RaceAmerica 5842 Wireless SBD Timer
After each race, the timer is locked out for
ten seconds to allow dirt and dust to settle.
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
off, the ID code will revert back to the preset ID
shown on the bottom of the T-Link 3.0 unit.
BATTERY CHARGE
Charge the USB Battery Pack using the
an external USB charger unit. All functional
electronics are disabled during battery recharge to
avoid damage. Typically a full battery charging
will take 6-8 hours. The charger indicator LED
will turn from red to yelow to green when charging
is complete.
TECHNICAL DETAILS

For RS232 serial data communications, pin two is
ground and pin one is data sent from the T-Link
