The pin numbers of the Digital I/O connector appear on the screen. Refer to Figure 2-2 for the physical locations of the pins. Note that the two pins on each end of the connector are the Common connection for any pins that are configured as grounded outputs All pins do not have to be configured in the same way. Some can be used as isolated outputs while others are single-ended I/O. Functions can also be mixed, with some pins being general purpose Digital I/O while others have a specific purpose. Chapter 2 under “Digital Connections” provides further information about the purpose and application of the digital I/O signals. Any pin can be configured for selections 1 through 7. The common ground pin is the return for these selections Accessing Calibration Mixed Configuration ExampleBrowser Settings Agilent MCCD User InterfaceDescription PC RequirementsUsing the Interface AccessLocalization Using the Agilent MCCD Measurement Log Utility Transfers all of the logged data in the order that it was logged Programming Overview A Cell Forming OverviewCell Forming Example Figure 5-1.
