• Ideal for supporting encoder redun­dancy without a DTA

• Automatic or manual switching

• Auto rate detection

Benefits

• Inputs (2):

(A) Primary input
(B) Secondary input used as a backup

• Front panel LEDs (2):

Power - Green indicates powered up
Signal - Green indicates a valid signal is being

passed through the system.

Modes selectable via external RST (2):

-When LEFT and CENTER terminals are shorted
together the PRIMARY signal passes.

-When the RIGHT and CENTER terminals are
connected the SECONDARY signal passes.

-When any of the previous two modes are selected
the unit will not use the redundancy backup
signal. When the unit is not in manual override
mode it uses the secondary signal as a backup.

• Redundancy Backup

When signals on both the primary and secondary are
valid the primary signal will pass. If this signal is
lossed then the secondary signal will pass. If there is
no secondary and primary signal, no input passes.
Once a valid signal is connected the unit will then
pass that signal, however the primary input takes
precedence so if both signals are again connected
the primary will pass. If the primary is lossed again
the unit switches to secondary. If the primary is then
reconnected it will go back to passing the primary. All
inputs use autorate detection.
