Random message channel and repeat interval must be enabled in the TX320

configuration. If random messages have not been enabled, command 3 will

fail. If the GPS acquisition fails, the random transmission will fail. Command

3 will pull the TX320 offline. After the random transmission attempt, the

TX320 must be put back on line with command 6. When command 6 is used,

all data in the TX320 is erased. Random transmission may require up to five

minutes (GPS timeout) for setup and transmission. If command 6 is executed

before transmission, random transmission will be canceled.

During GPS acquisition, the LED will light solid green. During transmission,

the LED will light solid red. Command 3 will return 1 value, the command

result code. Zero indicates a successful execution of command 3, but does not

indicate the random transmission has happened or was successful.
