Network Wiring

o
Serial Connection:
The KNX v3.1 modules only support TCP/IP communication. The RS232
interface is described here for legacy purposes.
The CGEIB-IP can be serially controlled over RS-232 via the SUBD 9 on top of
the unit. The following pins are required:
Com pin outs between Crestron COM port and CGEIB-IP RS232 SUBD 9pol.

o
LAN Connection:
The CGEIB-IP can be controlled over TCP/IP by means of the LAN port. This
LAN port is automatically activated when no RS-232 cable is connected.
The LAN port starts a DHCP inquiry only after PowerOn or Reset, i.e. if a
network cable is plugged after PowerOn of the CGEIB-IP, the LAN port does
not fetch an IP address over DHCP. Thus the LAN port is not accessible in the
network.
Best practice: Before powering up the CGEIB-IP, all other connections
should be made!
The CGEIB-IP does not support POE.

Commissioning of the LAN port
The LAN port must be connected to the network. Afterwards, the CGEIB-IP can
be powered on. In case of a direct connection of the LAN port with the PC, a
cross-link connection is needed.
On delivery, the LAN port is already configured.
By default, it is set to automatic inquiry of the IP address. To scan the network
for the CGEIB-IP, please use the Lantronix® Deviceinstaller™.
