Chapter 1 Getting Started

This section describes the RS-232, GPIB, and USB interfaces.

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.

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.

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.
