Somebody can help me to identify the JTAG pins in CON2?

See this pictures:

I think that this board don't use a standard JTAG pins sort!

I was looking the PIN map of MV88F5182 (The the excel document embedded with the pins map) but I can't locate the pin for W, 4 and 5.

Here is the board of a PX-NAS1000L. I think it is the same as a PX-WNAS1000L.
U15 is probably a MAX232 or equivalent. As it is not installed, you must convert TTL level to RS-232 level to connect Rx and Tx pin on your serial port.

TTL Rx and Tx
