The DCP (Device Control Protocol) offers three modes, off, control and synchronize. Set the DCP mode
to “Control” if a single QuadraVista will be controlled from an external computer. Set the mode to
“Synchronize” if you system features several linked QuadraVista’s. When in this mode the QuadraVista
status is transmitted to the external computer. For local unit operation, set the mode to off. See the Serial
Operations section for detailed information on the DCP mode.
Use the Disable Channel function to
select the number of channels to
display. If computers are connected to
channel 1, 2, and 3, then select 3.
