SW6, SW7, SW8 - Link Modes
These three DIP-switches configure the link mode settings. DIP-switch SW6 is valid
when Port 1 is set to “AN” or “MAN”. DIP-switches SW7 and SW8 are ignored when
Port 1 is set to “AN”. The following table details possible Link Mode DIP-switch
configurations.

NOTE: Connecting two converters set to any of the RFD modes is illegal and will
cause a “deadly embrace” lockup.
NOTE: It is recommended to keep the LS setting (default) until initial configuration
is complete.
For detailed information on the operation of the different Link Modes, download the
application note “iConverter Link Modes” available on Omnitron’s web page:

2) SET-UP MODULE AND CONNECT CABLES
a. The Gx AN is available in tabletop and wall-mounting models. For wall-mounting,
attach the unit to a wall, backboard or other flat surfaces. For tabletop installations,
place the unit on a flat level surface. Attach the rubber feet to the bottom of the unit
to prevent the unit from sliding. Make sure the unit is placed in a safe, dry and
secure location.
To power the unit using the AC/DC adapter, connect the AC/DC adapter to the AC
outlet. Then connect the barrel plug at the end of the wire on the AC/DC adapter to
the 2.5mm DC barrel connector (center-positive) on the chassis. Confirm that the
unit has powered up properly by checking the power status LED located on the
front of the unit.
To power the unit using a DC power source, prepare a power cable using a two-
conductor insulated wire (not supplied) with a 14 AWG gauge minimum. Cut the
power cable to the length required. Strip approximately 3/8 of an inch of insulation
