17. 0 Cable Assembly The SCXI 1340 cable assembly consists of a 50 conductor ribbon cable that has a mounting bracket at one end and a 50 pin female connector at the other end The female connector connects to the I O connector of a plug in board or instrument Attached to the mounting bracket is a 50 pin female mounting bracket connector that connects to the module rear signal connector To extend the signals of the plug in board to another module you can use the male breakout connector that is near the mounting bracket on the ribbon cable All 50 pins from the plug in board go straight through to the rear signal connector You can use a standard 50 pin ribbon cable instead of the SCXI 1340 cable assembly The 5 1 1340 has the following advantages over the ribbon cable e The SCXI 1340 provides strain relief so that you cannot accidentally disconnect the cable e The SCXI 1340 includes a mounting bracket that mounts to the chassis so that you can remove and reinsert the SCXI 1181 without explicitly removing the cable from the back of the chassis This is especially useful when the SCXI chassis is rack mounted making rear access difficult e The SCXI 1340 has an extra male breakout connector for use with the SCXI 1180 feedthrough panel or additional modules that require a direct connection to the plug in board e The SCXI 1340 rear panel gives both mechanical and electrical shielding National Instruments Corporation 1 SCXI 1180 1181 User M
