3.3.5 Begin Assembling your Radio Cable
Assemble the tools, PK-900 Radio cable and connectors you will need
for each radio you wish to connect. You will probably also need a
small soldering iron (20-40 watts) and solder at your work area.
3.3.5.1 Prepare the Radio Cable
1. Locate one of the 5 ft PK-900 radio cables included with your
PK-900. Note that the Radio cables may have been shipped as a
single 10 ft cable which should be cut in half before use.
2. Prepare the bare end of one of the radio cables by removing an
appropriate amount of the jacket for the connector you will be
attaching. Usually this is 1/2 to 3/4 inch.
3. Carefully remove the foil shield exposing the colored wires
underneath. Be careful not to nick or cut the bare shield wire.
4. Strip back 1/8 inch of colored insulation from the GREEN, RED,
WHITE and BROWN wires.
NOTE: The BLACK wire is the squelch input and normally not used.
The black wire is only needed for Packet operation if the
channel you plan to operate on is used for both voice and
data. If you need this connection, strip away 1/8 inch of
BLACK insulation as done with the other four wires. If
this wire is not needed, then leave the insulation intact.
3.3.5.2 Verify the Connection Points with Your Manual
Look at the connector closely (with a magnifying glass if necessary)
and locate pin 1. Compare this to the location of pin 1 on the
connector drawing in your transceiver's manual and also in APPENDIX E.
This is important as some diagrams show the connector from the inside
of the transceiver, not the outside of the plug you are wiring. This
will help insure that the plug is not wired backwards.
3.3.5.3 Prepare the Connector
Now that the cable is prepared, you are ready to prepare the connector
for wiring. If the connector you are wiring has a shell, be sure that
it is placed over the cable before any connections are made. If this
is not done, an otherwise perfect wiring may have to be redone.
3.3.5.4 Wire the Connector
The following connections must be made for transmit and receive
operation of the PK-900. Refer to table 3-1 and figure 3-2 as well
as APPENDIX E and your transceiver's manual when making these
connections.
HINT: When wiring a Connector, it is often easier to wire the
inside or middle connections first and work your way to the
outside pins. For this reason the following steps are not
numbered and may be done in any convenient order.
