Tech edge wb use with v2 bbl

[AGRO]

with the tech edge, it already has a rj11 and rj45 plug/s. which one to use? pin 1,2,4 on the rj11 or pin 2,3,5 on the rj45? im a little confused.





Other RJ45 Outputs - SVout, NBsim, WBlin+, GND & Vbatt

The SVout [pin 1], WBlin+ [pin 4] & NBsim [pin 6] signals are all described in detail above. The SVout signal is intended for analogue displays like the LD01 and those displays will also use Vbatt & GND described below. The RJ45 connector signal names are shown at right.
A fused, protected and partially filtered battery voltage Vbatt is available from [pin 8] (right most RJ45 signal). This output is provided to power other devices such as the LD02 display. It should only be connected to devices that will draw small currents; typically less than 100 milliamps. Excessive current consumption may cause heating of an internal dropping/protection resistor.
A ground GND point [pin 5-RJ45] is provided as a return for the RS232 and Vbatt connections.
Note that there are number of unconnected outputs (N/C = No Connection) on each of the RJ-45 connectors. Those N/C's that have uses on other wideband units are shown "greyed in" and include WBlin (pin 4) and NBsim (pin 6).
6 Pin RJ11 Connector - LSS Tx & Rx, also SVout, WBlin+, GND & Vbatt

The right hand side RJ11 connector is designed for use with an intelligent serial display. Its primary feature is a second serial channel called the Low Speed Serial (LSS) interface which has a 1200 baud data rate (ie. low speed) which is adequate for most displays. Additionally there are duplicates signals found on the RJ45 and green 6 pin connector.
LSS Tx [pin 2] sends data frames to display. LSS Rx [pin 1] is not currently supported in firmware.

Batt+ [pin 6] & GND [pin 4] provide current limited power and a return GND for the external display.

SVout [pin 5] & WBlin+ [pin 3] are described in sections above.

I would use the serial data pins from the RJ45 connector, but it would be wise to check with TechEdge first.

 TechEdge <-> FlashScan
     RJ45 <-> RJ12
GND Pin 5 <-> Pin 5 GND
 TX Pin 3 <-> Pin 2 RX
 RX Pin 2 <-> Pin 1 TX

I think that's right, I may have mixed up the TX/RX but you get the idea.

Has any one got there Mainline Dyno out putting serial data to the v2 cable , my V2 led flashes but the data does not match up using 1.5 or 2 techedge in the V2 i'm just pluging in to the rs232 plug on the case of the weather / wideband controler as per where you plug in to do a wb cal

Attached is a log from the serial monitor program

and a link the the wideband used in the mainline dyno

http://wbo2.com/2d1/default.htm

some help would be appreciated

What do you see in FlashScan's Wide band display?
do you see "no controller detected" or do you see incorrect Lambda/AFR values?

P.S. The data stream looks like TE 1.5 version.

it finds tech edge 1.5 just the data is not right

it finds tech edge 1.5 just the data is not right

I'll go over the conversion code again, I may have messed up the conversion from A/D counts to Lambda.

Could my problem be that the data is techedge V2.1

[Blacky]

If you select techedge V2, does it show "Controller not found" or junk data?
I did have an error in the V2 AFR calculation it will be fixed in the next update.
The V1.5 should be ok, but I will be re-checking it again.
Peter from TechEdge is kindly helping out.

I was able to see the TechEdge 2J1 unit in the current BBL version, and again had the flashing LED indicating serial data. The indicated AFR's were on the lean side though, around the 100:1 mark making logging not very good for tuning. The great thing about the TechEdge is that the analogue O/P is "earth referenced" to the testing device. So I've tied the TechEdge analogue -ve lead to an earth on the V2 to remove the earth offset problem. I simply used the earth point on one of the switch I/Ps on the V2. This removed the 0.03v earth offset and should allow me to log accurately until the serial conversion is worked out. If anyone is interested, I'll post a pic of the setup.

Simon.

Simon, yes please post a pic if possible.
Thanks,
