	This plug should be removed after connecting the CAN bus to the EMIT panel, since the DCT becomes the new end of the network. This assumes the red switch by the ECU CAN port of the screen is terminated (switched up).

			==Engine Panel Reset==

			In some cases, especially with remote or auto restart, it will be required that the compressor panel reset the faults on the engine panel during the start sequence. See [[ADEM Fault Reset]].

	Except on a few very old panels, the panels will have an IDLE/MANUAL/AUTO selector switch and a manual +/- switch. When in IDLE, the Brain will output the minimum speed, and the IDLE relay will be on. When in MANUAL, the Brain will change the output speed as the SPEED+ or SPEED- switches are held. When in AUTO, the Brain will output the configured auto speed- either a fixed speed, or based off of a sensor condition (e.g. suction pressure). If another manual speed knob exists on the ADEM in this case, it should be unwired and removed to avoid confusion from having two manual speed knobs.

	Note 2: CG-137 has two e-stop loops in parallel that both have to be broken at the same time. For this engine the E-stop needs three contact blocks to add our E-stop to the CAT loop-- two for the CAT loop and one for the Brain shutdown.

For this engine the E-stop needs three contact blocks to add our E-stop to the CAT loop-- two for the CAT loop and one for the Brain shutdown.

			===CAT Setup Notes===

			Some engines have special setup through CAT ET to make sure the start/stop inputs work as intended. If an engine is not listed below it has no special setup for start / stop.
