Guide to the SRX800 Receiver Preliminary
a radio frequency then the receiver starts with either the first radio antenna or
the Radio Master Antenna in the radio group. If this frequency is an acoustic
frequency, then the receiver starts with either the first hydrophone or the
hydrophone master in the hydrophone group.
The following provides an example of how a simple configuration would
proceed with scanning using frequency priority.
In this example, three frequencies are used, two radio and one acoustic, in a
selected frequency table (on s 1 [acoustic], 2 [radio] and 3[radio]). They were
entered into the frequency table in the scan order: {2, 3, and 1}. Frequency
Priority has been selected. The radio group has two radio antennas (4 and 7, and
the hydrophone group has two hydrophones (5 and 8). Antenna 4 is the radio
master antenna and Antenna 8 is the hydrophone master. The scan time is set to
15 seconds. The list below illustrates the order in which scanning would take
place:
• Channel 2 is scanned using radio master 4 for 15 seconds.
• Channel 2 is scanned using radio antenna 4 for 15 seconds.
• Channel 2 is scanned using radio antenna 7 for 15 seconds.
• Channel 3 is scanned using the radio master antenna 4 for 15 seconds.
• Channel 3 is scanned using (radio master) antenna 4 for 15 seconds.
• Channel 3 is scanned using the radio antenna 7 for 15 seconds.
• Channel 1 is scanned using hydrophone master 8 for 15 seconds.
• Channel 1 is scanned using hydrophone 5 for 15 seconds.
• Channel 1 is scanned using hydrophone 8 for 15 seconds.
• The receiver then returns to the Radio Master Antenna and repeats the cycle
until either the scan is stopped, the battery expires, or all of the receiver’s
data memory is used.
Frequencies are scanned according in the order they were entered into the
receiver (scan order). This order also determines which type of device, radio,
antenna, or hydrophone is used first in a scan cycle.
