You need a fax application to use a TruFax® BRI
board. Dialogic does not provide the application or a
driver for this board. A driver comes with the
application that you purchase.
Use the SW-1 rotary switch (Figure 1) to set a unique
module number for each Dialogic® Brooktrout®
board. See Figure 5 for the switch location. Select a
number from 2 - F on the rotary switch. Settings 0 and
1 are reserved and cannot be used.

Getting Help
4. Carefully align the board with the slot and firmly
seat the board into the slot.
Connect to Port A for channels 0 and 1 or to
Port B for channels 2 and 3 (see Figure 5 to
locate ports).
5. Tighten the mounting bracket screw to secure the
board to the chassis.
2. Plug the other end into the wall connector for
your BRI service.
Warning: When installing the board, be sure that the
mounting bracket is securely fastened to the chassis and
the chassis is plugged into a grounded three prong plug.
Improper chassis or bracket grounding can result in
harmful or fatal electrical shock as well as component
damage.
Note: Port B is not present on the TruFax® BRI single port
version.
