The PowerCurve, PowerCenter, and PowerTower machines share the same logic board design. These logic boards are autosensing and determine if the monitor is connected to the Mac or VGA port. Video is then automatically sent to the correct port.
There are a few older VGA monitors that are not compatible with this autosensing technology. For this situation we have built onto these logic boards a set of pins labeled VGA Enable. Jumping these pins allows us to designate that video signals be sent to the VGA port only. Power Computing sells only one monitor which needs the jumper in place: the Princeton Mag 14".
See below for illustrations of where the VGA Enable pins are located. There are two possible locations. (All references to locations assume we are viewing the logic board from the front of the computer.)
1) Location 1: Behind the fan cable connection and in front of the external SCSI port.
2) Location 2: To the right of the fan cable connection and in front of the video
connectors.
If the VGA Enable is at Location 1, it should ship with three pins and the jumper across the left two pins. To switch to VGA mode, move the jumper to the right two pins.
If the VGA Enable is at Location 2, it should ship with only two pins and the jumper connected to just one of them. Place the jumper across both pins.
Some systems shipped with no VGA Enable pins. In this case, or in the case that the customer is unable or unwilling to open the case and go inside the machine, Power Computing can send a VGA-to-Mac adapter. However, any VGA-to-Mac adapter will allow non-autosensing VGA monitors to display video on the Mac port.
