Programming and Commands
This section of the manual first discusses some of the things you need to know that are common
to all of the commands. It then has a list of the commands sorted according to their function, a
list sorted according to the command name, and lastly a detailed description of what each
command does and how it is used.
Command Names
The default command names all begin with the letter 'C'. This 'C' is part of the command name,
not just an indication that it is a command. For example, to connect the link to the main port, you
would enter the DTMF tones 'C', '0', '0', '0', '*'. This assumes that your DTMF pad has 16 keys
(0-9, *, #, A-D); the letters corresponding to the numbered keys on a telephone (2=A,B,C) will
not work. The command names can be changed with Command C038.
The <EOF> Key
The <EOF> key refers to the key that is used to tell the controller that the command has been
entered (with the DTMF pad) and that it is time to act on it. It is also used to separate the
command name from any parameters (extra data) it might have. The <EOF> key is '*' by default,
but this can be changed with Command C039.
Programming Messages
Link, and ID messages in the RLC-1 can be changed to a message more specific to your
controller. This is done with command C036, "Message Program Utility." These messages are
composed of CW characters, the codes for which are found in the CW Table (Appendix A). Each
character is identified by a two digit code (leading 0s are necessary for short codes). Each
message has a specific maximum length, although not all messages have the same maximum. See
Commands C036, and C037 for more information on message programming, and C014, C015 and
C016 for CW frequency and speed.
