Howard,
Those pins seem correct.
A good source of info , including the fuse, is at http://www.qsl.net/zl1vk/Maxon9PinSerial.html

Some time back I bought a DM2550NM through this group. I have not used it until today and am having a couple of problems. I suspect I have blown the fuse that is supposedly in the +ve line but I can not locate such a beast.
I am connecting 10.6V + to pin 5, -ve to pin 4 and earthing pin 3 to transmit.
If anyone has any experience with these devices can you please:
1. Confirm the +, - and tx connections
2. Tell me if there really is a fuse
3. And if there is, where it is hidden.
Many thanks
Howard
