2.3.3 Ignition Sense Cable (KCT-18: Option)
The KCT-18 is an optional cable for enabling the ignition func-
tion. The ignition function lets you turn the transceiver power on
and off with the car ignition key.
2.3.3.1 Installing the KCT-18 (Ignition sense cable) in the
transceiver
(1) The KCT-18 can be installed in the transceiver by the fol-
lowing two methods (Method A, Method B).
Method A: The KCT-18 is soldered to the “IGN” pad on the
TX-RX unit.
Method B: The KCT-18 is connected to the 15-pin connec-
tor of the KCT-60 connected to the transceiver.
„ Installation Procedure: Method A
(1) Remove the two screws on both the right and left sides
of the transceiver, then remove the cabinet and top pack-
ing from the transceiver.
(2) Cut the crimp terminal side of the KCT-18 using a pair of
nippers or similar tool.
(3) Solder the cable side cut in the above step 3 to the “IGN”
pad on the TX-RX unit.
(4) Dress the KCT-18 cable as shown in the figure. The
KCT-18 cable needs to pass through one of two indenta-
tions located on the rear panel of the transceiver.
(5) Cut off the projection of the top packing using a pair of
nippers or similar tool.
If the KCT-18 cable is dressed to be routed through the
indentations on the right side in step 5, the right side of
the projection needs to be cut off. If the KCT-18 cable is
dressed to be routed through the indentations on the left
side, the left side of the projection needs to be cut off.
Following is a figure presenting an example for when the
right side of the projection is cut off.
(6) Reinstall the top packing. Check the correct fitting of the
top packing, then reinstall the cabinet and two screws for
the right and left sides.
(7) Connect the other side of the KCT-18 to the ignition line
of the car.
„ Installation Procedure: Method B
(1) Remove the ACC. cap on the rear of the transceiver.
(2) Connect the D-sub connector of the KCT-60 to the D-sub
15-pin terminal of the transceiver.
(3) Insert the crimp terminal side of the KCT-18 to pin 2 of
the square plug.
(4) Connect the square plug to the 15-pin connector of the
KCT-60.
(5) Connect the other side of the KCT-18 to the ignition line
of the car.
Note:
You must set up using the KPG-175D.
