Technical Description

The E1330B Quad 8-Bit Digital I/O Module (referred to as the Digital I/O

module) is a four port digital input/output module intended for data

communication and digital control in electronic environments. The Digital

I/O module is compatible with TTL levels (0-5V) or CMOS levels (using

external pull-ups). The Digital I/O module complies with VXIbus (VMEbus

Extensions for Instrumentation) definitions for the P1 bus connector on

B-sized modules. A jumper on the module sets the VXIbus interrupt level.
