Figure 2-4. Typical Hardware Connections

RS-232 Connections

The Agilent MCCD has two RS-232 ports for connection to local peripherals. Under normal operation both ports are available for general purpose communications and are configurable over the LAN. For initial configuration and calibration, the RS-232 ports are used as follows:

Initial

RS-232 port B is connected to a terminal and used to access the Agilent

Configuration

MCCD Configuration Screens. This sets up the initial configuration.

Calibration

RS-232 port B is connected to a terminal and used to access the Agilent

 

MCCD Configuration Screens through which the calibration process is

 

executed. RS-232 port A is used to connect a dedicated voltmeter for

 

calibration.

Both ports should be configured with the same baud rate as the computer. Both ports support full hardware flow and software flow control with XON and XOFF support, and with RTS / CTS available for hardware control.
