SECTION 1 INTRODUCTION What is the RI-300(e) Version
The RI-300e and RI-310e are revised versions of the RI-300 and RI-310. The RI-300e has some enhanced performance
features, including a battery backed real time clock (RTC). This manual will cover both controllers. Areas where there are
differences between the controllers will be clearly pointed out. However, when this manual talks about the controller as
“RI-300” or “RI-310” it is also including the “e” version.
Overview
Your controller represents the latest technological advances in repeater control systems. The RI-300 utilizes a microprocessor
design, which provides all the control functions for a single repeater on two printed circuit boards, each 3½ by 6 inches. One
board provides all audio processing and the second board provides for digital processing. With this two-board design, the
digital data is isolated from the audio to produce superior audio quality. The RI-300 does not require memory backup batteries;
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-300 is easy to set up and use. Only five interconnect wires are required to interface to your repeater. With three simple
audio level adjustments, your repeater will be operational with the default user commands. The telephone is connected with the
provided RJ-11 telephone jack.
Once you are familiar with the macro command system, you can customize your user commands, messages, and schedulers.
We recommend that you read sections 1 through 3, 8 and 9 of this manual first, to get familiar with the system and its basic
operation. The other sections of this manual provide a more thorough explanatio n o f the RI-300's many features.
Feature List
The following features of the RI-300 repeater interconnect are not available together in any other repeater controller in the
industry:
• On board CTCSS and DCS decoder and encoder. You do not have to add an external decoder. The decoder and encoder
are remotely programmable. Multiple CTCSS and DCS tone panel features are provided.
• Full duplex telephone interface with a self-balancing hybrid.
• Speech synthesizer. Read back system configuration and create your own speech messages. Includes a 661-word
vocabulary and 32 command words (example Time, Temperature, etc.).
• Optional digital voice recorder. Create your own messages or station identification in your own voice.
• Flash program memory. You can make firmware updates without changing any components.
• Local microphone and speaker connections.
• Auxiliary audio buss. Connect as many as 8 controllers for links, remotes and multiple repeater connections.
• The Transmit audio level, squelch level, tone generator level, CTCSS level, DCS level and telephone level potentiometer
adjustments may be remotely adjusted by radio.
• On board squelch circuit. You do not have to add someone else’s circuit. This is SmartSquelch, an intelligent
microprocessor-controlled squelch already installed on board, and it’s fast.
• A selectable sub audio reject filter is provided to remove the received CTCSS sub-audio tone from being repeated.
• DTMF tones may be passed, muted, or regenerated.
• Dual tone generator with level and frequency control is available.
• In-band frequency counter.
• Temperature sensor input
• Analog input for S-Meter or other analog devices.
• User programmable inputs and outputs.
• User programmable event scheduler. Commands can be programmed to execute automatically at user-selected times.
• Built-in receiver audio level meter. You do not need a voltmeter or scope to set up the receiver audio level.
• NON-VOLATILE EEPROM data storage. You never have to be concerned with replacement of the memory backup
battery.
• User command macro editor. All user commands are completely programmable.
• All the repeater owner has to do is interface the repeater audio and remotely program the functions and features desired.
