Connecting Data Ports
Ethernet Connection
By default the 10/100/1000 Ethernet port will automatically set itself up to match the
speed of the port it is connected to. If auto negotiation is not supported by that port
then, the port can be configured to operate at a fixed speed and duplex settings.
To connect to 10Base-T, 100Base-TX or 1000Base-T follow these steps:
1. Connect a straight through Ethernet cable from the IOLAN SDS2 L Ethernet port to an
10/100/1000 RJ45 port on the network hub/switch.
2. Once the IOLAN SDS2 L is connected and the link is established, the link LEDs will turn
on. These LEDs will indicate whether you have a 10, 100 or 1000 Mb/s link to your
hub/switch. See. (LED Indicators) for more details.
