The Generic Device Driver  

Chromeleon supports more than 250 Device Drivers for controlling Dionex and third-party instruments. If Chromeleon does not provide a device driver for a specific instrument, you can create your own driver, using a Generic Device Driver.

Enter the required communication parameters, as well as the commands and properties in a Definition file; Chromeleon automatically generates the device driver from this information.

Currently, Chromeleon supports device control via a Generic Device Driver only for instruments that are equipped with an RS-232 port. The reason is that only limited bi-directional support is available. This means that Chromeleon usually does not support all functions of the device because requesting and evaluating instrument status messages is not possible. In addition, only analog data acquisition is supported.

After you have created a new Generic Device Driver, you can install the driver in the Server Configuration program in the same way as any other device driver.
