Innovate Motorsports DL-32 - Manual (Page 7)

- 7 -
As part of the DL-32 package you will have received a LED, a push-button switch, and a stereo
3.5mm cable with three stripped ends. The cable can be extended with shielded stereo wire up to
30 feet. This kit is the record button and indicator. The installation of this is required if you do
NOT have an XD-16 connected in the log-chain after (chained to SERIAL OUT) of the DL-32.
1. The drill size recommended for mounting the included momentary switch is a 25/64” drill.
2. Optionally, any momentary (Normally Open) push button switch may be used.
3. The included LED will fit the following hole size and panel thickness: a 5/32” (0.155” -
0.158”) hole size and a panel thickness of 28–16gauge (0.031” - 0.062”).
4. Optionally, any 1.2V - 2.2V (1mA- 30mA) LED may be used. A typical LED has 2 wires
called Anode and Cathode. The Cathode side is typically the shorter of the 2 wires or the
black wire..
The following diagram shows how to hook the supplied switch and LED to the cable:
Electrically the schematic looks like this:
3.2 Connecting power to the DL-32
The DL-32 needs to be powered from the car. a switched 12V supply (switched on when the cars
ignition system is on) to the connection marked 12V on the left side. Connect the connection
marked GND to the cars engine block as ground.
3.3 Connecting external sensor signals
For each external connection you can connect the external sensor’s output to the CHx+
connection. Connect the CHx- connection to the ground of the sensor. Make sure the sensor
output signal does not exceed 5V. The DL-32 is protected if sensor signals exceed that (up to
40V for most inputs), but it cannot measure beyond a 5V signal.
