The problem is if you like to run different software then you are going to have some problems. The manual indicates that you should disconnect the jumper in order to by-pass the battery since it's not needed when running the PCPAKRATT software. That's because the software upon booting loads the parameters on to the PK-232. However if you decide that you would like to use another program, then you'll find that you need the battery in the circuit in order to preserve the parameters in the TNC memory. So the solution is to place a jumper with two leads in the battery circuit and place a mini switch in the back of the PK-232 (there's plenty of room) This will allow you to place the battery in and out of the circuit as necessary. this is nothing new. I wrote a similar message on the BBS's about 3 years ago, but there seems to be some interest on this topic by new owners of the TNC. 73's Kd2ej NYC. ------------------------------------------------------------------------- Note: I haven't tried or verified this, proceed at your own risk.
