•
Not all parameters associated with a command need to be specified. Depending on the command,
when a parameter is omitted it either assumes a default value or keeps the last value assigned to
that parameter.
•
For all parameters that accept a numeric value, the number can be entered in decimal,
hexadecimal, or octal notation. To enter a number in hexadecimal notation precede it with a 0x
or 0X. To enter a number in octal notation precede it with a 0 (zero). All other numeric values
are interpreted as decimal. Example:
> rf-receive ch=0x1a (hexadecimal)
> rf-receive ch=014 (octal)
The following sections describe the various commands grouped according to their functionality. A
summary list of all commands are contained in Appendices A and B.
4.3 Configuration Management Commands
A radio configuration consists of a set of programmable parameters that define the radio operation
with regard to a variety of operating modes. There are five different configurations identified as
current, main, alternate, factory and basic .
The main and alternate configurations are both stored in non-volatile memory. They can be loaded
into the current configuration with the load command. On power up the radio loads the main
configuration from non-volatile memory into the current configuration.
The current configuration is the set of parameters currently being used and can be modified by the
operator through several commands. This configuration is volatile. If the current configuration has
been modified it should be saved using the
save command. Otherwise the modifications will be lost
if power is removed.
The factory configuration can not be modified by the operator and is used to return the radio to the
factory default condition. It is useful as a starting point to create a customized configuration.
The basic configuration is similar to the factory configuration with the exception that a few
parameters are left unchanged when you issue the load basic command. The parameters left
unchanged are the RF and the IP configuration. This is useful when you are logged on to a remote
unit and need to start from a known configuration. If you were to issue the
load factory command
you might lose contact with the remote unit if, for example, it changes the antenna of the remote
radio.
The access to change the radio configuration can be password protected. This password is set by the
user with the
change-password command. Once a password is set, issue the lock command to
prevent any unauthorized changes to the configuration. Once locked, the configuration can only be
modified by issuing the
unlock command with the correct password.
When the configuration is unlocked, the radio prompt ends with the characters ‘#>’ to remind the user
that the configuration is unlocked. In locked mode the prompt does not include the ‘#’ character.
Once a password is set, the radio will automatically lock the configuration after 10 minutes without
any commands being issued.
