The device can be controlled via DCP (Device Control Protocol), an XML-based protocol. A detailed
description can be found in Appendix E.
There are two DCP modes:
■
DCP
control
, which allows external control of the display mode; and
■
DCP
synchronize
, which keeps several QuadraVista QF devices in the same display mode.
The default setting is
off
, which prevents any external control.
Use a serial or a USB cable to connect a control unit to the RS-232 port (RJ 45) on the QuadraVista QF’s rear
panel. To synchronize several devices, special “Y” cables are required.
Settings for the connection are:
■
transfer rate 57600 baud
■
8 data bits
■
No parity
■
1 stop bit
■
No flow control
The two control modes operate as follows.
