Introduction
This chapter describes how the RC-85 repeater controller is remotely
programmed by the repeater owner to customize many of its characteristics.
The controller is programmed with Configuration commands which may be
entered when the controller is unlocked. These commands cause information to
be stored in the controller's non-volatile memory so that the information isn't
lost if power fails. The various types of Configuration commands are described
with examples shown.
Configuration Commands
Configuration commands allow remote Touch-Tone programming of the
controller. They are accessed by placing the controller into a special "unlocked'
mode where only Configuration commands are recognized. Unlocking the
controller requires an "unlock command" unique to the controller, providing
security against tampering. When entry of a series of Configuration commands
is completed, the controller is "locked" up again for normal operation so that it's
secure from unintended changes.
Unlocking and Locking
The controller normally operates in the "locked" mode where Configuration
commands are protected and not accessible. To access the Configuration
commands to make remote changes to the messages, timers, command codes,
etc., the controller must be unlocked.
