‘Status Request’ Command Format:
Status FFF.FF
‘Remote Audio Listening’ Command Format:
Listen FFF.FF
Where FFF.FF is the frequency to Tune in the range of 87 to 108 MHz.
For example: “Status 102.55” or “Listen 88.80”.
IMPORTANT:
Do not include leading zeroes such as “Listen 089.90”. Fill in with trailing
zeroes up to two digits after the decimal symbol. Decimal symbol must be “.” (dot)
If DB44 receives an authorized ‘Status Request’ command, after a short interval (about 5
seconds), in which DB44 has to retune and collect summarized data, the Caller will receive a SMS
response. For Example:
STATUS:
27.09.2011 09:08:34
FREQ:102.50MHz
RF:32.7dBuV
MPX:103.2kHz
Left:-4.8dB
Right:-4.9dB
Pilot:7.5kHz
RDS:18.5kHz
‘Remote Audio Listening’ command will generate (only if the calling number is authorized) a
response call from DB44 to the command sender. DB44 will wait for answer, and will hang-up
after 30 seconds, if there is no incoming answer. When a call is accepted, the duration of ‘listening’
is determinate by ‘Call Duration’ interval or until the call is ended.
