NETLink PRO ETH

Troubleshooting

Q: I connected the NETLink PRO ETH directly to my PC/notebook but it
doesn't work.

A: A direct connection between two NIC (network interface card) interfaces
is not possible. You need a cross-over adaptor (Order no: NETLINK-
CROSS) or a switch/hub for connecting two Ethernet terminal devices
together.
