Turbo PMAC PCI Lite
4 Hardware Setup
HARDWARE SETUP
On the PMAC, there are many jumpers (pairs of metal prongs), called E-points. Some have been shorted
together; others have been left open. These jumpers customize the hardware features of the board for a
given application and must be setup appropriately. The following is an overview of the several PMAC
jumpers grouped in appropriate categories. For a complete description of the jumper setup configuration,
refer to the Turbo PMAC PCI Lite E-Point Jumper Descriptions section of this manual.

E85, E87, E88: Analog Circuit Isolation Control – These jumpers control whether the analog circuitry
on the PMAC is isolated from the digital circuitry, or electrically tied to it. In the default configuration,
these jumpers are off, keeping the circuits isolated from each other (provided separate isolated supplies
are used).
E89-E90: Input Flag Supply Control – If E90 connects pins 1 and 2 and E89 is ON, the input flags
(+LIMn, -LIMn, HMFLn, and FAULTn) are supplied from the analog A+15V supply, which can be
isolated from the digital circuitry. If E90 connects pins 1 and 2 and E89 is OFF, the input flags are
supplied from a separate A+V supply through pin 9 of the J9 JEQU connector. This supply can be in the
+12V to +24V range and can be kept isolated from the digital circuitry. If E90 connects pins 2 and 3, the
input flags are supplied from the d12V supply and isolation from the digital circuitry is defeated.
E100: AENA/EQU Supply Control – If E100 connects pins 1 and 2, the circuits related to the AENAn,
EQUn, and FAULTn signals will be supplied from the analog A+15V supply, which can be isolated from
the digital circuitry. If E100 connects pins 2 and 3, the circuits will be supplied from a separate A+V
supply brought in on pin 9 of the J9 JEQU connector. This supply can be in the +12V to +24V range, and
can be kept isolated from the digital circuitry.
