Introduction
Features
AJA HD10A HDTV Analog to Serial Video Converter User Manual — Introduction
The HD10A is a miniature, high-quality, 10-bit analog to digital converter for
HDTV. A companion to the popular HD10C2 D/A converter, the HD10A can add
an HD-SDI output to cameras, VTRs, or other analog-only high definition
equipment. The HD10A accepts RGB or YPbPr analog HD and outputs three
duplicate HD-SDI signals. It provides 1080/1035i, 1080p, and 720p with internal
or external sync.

There is an internal jumper used for selecting Bi-level or Tri-level. The jumper is set at the
factory to a default setting of Tri-level sync. To change this jumper setting, follow this
procedure:
Remove the bottom converter cover by removing the screws securing it, and then
sliding it off.
Locate the jumper on the circuit card inside and change it to one of the settings shown
in the diagram below:
