Introduction

1.2.3.2 Audio Outputs

The TT1222 Receiver has two audio outputs available on 9-way D-sub connectors

at the rear panel. Each connector provides one balanced analogue audio pair and

one unbalanced digital signal. Dependent on the input, the user can configure the

analogue output to present each audio as one stereo, a dual-mono or two

independent mono channels.

1.2.3.3 Data Output

RS-232 asynchronous low speed data output carried on a 9-way D-sub connector,

available on all models. The data output rate is configurable from 75 bps to

115200 bps.

1.2.3.4 Relay / GPO Output

The unit can be set up to produce warnings and alarms when particular conditions

occur.

The relay output can be set up to trigger on one or more ‘error’ states. When the

equipment has detected an error, the relay is triggered and the front panel alarm

LED is also activated. For instructions on configuring the alarms, see Chapter 6,

Alarms/GPOs. For a description of the alarm relay, see Chapter 2, Installing the

Equipment.

The same connector supports five GPOs (General Purpose Outputs). These can be

set up to trigger on a single or numerous events. These signals are independent of

the relay signal.

1.2.3.5 ASI Output (Option)

A single ASI transport stream output is available on the rear of the unit if the

hardware option TT1222/HWO/ASI/OUT is purchased.

1.2.3.6 ASI/SDI Outputs (Option)

Two configurable ASI/SDI outputs are available if the hardware option

TT1222/HWO/ASI/SDI is purchased. Each output can be individually configured to

be either ASI or SDI.

1.2.3.7 IP Outputs (Option)

Two IP transport stream outputs are available if the hardware option

TT1222/HWO/IP/OUT is purchased.

More detail on the option modules can be found in Chapter 3, Options.
