The host side connection is PCI based and the external I/O interface is accessible through a 50 pin connector. The external interface includes 24 signals that can be arbitrarily programmed as either input or output. The 24 programmable signals are divided into three groups of eight signals each; Port A, Port B and Port C. Port A and B signals are each programmable as all inputs or all outputs. The Port C signals are individually programmable as input or output. One extra signal can be configured to generate an external clock or used as an additional input. Custom Applications Although the DIO24 provides extensive flexibility to accommodate many user applications, custom interfaces exist which may not conform to current DIO24 interface options. General Standards Corporation has worked with many customers to provide customized versions of the DIO24 and other GSC products. Custom protocols are implemented in an Altera FPGA. Previous custom applications implemented in FPGAs included features for counting pulses, incremental encoders, interrupt generation, special waveform generation, DMA, and many others. Modifications to existing FPGA firmware can be made by General Standards or by the customer if desired. Some other products have been implemented with Xilinx FPGAs and if necessary, a Xilinx version of the board could be developed. Please consult our sales department with your specifications to inquire about a custom application. RS485/422 or ECL Interface The standard interface option utilizes RS422/485 differential I/O transceivers. A version of the PCI- DIO24 is also available with ECL differential I/O transceivers.
