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

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 playe r 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 gat e 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

Operational Requirements Power

The XAP 400 automatically accommodates voltage requirementsof 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 2 5.

Installation ~ Networking Units

Networking Units 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 t he 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.

Installation ~ Networking Units

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.

Installation ~ LCD Programming

Flow Control (hardware)

The XAP 400 uses the RTS and CTS pins onthe RS-232 port to regulate the transmission and reception of data. You canenable 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 page23). If you select On (default) from the front panel menu, select Hardware as the flow control type in the Site Propertieswindow. If you disableflow 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 initializationstring 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 Yesto 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 Metermenu, then scroll through the options and press Enter when you reach the desired option.
