IC-KP-R2-V1
Commands
Reset to defaults (RD):
Command:
Response:
This command terminates all active commands. The control unit is reset to the factory settings.
Note!
The device settings stored in the non-volatile memory always become active after a reset.
Set multiplexed mode (MM):
Command:
Response:
This command activates or deactivates multiplex mode. In multiplex mode, the transmitters of
the R/W heads are controlled according to the time multiplex process, i.e. only one R/W head
is active at any one time so that mutual interference is minimized, allowing two R/W heads to be
mounted side by side.
Each IDENT channel responds to an MM command and four response telegrams are sent
back.
Multiplex mode
Set trigger mode (TM):
Command:
Response:
Permitted parameters:
<Sensor channel>
<Ident channel>
<Trigger mode>
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.
