Figure 1-6. Automation Inputs
1.10.1. AUTOMATION
INPUTS
These are contact closure inputs to remotely control the XD10P. There are automation inputs for each of
the eight XD10P operating modes, and a “Mute” input. These are intended to be momentary (or “pulsed”)
contact closures. The “Mute” function is released by selecting (or re-selecting) one of the main input
modes. The Automation common terminal is isolated from the system ground through a 10-ohm resistor
to minimize ground loop problems.
Do not connect circuit ground to chassis (earth) ground.
1.10.2. AUTOMATION
This 25 pin D-type connector contains most of the automation input and output signals. The pinout
specification for this connector is in Appendix A.
1.10.3.
Automation LED Outputs
These are active-low outputs that can directly drive remote LEDs for monitoring the status of the XD10P.
The outputs are current limited, however an additional 1 kilohm resistor in series with each LED (at the
LED) is recommended in case of wiring faults. See the pinout specification for the Automation connector
in Appendix A.
1.11. Other Connections and Controls
1.11.1. Power
Input
The XD10P uses an external 16 VAC @500mA power supply to power the bypass circuit.
1.11.2.
REM FADER (Remote Fader)
The XD10P features a Remote Fader connection on the rear. The two-button remote fader device is not
supplied by DTS. (It can easily be obtained from any electronics supply store.)
Each tap on the UP button will increment 0.1 level. So starting at 7.0, one tap will increment to 7.1. A
tap on the DOWN button will decrement to 6.9. The Remote Fader level range is from 4 to 9. The front
panel will display the level increment/decrement as it occurs.
See the wiring diagrams in Appendix B for identification of the XD10P Remote Fader connection.
1.11.3. C/O
(Changeover)
The XD10P includes dual preamplifiers for use in two projector changeover systems. Grounding the
“C/O” terminal mutes the Projector 1 input and selects Projector 2. This must be a maintained closure.
See the wiring diagram F205 in Appendix B for identification of the C/O connection.
