The HKN9755A is the stand-alone cloning adapter that is used to clone GP300's and P110's without using RSS and a computer.
This device is microprocessor based and will be very difficult to duplicate.
You can see the schematic here.
Description
The Cloner Adapter model HKN9755A provides a convenient method of cloning the personality of one radio to another.
The personality of a radio consists of programed frequencies, squelch code pairs, scan lists and other operating characteristics stored on the radio codeplug. Unit I.D. codes, model and tuning information can not be changed and will be left undisturbed.
The models and vintage of the radios to be cloned must be the same. The cloner only allows exact copies of like radios to be made.
This adapter can be used with the Radio Service Software as a standard programming cable, but it also has the ability of being used as a cloner. Radio Service Software has the capability of cloning radios, but the cloning adapter gives you the added advantage of portability and speed.
Installation
To install the cloner, first match together the radio and the cloner much like when installing a battery to a radio.
Then slide the two side latches to secure the fit. At this point a battery can be attached to the back of the cloner or the power cable of the cloner can be connected to an external power supply set to 7.5VDC. If a battery is used, then the battery safety latch on the bottom of the cloner should be pulled and turned into place.
NOTE: The cloner has a protective circuit built in, which will cause the fuse to blow when the supply voltage exceeds 10VDC or is incorrectly polarized.
Operation
The cloner has three different user controls, a Read/Program rocker switch, Start button, and the LED's.
When the Read/Program switch is pressed into the Read position, the cloner reads the information of the codeplug from the source radio. With the switch pressed into the Program position the stored data from the cloner is loaded into the target radio.
The Start button is used to begin a Read or Program process.
The LED's are used to indicate the status of the operation, see the table below for a description.
A help label on the side of the cloner can also be used as a reference for operation and LED status.
Cloning
First, connect the source or (master) radio to the cloner and turn radio on.
Toggle the Read/Program switch to Read, then press the Start button and wait for the Busy indicator to stop. The cloner now has stored the codeplug information from the source radio.
Remove the source radio from cloner and connect a target radio to cloner.
Turn radio on, then toggle the Read/Program switch to the Program position and press the Start button. After the cloner has loaded the information into the target radio it may be removed and the next target radio can be connected.
The cloner will store current information as long as a new master radio is not read, even when power is removed from the cloner.
NOTE: Do not operate the cloner if there is a Low battery alert on the radio.
Portability
If the cloner is not to be used as a RSS programming adapter, the cloner can be made, into a completely portable cloning unit.
This is done by removing the programming cable. To remove the cable the cloner must be opened and the cable unscrewed from the cloner.
First, the four housing screws of the cloner need to be removed. The cloner will now open to reveal the cable connections.
Unscrew the connections and remove the cables.
NOTE: For complete removal, one red wire of the programming cable needs to be cut.
CAUTION:To avoid damage to cloner circuits observe the standard servicing precautions used when working with static charge sensitive devices. Wearing a conductive wrist strap (Motorola No. RSX-4015A) will minimize static build-up during servicing.
