By setting aside a block of memory in the PC, the PCI-1755 performs bus-mastering data transfers without CPU intervention, setting the CPU free to perform other more urgent tasks such as data analysis and graphic manipulation. The function allows users to run all I/O functions 8 simultaneously at full speed without losing data. eConnectivity The messages can be generated when1.

This practical function eliminates danger caused by misoperation during unexpected system reset. On-board FIFO Memory The PCI-1755 provides an onboard FIFO (First In First Out) memory buffer, storing up to 16K samples for digital input and 16K for digital output conversion. Pattern Match Function The PCI-1755 provides a “Pattern Match” interrupt function for digital input channels. The card monitors the states of digital inputs and compares them with a pre-set pattern. When the received state matches the pre-set pattern, the PCI-1755 generates an interrupt signal to the system. Change of State Function A "Change of State" interrupt function is provided at digital input channels. When any signal line changes its state, the card generates an interrupt to the system to handle this event Applications § High speed IC function test § Parallel data transfer § TTL, DTL and CMOS logic signal sensing § Relay and switch monitoring and controlling § Indicator LED driving PCI-1755 I/O Connector Signal Description Signal Name Reference Direction Description PA00~PA07 GND I/O Port A bi-directional DIO channels PB00~PB07 GND I/O Port A bi-directional DIO channels PC00~PC07 GND I/O Port A bi-directional DIO channels PD00~PD07 GND I/O Port A bi-directional DIO channels DI_ACK GND Output Acknowledge line for digital input channels DI_REQ GND Input Request line for digital input channels EXT_CLKIN GND Input Clock input channel DI_STR GND Input Start trigger line for digital input channels DI_STP GND Input Stop trigger line for digital input channels DO_ACK GND Input Acknowledge line for digital output channels DO_REQ GND Output Request line for digital output channels EXT_CLKOUT GND Output Clock output channel DO_STR GND Input Start trigger line for digital output channels DO_STP GND Input Stop trigger line for digital output channels DIO0~DIO7 GND I/O General-purpose digital input/output channels GND - - Ground reference for all other signals Plug-in DA&C Cards Online Download www.advantech.com/products 5-26
