INTRODUCTION
What is the RI-1
The RI-1 is a standalone repeater controller that can be connected to an auxiliary buss to communicate with other RI-xxx
controllers. Other then the difference in mechanical form, the functions and features of the RI-1 and PE-1 are the same. This
manual will cover both controllers. Areas where there are differences between the controllers will be clearly pointed out.
What is the PE-1
The PE-1 is a standalone repeater controller that is installed inside the RI-300 controller chassis. It can communicate with the
RI-300 controller over the auxiliary buss. Other than the difference in mechanical form, the functions and features of the PE-1
and RI-1 are the same. This manual will cover both controllers. Areas where there are differences between the controllers will
be clearly pointed out.
Overview
Your controller represents the latest technological advances in repeater control systems. The RI-1 utilizes a microprocessor
design, which provides all the control functions for a single repeater or link on a single printed circuit board. All program
configurations are stored in a NON-VOLATILE EEPROM (Electrically Erasable Programmable Read Only Memory), which
maintains its data even with the power disconnected. This EEPROM may be re-programmed by the user in order to change the
system characteristics. A “WATCHDOG TIMER” and “POWER SUPPLY SUPERVISORY CIRCUIT” constantly monitor
the microprocessor and power supply, maintaining the operational integrity of the system. The RI-1/PE-1 is easy to set up and
use.
Once you are familiar with the macro command system, you can customize your user commands and messages. We
recommend that you read sections 1 through 3, 7 and 8 of this manual first, to get familiar with the system and its basic
operation. The other sections of this manual provide a more thorough explanation of the RI-1/PE-1's many features.
Feature List
The following are features of the RI-1 and PE-1 controller:
• Flash program memory. You can make firmware updates without changing any components.
• Auxiliary audio buss. Connect to other controllers for links, remotes and multiple repeater connections.
• The receiver audio level, auxiliary audio level and tone generator level may be remotely adjusted by radio.
• A selectable low pass audio filter is provided to remove adjacent channel splatter.
• DTMF tones may be passed, muted, or regenerated.
• A dual tone generator provides both level and frequency control.
• User programmable inputs and outputs exist for external sensing and control.
• NON-VOLATILE EEPROM data storage. You never have to be concerned with replacement of the memory backup
battery.
• User command and macro editor. All user commands are completely programmable.
The RI-1 provides excellent audio quality. With proper consideration when interfacing the controller to the receiver and
transmitter, your repeater will provide excellent audio to the users. Interfacing information is provided in numerous sections of
this manual and support is available from the factory. The RI-1 provides for easy programming of customized user features or
user commands by giving you the ability to write and name simple macros. All messages and telemetry are also programmable.
