Nokia M-Bus, Bosch C-Bus universal data-cable

Most common scheme of m-bus and c-bus interface cable. Suitable for most Nokia (M-Bus) and Bosch 508, 509, 607, 608, 718, 738 (C-BUS) cell phones

9 pin D-SUB female connector  to the computer

This simplified M-Bus scheme should be used with most Nokia cell phones (i.e. Nokia 8210, 8850)

In some cases (for Bosh cell phones?, Nokia 3210) more complicated scheme should be used

External power usually not needed, but may be used
