AUX Input Status Message 1 to AUX Input Status Message 3
AUX Input Status Message 1 to AUX Input Status Message 3 are the trigger ports that are used to send a FleetSync,
NXDN, or DMR Status Message.
The transceiver sends a Status Message configured for each port to an ID configured for Target ID (FleetSync), Base ID
(NXDN), or Base ID (DMR) when the port goes high level to low level or goes low level to high level.
Two statuses (High N Low, and Low N High) can be configured for each port of AUX Input Status Message 1 to AUX Input
Status Message 3 by using KPG-D1/ D1N. These ports are normally used as the sensor ports for telemetry purposes.
Note
The transceiver does not send a Status Message immediately after the transceiver is turned ON since the transceiver
0
does not recognize that the AUX Input port to which "AUX Input Status Message" is assigned has changed.
If the logic of the port is not changed, the transceiver does not send a Status Message when the analog channel is changed
0
to an NXDN or DMR channel. However, the transceiver sends a Status Message if conditions to send the Status Message
are satisfied.
Zeroize
Zeroize is the port that is used to delete an Encryption Key configured for the Secure Cryptographic Module (SCM).
If the port remains active for the amount of time configured in Zeroize Delay Time, the transceiver determines that the port
is active. When the port is activated, the Encryption Key configured for the SCM is deleted.
If "Zeroize" is assigned to the AUX Input port, the logic of the port can be configured Active High or Active Low. The
transceiver behaves as follows according to the logic of the port:
The Logic of the Port
This logic is used to delete an Encryption Key by user operation, such as using the Foot Switch.
Active Low
All Encryption Keys stored in the SCM are deleted if the port is continuously detected as active
for the amount of time configured in Zeroize Delay Time.
This logic is used to automatically delete an Encryption Key when the transceiver is turned ON to
avoid any leakage of encrypted information, such as when the transceiver is stolen.
Active High
If the port is active when the transceiver is turned ON, all Encryption Keys stored in the SCM are
automatically deleted regardless of the configuration in Zeroize Delay Time.
Scan
Scan is the port that is used to activate the scan function.
When the Scan port goes low level, the scan is started. When the Scan port goes high level, the scan is stopped.
