Rear I/O Solution
The cPCI-743xR cards are rear I/O versions of the cPCI-743x. cPCI-743xR boards must be used with 32-bit CompactPCI backplane with rear I/O connectors on J2. The cPCI-743xR is plug-and-play main board with a rear I/O transition board. The main board is accessed by user in front of the chassis, makes it easy to maintain. The rear I/O transition board is fixed at the back of the chassis. The front panel of cPCI-743xR is equipped with 4 LEDs which are programmable to show the internal status of the board operation.

PNP-type Transistor Output
The default transistor output of the cPCI-7434 is NPN-type current sink Darlington transistors. The PNP-type transistor output version, which is for current source, is available upon request.
