RightFax 8.5 Fax Board Guide 11
Setting the hardware interrupt
The Brooktrout TR114 series of analog fax boards also requires you to configure an interrupt setting
on each board. The interrupt value is selected on the board using a jumper (which looks like a small
plastic cap covering two wires). Refer to your Brooktrout documentation for the location of the
interrupt header on your fax board model.
All Brooktrout TR114 fax boards installed in the same computer must use the same interrupt setting.
If a TR114 is already installed and operating, and you add another TR114 board, you must set the
hardware interrupt on the new board to the same value as the currently installed board.
The default interrupt setting for all Brooktrout TR114 series fax boards is 5. You can use this setting
or use any other interrupt setting that does not conflict with other devices on the computer. On
some computers, interrupt 3 may cause a conflict with the second serial port, and interrupt 4 may
conflict with the first serial port. If all of the Brooktrout TR114 boards are installed in 16-bit slots,
interrupts 10, 11, and 15 are often your best choices.
Note If you have a combination of ISA and PCI TR114 fax boards, you must set the interrupts used by your
ISA cards as “ISA only” in your server BIOS.
Installing Brooktrout TR114 fax boards
Fax boards can be installed in the RightFax server or in a separate computer called a “remote
BoardServer.” For information on using remote BoardServers, refer to the RightFax Administrator’s
Guide.
Warning Never insert a loop-start line into a DID port. Doing so will damage the fax board and void all
warranties. If you have any doubts, test the phone line with a volt meter prior to connecting it to a DID port to
ensure that no current exists on the line.
After all of your Brooktrout TR114 fax boards are configured to use the proper
I/O addresses and hardware interrupt, you are ready to install them. Always turn your computer
off before inserting or removing any board, and take all necessary precautions to prevent static
discharge when handling any fax board. ISA TR114 boards can be installed into either an 8-bit or 16-
bit slot in an ISA or EISA computer. PCI boards can be installed in any PCI bus slot.
After the fax boards are properly installed, refer to your Brooktrout documentation for instructions
on connecting the DID and/or loop-start phone cables and optional power supply.
Completing the installation of your Brooktrout TR114 fax boards
After your Brooktrout TR114 fax boards have been installed, you should test the fax channels to
ensure that the boards have been properly configured and installed. For information on testing your
fax channels, see “Testing Brooktrout Loop-Start Boards” (page 14), and “Testing Brooktrout DID
Boards” (page 15).
When you have completed installing and testing your Brooktrout TR114 fax boards, you must
configure the RightFax software to communicate with the boards. For information on configuring
RightFax to work with your fax boards, refer to the chapter on configuring the RightFax
BoardServer in the RightFax Administrator’s Guide.
