The VME Bus Interface is used as an optional connector for compatibility with the GE Fanuc 90/70 Programmable Logic Controllers (PLCs). The board can function as either a VME Bus master or slave. When operating as a VME Bus slave it will do so with an 8K dual-ported SRAM interface. All VME Bus accesses will be controlled in a configurable static random access memory (SRAM) based field programmable array (FGPA) device. 

There are four ways you can reset the DS200DSPCH1A board, you can do a VME sysreset, a power-up reset, use the reset pushbutton, or the VME master bus can write to the VME control register.

Yes the DSPC board has provisions for mounting up to four daughterboards. 

There are two switches. The SW1 is a hard reset switch for the DSP and the SW2 switch is a serial boot switch.

There are six LEDs on the board, two of them are used to indicate the status of the DSPC board, the designation regarding the status are IMOK and FAIL. The IMOK will be green and indicating that the board is functioning properly; the FAIL LED will be red and indicates that the VME Bus has reported that the board has failed. The remaining four LEDs are software-defined but are done so per individual project, they will be Amber and the designations are LED1, LED2, LED3, and LED4.
