Pre Command Prefix
Sometimes it may desirable to be able to access commands that haven’t been remapped using a Command Macro without having to
first unlock a Port. By defining a Pre Command Prefix (up to 4 digits is permissible), you can access those commands that normally
require unlocking a Port with the exception of programming commands that start with a star ( *). Any command shown in Appendix C is
acces
sible in this manner. You may also disable this feature if it’s not needed by programming a zero:
*2109x
where x is from 1 to 4 digits for use as. If programmed to 0, no Prefix is used and this feature is disabled.
If disabled you must first unlock a Port in order to access commands.
Pre Access Code
You may program a
Pre Access Code
which will then be required to be prepended to all commands EXCEPT UNLOCK CODES AND
COMMANDS ENTERED WHILE THE RC210 IS LOCKED. In other words, you will need to use any programmed
Pre Access Code
before any Command Macro. This is not to be confused with the Pre Command Prefix above.
Probably the most common use of a
Pre Access Code
is as a
Site Prefix
in a multi-controller, linked system. By using such a prefix, all
controllers in the system can use identical codes with
the Pre Access Code
serving as a site address. For example, let’s say we have a
linked system consisting of 3 repeaters, all linked together full-
time. At each site, we use the command of “ABC” to read backup battery
voltage. So we assign site #1 a Pre Access Code of “1”, site #2 to “2” and site #3 to “3”. Now we access site #3 from site #1 and send
DTMF digits
3 A B C.
Site #3 will now read back its backup battery voltage down the link back to site #1. Similarly, we can use
addresses in this manner for and from anywhere within our system.
*2108x
where x is 1 to 3 digits. If programmed to 0, no Pre Access Code is used.
Locking (Leaving Program Mode)
To lock the controller when you're done programming, you use a (by default) single "#". The controller will respond with "LOCK",
confirming you are no longer in program mode. Also, when any port is unlocked, a timer is started. Should no valid DTMF digit be
received at least every 2 minutes, the controller will automatically lock itself and announce that fact.
Programming A Custom Lock Code
Perhaps # conflicts with your intended code scheme, so the RC210 allows you to reprogram the Lock Code to be up to 4 digits long.
This code is not unique to any port and will be used to lock the controller regardless of which port is unlocked at the time.
*9010xxxx
where "xxxx" is your new Lock Code of any length from 1 to 4 digits.
Programming A Custom Terminator Digit
By default, the RC210 recognizes a "D" as its terminator digit, forcing any DTMF digits beforehand to be evaluated by the command
decoder. Under some circumstances, "D" may conflict with a code used for some other function. If necessary, you can reprogram the
terminator digit to be any other single DTMF digit.
*9020x
where "x" is the single DTMF digit that will cause the RC210 to evaluate DTMF digits preceding it.
A Word Of Caution Regarding The Terminator Digit
Should you decide to change the Terminator Digit from its default value, remember that you can no longer use that new digit anywhere
in any command. For example, it would be a bad idea to use "1" as your Terminator Digit, as you would not be able to use "1" in any
other command, as well as losing access to the defaults commands that have a "1" in th
eir code. Nor would “ * “ be a good idea, as
you’d never again have access to those programming commands that start with an asterisk (which is just about all of them!).
Generally speaking, if you wish to redefine the Terminator Digit, you should strive to use one of the less commonly used DTMF digits,
such as A, B,C or D. But you must also make certain that whichever digit you decide to use does not conflict with a default command
either. For example, A is used as part of the default Remote Base Prefix Code. If you wish to use A, you should first reprogram the
Remote Base Prefix Code so as not to use A.
