6.15.2. Remote Operation Using the External Serial I/O

6.15.2.1. Terminal Operating Modes

The Model GFC 7000TA can be remotely configured, calibrated or queried for stored data through the serial ports. As terminals and computers use different communication schemes, the analyzer supports two communicate modes specifically designed to interface with these two types of devices.

∙Computer mode is used when the analyzer is connected to a computer with a dedicated interface program such as APICOM. More information regarding APICOM can be found in later in this or on the Teledyne Instruments website at http://www.teledyne-api.com/software/apicom/.

∙Interactive mode is used with a terminal emulation programs such as HyperTerminal or a “dumb” computer terminal. The commands that are used to operate the analyzer in this mode are listed in Table 6-26.

Erases one character to the left of the cursor location.

Erases the entire command line.

This command prints a complete list of available commands along with the definitions of their functionality to the display device of the terminal or computer being used. The ID number of the analyzer is only necessary if multiple analyzers are on the same communications line, such as the multi-drop setup.
