Operation
3.1
General
The V6153 is a combination of two PCBs; a main baseboard and an IO sub-module.
The V6154 is a combination of three PCBs; a main baseboard, and two identical IO sub-
modules.
The main baseboard provides all the power distribution and DART remote control logic, while
the sub-modules take the SDI input and provide all the outputs.

Link Setting
A link is used to enable or disable the re-clocker on the main module. The link setting is defined
here:
Pos 2-3
Pos 1-2

ASI Signals
Although the V6153 and V6154 are essentially SDI DAs, they can be used for ASI signals on
some outputs. The main difference between an ASI signal and a pure SDI signal is that SDI is
polarity independent while ASI signals are not. (There are other technical differences, but this is
the critical one which directly affects the signal integrity.)
Half of the outputs do have the correct polarity, and can safely be used for ASI signals as shown
here:
