Communication connection 
(U)MT51x has a wide variety of communication possibilities to suit specific demands. In the case of
simultaneous use of Ethernet and USB communication, the standard port (COM1) is shared by two
communication channels: COM1A (Ethernet) and COM1B (USB). This allows different users to access
data from (U)MT51x simultaneously and by using Ethernet communication, data can be accessed
worldwide.
Different configurations are possible (to be specified with an order):
Configuration COM1A
1 RS232/485
2 Ethernet
(1)
RS485 communication is available through DB9 or screw-in terminals, while RS232 is available only
through DB9
WARNING!
When connecting a DB9 communication connector it is necessary to assure that only RS232 or
RS485 communication is used. Terminals of a DB9 connector that are not necessary for the
used communication should remain unconnected, otherwise the communication module
and/or device can be damaged or destroyed. See connection diagrams below.
Connect a communication line by means of a corresponding terminal. Corresponding data are stated on
the instrument label, regarding the selected communication. Connector terminals are marked on the
label on the upper side of the instrument. More detailed information on communication is given in
chapter Communication.
