Video Outputs
Two BNC composite video outputs are present on the rear of the unit.
Audio Outputs
There are 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 the audio as one stereo, a dual-
mono or two independent mono channels.
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 bit/s to 115200 bit/s.
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.
ASI Output (Option)
A single ASI output is available if the hardware option
TT1222/HWO/ASI/OUT is purchased.
More detail on the option modules can be found in
Chapter 3, Options.
