Installing a TCP/IP Module
The MICROgarde TCP/IP module can be connected to 100Mb or 10Mb networks. In order to
fully satisfy EU requirements for EMC and RFI, we recommend that this product only be
connected to a 10Mb network port. On a 100Mb network, we recommend connection via a
hub that is limited to 10Mb.
The IP module connects to the top edge of main board (see below).
