Auto-MDIX Jumper
Note: The factory settings for Auto-MDIX will work for most
installations, but if there is a need to modify the settings, follow the
procedure below.
The AUTO-MDIX jumper (J5) is located on the upper edge, at the
midpoint of the module (see diagram below for labelling).. By covering
or strapping pins 2 and 3(AUTO), the C-110 and CM-110 will
automatically detect the Ethernet cable’s polarity and configure itself
as either an MDI or an MDIX device. By covering or strapping pins 1
and 2(MDIX), the C-110 and CM-110 will operate as an MDIX device
Removing the strapping is the same as AUTO.
NOTE: The default jumper setting is AUTO
