Section Six: Commands for RS-232 Control Introduction
INTRODUCTION
The following commands can be used to program A/V programmable remote
control systems allowing the PVI-65 to be operated from a remote device.
All commands begin with an ASCII escape (<Esc>) code (generated using the
Esc key on your keyboard), followed by a forward parenthesis “(”. The initiat-
ing code then appears as follows:
<Esc>(
All other characters which follow this command require a combination of
alphanumeric codes.
X-Y Coordinate Grid
Numerous commands refer to a screen grid with coordinates based on an inter-
nal grid that is 1Ø24 x 1Ø24 units. The grid can be absolute, covering the
entire screen area, or relative to a current position. The absolute grid coordi-
nate of ØØØØØØØØ is at the upper-left of the screen. The grid coordinate of
1Ø231Ø23, then, is in the lower-right. Relative grid coordinates can include
negative numbers to indicate positions above or left of a current position. In
the illustration below, XXXX = a numeric value for the horizontal axis.
YYYY = a numeric value for the vertical axis.
