[Motorola] public safety using DCS

Thu, 1 Aug 2002 00:59:09 -0400

Yes they will support as many keys as you want, but the cost gets
higher for better boards. Some radios have a internal socket already
set up for these type of boards. The ones that do not, you must solder
 a few wires.

Programming the boards can be done by computer and some support over the
air programming.

Okay, well I take it then that the DE boards won't support as many keys
that are out now, and these boards will go into the radios, but what about
the keyloader itself?  Do i just plug it int one of the two jacks in the
top of the radio?
