1 M-400/M-500 Plug and Play Installation Instructions *If you are not familiar with the vehicle’s electrical systems, onboard sensors, and vehicle dynamics, DO NOT attempt to perform ANY installation of PLX Devices Inc. product(s). Please read the instructions completely through at least once before proceeding with the installation to minimize errors. 1) Select a location to mount the M-400/M-500 Plug and Play Controller Choose a location where the device does not obstruct driver’s view and/or ability to safely control the vehicle. Avoid locations exposed to direct sunlight and high temperatures. Never mount the device in the engine bay. Excessive heat will cause failure and damage to the unit. 2) Antenna positioning Due to the nature of wireless transmissions, the position and orientation of the transmitter antenna is EXTREMELY important in guaranteeing that a reliable wireless connection is established. Keep the antenna at least 3 inches away from other metal objects and position it where “line of sight” operation between your Wireless RX Module is maximized. Best performance is achieved when there are no objects in obstruction to the radiated energy between the two antennas. PLX Devices offers a few accessories to maximize data logging performance. • Coax extension cables – Can be used to relocate your transmitter antenna for more positioning options. • High gain receiver antenna – Replaces your reduced height receiver antenna on your RX Module to a 5 inch high gain antenna. This accessory substantially increases receiver sensitivity and operating range. • Wireless to wired conversion cable – Completely illuminates wireless transmission. Signals are sent directly through a coax cable to your RX Module. This offers guaranteed 0% packet loss and optimal data logging performance. 3) Install the wideband oxygen sensor Mount the wideband oxygen sensor before the catalytic converter and at least 24 inches downstream from your engine block or turbo for optimal performance. The sensor element will fail if it is exposed to exhaust gas temperatures above 850 deg Celsius. If you plan to replace your stock narrowband oxygen sensor with the PLX wideband, please read PLXApp004 online for more information. 4) Connect the wire harness to the oxygen sensor You will hear a "click" when the connectors are properly mated. M-400 M-500 5) Connect power to M-400/M-500 Plug and Play Connect the negative wire (black) to your vehicle’s ground. This is usually the negative terminal of your automobile’s battery. Connect the positive wire (red) to your vehicle’s ignition power. This power is only supplied when your key is turned passed a specific position and is off when your key is removed.
2If you plan to integrate the M-400/M-500 Plug and Play with other aftermarket devices by utilizing the analog output signal wires. Make sure that the negative wire (black) is connected as close as possible to your device's ground. This guarantees that both devices "see" the same reference ground and a more accurate interpretation of the output voltages will be achieved. Please refer to the PLXApp notes online for more information. 6) Connect the wire harness to the M-400/M-500 Plug and Play device by mating the two white connectors 7) Install noise filtering capacitors. Ignore this step if you do not intend on using the M-400/M-500 narrowband output and/or wideband output . If you plan to integrate the M-400/M-500 with stand alone engine management systems, piggy back systems, data loggers or any other devices that utilize the two analog outputs (white, gray wires), noise filtering capacitors must be installed near the application. The included capacitors filter out unwanted electrical noise produced from your vehicle’s ignition and other onboard systems. This provides added signal integrity for more accurate, reliable and consistent measurements. 8) Power up the M-400/M-500 Do this before data logging inputs are connected to ensure that your controller is fully functional before proceeding. The unit takes approximately 45 seconds for the oxygen sensor to heat up and produce accurate measurements. If your M-400/M-500 Plug and Play display does not light up immediately, turn off the power immediately and check the power connection wires. 9) Sensor calibration is not needed. The M-400/M-500 is self calibrating and no user intervention is required. When the wideband oxygen sensor is completely heated and exposed to free air, the analog linear wideband output (white wire) voltage should read 5.0V. The M-400/M-500 should display “Air.” 10) Power down the M-400/M-500 11) Determination of compatible signals for data logging The M-400/M-500 accepts two types of signal for data logging. 1. 2 Speed (Measures the frequency of signal pulses) 2. 4 Analog (Measures the voltage of a signal) A compatible speed input is defined as an oscillating pulse which switches between a high voltage and a low voltage. A valid high voltage is 2V-25V with respect to ground (black wire) and a valid low voltage is 0-0.8V with respect to ground (black wire). A compatible analog input is defined as a voltage between 0-5V with respect to ground (black wire). Any voltage between 5-25V will be capped to 5V and above 25V will cause damage to the logger. M-400/M-500 data logger is NOT vehicle specific and was designed to be compatible with most signals to and from you ECU, but not all of them. It is up to the user to determine the viability and compatibility with the intended vehicle to be used based on the descriptions above. 12) Connect input signals for data logger. After you have identified the signals you wish to data log. Connect the appropriate signals to the data log harness.
3Signal Color Speed #1 Black Speed #2 Brown Analog #1 Red Analog #2 White Analog #3 Green Analog #4 Blue 13) Install the USB RX Module device drivers. Insert the USB RX Module into your USB port. Specify the location of your device driver when Windows prompts. Windows will recognize this device as “USB Serial Port (COM3-8)” in your Device Manager->Ports if everything is properly installed. 14) Install the PLXLogger software Run setup.exe to start the PLXLogger installation. After installation is complete, start PLXLogger. Set the USB Port# to match the assigned com port number in step 11. 15) Power up the device M-400/M-500 RX Signal indicator on the upper right should be blinking when your RX Module is within range with the M-400/M-500. The RX LED on your USB RX Module should also be rapidly blinking to indicate that a signal is present.
