Each PLX box has a RX and TX port, which use 3.5mm stereo plugs. You need to connect the center pin of the TX port to the s300 to the 'I+' pin on the s300, and the outer shield of the TX port to the 'G' pin on the s300. You can either cut up an old stereo cable, or buy a blank 3.5mm plug and crimp/solder the wires on. If you have multiple PLX devices in a chain, the s300 should be at the end of the chain.

Refer to http://www.hondata.com/help/smanager/in ... meters.htm for the software setup.

thanks for the above information, this was very useful to me.

I have another question regarding this topic:

My wideband is already connected to the digital input and unsuccessful log.

Why would the ecu do "closed loop operation" is necessary to connect the analog output of the box to the pin of the ECU D14??

hello

I make the digital connection from the wideband, to the digital input of the Hondata s300 v2 and this already makes log air / fuel.

but the ECU does not perform the correction of "closed loop"
¿for this to work, I have to connect the analog output of the box "plx" to the D14 pin the ecu?

The digital input cannot run the vehicle in closed loop. It is for datalogging only.

You must use an analog input to one of the ECU pins listed in the closed loop tab.
