Wiring Diagram TE-5301 Wideband Display for a Car

RealAutoTips. - Here is Wiring Diagram TE-5301 Wideband Display for a Car. The 5301 display is based on the Silicon Chip FMD described here. We modified the sensor input circuitry to provide an 8 bit resolution A/D converter between the 1.4 and 3.1 volts limits produced by the DIY-WB. We also added the RS232 option for data logging to a Palm or PC. The wiring diagram of this device like in figure 1 below.

Description

Wiring diagram like in figure 1 is Wiring Diagram TE-5301 Wideband Display for a Car. This is the construction guide for the 5301 wideband fuel mixture display kit. The 5301 is the Tech Edge version (rather than the Jaycar version) of the modified Silicon Chip FMD design, and it features, compared to the original kit, double sided PCBs a new front panel design, in-built RS232 output and superbright GaAlAs 7 segment LEDs The 5301 uses the same version 1.1 software as the 5300 and, unless noted otherwise, is known elsewhere on this web site as the 5300 unit or the modified FMD display.
