Agilent E1330B Quad 8-Bit Digital Input/Output
The Agilent E1330B Quad 8-bit Digital Input/Output module is a B-size, 1-slot, register-based VXI device. It is a four-port digital input/output module intended for data communication and digital control.
Each 8-bit port is identical consisting of data and handshake/control lines. Each 8-bit port can be configured for output or input and positive or negative true logic. Ports can be combined allowing data transmission using bytes, words (16-bit), and long words (32-bit). Bit data transmissions are also allowed. Three handshake and control lines are provided for each port when using SCPI programming. The flag line from each of the individual ports can be used independently, or they can be combined when using word or long-word data transmission.
Refer to the Agilent Technologies Website for instrument driver availability and downloading instructions, as well as for recent product updates, if applicable.
Handshake and Control Lines
Three handshake and control lines are provided for each port when using SCPI programming. These lines provide the following functions:
-
FLG Flag line.
-
Data handshaking line input to the digital I/O module.
-
CTL Control line.
-
Data handshaking line output by the digital I/O module.
-
I/O Input/output status line.
-
Output line on the module describing the current status of the port.
The flag line from each of the individual ports can be used independently, or they can be combined when using word or long-word data transmission. Each port has three additional control lines available for custom handshaking and interrupt functions.
