Pin #2 on the V2 rj12 is Rx, right Joe?
PHP Code:
The grey wire from the UEGO Controller outputs the data stream in an RS232 serial
format. To connect to the pc/laptop, an RS-232 DB-9 connector is recommended. The
grey wire from the UEGO Controller goes to pin 2 of the RS-232 DB-9 connector. Pin 5
of the connector goes to ground. See Figure 5.
AEM says to connect the grey wire to Rx
(pin #2 on DB-9)
There should not be a null modem or any other device in between the V2 and AEM for this tho.
68problemchild, what firmware is installed in the V2?
Have you tried connecting the AEM to a laptop via serial?
