Overview<\/h2>\n\n
The expansion modules (Ethernet) integrate numerous inputs and outputs in a compact device. They enable the integration of external alarm messages and measured values in KentixONE. The network-compatible modules are supplied with power either via Power over Ethernet (PoE) or an external power supply unit (10-48 VDC, 4.4 W).  The network settings are configured on the device itself using a web browser. The alarm and display logic is then configured in KentixONE. <\/p>\n\n

Commissioning<\/h2>\n\n
The modules can be supplied with power either via Power over Ethernet (PoE, recommended) or via an external power supply unit. When using a power supply unit, please observe the power supply specifications in the Datasheet<\/a>. <\/p>\n\n
Configuration with KentixONE<\/h2>\n\n
The device is configured via the web browser in KentixONE. The device must be accessible to the central KentixONE instance on the network side. Depending on the device type, a communication key and the IP address or DHCP name of the central KentixONE instance must also be set on the device (MultiSensors, AccessManager, SmartPDU). IP cameras or IO modules, on the other hand, can be integrated directly into KentixONE.   <\/p>\n\n
All information about the software can be found in the KentixONE<\/a> section and the associated documentation.<\/p>\n\n
Before starting the configuration, make sure that the software on all network-compatible Kentix devices is up-to-date. The version status must match on all devices.
You can perform a software update for your KentixONE main instance and all connected satellites at any time via “System – Update”.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
