SECTION 2 QUICK START
This section will cover the basics of installation and programming of your RI-300. You may also need to review section 4 or 5
for more details on connecting your RI-300 to your repeater. Once you have covered these basics, we recommend that you
thoroughly review the complete manual in order to get the most out of your controller.
UNPACKING THE RI-300
Inspect the carton for the following contents and if any of the items that you have ordered are missing or damaged, notify your
RI-300 dealer or the factory that shipped the unit to you.
1. RI-300 Repeater controller board with mating DB15S connector. RI-310 does not come with the DB15S connector.
2. UM-300 Printed user manual.
3. Optional accessories that may be included with your RI-300.
MOUNTING THE RI-300 REPEATER CONTROLLER
Skip to section 5 if you are installing a RI-310
1. An optional single controller desktop chassis or a standard 19-inch wide 1-3/4 inch high rack mounted enclosure is
available. Mounting holes are provided for the repeater controller boards within the enclosure.
2. The repeater builder can mount the RI-300 repeater controller in any enclosure of his choice. The enclosure that you select
should be strong enough to mechanically protect the contents. The enclosure should be made of metal with good shielding
properties. We do not recommend the use of a plastic enclosure in a RF environment. Mount the RI-300 unit with #4-40
standoffs on the mounting surface.
3. Avoid installing the RI-300 in the following places:
• Directly above a transmitter or power amplifier because of heat and RF considerations.
• Directly above any power supplies because of heat and 60 Hz coupling into the audio circuits.
INTERFACE YOUR RECEIVER and
TRANSMITTER
The RI-300 repeater controller is very easy to interface with
your repeater. Before you continue, you need to make the
following connections. All connections are covered with greater
details in section 4 of this manual. If you are installing the RI-
310, you should go directly to section 5.
