6-PIN AND 20-PIN SOCKETS
Refer to Pictorial 1-7 for the following steps.
NOTE: Perform the following steps carefully. The
sockets are very difficult to remove once they are
installed wrong.
(
)
Use the following procedure to install one of the
20-pin sockets on the circuit board:
1.
Push the socket onto the edge of the circuit
board next to the data jumpers.
2.
Make sure the circuit board is between the
two lugs at each socket connector. Also
make sure each lug lines up with a foil on
the circuit board. NOTE: The lugs at one end
of the socket must line up with foil contact
"0" on the circuit board as shown.
3.
Solder only lugs 0 and 19 to the foil on the
component side of the circuit board. The
other pins will be soldered later.
(
)
Locate a 6-pin socket. Then refer to Detail 1-7A
and cut off the indicated lugs at one end of the
socket.
( )
Push the prepared 6-pin socket onto the edge of
the circuit board next to the 20-pin socket. Make
sure the circuit board is between the two lugs at
each socket connector. Also make sure each lug
lines up with a foil on the circuit board. NOTE:
The socket hole where you cut off the lugs must
be between foil contacts 24 and 25 as shown. Do
not solder any of the lugs yet.
(
)
Push the remaining 6-pin socket onto the edge
of the circuit board next to the other 6-pin soc
ket. Make sure the circuit board is between the
two lugs at each socket connector. Also make
sure each lug lines up with a foil on the circuit
board (foil contacts 25 through 30).
