Note 1: When MAC filtering is disabled, the Bridge becomes an
Ethernet repeater. Filtering enabled is the default mode for Bridging.
However, the units are shipped with their configuration switch set for
"repeater" mode.
Note 2: When the Ethernet negotiation is set to "auto", the settings for
speed and duplex are ignored. For legacy equipment which does not
support auto-negotiation, it is highly recommended to place SW1-3 in
the ON position and manually set the speed (10 or 100) and duplex
mode to match the connected Ethernet equipment.
Note 3: There is a 340 byte buffer that may be set in one of three
operation modes: equal division (170 bytes each) between the LAN
and WAN ports; large portion (308 bytes) allocated to the WAN port;
or large portion allocated to the LAN port. When the WAN speed is
set slow, efficiency may be increased by allocating a larger buffer on
the WAN side.
