National Instruments PCI-6533 Digital I/O Device

The PCI-6533, also known as the PCI-DIO-32HS, is a completely jumperless, switchless Digital I/O Device from National Instruments. This model is designed for CompactPCI or PXI chassis and PCI busses. Powered with the NI proprietary MITE PCI interface, the PCI-6533 offers bus-master operation, burst PCI transfers, and high-speed DMA (Direct memory access) controllers.

This Digital I/O Device comes equipped with the NI DAQ-DIO chip. The National Instruments DAQ-DIO chip comes equipped with handshaking, pattern generation, and two separate channels of digital input and digital output. Each channel offers a selectable data path width, 16 and 32-bit counters, a handshaking controller with six timing protocols, 24 mA outputs, a maximum sample rate of 20 MHz, star /stop trigger detection, and more. The Pattern I/O and Handshaking I/O functions of the PCI 6533 allow the user to input or output patterns with timing control.

The 32 digital input/output lines offered by this device are divided as four 8-bit ports. For handshaking or pattern I/O, these ports can be used in configurations of two 8-bits or two 16-bit groups or one 32-bit group. The channels have a maximum rate of up to 2 MHz for pattern I/O, and voltage levels of 5 V TTL/CMOS. The digital transmission on PCI-6533 is managed by a single 68-pin male SCSI-II cable connector. Moreover, this Digital I/O Device enables the users to select power-on states for the data and control lines independently.

This device utilizes the RTSI bus or the PXI trigger bus for receiving and sending trigger and clock signals to and from other connected devices. Thus, the PCI-6533 can also be utilized for the construction of synchronized systems with a massive number of digital input and output lines.

The PCI-6533 operates using the NI-DAQ driver software which is compatible software packages/ application development environments (ADEs) like LabVIEW, LabWindows/CVI, ComponentWorks, or VirtualBench. The device has a recommended operating temperature range of 0 to 55° C. The device measures 6.9 x 4.2 in. in physical dimensions.

PCI-6533 Obsolete Status has been declared by National Instruments, but this device will still be available for purchase and repairs at Apex Waves.
