WARNINGS & IMPORTANT INFORMATION
Take heed of these warnings which concern the VIPer807:
Warning: CPU Voltage Selection
W1 jumper selects CPU voltage (shorted = 5V, open = 3.3V). Incorrect CPU voltage can
damage your CPU!
Warning: SCSI Connector and Flat Panel Connector Appear Identical
Careful attention should be taken when connecting SCSI or Flat Panel cables to the
VIPer807 board, since both the J7 SCSI connector and the J8 Flat Panel connector are 50-
pin headers. Faulty connections will damage the VIPer807 board!
Warning: Flat Panel Control Signals and the Feature Connector
When the voltage level for the Flat Panel Control signals is set at 3.3V via the W29 jumper,
only 3.3V logic levels can be used for the Feature Connector.
Warning: Flat Panel Power
The VIPer807 only supplies the Flat Panel with 5V power. In order to supply 3.3V power to
your Flat Panel, an external 5V to 3.3V DC-DC voltage converter is required. Incorrect power
voltage can damage your Flat Panel!
Warning: Flat Panel Cable Length
The Flat Panel Cable for the VIPer807 should be cut on the unconnected end to a recommended
maximum length of 18 inches from the high density connector. Though some Flat Panels may
support longer flat cables, and TEKNOR has made allowance for this by providing more than
18 inches of cable, it is the customer's responsibility to ensure that the additional length is fully
supported by the Flat Panel's specifications.
