NI-9753

8-Channel C Series Differential Digital I/O Module—The NI‑9753 provides differential digital I/O with RS485/RS422‑compatible transceivers, which is ideal for automotive applications. You can control channels with custom Boolean logic, such as sending fuel and ignition commands, or you can use serial communication protocols. The NI Powertrain Controls Device Drivers software provides functions for engine position tracking and complex engine-synchronous fuel/spark commands. In static direction control mode, you can individually configure all eight channel directions during initialization. In dynamic direction control mode, only four channels are available, but each channel direction is controlled dynamically at run-time with a direction-control Boolean, which is useful for half-duplex serial communications.
