2-44 System Overview
• Interrupt sent by FOINK
The DMB will reset the SBC if it detects an error.
Error Conditions of the DMB sensed by the SBC:
• PLD programming failure
• Loss of +5 or +12 VDC
• Loss of Communications with SBC
• Corrupt FIRMWARE

The SBC communicates with the Host PC via an RS-422 interface. This is a
serial connection capable of transmitting more data than a standard RS-232
port. As it is not a standard serial port a RS-485 card must be installed into
one of the Host PCs expansion slots and the port must be configured correctly
for the PRODIGY to operate correctly (see DXPC2000 chapter 5 appendices).
