Accessories
All outputs are Active Low (DIS 8 supplies ground) Limited to 5 amp
maximum.
Window RPM switch Output- This output is set with the handheld controller, in the RPM
window HI and the RPM window LO. At the Window RPM LO set point the DIS 8 will
ground the RED wire pin “A” on the Accessories Harness at the set RPM activating an
electrical device. On the Window RPM HI set point the DIS8 will deactivate the ground,
turning off the device activated with the RPM LO setting. Example: Use this function to
turn on and off a nitrous solenoid at a set RPM.
RPM switch #2 Output- With this output the DIS 8 will ground the Black wire pin “B” on
the Accessories Harness at the set RPM activating an electrical device.
RPM switch #3 Output- With this output the DIS 8 will ground the Orange wire pin “C”
on the Accessories Harness at the set RPM activating an electrical device.
All Inputs require +12 volts to operate
Retard #1 Input – Supplying 12 volts to the Yellow wire pin “D” on the Accessories
Harness will cause the DIS 8 to retard the timing by the amount of degrees set. When
12 volts is removed this function is deactivated. Example: Use this function to retard
timing when nitrous solenoid is activated.
Auxiliary RPM Limit #2 Input – Supplying 12 volts to the Purple wire pin “E” on the
Accessories Harness will cause the DIS 8 to limit RPM to the AUX RPML 2 set point.
When 12 volts is removed this function is deactivated. Example: Use this function to
limit RPM during the burn out.
Auxiliary RPML Input- Supplying 12 volts to the White wire pin “F” on the Accessories
Harness will cause the DIS 8 to limit the RPM to the AUX RPM set point. When 12 volts
is removed this function is deactivated. Example: Use this function to limit RPM while
on the trans brake.
*Note: Use only the Rev limiters built into the DIS 8. If you use a rev limit from
another source (like GEN 7) the DIS 8 will loose the Cam Synchronization causing DIS
8 to stop firing until the next cam sync pulse is received.
