One of the interface methods includes rs232.· This image is from the manual (available at http://www.parallaxinc.com/detail.asp?product_id=30058):

The modification that Parallax makes to the LCD display is shown in this.
Errata for LK204-25 (.pdf)
So, with that information, Is there anyway to connect the LK204-25-WB to a PC?

After looking at the errata sheet, you will need an RS-232 level shifter to connect to the PC...MAX232 is a nice inexpensive chip that runs on 5VDC, and can convert to PC RS-232 levels to TTL and visa-versa.
