USING SPARE T-LINKS
T-Link 3.0 identifier codes are preset at
the factory. Using an external Reconfig Jumper
provided with a backup T-Link 3.0 unit, a
T-Link's ID code can be changed enabling a
single backup unit to replace any unit with the
same optimizer code. With the 5842 T-Link, a
unit can be reconfigured as an ID 'A', 'B' or
'C' unit. To temporarily change the ID code of
a T-Link 3.0 unit, power the unit off. Select the
Reconfig Jumper with the desired ID code and
install into the T-Port of the T-Link 3.0 unit to be
reconfigured. Power on the T-Link3.0 unit. The
left LED will flash three short times to confirm the
T-Link2 unit has been reconfigured to the new ID
code. Unplug the Reconfig Jumper and connect
any cables to the T-Link 3.0 unit for normal use.
Do not power off the T-Link 3.0 unit after a new
ID code has been assigned. The change of ID is
temporary. When the T-Link 3.0 unit is powered

shown on the bottom of the T-Link 3.0 unit.
