your XAP 400, an incoming call can ring on
the telephone set connected to the XAP 400, the speaker output and the receive
output, as well as pass a serial ring to a control device. An incoming call will also
cause the front panel On LED [D] to flash. You can answer the call using any of the
following methods:
• Press the On button [A] on either the front panel or your remote control.
This will route the call through the XAP 400. The green On LED [D] will
light. The red Off LED [C] will extinguish. Upon connection, the XAP 400
automatically adjusts to the line conditions.
• Answer the call by picking up the telephone handset and talking to your
party over the telephone.
• Answer the call using external control such as an AMX or Crestron touch
panel, GPIO device, or RS-485 device. See page 104 for serial commands.
To make and disconnect a call

1. Call the party using your handset.
2. After the other party has answered, route the call through the XAP 400 by
pressing the On button [A]. The On LED [D] will light and the XAP 400
will take control of the call, disabling the telephone set. You may now safely
hang up the handset without disconnecting your call.

If using an external controller, it is not necessary to press the On button [A].
The DIAL serial port command automatically engages the XAP 400. See
Serial Commands, page 116.
3. When the conversation is complete, press the Off button [B] to disconnect
the call. You can also disconnect using an external controller. If the handset
is off hook, audio will be routed to the telephone.
If your call is through the handset only (the red Off LED [C] will be lit),
hang up when the conversation is complete.
Using the Dial Interface
To make and disconnect a call
1. Open the Dial Interface by clicking the Dial button on the Flow Screen.
2. Activate the telephone interface by clicking Connect.
3. When the green light above the Connect button illuminates, enter the
number to be dialed, including any dial-out prefixes.
The number is dialed as you enter the numbers. You do not need to click
Dial.
4. When you are finished with the call, click Disconnect to end the call.
If there is noise on the phone line during a call, you might need to click the Re-Null
button to force the interface to readapt to the line. After the unit sends a noise burst
down the line for adaptation, it automatically switches to auto adapt mode. The
receive signal is muted during a noise burst.
To dial multiple numbers
Numbers can be dialed one at a time or a string can be dialed at one time
(In-Block). When dialing multiple numbers, the maximum length of the string is 40
characters. A comma is interpreted as a two second pause. If a command to dial is
issued while the unit is on hook, the unit will go off hook and dial the number.

Touch-tone dialing
Through the expansion bus (and serial commands), the XAP 400’s touch-tone
(DTMF) dialing capability can be accessed. This allows outbound calls to be initiated
by the XAP 400 without requiring an external dialer or telephone set. This feature
continues to function after connection, enabling the user to issue tones for voice
mail/pager interaction. See Serial Commands on page 116.

The G-Ware Switcher utility, introduced with G-Ware version 4.5, allows you to
alternate between different G-Ware software versions that are installed on the
same PC.
For example, if you need to upgrade the firmware on your ClearOne unit(s),
G-Ware Switcher allows you to easily switch to an earlier version of G-Ware (such
as 3.5), save the site files, and then switch to a later version (such as 4.5) to
upgrade the firmware.
Prior to the 4.5 release, the older version of G-Ware had to be removed before the
new version could be installed. If you need to use multiple versions of G-Ware,
you must install them in different directories (folders) on your PC, or G-Ware
Switcher will not work.
Before Using G-Ware Switcher
1. Load G-Ware 3.5 in a unique directory (path), as shown in Figure 5.16. Do
not select “Add Icon to Desktop” when you are asked if you want to do so
during the installation process.

CHAPTER 6 : C o n t r o l
There are many ways to control your XAP 400 and networked units. This chapter
explains how to set up control for the Control/Status A port using GPIO Builder, the
XAP IR Remote and ClearOne Control Panels using Remote Builder, and RS-232 port.
GPIO Builder
Control/Status A
GPIO stands for general-purpose input/output. The GPIO Builder is used to establish
the pin assignments for the 16 user definable pins on Control/Status Port A. These
pins provide control via contact closure and status via open collector functions in the
unit. Note that the pins numbered in blue are command pins; the pins numbered in
green are status pins. The default pin assignments are listed on page 98. You can
open GPIO Builder from the Flow Screen or the G-Ware toolbar.
To program control/status pins
1. Select the Control/Status A pin you want to configure.
The current (default) pin assignment is displayed in the Active
(Low)/Inactive (High) Command box.

RS-232 Port
Remote Modem Access
The modem password is
created in the Unit
Properties window (see
page 26) or by using the MPASS
serial command (see page 131).
You can access the unit remotely through a modem connected to the serial port. To
enable this feature, configure the port for modem mode.
When in modem mode, the serial port will send an initialization string to the
modem upon entering the mode or upon power-up of the unit. You program the
initialization string in Site Properties window in G-Ware. Typical configurations
you set with the initialization string include setting a fixed baud rate for the unit
and setting up auto-answer parameters.
You must enter a password before you can control the system this way. The
default password is blank (a carriage return). You can change it to any
combination of letters and/or numbers up to 12 characters. It is not case-sensitive.
When you establish a valid serial connection with the unit in modem mode,
the unit will wait for a carriage return. When you have entered a carriage return,
the system will prompt you to enter the password. If there is no activity for five
minutes on the serial port while in modem mode, the unit will re-prompt for the
password.
Serial commands
Serial commands can be passed through the XAP 400 RS-232 port using Hyper
Terminal, touch panels, or other compatible remote control devices. To learn more
about serial commands, see Appendix E.

Command strings
By creating command strings, you can use your XAP 400 to control equipment such
as lighting, projectors, and room dividers as well as other ClearOne products. A
command string is passed to the connected device via the XAP 400’s RS-232 port.
You can create up to eight customized serial command strings (limit 80 characters
each) in the Command Strings window. To open the Command Strings window, click
the Command Strings toolbar button.
