DIO Connectors

The GC5050 has 4 connectors. All the connectors are available on the instrument’s front panel.

The GC5050 has the following connectors:

Connector Name

Control signals

Connector Description

J1 I/O

UUT I/O signals

68 Pin VHD Connector

J2 Timing

UUT Timing Signals

68 Pin VHD Connector

J5 I/O

Timing Signals Daisy chained to additional slaves.

20 Pin High Density Connector

J7 Timing

UUT Control Signals. Do not use on Slave.

14 Pin VHD Connector.

 

Connectors J5 (UUT I/O Signals), and J2 (Timing Control Signals) are 68-pin VHD connectors. J7 is 20-pin high-density header that is used to Daisy-chained additional Slave DIOs to achieve a pattern that is wider than 32 channels.

The figure below shows the layout of a 68-Pin VHD connectors used for UUT I/O and timing signals. The 68-pin male end plate connector has a shielded, double pin row receptacle. The connector mates with a UUT cable.

Notes for the table:

●     Pin: Pin number

●     I/O: Input or Output

●     P: Power/GND

●     IO0 – IO31: Differentially Coupled Data Lines. Non-differential I/O Modules, all IOx-(negated) lines are grounded.

●     MS: I/O Module specific, See the “PCI Bus I/O Modules and Interfaces User’s Guide” for complete pin listings for I/O modules.
