Computer interfaces
This section describes the RS-232, GPIB, and USB interfaces.
RS-232 interface
Each generator has a standard RS-232 serial connector, labeled “Serial.” This is a 9-pin
D-Sub male connector which enables you to connect the generator with a computer. A null
modem cable is provided to support this interface. You can communicate with the
generator either through the command line interface from a telnet session or from the
Video Generator Manager (VGM) application. The pinouts for the RS-232 connector are
shown in the following table.
GPIB interface (optional)
The GBIP interface allows you to use the generator as a programmable video signal
source in a larger automated test system. Generators that have the GPIB interface option
have two rotary switches for setting the GPIB address. These switches are accessible
through the ventilation slots. The GPIB connector pinouts are listed in the following table.
USB interface
Use the USB interface for downloading bitmap images from a computer. With VGM 4.0 or
later, the USB interface can be used in place of the serial interface.
