34 E-Point Jumper Descriptions
E72 - E73: Panel Analog Time Base Signal Enable
E Point and
Physical Layout
Location Description Default
E72 A9 Jump pin 1 to 2 to allow V to F converter FOUT
derived from wiper input on J2 to connect to
CHA4. No jumper installed
E73
A9 Jump pin 1 to 2 to allow V to F converter FOUT/
derived from wiper
input on J2 to connect to
CHA4/.
No jumper installed
Note: With these jumpers ON, no encoder should be wired into ENC4 on JMACH1. E27 must connect pins 1 to
2 because these are single-ended inputs. To create a positive voltage (frequency) number in PMAC, set variable
I915 to 4.
E74 - E75: Clock Output Control for External Interpolation
E Point and
Physical Layout
Location Description Default
E74 A9 Jump pin 1 to 2 to allow SCLK/ to output on
CHC4/. No jumper installed
E75 B9 Jump pin 1 to 2 to allow SCLK to output on
CHC4. No jumper installed
Note: SCLK out permits synchronous latching of analog encoder interpolators such as Acc-8D Option 8.
E85: Host-Supplied Analog Power Source Enable
E Point and
Physical Layout
Location Description Default
E85 B5 Jump pin 1 to pin 2 to allow A+14V to come from
PC bus (ties amplifier and PMAC power supply
together. Defeats OPTO coupling.). No jumper
Note: If E85 is changed, E88 and E87 must also be changed. See E90.
