26 Configuring the Agilent E1330B Digital I/O
Chapter 2
Connecting to a GPIO Peripheral
The GPIO interface is a widely used standard parallel interface for
connecting computers to peripherals. The GPIO interface may employ up to
32-bits of bi-directional data transfer. The Digital I/O module and the GPIO
interface have identical line definitions but different pin assignments.
Ports A-D on the GPIO are defined as ports 0-3 on the Digital I/O module.
Procedure 1. Connect the ribbon cable to connector J1 and/or J2 on the Digital I/O
module.
2. Connect the wires on the ribbon cable to the peripheral as described
in Table 2-1 for the GPIO interface.
