SCXI-1180 Feedthrough Panel
The SCXI-1180 feedthrough panel provides front-panel access to the signals of any data
acquisition board that uses a 50-pin I/O connector. The SCXI-1180 consists of a front panel with
a 50-pin male front panel connector that occupies one slot in the SCXI chassis, and a ribbon
cable with a female rear connector and a male breakout connector. You can attach the rear
connector to the male breakout connector of an SCXI-1340, SCXI-1341, SCXI-1342,
SCXI-1344, or SCXI-1351 in the adjacent slot. The breakout connector further extends the
cabling scheme. The front panel connector provides the feedthrough connection. You can attach
an SCXI-1302 terminal block to the front panel connector for simple screw terminal connections.
A rear filler panel that shields and protects the interior of the SCXI chassis is also included.

SCXI-1180 Installation

Install the SCXI-1180 to the right of a slot that has an SCXI-1340, SCXI-1341, SCXI-1342, or
SCXI-1344 cable assembly or an SCXI-1351 slot extender in its rear connector space.
