Introduction

Marvin Test Solutions provides I/O Modules as interface adapters to meet special interface needs. I/O Modules are daughter cards that mount onto GC5050 DIO boards.

The table below identifies Marvin Test Solutions’s family of I/O Modules. These are part of the DIO system and connect to the parent GC5050 via two 80-pin headers. Two standoffs provide mechanical rigidity. The boards interface with UUTs and external test equipment through the UUT cabling using 68-pin connectors.

I/O Module Application

One I/O Module daughter card is required for each GC5050 board and is specified when the GC5050 is ordered.

I/O Modules are factory mounted on the GC5050 board. The default GC5910 card provides TTL levels. Should interface requirements change, alternate I/O modules can be purchased and installed. Only the I/O Module is changed. You can select an appropriate card type for a UUT interface. Basic DIO main boards are reused.

Specific I/O modules are discussed in the topics:

GC5910 TTL I/O Module, and GC5930 Programmable Level I/O Module.
