Technobox Part Number 4289

Enhanced Reconfigurable 32-channel
RS485 / RS422 Differential I/O


Technobox P/N 4289 Enhanced 32-channel RS485/422 Differential Digital I/O PMC Reconfigurable Reprogrammable

The Technobox 4289 provides a vehicle for implementing complex user-specific digital designs requiring a differential interface. It is a second-generation design that features 64b/66MHz PCI bus support, up to 66 MHz local bus clock, and a standard 12K Logic Elements (LE) FPGA. The design features a total of 32 general-purpose RS422/RS485 driven digital I/Os wired to both the front panel and rear PN4 connector (64 signals per connector taking into account 2 signals per differential pair). For each of the 32 channels, the bidirectionality is controlled by an output from the FPGA. Local bus clock is selectable as 24, 33, 50, or 66 MHz using resistorjumpers. Any frequency with better than 0.1% accuracy can be generated by the PLL as programmed from the host processor.
