COMMUNICATIONS
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
HyperTerminal
®
. This method of communication
will allow for configuration, calibration and
verification of drive DCM-2 settings without the
use of custom software applications.

Software
HyperTerminal is the standard ASCII terminal
emulation software provided with Microsoft
®
Windows
®
. If using HyperTerminal
®
, the following
instructions will assist in setup. Note that some
variation to these instructions may be necessary
depending on the version of HyperTerminal
®
being
used.
Once the computer has been connected to the
DCM-2, access HyperTerminal
®
by clicking first on
"Start", then "Programs", then "Accessories", then
"Communications", then "HyperTerminal".
Double-click on the "Hypertrm.exe" icon to start
the program. Once HyperTerminal
®
is running, it is
necessary to set up a file with the proper settings
to communicate with the DCM-2. Proceed as
follows:
1. If prompted to install a modem, answer "no".
Proceed to enter a name (e.g., "DCM-2")
and select an icon (any will suffice) in the
"Connection Description" box. Click the "OK"
button.
2. The "Connect to" box should open next. At
the bottom of the box, set the "Connect using"
selection to the computer COM port that has
been connected to the DCM-2. Click the "OK"
button.
3. The COM port properties box should open next.
This is where the communication settings are
established. The correct settings are:
a. Bits per second = "1200"
b. Data bits = "8"
c. Parity = "none"
d. Stop bits = "1"
e. Flow control = "none"
4. With the appropriate settings entered from Step
3, above, click "OK". Communications should
now be enabled.
5. Press the "Enter" key twice. "Ok" should be
displayed indicating that HyperTerminal
