Description
The Digital I/O Interface, identified by part numbers 777387-01 and 182920-01, presents a highly versatile platform for interfacing with digital signals. This device boasts 96 channels, providing ample connectivity options for various digital communication needs. With a 24-bit bit depth, it ensures precise data capture and signal integrity.
This Digital I/O Interface is compatible with the NI-DAQmx driver, facilitating seamless integration with existing systems. It features TTL/CMOS compatibility and supports both bidirectional and unidirectional communication, along with 2-wire handshake capability, making it a flexible choice for a wide range of applications.
Embedded within the device are 4 Programmable Peripheral Interface (PPI) chips, enhancing its adaptability to various digital communication tasks. Additionally, it is designed to work in conjunction with SCXI modules and accessories, though these are sold separately, providing further expandability.
The interface includes a programmable interval timer based on the 82C53 model, contributing to its precision timing capabilities. It conforms to the PCI Specification Revision 2.1, ensuring compatibility with a broad range of PCI slots and systems.
Upon power-up, the device’s state is predictable thanks to bias resistors, with a default high state controlled by 100 kΩ bias resistors. This feature aids in maintaining signal integrity from the moment the device is powered on. Connection to external devices is facilitated by a 100-pin I/O connector, and it is designed to operate with the R1005050 compatible cable.
The Digital I/O Interface operates efficiently, with a power consumption of 400 mA. It is built to operate within a temperature range of 0 to 55 °C and can be stored safely between -20 to 70 °C. The device’s compact dimensions, 5.4 x 4.2 in., and light weight of
