7.2 COM 
Server 
7.2.1 General 
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. 
7.2.2 Network 
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.
