X20

=

Scaler refresh rate

1 = 50 Hz
2 = 56 Hz (1280x768 only)
3 = 60 Hz
4 = 75 Hz
5 = AFL* (50 Hz for PAL or 59.94 Hz for

NTSC)

6 = True rate (72 Hz for NTSC or 100 Hz for

PAL)

7 = not applicable

Using the command/response tables

The command/response tables on the next page list valid command ASCII codes,
the scaler’s responses to the host, and a description of the command’s function
or the results of executing the command. Except when setting audio gain/
attenuation, detail, and sharpness, upper and lower case characters may be used
interchangeably in the command field.

The ASCII to HEX conversion table at left is for use with the
command/response tables.

ASCII to HEX Conversion Table

The command/response tables use symbols (defined below) to represent variables.
