Generic Device Driver
The "Standard Device" Device Type

The Standard Device device type is the basic type for all other types.

As drivers communicate with external instruments, Chromeleon assumes that the communication with the instrument is explicitly enabled and disabled. To do so, Chromeleon uses the Connect and Disconnect functions. In addition, the Reset function is optionally defined.

• Connect: Enter the command string for switching the instrument into the remote mode. When the server is started, Chromeleon automatically performs the Connect function for all serial instruments. This action ensures that user-defined instruments are reset to the serial remote mode after restarting the server and that the instruments can be immediately addressed using commands, for example, after a power failure.

After successfully completing the Connect command sequence, the action specified in the default settings (see  Setting the Defaults (Property Defaults)) is performed for each property.

• Disconnect: Enter the command sequence for switching the instrument to the manual mode. This function is called upon closing the server down to make all instruments accessible for the manual mode.

• Reset: Enter the corresponding command sequence to set the instrument to a defined status in the event of an error.
