7.2COM Server

7.2.1General

The COM server makes the PV inverter data available via an Ethernet network. A software application can communicate with the PV inverter via the network using a virtual COM port (this needs to be installed on a workstation). The COM server is in- stalled as standard and is used by the AEG service department for remote maintenance purposes. This calls for an appropriate Ether- net network with an Internet connection plus a fixed IP address as- signment.

The COM server is located at position A27.

7.2.2Network Connection

This COM server has an IEEE 802.3-compatible network connec- tion on a shielded RJ45 plug connector. Its assignment corre- sponds to that of an MDI interface, which means the connection to the hub or switch is made using a 1:1 wired patch cable.

Ex-works, the COM server operates in an autonegotiation mode on the network side. This means the data transmission speed and the duplex process are automatically negotiated with the connected switch or hub and are set accordingly.
