The F215 is a universal interface board based on 3U CompactPCI®. The physical layer can be realized individually for each channel by means of SA-Adapters™.
SA-Adapters™ are small universal boards providing the line drivers for legacy serial I/O, fieldbus interfaces and other small I/O functions. Most SA-Adapters™ use 9-pin D-Sub connectors which are accessible at the front panel. Alternatively, the adapter can be connected to the front panel via ribbon cable. The SA concept allows to add additional I/O interfaces to the F215, enhancing flexibility with regard to the line transceivers and isolation requirements.
Two SA-Adapters™ can be mounted directly on the F215, the other maximum six adapters need more front-panel space and are connected to the carrier via ribbon cable. The F215 comes in a standard configuration with five pre-defined functions on 8 HP: two CAN interfaces, two UARTs and one 8-channel binary I/O interface. SA-Adapters™ are not included in the delivery, because different types are available, e.g. for the UARTs. They can be ordered as needed.
The board's I/O functions are realized by means of an FPGA, making it a very flexible, inexpensive solution for dedicated serial I/O. The card can become "everything" from a customized I/O combination to a specialized 8-port CAN card or even an intelligent I/O board including a Nios® soft core, on 4, 8 or 12 HP. The FPGA is loaded automatically after power-up from a 4 MB serial Flash. It is also possible to access this Flash from the CompactPCI® bus to update its contents.
Optionally also a 32 MB DDR2 SDRAM can be installed to complement the functions of the FPGA. This DRAM can be used for example as a large buffer memory for more complex protocols.
The F215 is designed for use in rugged environments. For example, all components are soldered-on and are specified for an operating temperature of -40 to +85°C.
