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 L AN) 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
network to other XAP 400s. All gated mics are routed to the 0-bus by default.
Networking
The latency or propagation
delay is <1ms.

Power
The XAP 400 automatically accommodates voltage requirements of 100–240VAC,
50/60Hz, 15W.
Telephone line
The XAP 400 model operates on a standard analog telephone line and connects to
the telephone system with a standard RJ-11C modular jack. If you do not have an
RJ-11C jack where you want to install your XAP 400, call your telephone company
for installation.
The XAP 400 can be configured to meet compliance requirements of different
countries via the G-Ware software. See page 25.
Operational Requirements
Warning: The country code
must be set correctly in
G-Ware to ensure that the
unit operates properly when
connected to the telco network and
that it complies with the country’s
telco requirements. Changing this
code to a country other than the
intended country of operation might
cause the XAP 400 to be noncompliant.
!
• S–Z buses. These eight buses are defaulted as auxiliar y 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
link. The XAP 400 supports the full set of commands through the control bus.

Equipment placement
The XAP 400 models are designed for installation in a standard 19-inch equipment
rack. You can also purchase side panels for desktop placement. See Appendix D for a
list of accessories.
Environmental
The XAP 400 can be safely operated in a room with varying temperatures between
32 °F/0 °C and 110 °F/43 °C.
Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760
The XAP 400 is designed for easy installation and setup. All connections are made
through rear-panel connectors. This chapter provides instructions on installing the
units and making initial connections, creating an expansion bus (E-bus) network,
assigning device ID numbers, selecting the mixer mode, and using the LCD menu.
The diagram below illustrates the typical connections that are made for a single-unit
XAP 400 system. The default routing settings in the G-Ware Matrix Screen allow
the XAP 400 to work out of the box for this type of installation.

To connect the unit
1. Place the unit in a standard 19-inch rack and attach it securely.
2. Connect your telephone line from the wall jack to the RJ-11C Line jack [I].
3. Plug your telephone set into the RJ-11C Set jack [J].
4. If you are using a custom controller for control and status, plug it into the
DB25 Control/Status A or B port [G].
If you are using an external RS-232 controller, connect it to the
RS-232 port [F].
5. Wire the inputs and outputs to the XAP 400 using the provided threeterminal Phoenix push-on connectors. These connectors are designed for
easy wiring; simply insert the desired wire into the appropriate connector
opening and tighten down the top screw.
• Inputs 1–4 [B] Mic or line level inputs
• Inputs 5–8 [D] Line level inputs only
• Outputs 1–8 [C] Line level outputs
6. If you are using a ClearOne Remote Panel, wire it to the RS-485 port [K]
using the provided four-terminal Phoenix push-on connectors.
7. Connect the speaker wire to the + (red) and – (black) binding post
connectors. A 4–16Ω speaker can be directly connected to the XAP 400,
eliminating the need for an external power amplifier.
8. Plug in the XAP 400 to complete the installation. The power output [A] will
operate at any level between 100–240VAC and 50–60Hz.
If you are installing only one XAP 400 and are not connecting it to any other XAP
or PSR1212 units, you have completed the hardware installation.

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760
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.
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.
Figure 2.4. E-bus connection diagram
Networking Units
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.

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.
To assign device IDs
1.
Press the front-panel
Enter
button, then scroll through the menu until the
System
menu is visible.
2. Press
Enter
, then scroll through the menu until
Device ID
is visible.
3. Press
Enter
, then scroll through the eight (0–7) options. When the desired
Device ID is visible, press
Enter
to select it. (You can also set the Device ID
in the Unit Properties window of G-Ware software see page 25.)
4. Repeat this process for each XAP 400 on the expansion bus network.
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.
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.
3. Select the mixer setting you want to use.
Repeat for additional units.
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.

16
Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760
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
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
is selected in the LCD menu tree, the LCD displays peak level indications as well.
Use the ▲ and ▼ buttons to select the Meter menu, then scroll through the options
and press Enter when you reach the desired option.

G-Ware Requirements
ClearOne’s G-Ware software provides an easy interface for configuring and
controlling your XAP 400. While some configuration can be done using the front
panel LCD menus, G-Ware is required to complete the custom configuration of your
audio conferencing system. If you are using the default settings, no configuration is
necessary.
This chapter describes how to install G-Ware, create a site, and set up the
telco portion of your system. It also describes all configurable parameters of your
system. These descriptions are designed to be used as a guide as you make
adjustments for your particular installation. It is not necessary to configure all
parameters.

Creating floppy disk copies
Depending upon the computer equipment you have available, you might need to
install G-Ware software from floppy disks rather than the included CD. To do this, a
Disk Copy program is provided in G-Ware that allows you to transfer G-Ware to
floppy disks. You will need a PC with a CD-ROM drive to make the transfer. After
installing G-Ware on the CD-ROM-equipped computer, you can access the Disk Copy
program in the following way:
• From the Windows Start menu, select Programs, ClearOne G-Ware, and
then Create Install Floppy Disks. Follow the onscreen prompts to complete
creation of the floppy disks.
To install G-Ware
1. Boot the PC to the Windows operating system. Ensure that all other
programs or applications are closed. Insert the Audio and Video Products
CD into the CD-ROM drive.
If the Autorun feature is enabled on the PC, the ClearOne Welcome window
opens. Click the Software tab and select G-Ware.
If the Autorun window does not open, open the Windows Start menu and

Creating a new site
New site files are created through the Site Properties window in G-Ware. A site file
contains all information about a particular installation including all unit settings and
properties. It also provides G-Ware with the necessary information to communicate
with the site hardware using your PC. Open G-Ware by double clicking the desktop
icon or by selecting G-Ware from the Start menu.
To create a new site
1. Open the Site Properties window by selecting New Site from the File menu
or by clicking the New Site button on the toolbar.
2. In the Site tab, enter the site name, author, company, location, room, and
description, using the Tab key or mouse to select each field.
3. Click the Comm tab. Select the COM port, baud rate, and flow control you
want to use. ClearOne recommends that you leave Flow Control set to
Hardware. The Software setting is not supported by XAP/PSR units and is
typically used with modems.
4. If you plan to use a modem, select Use Modem and enter the phone number,
initialization string, and reset string.
5. Click the Security tab. Enter the site password in the Site Password box.
Click File Access Password to create a password for the Site File.
