The Beck Digital Control Module (DCM-2) is
equipped with a serial interface which allows for
direct communication with a computer. Using
a communication cable, connect the DCM-2 to
the computer using the DCM-2’s RS-232 (J20)
connector (see illustration on this page) and the
computer’s COM port. Ensure that the COM port
on the computer is active, and that the cable is
plugged into the proper COM port if more than one
is present (e.g., COM1, COM2, etc.). Note that a
plug end adapter may be necessary for connection
to the computer’s COM port.

Once connected, communication can be
established between the DCM-2 and the computer
using a terminal emulation program, such as
