PCI 64 channel digital input/output timing and counting board

The PIO-D64U board is a newly launched product by Hongge that complies with RoHS environmental regulations. The design of the new PIO-D64U is directly compatible with PIO-D64.

PIO-D64U supports 3.3V/5V PCI bus interface and provides 32 TTL compliant digital output channels, 32 TTL compliant digital input channels, and 6 timing and counting channels. It has four built-in Clock Sources, namely 2MHz, 1MHz, 500kHz, and 250kHz. The built-in timer counter provides three channels for frequency measurement, event counting, and pulse generation. The second 8254 provides three channels for interrupt functions.

PIO-D64U has added two new hardware features. The first is the Card ID toggle switch, which allows users to freely set the identifier for each card. When the system uses multiple PIO-D64U cards at the same time, users can quickly and easily distinguish these cards of the same model; The second type is the DI Pull High/Low setting function, where the digital input port can be set to either pull high or pull low. When the signal line drops or disconnects, the DI value will remain relatively high or low (non floating).

Features and Architecture:

• Universal PCI interface, supporting 5V and 3.3V PCI bus slots

• The Card ID function allows users to set the auxiliary identification number of the card to distinguish multiple cards of the same model

• The digital input port can be set to either pull high or pull low. When the signal line drops or disconnects, the DI value will remain relatively high or low (non floating)

• 32 digital input channels

• 32 digital output channels

• Digital I/O response speed can reach up to 1.2 MHz

• A 16 bit timing counter and a 32-bit 4 MHz timing counter

• Three 16 bit programmable independent timing counters

• Software compatible with PIO-D64

• Users can directly apply PIO-DIO series products
