SECTION 8 INITIAL SETTINGS
This section will cover some items that you will need to modify before you put your repeater on the air. But first, confirm the
following items to make sure that your controller is operational.
1. Turn on the power to the repeater.
2. Apply a carrier without a CTCSS tone on the input of the repeater. The NSQ LED should come on.
3. Apply a carrier with a DTMF tone on the input of the repeater. The DTMF LED should come on.
User and System Command Modes
The controller is always in one of two modes: (User Command mode or System Command mode) but never in both.
Commands sent via DTMF will be interpreted depending upon the controller mode at the time that the command is received.
When the power is first turned on, the controller is locked, and is in the User Command mode. After receiving the
programming password in the User command mode, the RI-1 unlocks and will switch to the programming (System Command)
mode. If no commands are send for an extended period of time, the controller will lock it self. After you have finished sending
System Commands, you can lock and save your changes or lock and discard your changes.
Command acknowledgment
Each time you send commands to the RI-1, you will get one of two responses. First, if you send any valid command without
errors, the RI-1 will respond with a CW acknowledgment message “OK”, or a function complete message of your design. The
“OK” message is of low pitch and has the rhythm of “dah dah dah dah di dah”. Second, if you send an S-Command with an
error or a user command that has an error in it’s programming, the RI-1 will respond with a speech message: “ERROR.
When you are programming your RI-1 over the air, it is important to have a full quieting signal at the repeater. With a noisy
signal, digits can be missed and the result of the command may not turn out the way you planned. The following is a list of
some common problems people have encountered:
• If you move in and out of a RF null while sending a command such as when using a hand held, a digit may get missed. The
received command then becomes invalid or worse yet, looks like some other valid command.
• If the RI-1 is in the User Command mode while you are trying to send S-Commands, or the controller is in the S-Command
mode while you are sending User Commands, you will not get the results you are expecting. Note that if 5 minutes have
past without sending a command while you are in the S-Command mode, the controller will lock itself. If the time-out
should happen, you will hear an unexpected CW “OK”, or a function complete of your design, automatically sent by the
controller.
