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.

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
