Please note: 2J1 has a 1 m (approx 3') cable to the sensor. It has a 1 m power cable, and a 1 m RS232 and data cable. Sensor cables are around 0.5 m long so the distance from the sensor to the 2J1 is about 1.5 m and the distance from the sensor to the end of the power cable is 2.5 m (over 8'). Our displays typically have 1.8 m cables so the display can typically be placed 3.3 m (over 12') from the sensor. This means our standard 2J1 and displays will work in most vehicles.

We do NOT sell a 2J1 with a longer cable (ie. one size fits all!). But, we can customise 2J1 for purchase quantities of 25+ (lead times apply).
(*) The older (and more expensive, but no better) 6066 sensor will work with the 2J1 (autocal range allows this for most 6066 sensors) but the connector end must be replaced - we do not do this for individual orders, but it can be arranged for larger orders (25+). We don't recommend, nor support, this modification! 2J will NOT work with the LSU 4.9 sensors.

2J1 USER MANUAL

2J1 Inputs & Outputs

Please note that this documentation is subject to change.

2J1 differs from other Tech Edge wideband units in not having a removable cable between the sensor and controller. It's also designed to be installed in a cool part of a vehicle's engine bay (but remember the case is ABS plastic, it will melt near an exhaust pipe). Even installed underneath a vehicle is possible, although direct exposed to the elements is not recommended. 2J1 features a conformally coated PCB for protection. Other Tech Edge wideband controllers use pluggable screw terminal connectors but these may admit dust and moisture into the casing, and to keep down the cost, we opted to use flying leads instead.

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 2J1 to your vehicle. Just remember not to short out any of the unused wires against battery voltage or GND.

• 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) .
• Sensor Cable - this is a permanently connected flexible fibreglass sheathed cable brought out via a rubber grommet, with a connector for low cost Bosch LSU 4.2 sensor (UEGO sensor are not supported).
• 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.
• Display Cable - the display cable replicates the standard RJ45 socket found on other Tech Edge wideband units, and provides ground, RS232 communications, and current limited power for a Tech Edge display such as LD02 or LA1.

                   

BLACK	GROUND - Provides a ground return for Vbatt, and a ground reference for NBsim, WBlin-, etc. Also internally connected to the SHIELD wire.
BROWN	USR 1 - A 0-5v Analog channel for logging sensors such as MAP & TPS.
RED	USR 2 - As per USR 2, values appear in the RS232 frame generated by the 2J1 unit.
ORANGE	LSS Tx - An optional Low Speed Serial output (1200 baud), for connection to a future intelligent display, not currently activated in firmware.
YELLOW	Vbatt - Provides battery voltage to remote 12 volt sensors or displays.
GREEN	WBlin- - Ground reference for WBlin+, should be tied to GND or close to GND as it affects WBlin+ if left floating.
BLUE	WBlin+ - 10bit PWM-sourced Differential Wideband output.
VIOLET	NBsim - 10bit PWM-sourced programmable output, used for Narrowband sensor simulation.
PINK	RPM - 12 volt compatible (COIL style) RPM pickup for logging engine revolutions.
WHITE	PULSE - 5 volt PULSE input for logging an additional pulse input, intended for Vehicle Speed Sensors.
