Page 4: Introduction
1. Introduction The DSP-22-2 detector is intended to be a two-channel detector that can work with both inductive loops as well as the new Diablo Control Mini-Loop Probe. The detector is powered by a high-performance 8-bit microcontroller that does not skimp on performance. The DSP-22-2 detector has a small footprint and was designed to directly plug into many DoorKing operators. -

(DIP switch 1 OFF and DIP switch 2 OFF). Like most inductive loop vehicle detectors, the DSP-22-2 directly measures the change in frequency of the loop and from there, calculates the change in inductance when a vehicle interacts with it. The change in inductance is measured as %ΔL/L (reads as “percent delta L over L”). -
Page 9: Channel 1 - Frequency (S3 Dip Switches 1 And 2)
The main variables for inductive coupling are loop size, distance between loops, and the loop frequency. Loops that are connected to the same DSP-22-2 detector can not interfere with each other, as the detector will only turn on one of the loops at any point in time (this is referred to as scanning). -

Page 12: Indicators
Channel 2 Low Indicators The DSP-22-2 is equipped with three (3) LED indicators: Power (Green), Detect 1 (Red), and Detect 2 (Red). Power LED – The green power LED indicates these possible states: The voltage applied to the detector is less than the minimum display voltage of approximately 3 volts. - Page 13 Output 2 is not activated the LED shall display the flicker indication. The flicker display is a very fast flashing at a lower level of brightness. In the Pulse mode this DSP-22-2 User Manual Page 13 of 25 DSP-22-2_MAN_A...

Page 16: Detector Installation
Location: The detector should be plugged in to the appropriate connector on the DoorKing operator. Mounting: The detector will function when mounted in any orientation. Using the two holes in the detector, secure the detector in place. DSP-22-2 User Manual Page 16 of 25 DSP-22-2_MAN_A... -
Page 17: Loop Installation
If the installation requires the detection of motorcycles as well as vehicles, the loop should go to within one foot of the curb or roadway edge, whichever is present. If only motor vehicle detection is required, within three feet of the curb or roadway edge is all that is required. DSP-22-2 User Manual Page 17 of 25 DSP-22-2_MAN_A... - Page 18 This will also help remove dust from the saw cutting operation from the sides of the saw slot. This will allow better adhesion of the loop sealant to the saw slot. DSP-22-2 User Manual Page 18 of 25...

Once the loop wire leaves the saw slot it should be twisted at least three times per foot. More is better. The twists should be kept tight to be most effective in reducing the effects of electrical interference.

The probes must be wired in series. DSP-22-2 User Manual Page 21 of 25...

Page 24: Detect Led Will Not Come On With A Vehicle Present
The first thing to do is verify that the LED in question is still working. This is accomplished by a quick lamp test. Reset the detector by pressing the RESET button. All three LEDs should turn off and turn on. If a Detect LED does not illuminate, replace the detector.
