How to identify transmit labels for a particular equipment in ARINC429? As i can see, each equipment has a set of labels which the equipment may supposed to be received. Say if i am Equipment 03Ch (Tire pressure monitoring system), i will be configured to receive below labels
LABEL 060 -&gt; Tire pressure (Left Outer)
LABEL 061 -&gt; Tire pressure (Left Inner)
LABEL 062 -&gt; Tire pressure (Right Inner)
LABEL 063 -&gt; Tire pressure (Right Outer)
LABEL 064 -&gt; Tire pressure (Nose)
But how may i know, what are the labels should i send ?
As Gerry mentioned in their comment, the equipment ID label (377) indicates to the receiver how to decode the labels being received on that ARINC 429 channel.
The transmitting equipment (Tire Pressure Monitoring System) would send label 377 with the value 03C at it's appropriate rate (usually every 1000 ms) and then labels 060 through 064 at their appropriate rate.
The receiving equipment gets the Equipment ID from label 377 it received and then knows to decode labels 060-064 according to the TPMS definitions.
