*Each of these devices uses this connection.
**Pinout shown is for use without Plug In Adapter (8804 P/N 127358 00A, 8860 P/N 128019 00A).
***The 8855 using RS-232 must have the 129618 00A Interface PCB. The baud rate for the JAGXTREME terminal must be set to 300 baud. If
the interface PCB is part number 123654 00A or 137651 00A, the JAGXTREME terminal TXDA terminal must be connected to Pin 2 of the
8855 Interface PCB. In this case, set the JAGXTREME terminal baud rate to 1200.
