RULES FOR LEADING ZEROS IN S-COMMANDS
Leading zeros means that if a command requires a 3 digit value, whether the value is 001 or 100, a total of 3 digits must be
used. All S-Command codes are two digits long. If the first digit of the S-Command is a zero it must always be entered. For
most S-Command data, use the following rule. If the data is a single parameter, then leading zeros are not required for the
data. Example, the controller will see 01 or 1 as the same value if used as the last parameter. All commands requiring
multiple parameters, require leading zeros for each parameter except for the last parameter. Anytime an S-Command
requires two data parameters such as S-Command 40 the first data parameter must have leading zeros and the second data
parameter does not require leading zeros. If you are not sure, always use leading zeros especially when you are not yet
familiar with the controller.

SYSTEM-COMMANDS (S-Commands)
The following sections will detail each of the S-Commands showing syntax, examples, and the default data values. To make
S-Commands easier to locate, the last two digits of each sub-section numbers matches the S-Command number. To execute
an S-Command you must first “unlock” the controller with the current password. When “unlocked” the user commands will
not work. When you are done, “lock” the controller with S-Command 69. You are now in the user command mode.
When you are sending commands via DTMF, the controller is always in one of the two modes (User Command or System
Command) and never in both. When the power is first turned on, the controller is locked and in the user command mode.
When the controller is in this mode, you will hear an ascending 4 tone courtesy each time you un-key with a full quieting
signal. If your signal is not full quieting, the courtesy message will change to a descending 4 tone (weak signal). When you
send the programming password, the RI-200 unlocks and will switch to a programming or System Command (S-Command)
mode. When the controller is in this mode you will hear 2 tone courtesy each time you unkey with a full quieting signal.
Again in this mode, if your signal is not full quieting, the courtesy message will change to a descending 4 tone.
Each time you send commands to the RI-200, you will get one of 3 responses. First, if you send any valid command without
errors, the RI-200 will respond with a CW acknowledgment message “OK”. This message is lower pitch and has the rhythm
of “dah dah dah dah dit dah”. Second, if you send an S-Command with an error or a user command that has an error in its
programming, the RI-200 will respond with a CW error message “ERROR”. This message is high pitch and has the rhythm
of “dit di dah dit di dah dit dah dah dah di dah dit”. Third, if you send invalid command, the RI-200 will not respond
with any message.
When you are programming your RI-200 over the air, it is important to have a full quieting signal to the repeater. As 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:
•
If you key up and send the first digit of the command before the CTCSS or DCS decodes a valid tone, the first digit is
missed and the command becomes invalid or looks like some other valid command.
•
If you move in and out of a RF null while sending a command, a digit may get missed and the command becomes invalid
or looks like some other valid command.
•
If the RI-200 is in the User Command mode while you are trying to send S-Commands and the other way around. Note
that if you are in the S-Command mode after 5 minutes have past without sending a command, the controller will lock
itself. When this happens, you will hear a CW “OK” without sending a command.

NO OPERATION
This is a null command and does not perform an internal function. Primarily, a NOP is used to write over data in a macro
that is no longer desired.
