To establish a modem connection
• Make sure that the attendant at the site location is aware that a modem connection will be taking place. (Use
of the automated attendant can greatly assist the modem connection process by removing the human
element at the site location.)

• The connection is also noted with an icon that appears in the upper left corner of the display: [Mdm].
• Once a modem connection has been accomplished, F4-Connect is possible. F4-Connect is required to link
PC-DBA to the DX-80 system processor.
F10 – RS232C
• F10-RS232C is the utility to setup the PC COM port. To successfully setup the PC COM port you must know
how the PC hardware is configured. In this utility you must select the COM Port number (1 or 2 supported)
and the baud rate that will be used for the connection. At default PC-DBA is setup to use COM Port 1 at
9600 bps. (9600 bps matches the default baud rate set for the DX-80 CPM – PC-DBA Port.)
• While using a modem connection it is best to set the COM port baud rate at 2400 bps since this is the speed
of the DX-80 Optional Modem. (Setting this speed can expedite the modem negotiation process since
compression link choices will not be attempted.)
