Turbo PMAC PCI Lite
36 E-Point Jumper Descriptions
E98: DAC/ADC Clock Frequency Control
E Point and
Physical Layout
Location Description Default
E98 A4 Jump pin 1 to 2 to provide a 2.45 MHz DCLK
signal to DACs and ADCs.
Jump pin 2 to 3 to provide a 1.22 MHz DCLK
signal to DACs and ADCs. Important for high
accuracy A/D conversion on Acc-28.
1-2 Jumper installed
Note: This also divides the phase and servo clock frequencies in half. See E29-E33, E3-E6, I10
E100: Output Flag Supply Select
E Point and
Physical Layout
Location Description Default
E100 A3 Jump pin 1 to 2 to apply analog supply voltage
A+15V to U37 flag output driver IC.
Jump pin 2 to 3 to apply flag supply voltage
OPT+V to U37 flag output driver IC.
1-2 Jumper installed
E101 - E102: Motors 1-4 Amplifier Enable Output Configure
E Point and
Physical Layout
Location Description Default
E101 A7 Jump pin 1 to 2 to apply A+15V/A+V (as set by
E100) to pin 10 of U37 AENAn & EQUn driver
IC (should be ULN2803A for sink output
configuration).
Jump pin 2 to 3 to apply GND to pin 10 of U37
(should be UDN2981A for source output
configuration).
Caution:
The jumper setting must match the type of driver
IC, or damage to the IC will result.
