NOTE Data will be lost if all software application programs are not closed before
the M4200c is powered down.
To set the M4000 to the Storage and Moving Mode, reverse the previous setup
procedure (”Testing Mode” on page 1-13), keeping in mind that the Safety
Ground cable is the last cable to be disconnected from the M4100 instrument.
Refer also to ”Storage and Moving Mode” on page 1-10.
M4000 PC Cable
There is a cable with connectors designed to attach your M4100 to a third-
party controller of your choice. This cable is supplied as a way to offer users
an even higher level of product reliability. With the M4000 PC Cable, the user
can continue to test even if the M4200c Controller suffers a serious failure, by
using the cable to connect the M4100 Instrument directly to the user’s own
PC.
To be prepared to use this cable, you must have the DTA and M4000 diskettes
available to load onto your computer, and preferably a back-up copy of test
data files as well.
Third-Party
Controller
Requirements
• Pentium Celeron
• 64 megabytes of memory
• Windows 98 or later operating system
• Internet Explorer version 5.0 or better
• One available serial port
See the Doble website (www.Doble.Com) for complete details.
Setting Up the
Controller
The computer must be loaded with the M4000 (and DTA, if a DTA user)
software.
The COM port setting must be set in accordance with your computer's
requirements. This can be done by selecting Configuration from the Tools
menu and clicking the Instrument tab. The COM port is automatically set to
the requirements of the M4200c Controller when you install the M4000
software. If you are using a Serial to USB converter, see ”Instrument
Configuration” on page 2-18. If you have the wrong COM port setting, you
will get a communications error message when trying to run a test.
Besides the COM port setting, you must be sure no other program is running
that wants to access this same COM port. Review programs located in your
startup folder which start up each time the computer is booted up, and remove
any that may try to grab the COM port. Or, from the System icon in the
Control Panel, go to the Hardware tab and select Device Manager. Disable any
items that require the selected COM port.
