Commissioning
Information for the network administrator
If the DCS2501 and the BMS communicate via the Internet, the DCS2501 requires a public IP
address at which it can be reached by the BMS.
The DCS2501and the BMS can also communicate via NAT if port forwarding is activated for all ports.
VPN can also be used, e.g. via the Kieback&Peter technoWay.
The bandwidth required for DCS2501 is less than 200 kbit/s.
The network’s “ping” response time must be less than 200 ms.
The network’s maximum downtime must be less than 20 ms.
The standard Ethernet MTU should be 1500 bytes. DSL routers often use a smaller MTU. If this is
the case, the Ethernet packets from the DCS2501 and the BMS are sent in fragmented form.
Adjusting the router’s MTU improves the performance.
If the IP address is assigned via DHCP, the BMS must have a fixed IP address. This fixed IP address
will be provided to the Kieback&Peter representative setting up the BMS.
The following ports on the DCS2501 must be accessible from the BMS:
■
Port 22 (SSH):
For encrypted data communication with the BMS.
■
Port 23 (SSH/Telnet):
For low-level analysis of the device by Kieback&Peter Support (optional).
■
Port 80 (HTTP):
For configuring the DCS2501 via the implemented web server (optional).
■
Port 19280 (DDC/IPC):
For configuring the IP address. The IP address can be configured using an XML frame sent as a
broadcast (optional).
