Hi there.
I have allmost build the RLN4008B But i have some questions before i turn it on.
I asume that the power in is from 10-30 volts, the first it hits is the regulator...?
What does the battery do? is it just so the rib dont need power from the outside? or does it have some backup memmory?
i cant fint a swich with 5 poles to the pcb here in Denmark, but in the diagram the swich is only 2 pole?? what holes in the pcb do the swich sit in then? that is if i gonna use a normal 2 pole swich. it is only power on/off right?
Also. i can´s find cables that fit the 15 pole jack...? on all other rs232 it is 9 pole..
Kind regards Jens

Power in = 12VDC nominal (10-16)

Battery is for field operation away from power outlets. There is no memory in the RIB.

I believe the switch is a DPDT, but I'll have to see the schematic to verify. It only switches power.

You have to fabricate the DB9 to DB15 PC serial cable. The cable is described at Batlabs.

Look here, the up-dated RIB schematic. http://www.batlabs.com/images/rib_mod.jpg
This uses a standard RS232 25 pin connector for the computer side. You can use the standard 9 pin RS232 connector.

There have been many more up dates since that one.

If you build your own radio interface cables, you can make sure that there is a feed from the switched B+ line on the radio accessory connector to the RIB. This then powers the RIB from the radio and doesn't rely on the 9 volt battery or an external wall wart.
