Beck Configuration Port

Local configuration of the Beck actuator can

be accomplished using Serial commands through

the DCM-3 Serial port.

The Beck Digital Control Module (DCM-3) is

equipped with a Serial interface which allows for

direct communication with a computer. Using a

standard DB9 to USB cable, connect the DCM-3

to the computer using the DCM-3’s DB9 connector

(see below for location) and one of the computer’s

USB ports. Note: If your computer is equipped

with an active COM port, a DB9 to DB9 cable may

be utilized. See below for part numbers of cables

available from Beck.

Once connected, communication can be

established between the DCM-3 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‑3 settings without the use

of custom software applications.

HyperTerminal

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.

After connecting the DCM-3 to the (Windows®-

based) computer, access HyperTerminal

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-3.

Proceed as follows:

1. If prompted to install a modem, answer "no".

Proceed to enter a name (e.g., "DCM-3")

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 appropriate USB (or COM) port

that has been connected to the DCM-3. Click

the "OK" button.

3. The 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

communicating with the DCM-3.
