4.4 Detailed Command Descriptions

The only critical commands for most applications are transmit and

receive frequencies (

RX xxx.xxxx, TX xxx.xxxx). 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 provides

more detailed information for the user commands previously listed in

Table 9 (Page 17).

In many cases, the commands shown here can be used in two ways:

• You can type only the command name to view the currently pro-

grammed data.

• 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,

acceptable programming variables, if any, are shown in brackets

following the command name.

ALARM

The

ALARM command displays a summary of the radio’s current oper-

ating condition. An eight-digit hexadecimal code is presented that can

be decoded as described in “Major Alarms vs. Minor Alarms” on Page

30.

AMASK [0000 0000–FFFF FFFF]

Alarm Mask The AMASK command displays or sets a mask indicating which events

cause the alarm output signal to be active. Normally, the mask is

FFFF

, meaning that any of the 32 possible events can activate the alarm

output signal.

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.

TX [xxx.xxxx] Details Page

TXLEVEL [–20 to +6,

AUTO] Details Page 29
