range for each register. Each command ( i. e. Register Number Byte, followed by Value Byte) must be concluded with
a Carriage Return.
The Value Byte provides “absolute information” if the parameter in question is a Toggle or Multiple Choice Item. If
the parameter in question is a range item, the Value Byte provides “relative information” incrementing or
decrementing the existing value of that parameter by on count.
In addition to the above commands, two additional commands are provided for control information. Writing Value
Byte = 01 to register 22 will cause an Auto Reset operation to occur. Writing Value Byte = 01 to register 23 will cause
the existing parameter set to be written in to NOVRAM. The TView Pro AV 1600 will power up with these parameters
until the NOVRAM is changed by writing another set of parameters.
The following table indicates the Register Functions, the Register Number, Parameter Type and action of the legal
values of the Value Byte.
