Set trigger mode (TM)
Command:
Response:
Permitted parameters:
Activating trigger mode interrupts a command running on the <Ident channel>.
If trigger mode is activated with <Trigger mode>=1 (=2), dampening the trigger sensor
generates the status 0 (5) and after changing to undamped state, generates the status 5 (0) as
a response to the <Sensor channel>. Activating trigger mode generates a response that
includes the current status of the sensor on the <Sensor channel>.
If a read/write command is sent to the triggered channel <Ident channel> when trigger mode is
active, this command is always activated if the <Sensor channel> transmits status 0. <Ident
channel> transmits status 0 to confirm receipt of this command.
If you set <Ident channel> 0, the signal is transferred without influencing a reading head.
The command activated by the <Sensor channel> initiates execution as if it had just been
restarted by the host.
The command is deactivated again if the status of the <Sensor channel> changes to 5 or
trigger mode is deactivated.
If the <Sensor channel> requests a version message, the response contains the status 0 and
no other information.
