Heartbeat monitoring
The heartbeat protocol is for monitoring the activity of communication
partners. If the inactivity exceeds the set interval (Heartbeat consumer time),
the status is set to offline .
The application program lets you define heartbeat functions, such as
 Displaying information to the user

Rebooting the device
 Ignoring process data
Heartbeat monitoring is available only for specific devices and its availability
depends on the OS version.
Device OS version

JVM-C02 4.00.0.00 or higher
JCM-350 1.09.0.215 or higher
JCM-620 JVER bersion 3.2.2.645 and JetVM version 3.04.0.00
or higher
