Jumper Settings (P1X) - Novatech Bitronics M87X Series Manual

8.13.1 Jumper Settings (P1x)

The jumper block allows setting of the Ethernet card to emulate less capable equipment or
to force speed and/or duplex of the network interface. For most systems, the factory
default (no jumpers) will provide the best connection. Use of other modes should be done
only after careful consideration.
