Operational Settings
Use a small screwdriver to press on the latches
(indentations) at the top and bottom of the
housing. Slide the housing open.
The transmit optical power level default jumper
position setting is "H" (High). Select position "L"
(Low) only in overdriving (short fiber) conditions.
Jumper Locations
Each module of the modem must be configured
based on the network topology to be used. This
is accomplished by positioning a single jumper in
each module.

Close the housing by sliding it back together until
both the top and bottom latches "click" into place.
DIN Rail Mounting
Installation on DIN rail:
Place the top lip of the module's DIN rail mounting
channel onto the DIN rail. Push the lower portion
of the module towards the mounting surface until it
"clicks" and locks into place.
modules together such that the module sides are
touching ensuring a good connection of the
integrated BUS interconnection at the rear of the
modules. Install End Clamps (Model 2A09) to both
sides of the module bundle to prevent accidental
unplugging of the BUS interconnections. The End
Clamps also provide convenient screw terminals
for connecting the DIN rail to Protective Earth (PE)
ground.
Removal from DIN rail:
Remove the End Clamps from the module bundle.
Disconnect the BUS interconnections by sliding the
modules at least 1/2" apart from each other on the
DIN rail. Insert a screwdriver into the rectangular
hole in the metal mounting latch at the bottom of
the module.
Pushing up on the screwdriver's
handle causes the latch to move downward and
disengages it from the DIN rail. Tilt the module up
and lift it off of the DIN rail.
