AEM UEGO setup

[Matt]

There are about 15 topics on this wideband in this area so I'll combine things together in this thread

There are two ways to get UEGO data into Nistune
1. Serial connection.

Purchase a FTDI based USB-serial converter, and DB-9 connector

Connection info here:
download/file.php?id=268

Other brand may not work properly. See:
viewtopic.php?f=33&t=3155
viewtopic.php?f=33&t=2775

BLUE - pin 2 of DB9 connector
BLACK - pin 5 of DB9 connector

Solder the connector to the UEGO and check firstly using terminal program

or try teraterm

1. After install click Serial and select COM port
2. Default settings 9600 / 8 bits / no parity are already set so you should receive data straight away



After this works, close the terminal program, select AEM UEGO, same COM port, connect inside Nistune (see Software Users Manual - Wideband section)

2. DLP A/D converter. Ground all unused inputs, except Channel 1. Otherwise you get noise

Then connect 5Voutput to Channel 1, and sensor GND to DLP ground

Fail safe requires the com0com emulator. More notes here:

Part 2 testing inside Nistune 1.3.2

[Shane001]

Matt I have this setup with an FTDI based USB-serial converter and in hyperterminal all is OK.

However when I connect to this wideband in Nistune, it shows the value at the point of connection and then freezes. If you continually disconnect and reconnect some times it will connect and not freeze, but sometimes this can take 5-10mins of connecting/disconnecting to get a continual signal in Nistune.

Do any of the com port values need to be changed from defaults in Device Manager?
Seems to be a problem with the signal possibly overloading in Nistune?

Seems to be the exact same problem reported in this post.

Hi Shane

Please make a debug log (wideband only, no consult connected) and post/email it to me

File > Config > Misc > Debug logging

This will record all the wideband data going into the software and the disconnects. I can then review and see what is going on.
