The ETC tag has Tamper and Button Press inputs; designated
B1 and B2:
 B1 – Monitors press/ release button activity
 B2 – Monitors tamper functionality
 
The ETC tag reports the state of the tamper sensor on B2. When
Tamper is detected (detached), B2=1. When attached, B2=0. An
EVENT message is transmitted when there is a change from
attached to detached or vice versa. When there is a change from
attached to detached (i.e. tampering), then there is a transmission
of EVENT of 4 messages, 400 ms apart and B2=1. When attached,
there is a transmission of EVENT of 4 messages, 400 ms apart
and B2=0.
In the steady state, the B2 bit provides the status of the tamper
sensor (if the equipment tag stays attached, B2=0, if stays
detached, B2=1).

After button press, 4 messages are transmitted (each message
about 2ms in duration), 400 ms apart, with B1=1. When the button
is released, B1=0.
An additional 4 messages (each message about 2ms in duration)
are transmitted 400 ms apart. In the steady state (no button press /
button release) B1=0.
