Innovate Motorsports OT-2 - Manual (Page 18)

5 Installing an OT-2 with an LC-1 or other MTS
compatible device
1. With
ALL MTS DEVICES OFF (no power) and the OT-2 DISCONNECTED FROM OBD-II,
connect the Serial OUT port from your last MTS device to the Serial IN port on your OT-2
with a suitable patch cable
2. Find the OBD-II connector in your passenger vehicle
3. Plug the OT-2 into the OBD-II port and observe the MTS light.
At NO TIME should the MTS light come on!
If the light comes on steadily for 1 second, then starts blinking, the OT-2 is in the wrong
mode. That is, it believes that it is the ‘head’ unit. If this occurs, UNPLUG the OT-2 from the
OBD-II connector and check all MTS connections. It is sometimes helpful to press firmly and
twist slightly to make sure that the connectors are inserted all the way.
Once the connections have been checked, repeat step 3 until the MTS light behaves
correctly.
4. Start the ignition on the vehicle. Shortly after the ignition is started, the MTS light should start
blinking. This indicates that MTS data is being received from the MTS hardware ‘upstream’
and everything is working correctly. If the light is not blinking, confirm that the other device(s)
are, in fact, receiving power and that the serial connections are all secure and correct
(remember, always power off all units when connecting or disconnecting the serial cables!)
