WARNING
Operation of electronic equipment involves the use of voltages and currents that
may be dangerous to human life. Note that under certain conditions dangerous
potentials may exist in some circuits when power controls are in the OFF position.
Maintenance personnel should observe all safety regulations.
Do not make any adjustments inside equipment with power ON unless proper
precautions are observed. All internal adjustments should only be made by suitably
qualified personnel. All operational adjustments are available externally without the
need for removing covers or use of extender cards.

Types ADC-3250/OPT & DAC-3250/OPT
Analogue Video & Audio to 270 Mb/s
Fibre Optic Link
General Description
The ADC-3250/OPT and DAC-3250/OPT form an encoder / decoder pair for converting an analogue video, up to 4
channels of audio and an RS-232 data port to a 270 Mb/s digital signal suitable for transport over ASI/SDI paths.
This allows analogue signals to be passed through purely digital environments such as digital optical links and
digital routers and switchers thus simplifying installations that are predominantly digital where some analogue
signals still exist.
When used with IRT’s fibre mux/demux system, both analogue and digital signals can be sent over the same link.
The ADC-3250/OPT encodes the analogue input signals to a 270 Mb/s digital stream. The inputs can either be a
single video, up to 4 channels of audio or a combination of video and audio. There is also an RS-232 data input
port, which can be used concurrently with the video and audio or by itself.
The DAC-3250/OPT decodes the 270 Mb/s digital stream to recover the original signals.
Front panel LED indicators on both units indicate the presence of the analogue and data input signals. The
ADC-3250/OPT allows cable equalisation of various lengths by a front panel control. A front panel monitor output
aids in setting this correctly.
Plug-in fibre optic boards are included on both the ADC-3250/OPT and DAC-3250/OPT for direct connection to a
single mode fibre.
The 270 Mb/s digital signal is of the same data rate as ASI and SDI signals hence its ability to be sent over ASI/SDI
paths. Although similar in structure to both ASI and SDI it is neither of these types of signals. Hence the
ADC-3250/OPT and DAC-3250/OPT are designed to act as an encoder / decoder pair.
Both the ADC-3250/OPT and DAC-3250/OPT are manufactured on extended Eurocard boards and are suitable for
mounting in IRT’s 1RU and 3RU Eurocard frames with other analogue or digital modules.
Standard features:
•
•
1 analogue video, 4 audio and 1 data channel to 270 Mb/s digital stream suitable
for transmission over 270 Mb/s systems, such as digital fibre systems, routers, etc.
Plug-in Fibre Optic Link boards included.

Operation
The ADC-3250/OPT will take an analogue video input and up to four analogue audio inputs plus a unidirectional
RS-232 data signal and encode them into a single 270 Mb/s data stream for interfacing with non-inverting ASI/SDI
links. As with ASI signals, the 270 Mb/s output signal is phase dependent and so should only be used with noninverting links.
Note that if the system is intended for audio or data use only, it is not necessary to also supply an input video signal,
as all inputs are independent of each other.
With the link and switch settings correctly set as in the configuration section of this manual, and input and output
connections correctly wired and cards installed in a suitable frame as in the installation section of this manual,
operation is as simple as connect and turn on.
Front panel LED’s on both the ADC-3250/OPT and DAC-3250/OPT indicate the presence of what inputs are
connected to the ADC-3250/OPT. The DAC-3250/OPT also indicates the presence of a suitably encoded 270 Mb/s
stream. If the optional optical sub board is also fitted to the ADC-3250/OPT, a front panel LED also indicates if
there is a laser failure.
Adjustments
With an ADC-3250/OPT & DAC-3250/OPT pair there is unity gain between the ADC-3250/OPT inputs and the
DAC-3250/OPT outputs. The only user operational settings are on the ADC-3250/OPT front panel for
compensating the analogue video for input cable losses.
With a waveform monitor connected to the Video Mon BNC connector on the front panel, input a known test signal
such as colour bars down the intended input cable. Adjusting both the gain and equalisation controls through the
front panel, using a small flat bladed tweaking screwdriver, can compensate for loss of gain and frequency roll off
caused by the length of input coaxial cable.

the warranty period or not.
Equipment warranty is limited to faults attributable to defects in original design or manufacture. Warranty on
components shall be extended by IRT only to the extent obtainable from the component supplier.
Equipment return:
Before arranging service, ensure that the fault is in the unit to be serviced and not in associated equipment. If
possible, confirm this by substitution.
Before returning equipment contact should be made with IRT or your local agent to determine whether the
equipment can be serviced in the field or should be returned for repair.
The equipment should be properly packed for return observing antistatic procedures.
The following information should accompany the unit to be returned:
1.
2.
3.
4.
5.
6.
7.
A fault report should be included indicating the nature of the fault
The operating conditions under which the fault initially occurred.
Any additional information, which may be of assistance in fault location and remedy.
A contact name and telephone and fax numbers.
Details of payment method for items not covered by warranty.
Full return address.
For situations when “No Fault Found” for repairs, a minimum charge of 1 hour’s labour will apply,
whether the equipment is within the warranty period or not. Contact IRT for current hourly rate.
Please note that all freight charges are the responsibility of the customer.
The equipment should be returned to the agent who originally supplied the equipment or, where this is not
possible, to IRT direct as follows.
