The various I/O connections are described below. The connection diagram are to the right, along with wire colours to aid you in connecting the 2J2 to your vehicle. Just remember not to short out any of the unused wires against battery voltage or GND.
On the top of the case (with the sticker) can be found ..
- Status LED - Displays information about sensor function, and indicates errors and alarm conditions.
- CAL Button - When held down, initiates the Auto-cal sequence (indicated by a series of sharp flashes on the status LED) .
- Power Cable - is normally wired to the vehicle's power via a high current (5 Amp) in-line fuse and then to a switched power point. Power is normally made available when the ignition is switched to ON. We discourage temporary installations using a cigarette lighter because the sensors should always be powered when exposed to exhaust gasses.
- Serial sockets - these sockets provides ground, RS232 communications, and current limited power for a Tech Edge display such as LX1 or LA1.
Wideband output
The wideband output voltage can be configured using the config utility, the default setup is shown in the graph below.
Simulated narrowband output
Just like the wideband output the simulated narrowband output can be configured to suit your ECU.
