Connections

Audio Inputs

The number and configuration of the audio inputs depends on the specific model of ABT you are using.

Reference Input (Looped Through)

An external reference signal is required to synchronize the SDTI outputs. An analog video reference signal, word clock or AES-75 signal can be connected to one of the REFERENCE SIGNAL connectors. If the loop-through is not used, a 75 REFERENCE SIGNAL connector must be used to properly terminate the line.

For an Audio Bridge Terminal with an AES breakout panel, AES INPUT 1 can also be used for synchronization. This input signal must be error-free PCM audio sampled at 48 kHz. In the case where both REFERENCE SIGNAL and AES INPUT 1 have valid references, the signal connected to REFERENCE SIGNAL has priority.

Audio Bridge Terminal

Multiplexed Audio Outputs

The multiplexed audio outputs are formatted to be compatible with the STDI audio input connections on the KXI-16 series of cards.

The Serial Digital Transport Interface (SDTI) uses the Serial Digital Interface (SDI) developed to transport digital video signals as a carrier for other data types. It requires that the transmitter and receiver have the same codec.

Ethernet/Power

The power for the ABT arrives on an RJ-45 connector, and shares this connector with an Ethernet interface. The ABT conforms to the IEEE 802.3af standard for powered devices

Two kinds of power sources are supported:

• midspan power source injector into an existing Ethernet network,

• power sourcing Ethernet switch.

Full redundancy is obtained with both supplies present at the same time.

Indicators

The ACTIVITY indicator is located on the right-hand side of the rear panel. This LED reports the status of the Ethernet connection as follows:

Color Board Status

Off No link detected

Green Normal (good link)

Orange Activity

Red Hardware fault

Flashing Red Upgrading firmware

Two LEDs are visible on the front panel, one for each power supply. When lit, they both indicate the same status:

Color Board Status

Green Normal

Flashing Green Normal, rebooting

Orange Warning

SDTI Link

Audio Inputs

The two SDTI outputs are identical, each including signals from all inputs. Each SDTI output can be connected to a multiviewer SDTI input or to a specific SDTI de-multiplexer. Depending on the number of input connections available, this link transports up to 128 channels of audio. The SDTI streams transport the current IP address of the Audio Bridge Terminal to the receiver. The connection via TCP/IP will give access to the different parameters and status.

Analog Audio Inputs

The analog channels pass through analog to digital converters with 24 bit resolution and a

kHz sample rate. To compensate the level of the analog signal, the 0 dBFS value may be

48 set from +24

dBu to -7 dBu for each channel through the Web page interface.

Digital Audio Inputs

The ABT operates on at 48 kHz-sampled audio signals, and inputs at different sampling rates may not be processed satisfactorily. The validity, user and channel status bits are transmitted alongside the PCM samples. The input error status detected by the digital input

receiver can be monitored by the Web page interface. The non-PCM data will pass unchanged.

Web Interface

To access the Web interface, the ABT must be connected to a local area network (LAN). If the unit's IP address is known, you can access the built-in Web server by entering the address in a Web browser connected to the same network.

If the IP address is not known, it is possible to reset the unit's network configuration. You must set up a simple LAN comprised of:

• one PC running a Web browser

• the ABT to be configured

• a switch for interconnection.

To connect the ABT to the LAN

1 Connect the PC to the switch. 2 Set the PC network configuration with the following parameters:

Static IP address 10.0.0.1

Subnet mask 255.255.0.0

Default gateway 10.0.0.1

3 Apply power to the ABT and make sure it is connected to the switch.

Note: If the switch is Power over Ethernet (PoE) enabled, simply connect it

to the unit using an Ethernet cable. If not, PoE mid-span (‘inserter’) equipment must be placed between the switch and the Audio Bridge Termi na l.

4 Press the RESET button for at least 1 second.

Note: The RESET button is beside the ETHERNET/POWER RJ-45 connector.

The ABT will reboot with the following static network configuration:

The Audio level adjustments are not applicable to ABT models with digital inputs and do not appear on the Web page.

