The VIPER provides +5V to a PC/104 add-on board via the PL11 and PL12
connectors. If a PC/104 add-on board requires a +12V supply, then +12V must be
supplied to the VIPER power connector PL16 pin 4. If –12V or –5V are required, these
must be supplied directly to the PC/104 add-on board.
The VIPER is available with non-stack through connectors by special order. Contact
