EXPANSION BUS

The Converge Pro Expansion Bus (E-bus) allows you to connect multiple Converge-Pro units together to create
powerful audio and conferencing solutions for any size venue. The E-bus is a proprietary digital audio bus that
provides control and audio data links between Converge Pro devices.

Expansion Bus Connections

Using the E-bus Link In and Link Out ports, you can connect up to 28 Converge Pro 840T/880/8is and 16 Converge
Pro TH20 units, where the total number of microphone inputs does not exceed 64.

Connect Converge Pro units in daisy-chain fashion (as shown below) using the 18” straight-through patch cable
included with each unit (Part # 830-150-004). For larger distances between units, use CAT 5 twisted pair cable with
RJ-45 connectors.

The maximum cable length between connected Converge Pro units is 200 feet (61 meters).

Audio and Control Buses

The E-bus allows audio routing between source devices and destination devices on the E-bus network. The E-bus
contains 12 independent digital audio buses labeled O–Z, which can route mic or line inputs in any combination
across the E-bus network. 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 generally used for routing microphone audio between Converge Pro
devices. Information about the number of gated microphones (NOM count) and other relevant information for the
microphone mixers are tracked for microphones routed to these buses. By default, all microphones are routed to
the O bus.

S–Z Buses: These eight buses are line input mixer 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 mixer buses when
NOM count is not required.

PA Adapt/Acoustic Echo Cancellation Reference Buses: These buses allow an input from a Converge Pro
device to reference an output on another linked Converge Pro device for AEC purposes. See AEC Reference and
AEC for more information.

Global Gating Groups A-D: These buses are microphone gating groups that support First-Mic Priority, maximum
number of mics, etc. and work across all linked Converge devices. Unlike the audio buses, they contain only mic
status and gate parameters. See Mic Gating and Gating Groups for more information.

Control Bus: The control bus is an independent channel from the E-bus’s audio channel. This allows control
information to pass even if the units are not using the audio link. Converge Pro devices support the use of the serial
command set through the control bus.

Chapter 2: Expansion Bus & LCD Programming 19

DEVICE IDS

Device IDs provide unique identifiers for all Converge Pro units that are linked together. After making E-bus
connections between Converge Pro units, you must set a unique Device ID number for all units of the same Device
Type in the network.

Device Types and IDs

Converge Pro Device Types and Device IDs by model are as follows:

Model Device Type Device ID Range

880 1 0-7

TH20 2 0-F

840T 3 0-7

8i A 0-7

NOTE: All Converge Pro units ship from the factory with a default DID of 0.

Assigning Device IDs

RS-232

There are two parameters in the RS-232 menu: Baud Rate and Flow Control. To change these settings, use the
following procedure:

Use the Menu Dial to highlight Baud Rate or Flow Control

1.

Press the Select button

2.

Select the desired value using the Menu Dial

3.

Press the Select button to set the selected value

4.

Press the Esc button to return to the Settings menu

5.

You can also use the Comm tab of the Unit Properties screen to change these settings.

Baud Rate

This parameter allows you to set the baud rate to 9.6kbps, 19.2kbps, 38.4kbps, 57.6kbps, or 115.2kbps. The default
is 57.6 kbps. Select the baud rate you want to use, then press the Select button. A message appears on the LCD
display indicating the change is in progress, and another indicating the change is complete. When finished, the
display returns to the RS-232 sub-menu.

Flow Control (Hardware)

Converge Pro devices use 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 Unit
Properties window in Console.

If you select On (default) from the front panel LCD menu, select Hardware as the flow control type in the Unit
Properties window. If you disable flow control on the front panel, select None in the Unit Properties window.
When None is selected, Converge Pro units ignore flow control, and the connected external control device ensures
that data is not lost.

NOTE: ClearOne recommends that you leave Flow Control enabled and connect all DB9 pins to

avoid communication errors.

Network

The Network submenu displays the unit name, IP address, Gateway, and Subnet Mask settings for the Converge
Pro unit. You cannot change any of these settings from the Network submenu. Use the Unit Properties screen in
the Console software to change these settings.

DID

The DID submenu allows you to select a Device ID for the Converge Pro unit. Select the DID you want to use, press
the Select button. Answer Yes to the prompt to change the DID, or No to keep the existing setting.

You can also use the General tab of the Unit Properties screen in Console to change this setting when disconnected
from the unit. However, DID assignments made in Console must match DID assignments made using the front
panel.

Default

Default restores ALL settings to their factory default values. Answer Yes to the prompt to restore default settings, or
No to retain the existing settings.

WARNING: Using Default resets the unit and restores ALL settings to their
factory defaults, including advanced settings configured using Console.

Contrast

Contrast allows you to change the LCD contrast level. Use the Menu Dial to adjust the contrast level, then press
the Select button to save it.
