Description
The DE8691 Demonstration Board features the CMX869B V.32 bis modem IC in a "socket modem format" implementation. The "socket modem" section also contains the line interface components and a Flash PIC µC.
Attached to the "socket modem" section are two break-off sections, which contain a 9-pin D type socket for PC serial communications, a Flash PIC programming connector, an RJ11 line connector and various LEDs for indicating signal activity.
AT Commands are used to control the demonstration board via a standard terminal emulator program running on a host PC.
Interfacing to the Demonstration Board can be via socket pins on the socket modem section, or via the connectors provided on the break-off sections. The board is operated at 3.3V dc, which must be provided by an external, regulated power supply.
