The pin N o. indications (1 and 50) near the C N 2305 connector and the pin
numbers adjacent to the signal names are printed in reverse on the board.
On the board, the leftmost pin is labeled Pin
N o.
1
and the rightmost Pin N o.
O
.
However, the actual pin numbering is Pin N o.
1
at rightmost and Pin N o.
O
at
leftmost.
N ote that only the printing of the pin numbers is wrong but that that of the signal
names is correct. When performing diagnosis, be sure to interpret the pin numbers
of the connector in reverse (enumerated right to left).
