5.2.1 PJTR Sentence
The PJTR sentence is a proprietary sentence that is used for communication between the master and slave P-8300 MkII dis-
play units.
The first parameter of this sentence is the sentence code for our proprietary sentences. The remaining parameters depend on
the sentence code that is sent.
The 8300 MkII has the following three proprietary sentences:
•
Sound Reception Signal (SRS)
•
Volume (VOL)
•
Heartbeat (HBT)
5.2.1.1
SRS Proprietary Sentence
When a sentence code of the PJTR sentence is sound reception signal (SRS), the sentence is a detection notification. This
sentence is sent from the master unit to the configured transmission group such that the slave(s) can receive them.
The SRS sentence has three additional parameters:
Description
Type
Direction of the detection
An integer between 0 and 359 inclusive.
Score of the detection
Score with decimal point when required.
Base frequency of the detected signal

VOL Proprietary Sentence
When a sentence code of the PJTR sentence is volume (VOL), the sentence is a volume adjustment notification. This sentence
is sent from both the master and the slave units when an individual adjusts the volume using the control button on the display
unit. The sentence is sent on the configured transmission group. When a p-8300 MkII display unit receives a message, it
automatically adjusts the volume to match the volume of the device that sent the sentence.
