Multiple Agilent MCCD Configuration

1 - General Information

Additionally, a single supply of sufficient amperage may be shared among multiple mainframes that are connected to a common power bus - provided that the total current can be supplied while meeting the voltage specification at the power bus terminals at the rear of the Agilent MCCD.

NOTE: If the external dc power source has an overvoltage protection circuit, it must be set higher than 30 volts to avoid the possibility of shutting itself down during the discharge cycle.

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.
