Sigtronics Y-ADP-IC3 Adapter Installation Instructions
Description
The Sigtronics Y-ADP-IC3 “Y” adapter is designed to simplify the process of
connecting a Sigtronics intercom or MRIM-2 system to ICOM radios. See
the Sigtronics web site for specific models.
Installation
1. To select an appropriate mounting location for the adapter, first connect
it up to the radio. To do this, unscrew and remove the two screws on the
top of the Y-ADP-IC3 adapter. Leave the lid in place on the adapter for
now.
2. Unplug the hand mic from the radio, you may also have to unhook the
cable strain relief, and plug it into jack on the Y-ADP-IC3 adapter module.
3. Plug the cord connector of the Sigtronics Y-ADP-IC3 adapter into the
hand mic connector on radio.
4. Now you are ready to select a mounting location for the adapter. Select
a spot out of the way so that the adapter and its cables will not interfere
with the normal operation of the vehicle. Note: One more cable will have
to come out of the adapter for the wires that go to Sigtronics intercom or
MRIM-2 unit. This cable can come out of any side of the adapter except
the top. For convenience, the bottom of the adapter already has a hole
for this. Make sure that the hand mic has enough cable length to be
used properly.
5. Hold the adapter on the intended mounting place, remove the adapter
lid, and carefully slide the PCB out of its slot. Mark with a pen or pencil through the two mounting holes and the cable hole (if desired) on
the bottom of the adapter. Note: As an option to using the sheet metal
screws, the included double sided foam tape may be used to mount the
adapter. If the cable to the Sigtronics intercom or MRIM-2 unit needs to
come out the side of the adapter mark that hole also. Note: Cable holes
on the side of the adapter should be as close to the bottom as possible
to clear the adapter lid. Drill all the holes and mount with the supplied
#10 sheet metal screws.
6. Route the cable from the intercom or MRIM-2 unit through the hole on
the adapter. Note: Use the wire supplied with the Sigtronics system for
connection to the Y-ADP-IC3 adapter terminal block. If unavailable use
wire that has 22 or 24 gauge stranded conductors. Cut to length but leave
a few inches for access.
7. Strip the insulation from the individual conductors about 1/2 inch. Twist
the conductors to eliminate any loose strands and insert the wires into
the terminal block holes. See drawing on back for color code. To insert
the wire, use a finger nail or small screw driver, press and hold the selected orange tab towards the circuit board and insert the wire into the
matching hole. Make sure the wire is inserted enough into the hole that
insulation touches the hole entry (no exposed bare wire). Release the tab.
Carefully inspect and fix any loose wire strands that did not make it into
the hole. Repeat for all wires. Reinstall the PCB in the slot.
8. Install the provided tie wrap securely on the intercom or MRIM-2 cable
so that the wires won’t pull out of the adapter box.
9. Replace the adapter box lid making sure the wires do not get pinched
around the edges. Reinstall the lid screws. Put the hand mic cable strain
relief hook into the eyelet on the corner of the adapter if applicable.
NOTES: Hook up the speaker wires (2 violet wires) from the Sigtronics
intercom or MRIM-2 unit to the radio speaker leads. The back of the ICOM
unit has a 3.5mm 3 conductor speaker jack. Connect one Violet wire to
the Tip (Speaker Hi) and the other Violet wire to the Barrel (Speaker Low).
No connection at the Ring. Adjust the Sigtronics intercom or MRIM-2 units
transmit and receive levels per their appropriate installation instructions.
Your existing radio hand mic and speaker will still function as normal.
WARRANTY: One year parts and labor.
