1 Product overview
Figure 1- ADP-3G block diagram
The Flashlink ADP-3GHD is a multi bit-rate ADD/DROP/PASS module providing high
performance media distribution for various signal formats from 19.4Mbps up to 2970Mbps.
The unit can be operated as a redundant or dual ADP amplifier configured to do cable
equalizing and reclocking of SMPTE 424M, SMPTE 292M and SMPTE 259M signal formats.
The four inputs typically provide automatic cable equalizing for up to 70 meters of cable
(Belden 1694A at 2970Mbps), with reclockers on all outputs. The ADP-3GHD will detect
3GHD, HD and SD rates and automatically switch to the correct output slew-rate.
The reclockers support the bit-rates 270Mbps, 1483.5Mbps, 1485Mbps 2967Mbps and
2970Mbps. For other rates, the reclockers automatically switch to bypass mode, and the
ADP-3GHD will work as a non-reclocking distribution amplifier with cable equalizers.
The ADP-3GHD also supports reclocking of DVB-ASI at 270Mbps, enabling all possible rates
including empty transport streams with only K28.5 padding packets. All of the outputs are
non-inverting and suitable for DVB-ASI.
In redundant operation the included intelligent change-over feature gives the ability to
change between inputs based on input signal loss, loss of lock, EDH errors or a combination
of the above.
There is also included a passive bypass function from both inputs to non-inverted outputs
with less than 15 m loss of cable length (enables full redundancy in case of mains failure).
The ADP-3GHD is designed for all distribution purposes in studio, duplication and broadcast
applications.
Please observe that ADP-3GHD can not be used with N-Box, Flashlink one module desktop
box, due to mechanical issues.

3 Configuration
The ADP-3GHD supports a number of different formats. The correct configuration can either
be set with a DIP switch or with the GYDA system controller. The layout of ADP-3GHD is
shown in the drawing below.

DIP switch configuration must be set according to the table below:
All DIP switches are off when pointing towards the release handle.
