State Table
The State Table list box contains all of the possible programmable
commands for a base station. Select the required commands to program
from this list box, the selected command will be displayed in the
Selected Command text box.
Current State
The Current State field displays the control current levels used to
control the DC control base station.
Next State
The Next State field has seven text boxes which can be edited with the
required DC levels for the command displayed in the Selected
Command text box. The DC levels entered for the selected command
must match the base station levels for proper remote control of the base
station.
For example: A conventional base station with two transmit frequencies
and two receive frequencies with Channel Guard enable/disable
capabilities. The station configuration and channel programming might
look something like the following tables.
