4.4 Detailed Command Descriptions
The only essential commands for most applications are transmit
frequency (
TX xxx.xxx
), receive frequency (
RX xxx.xxx
), and network
address (
ADDR xxx
). However, proper use of the additional commands
allows you to tailor the transceiver for a specific use or conduct basic
diagnostics on the radio. This section gives more detailed information
for the user commands previously listed in
.
In many cases, the commands shown here can be used in two ways.
First, you can type only the command name to view the currently
programmed data. Secondly, you can set or change the existing data by
typing the command, followed by a space, and then the desired entry. In
the list below, allowable data values, if any, are shown in brackets
following the command name. The separator symbol (|) indicates that
you can enter one of the values in the list.
ADDR [NONE | 1–255]
The
ADDR
command displays or sets the network address of the radio. In
order for all the radios in a network to communicate, their network
addresses must be identical, or set to
NONE
. (The radio is shipped from
the factory with
ADDR
set to
NONE
.)
AMASK [0000 0000–FFFF FFFF]
The
AMASK
(alarm mask) command displays or sets which events cause
the alarm output signal to be active. Normally, the mask is
FFFF FFFF
,
meaning that any of the 32 possible events activate the alarm output
signal. No special configuration is required for typical applications.
Entering the
AMASK
command alone displays the current setting of
alarm events in hexadecimal format.
Entering the
AMASK
command followed by an eight-digit hexadecimal
number reprograms the specified events to trigger an alarm.
Each bit that is a ‘1’ identifies an associated alarm condition that can
trigger the alarm output status line. Each bit that is a ‘0’ treats the
associated alarm as irrelevant when deciding whether or not to assert the
alarm output status line.
Display the current alarm status.
Set or display the time-out timer status and the
timer delay in milliseconds.
Set or display the transmit frequency.
