Hello,

please excuse my bad english.

I have a one for all 7962. Now I have a receiver and a Amp which needed new codes.
Which cable I need.
I read many about that the 7962 is JP2. Can I use a JP1.3 Cable?

Thank you for the help.

JP1.3 cables which are based on the FTDI chipset will work. Ones which are based on the Prolific chipset (DIYGadget, Tiao) don't work.

Ok, thank you for the info.
Where can I buy it?
Is there a tutorial to do build it by myself?

Ok, I find this in Germany

This is the same or not?

Now I need the 3x6 adapter. Is there any shop in germany?

The Software RemoteMaster.v2.03Alpha22 is right?

Looks good to me. But if you buy from the Chinese vendor with worldwide shipping, you won't need a 3x6 adapter. Just glue the pins together.

In the US, Mouser is one vendor that sells the connectors. I don't know about Europe.

Ok, it is the same as that from Germany I think.

The Software RemoteMaster.v2.03Alpha22 is right to load new keys in the OFA?

Yes, that version should work.

Pins usually go:
5 6
3 4
1 2

with 1 marked as Vicky said. Rotate the above to match your remote. Once you get it right, superglue them together and mark pin 1 somehow.

Use the following pin numbers on the JP2 6 pin connector. I suggest you ignore the colors or numbers of the wires in the cable. Make the connections based on the functions printed on the circuit board.

JP2 Cable
pin 2 RTS
pin 3 Ground
pin 4 TX
pin 6 RX

pin 1 Power
We ordinarily don't connect power to the remote, but there is no harm in connecting 3.3 volts. If your cable is a 5 volt version, I recommend against connecting power to the remote.

Do not connect anything to pin 5.

OK, the 7962 is JP2?

I cant't see the numbers because the case is over it.
And don't want destroy the case.

The 7962 uses the MAXQ612 processor. This is a JP2 class remote, although most JP2 remotes use the MAXQ610 processor. The 612 has more memory. The communications protocol is JP2.
