The DMX1-USB and DMX2-USB are interfaces you can use to connect one or
several measuring devices with DIGIMATIC interface to a PC. The DMX1-USB
provides one DIGIMATIC interface, the DMX2-USB provides two
DIGIMATIC interfaces.
In what follows both device versions are referred to
simply as DMX-USB.
Optionally you can connect a foot switch to the DMX-USB to trigger the
transfer of measured values. Use the USB cable for connection to the PC. The
device is also powered through this cable.
When you connect the DMX-USB to your PC for the first time, you are
asked to install a device-specific driver. Use the CD provided which contains
the required driver, driver installation instructions and these operating
instructions. When you install the driver, you will also install a virtual COM port (VCP). This provides your PC
software with a serial interface (e.g. COM3)
which allows you to control the DMX-USB. See MUX10
Data Format.
Caution: Insert the 8cm CD only into a CD-ROM
drive with appropriate tray!
Connect the measuring device and if required a foot switch to the
DMX-USB. Then use the USB cable to connect the DMX-USB to the PC. When you
connect the DMX-USB to your PC for the first time, Windows will detect new hardware. You will be asked to install its
driver. The driver installation will also install a virtual
COM port (VCP). After the installation check in the Device Manager to see which number has been
allocated to the VCP (DMX Serial Port).
Set your PC software to the correct number of the new communications port.
Make sure that you read the Driver Installation
Instructions on this CD. They explain how you can change the communications port number if your PC software
cannot access the allocated number.
After the driver installation you can temporarily unplug the DMX-USB
from your PC/notebook if you want to use the USB interface for other purposes
or transport your notebook. The DMX Serial Port
and USB Serial Converter won’t be
displayed anymore in the Device Manager.
However, the communications port number
will continue to be reserved for the DMX-USB.
When you reinsert the DMX-USB make sure that you use the same USB
interface. Otherwise the driver will be installed again, allocating another
communications port number. Start the PC software only when the DMX-USB is
connected. Otherwise the software might not be able to open the communications
port.
Measured values can be
transferred in three different ways.
1.
The PC software sends a prompt character. See Advanced Command Set.
2.
A transfer of measured values
is triggered on the measuring device itself, e.g. by pressing the Data button.
3.
The foot
switch is pressed. This transfers the values of all unlocked measuring
devices.
The Data format corresponds
to that one of the MUX10.
9600 baud, 8 data bits, no
parity, 1 stop bit, no handshake
These values have to be set
in your PC software.
All commands have to be
concluded with a carriage return (13hex).
0C/R Measuring device is read (only DMX1-USB)
BC/R Both measuring devices are read (only
DMX2-USB)
1C/R Measuring device 1 is read
2C/R Measuring device 2 is read
D0C/R All measuring devices are locked
D1C/R Measuring device 1 is locked
D2C/R Measuring device 2 is locked
E0C/R All measuring devices are unlocked
E1C/R Measuring device 1 is unlocked
E2C/R Measuring device 2 is unlocked
A measured value always
consists of 12 ASCII characters concluded by C/R.
Example: 01A+1234.567C/R
1st character 0 Measured value ID With measured values always = 0
2nd character 1 Canal number Specifies the measuring device
number
3rd character A Measured value ID With measured values always = A
4th character + Sign + or –
5th-12th char. 1234.567 Measured value Measured value with variable decimal point
An error message always
consists of 3 ASCII characters concluded by C/R.
Example: 911C/R
1st character 9 Error ID With error messages always = 9
2nd character 1 Canal number Specifies the measuring device number
3rd
character 1 Error code 1
= Measuring device not connected, switched off or cannot be requested from the
DMX-USB.
2 = Data format of the measuring device not supported.
