The parameter defines the heartbeat period time in seconds. If the value is set to 0, there are no heartbeats, only one heartbeat is sent to the Dension Sherpa system (upon startup). This is not recommended, because it makes maintenaning the device remotely impossible.
The ‘Internet’ light goes off only in case there is no answer from the Dension Sherpa server. This may happen if the ethernet-line has been disconnected, network settings have been changed or communication has been blocked by a firewall.
See appendix 7.3 for a table of available scan codes. 5.2GPIO control The devices may be extended with an additional GPIO capability via the USB port. Dension's relay extension cable provides a 230VAC/2A capable relay contact to control an external device's power.
The Dension Sherpa is a Web2.0 based application developed for the maintenance and operation of the ISR and MPX devices over the internet. It runs as a cloud service, hosted on Dension's servers and all devices are connected to it.

•MESSAGE: the message of the log. This field contains the relevant information of the log event. Logs are reported to the Dension Sherpa service during heartbeats. For this reason it is important to allow the device to report to the Dension Sherpa service periodically. If the device is not network enabled for a long time some logs might be lost, due to limited storage on the device.
