1 Documentation overview
The complete production documentation of the precision measuring devices
DMP41 (DMP41-T2; DMP41-T6) comprises the following publications:
SThe operating manual 'Digital precision measuring device DMP41-T2,
DMP41-T6' (A3463)
explains the manual operation of the device
SThe operating manual 'Digital precision measuring device DMP41
Interface description and command set (A3462) explains programming
and measurement via terminal or computer, including all HBM interpreter
commands
Important
You are currently reading the ’Interface description and command set’
operating manual.
For operation as a ’stand-alone device’, please use the general operating
manual ’Digital precision measuring device DMP41−T2, DMP41−T6’
(A3470)
1.1 How to work with this manual
Before putting the device into operation please note the following
information:
Important
Please comply with the safety instructions in the operating manual Digital
precision measuring device DMP41 (document number A3470).
This manual - Operation with computer or terminal - is intended to help you
operate the DMP device via a computer as rapidly as possible. It is both
suitable for beginners without PC experience and for experts with computer
experience.

Various guides are available to help you:
SThe table of contents at the beginning of the manual provide an initial
overview.
SThe header shows you which chapter or sub‐chapter you are currently
reading.
SExample:
SThe footer displays the name of the manual (Operating with computer or
terminal, Operating manual, etc.)
SThe page numbers are coupled with capital letters according to the
chapter designations. Each chapter starts with Page 1.
SIf you are looking for individual commands, it is best to refer to the
command overview in Appendix IV or Appendix V.
SThe keyword index contains an index register to help you orientate
yourself rapidly in the manual.
1.1.1 Operation with PC
This manual explains the operation of your HBM device with a computer.
SYou can implement all device settings by sending an appropriate
command sequence from the computer. Automation of repetitive
measurement sequences is possible with a computer and the
corresponding programs.
In order to match up the signals output from or required by the various
devices (computer, plotter, printer, measuring device, etc.), the devices
must be connected together via interfaces.
Interfaces are standardized so that devices from various manufacturers can
be used.
The DMP device can be operated via the following standardized interfaces:
SEthernet interface
SUSB port for RS232
Administrator rights are required for all measurement‐relevant settings
(see also Page 28)

2 Interface comparison
The DMP41 has four different interfaces:
SEthernet
SUSB Host
SRS232 (external adapter on USB Host)
The device can be operated simultaneously via all interfaces, but can only
be parameterized over one connection at the same time.
The HBM Interpreter “translates" the command and corresponding
character string received from an interface into a code understood by the
DMP41.
You can call up the Interpreter via the above‐mentioned interfaces.
All HBM Interpreter commands are shown in Chapter
“5Command set of the HBM interpreter".
This chapter is to help you determine which interface to use. How the
interfaces function can be found in the corresponding Chapter.
