Attn Electrical guys: Nissan CONSULT port to serial port

Was wondering if anyone knew of a conversion cable to read data
from the Nissan CONSULT port (under the dash near hood release) and
transmit the data to an RS-232 serial port?

The best i could find was the Conzult product which is kinda expensive,
and the software is limited.

The port:

The electrical schematic for converting Consult to RS-232:

If I had the cable I think I could write a program to monitor activity.

Damn it, no one knows?

Buy and EMS and plug your serial port into that…
