PROGRAMMING
System PC Controller Application Software
Advanced control of the system is available by using PC control applica-
tions. Typically users may want to customize the default configurations to
control settings such as frequency, scrambling keys, modulation
parameters, and video resolution.
The transmitter is controlled by the application
DTC_tx_ctrl.exe
avail-
able on the CD delivered with the product.
A PC is required with two RS232 Serial COM ports to control both a
transmitter and receiver simultaneously. Where changes are to be made to
either a transmitter, or a receiver, at different times, a PC with a single
RS232 Serial COM part can be used.
Installation of the two control programs is as simple as copying them from
the CD to a suitable location on the PC. No install shield routine is
launched. Note that the controllers generate their own log and
initialization files, so it is best to create a dedicated directory for these
applications, perhaps with links to the applications from the desktop of
the PC.
Getting Started
•Use the supplied cables to connect the chosen COM port(s) of the PC to
unit(s) to be configured.
•Launch each application in turn by double clicking or using the run
command.
•Connection with a transmitter should be automatic, but the user can
force selection of the correct COM port using the drop down, followed by
the Connect button.
•Errors may appear during the connection process if the PC is unable to
automatically ascertain which unit is connected to which COM port.
