Com Link board Configuration
The Com Link board is a small circuit board
attached to the TCI-3 base board.The TCI-3 is
shipped with the Com Link board in the iso-
lated Com 3 position as shown in Figure 2,
but can be configured to communicate using
the Non-isolated Com 3 or Com 4 mode as
shown in Figure 3.
To change the configuration of the TCI-3
board:
1. Remove the four screws that attaches the Com
Link Board to theTCI-3 base board.
2. Gently lift the Com Link Board off theTCI-3 base
board and away from the pin set located above
TB1.
3. Rotate the Com Link board 90° so that the non-
isolated Com 3 or Com 4 connector is above
the pin set.

4. Gently lower the Com Link Board over the
pin set and onto theTCI-3 base board.
5. Screw the Com Link Board to theTCI-3 base
board with the four screws that were
removed in step number 1.

Settings for Version I (Comfort Man-
ager),Version II and Version III (Op-
tional Touchpad Display) VariTrac
The TCI-3 board is supported by VariTrac Ver-
sion I (Comfort Manager), Version II, and Ver-
sion II (Optional Touchpad display).The TCI se-
rial Comm link must be in the same daisy chain
as the VAV box serial Comm link.The Comm
link board must be positioned for non-isolated
Com 3 or Com 4 position.Verify that the TCI-3
DIP switch settings are as shown in Table 3.
TCI-3 DIP Switch Address Settings
The DIP switch (SW1) is located on the upper
right corner of the TCI-3 board. DIP switch SW1-
1 is used to enable (ON) or disable (OFF) the op-
tional High Temperature Limit Switch binary in-
put (TB2 on the TCI-3 board). DIP switches SW1-
2 through SW1-6 are used to set the Voyager Mi-
cro Rooftop TCI-3 addresses.
Settings for Tracker/ComforTrac
The TCI-3 board is supported by Tracker/
ComforTrac Building Management Systems. The
Com Link Board must be positioned for Isolated
Com 3 communications. A maximum of 12 Voy-
ager Micro Rooftop TCI-3’s can be defined for
each Tracker/ComforTrac system.

Settings forTracer 100 Series
Panels and Tracer Summit Sys-
tems
The TCI-3 board, which is mounted on the
Voyager Micro Rooftop Unit Control Panel,
is supported by Tracer 100 Series panels
using Version 12 software and Tracer Sum-
mit systems.
Tracer Version 12 software introduced a
new system addressing scheme which al-
lows an operator to configure a maximum of
64 Tracer addresses out of an available
range of 1 through 81.
Tracer Version 13 is the latest software ver-
sion that has a maximum of 32 Voyager Mi-
cro Rooftop TCI-3’s that can be defined for
each Tracer 100 and Tracer 100i. A maxi-
mum of 20 Voyager Micro Rooftop TCI-3’s
can be defined for each Tracer L and Tracer
Monitor.
Note:The amount ofTCI-3’s supported
byTracers is dependent on the soft-
ware version being used. Refer to the
Tracer 100 Series literature for specific
quantities.
The range of Tracer address numbers that
may be defined for Voyager Micro Rooftop
TCI-3’s is 50 through 81. To configure an ad-
dress for a Voyager Micro Rooftop unit, assign
it’s point number (i.e. 30-01, 30-02, 30-03,
etc.) to a Tracer address within the acceptable
range (50-81) as shown in Table 4. Set the
TCI-3 DIP switches for this address.
