RIBBON-CABLE CONNECTIONS

Connections between circuit boards are accom­
plished with ribbon cables. One end of the ribbon
cables is inserted into the multipin connector while
the other end is soldered to the circuit board. The
ribbon cable to the multipin connector can be
removed or installed by pressing down on the
release bar of the cw h e cto r as shown in Figure 6-1.
To remove the ribbon cable, pull it straight out from
the connector; to install the ribbon cable, insert the
bare wires up to the insulation into the connector.
Remove pressure from the release bare, the ribbon
cable will be lock firmly into the connector.

To provide correct orientation of a cable, a num­
ber " 1 " is stamped on the circuit board and on top
of the multipin connector. The index wire of the rib­
bon is striped a different color than the rest of the
cable. Align the index wire with the pin 1 indicator
when reinserting the ribbon cable into its connector.
Ensure the ribbon cable is evenly trimmed and 5 mm
of wire (about 1/4 inch) is exposed for correct
insertion into the connector.
If any individual wire in the cable is faulty, the
entire ribbon cable should be replaced. When un­
soldering the ribbon cable from the circuit board,
note the location of the ribbon cable for reinstallation
purposes. Align the index wire with the square pad
on the circuit board.
