22 Chapter 3 Dialogic Analog Fax Boards
The following table lists all of the Dialogic analog fax boards supported by RightFax.
Warning The voltage level supplied by the CPD/220 fax board is considered dangerous. Never operate the
system when the chassis cover has been removed.
Setting the I/O address
Before installing your Dialogic fax boards, you may need to manually set the base I/O address of
each board.All fax boards are shipped from Dialogic with a default I/O address of 350. If more than
one fax board is installed in the same computer, this will result in an I/O address conflict. All of the
channels on each installed Dialogic board must have a unique I/O address.
Warning Do not use a pencil or any other object that conducts electricity to move DIP switches on any fax
board. Using graphite and other electrically conductive materials may cause severe damage to the board.
On the Dialogic CP, CP1, CPi/100, and CPD fax boards, the I/O address is set using six DIP
switches located on the mounting bracket. On the Dialogic CP4/LSI, CPi/200, and CPD/220 fax
boards, the I/O address is set using three DIP switches on the unit marked “SW1” on the fax board.
Refer to your Dialogic documentation for the location of the I/O address DIP switches on your
particular fax board.
Note The Dialogic CPi/200 PCI and CPi/400 PCI fax boards do not require you to set I/O address values.
Instead, these board models include a rotary switch that lets you specify a unique identifier number for each
installed board. For information on setting the unique identifier on these board models, see ”Setting the
board identifier” on page 24.
The I/O setting represents the first channel on the board. Any additional channels on the board
automatically use the next I/O addresses in sequence. If you are installing multiple boards, make
sure that the I/O address settings do not overlap. Any changes to the I/O address DIP switches
must be made before the fax board is installed.
