TELEMETRY MESSAGES
Telemetry or messages are sent from the controller to you in response to a repeater status or function. There are primarily
three types of messages. 1) The station ID. 2) Courtesy messages, which occur after you un-key. 3) System functions (OK,
ERROR and system status). Any of the messages may be modified with S-Command 31. The controller comes pre-
programmed with default messages in response to any one of the following events:
EVENT
DESCRIPTION
Clock Set Courtesy
Courtesy message is sent after each user unkeys to let other users know when the time-out timer
has been reset and it is OK to continue talking. This message occurs when the time clock has been
set.
Weak Signal Courtesy
Replaces the courtesy message when the received signal is weak or noisy.
Clock not Set Courtesy
Replaces the courtesy message after power has been restored to the controller. This message is
used when the time clock has not been set.
Un-lock Courtesy
Replaces the courtesy message when the controller is unlocked or in S-Command mode.
Post time-out
Generated when the time-out offender releases his PTT to inform the user of this condition.
Pre time-out
Generated just before the controller chops off the transmission of the user that timed out.
ID
This is the system identification, usually in CW. The factory default is “HELLO”. This ID is sent
periodically as required by the FCC.
Function Error
Generated in response to an S-Command that the controller did not understand.
Function Complete
Generated in response to an S-Command the controller understood and executed.
Ring
Generated in response to someone calling on the telephone.
AP Answer
Message sent to someone calling on the phone when the controller is waiting for a password.
AP Function Complete
Generated on the telephone in response to an S-Command the controller understood and executed.
AP Error
Generated on the telephone in response to an S-Command the controller did not understand.
AP Ring Back
Generated on the telephone to identify that ringing is in process on the repeater.
It should be noted that when the controller is executing a macro, the function complete or function error is in response to the
S-Commands within the macro. If you get a function error when controlling your system with a user command, you have an
S-Command with an error within the macro.

SETTING AUDIO LEVELS
The RI-210 is shipped with audio levels already set for the Vertex repeater, however final adjustments may be required. If
you are installing a RI-200 or checking the RI-210 audio levels, use the following procedure.
Warning: Refer to section 3.8, Initialization procedure. When a full controller initialization is performed all digital pot
settings are returned to their default settings. Do not perform the initialization procedure at this time. During full
controller initialization, all system settings, user commands, macros, messages, and digital pot settings will be returned to
their defaults. While holding down the initialization button, apply 12 VDC power. After all the LED’s are turned on, you
can release the initialization button and only the system data will be modified. If you continue holding the initialization
button for more than fifteen seconds, the digital pots will be reset.
Note:
If you are having startup problems, check the following items.
1.
When entering your password for the first time, make sure the COS, CTCSS and DTMF status LED’s are operating
properly. Most of the startup problems will relate to discriminator audio level too low, too high, too much DTMF twist
and/or audio distortion (or CTCSS level too high or low). If your discriminator does not have adequate filtering of the
455 kHz (second IF frequency), you will have to provide for this filtering between the radio and controller. The RI-200
design has a wide dynamic range for all of the decoders and should work in most conditions.
2.
The un-key of your radio when sending a command is a normal command termination. If you are experiencing a
problem when getting started or the COS is always on, you can use the “C” DTMF character for the command
termination. This should only be necessary until you get the receiver and squelch properly set.