Network Configuration Web Page

The Network Configuration page allows you to configure network parameters.

The MAC address is the unique hardware address attributed to each Audio Bridge Terminal unit. Each unit has a different address, this being the only way to distinguish the units from each other when connected to a network.

The Label parameter gives the unit a label. The label is found in the title of the Web page. It can contain up to 16

through z, uppercase A through Z), numbers 0 through 9, the hyphen (-), the underscore

a (_) and the asterisk (*). If an invalid character is used, an error message will appear. The same label can be used by many units.

characters. Valid characters are from the English alphabet (lowercase

The DHCP parameter activates or deactivates dynamic network addressing. When activated, it allows a server to dynamically attribute an IP address and configuration information to the Audio Bridge Terminal. Normally the DHCP server provides at least the

Audio Bridge Terminal

Web Interface

following basic information: IP address, subnet mask and default gateway. When Enabled is chosen, the static network parameters become unavailable.

The Static IP Address parameter is the IP address used when DHCP is disabled or unsuccessful.

The Static Network Mask parameter is the network mask used when DHCP is disabled or unsuccessful.

The Static Default Gateway parameter is the default gateway used when DHCP is disabled or unsuccessful.

Note: When DHCP is enabled, the Audio Bridge Terminal will try to obtain

an IP address dynamically after booting/rebooting. If successful, the new IP address, subnet mask and default gateway can only be known by the equipment receiving the SDTI signal because the network configuration addresses are embedded in the Source Address field of the Header Data of the stream (refer to SMPTE 305.2M-2000). If unsuccessful, the static network configuration will be used but DHCP will remain enabled. If the unit is rebooted and a DHCP server responds, it will then use the dynamic network configuration provided by the server.

At any time, it is possible to return to a known static network configuration by pressing the reset button for at least 1 second. It can found in a small hole named RESET just beside the ETHERNET/POWER RJ-45 connector. The ABT will reboot with the following default static network configuration:

Parameter Value

DHCP Disabled

IP address 10.0.3.190

Subnet mask 255.255.0.0

Default gateway 10.0.0.1

Note: The changes are applied when you click Apply & Reboot. A new Web

page appears reminding the new IP address if DHCP is disabled.

If changes to parameters are made before clicking Apply & Reboot and the user wishes to re-establish the values displayed when the page was loaded, this can be done by clicking Cancel Changes.

Finally, factory default values for all parameters on this page can be displayed by clicking Factory Defaults. The default Label is comprised of the ABT type (number of channels and the letter A for analog inputs or D for AES inputs) followed by the last part of its serial number. The default network configuration is the same as the one obtained by pressing the RESET button near the ETHERNET/POWER RJ-45 connector. Click Cancel Changes to return to the values displayed when the page was loaded. Click Apply & Reboot to apply the displayed values. The unit then reboots.

Information Web Page

The Information Web page gives model and version information.

• The model is made up of “ABT-” followed by the number of channels and the letter A for analog inputs or D for AES inputs.

• The serial number is the serial number of this ABT unit.

• The firmware version is the current firmware version. The device connected to this ABT will check the version before updating the firmware.

Firmware Updates

Firmware updates for the ABT are issued occasionally, with the release of a new version of the Kaleido-X Software. The firmware update package, including the MIU utility, is provided on the Kaleido-X upgrade DVD, or can be obtained by contacting Grass Valley Technical Support.

To determine if you need to update your ABT, check its firmware version (see Information

Web Page, on page 13), and compare it with the version of the firmware update file (see the

Software and Firmware section, in the Kaleido-X Release Notes).

The firmware of the ABT can be updated over its Ethernet connection.

Notes

• Before starting the upgrade procedure, make sure there is no other device

• You need to have the Java Runtime Environment version 1.4.2 or later

The Miranda Interface Updater is stored on the Kaleido-X upgrade DVD in a folder named

ABT Upgrade. The folder contains a JAR file (MIU.jar) with the Miranda Interface Updater

(MIU) utility, and a ZIP archive (
