Section 4. Programming
4-3
The following commands are used to configure the operation and privileges of individual
users on the repeater. Where the variable “uu” appears, it represents the user number
associated with a particular receive CTCSS tone or DPL code. This can be a two or three
digit entry, no leading zero is required for numbers under 100. A listing of the relationship
between user numbers and tones or codes can be found in Tables 3-1 and 3-2. The user
number "999" may be used with most of the following commands to globally program all
users at once.
Enable and Disable a User
In order to enable service to a particular tone or code in the Model 37-MAX, the user number
associated with that tone or code must be enabled. The two commands shown here are used
with the appropriate user number to start or suspend service. By default, all users are disabled
and must be individually enabled to provide service. The user number "999" may
not be used
to globally enable or disable users. The user number "00" is used to turn on and off Carrier
Squelch repeater operation.
110# uu# Disable User Number “uu” (default)
111# uu# Enable User Number “uu”
Tone Translation
In the Model 37-MAX, there is a fixed relationship between any given user number and the
tone or code that will be decoded when that user is enabled. By default, a user will encode the
same tone or code that it decodes, but this is not a fixed relationship. The encode output of
any user can be programmed for another tone or code using the command shown here. The
command requires that the user affected be specified first (uu), followed by the user number
of the new tone or code to be encoded (ee). Setting the variable “ee” to zero will produce a
Carrier Squelch output, 1 to 50 for a CTCSS tone, and 51 to 154 to chose a DCS code.
122# uu# ee# Tone Translation (default, encode is the same as decode)
Tone-In-Tail
In many repeater systems, the controller drops the encode of the CTCSS tone or DCS code
when the radio user that was transmitting unkeys. This provides a convenient way for persons
and equipment monitoring the repeater transmitter to know when the mobile has unkeyed,
even though the repeater transmitter is still keyed. There are other types of system
configurations though, that require the encode to continue for the entire transmitter hold time
(commonly referred to as the repeater “tail”) for proper operation. The two commands shown
here are used to configure the 37-MAX for whichever mode of operation fits the system it is
installed in. The default setting of this parameter is for no encode during the transmit hold
time.
120# uu# Encode Disabled During TX-Hold for User “uu” (default)
121# uu# Encode Enabled During TX-Hold for User “uu”
