FLASH PROM: A programmable Read Only Memory that can be electrically erased and programmed while remaining in the
circuit. This device is typically used to store the controller’s program.
FUNCTION: A valid command or control sequence executed by the controller.
FUNCTION COMPLETE: Telemetry response generated by the controller following execution of a valid command.
HOOK: This is like the hook switch on a standard telephone. Off-hook means the hand set is off the telephone and on-hook
means the hand set in on the telephone.
INTER-DIGIT TIMER: Sets the maximum allowed time in seconds between valid DTMF digits.
INCREMENT: To increase a value by one or more counts.
INITIALIZE: To set up the minimum data requirement for the system.
KEY CODE: A programmable code that is used with a command code to provide security of the command codes.
LINK: This is when another radio or repeater is used to connect two repeater systems together. Links can be configured as
duplex, half duplex or simplex.
MACROS: Macros allow the repeater owner to define user commands that execute one or more S-Commands thus
customizing the commands for your repeater.
MICROCONTROLLER: A type of microprocessor that contains RAM, ROM, some I/O, etc. into one IC package. This
significantly reduces RFI noise generated by the controller board as all interconnects are very short.
MUTE: Turning off the receiver audio to the transmitter. Mute is usually turned on when DTMF commands are being
received and processed in order that the tones are not applied to the repeater transmitter. This would limit other people at
ground level from decoding your commands and breaking into your repeater.
NSQ: Noise Squelch. A circuit that detects high frequency noise to determine when a signal is present on the receiver input.
The squelch circuit is typically used to gate the voice audio.
PASSWORD: A system access code that is used to secure access to all S-Commands in the RI-1. The repeater owner can
change the password at anytime. DO NOT FORGET YOU’RE PASSWORD or you will have to initialize the controller which
will load default data and you will have to reload all your macros and other information.
PL: Private Line or PL is a Trademark of Motorola for the EIA standard sub-audio tones used for repeater access.
PTT: Push to Talk is the keying of a transmitter. The RI-1 controller generates PTT to your repeater when a proper user is on
the repeater input or when the controller is generating telemetry or carrier delays.
REMOTE BASE: This is a repeater system that has radio attached that is remotely controllable by the repeater user.
SCHEDULER: At specified times of the day when macros are automatically executed.
S-COMMAND: A system command code tells the controller to perform a function or set the controller in a given
configuration.
SECURITY: Security is the limiting of access. Password protection is provided for security.
SQUELCH: This is a circuit that detects high frequency noise to determine when a signal is present on the receiver input.
The squelch circuit is typically used to gate the voice audio.
STATION ID: This is Morse code message of the FCC station license number. This message is sent at a regular interval
during use of the repeater.
SYSTEM COMMAND: Also called S-Command, an instruction that tells the system to perform a function.
