Module LH8100C-2TX
Module LH8100C-2TX is either an internal bridge for bridging the
internal 10Mbps and 100Mbps segments or an external 10/100BASE-TX
distance extender with MDI-X and MDI-II interfaces using an RJ-45
cable. Only one of these functions can be enabled at one time. The
internal or external bridge must be enabled or disabled with on board
jumpers before installation. Module flow-control (backpressure) can be
enabled or disabled by setting the on board jumpers before installation.

•
Bridge Function setting: Internal (Default)
•
Backpressure setting: Disabled (Default)
