    3.2.2 Personality Plug-In Boards The EV9000 motherboard has two complete modem circuits. Each circuit includes a modem IC and an accompanying personality plug-in board. There are up to four capacitors on the plug-in board which must be altered for different modem types and data rates. These four capacitors are used in: Rx filtering, Tx filtering, and two for Rx level measurement.

    Printer Port, select which of your PC’s printer ports you would like the EV9000 to use. Upon selecting a printer port from the list, the Port Base Address list will show the default address associated with the selected port. This address is usually correct, however, it may be changed via the Port Base Address pull-down list.

    The EV9000 hardware seems to have spontaneously changed its state (e.g. noise source channel A has changed) without deliberate user action. It is important to power the EV9000 and have it connected to the PC's parallel port before starting the software. This ensures that the hardware is properly initialised. Disconnecting and reconnecting the parallel port or power cycling the EV9000 may create phantom ...
