For vertical use of the rack enclosures M72R8 and
M72S8 an optional pair of tower feet is available (Figure
7).
For later attachment of the tower feet remove the left two
plastic caps from the front side of the rack enclosure and
unscrew the aluminum cover (Figure 10). Slide out the
two plastic strips and slide in the two tower feet instead.
11.2. USB Interface
The M72R1 and M72S1 modules are configured within the rack enclosures M72R8 or M72S8
via a USB interface.
The first time you connect the rack casing to a PC you will be asked to install the device driver.
The driver data file “MMF_VCP.zip” is located on the internet site
http://www.mmf.de/software_download.htm#m72
.
Unzip and save both of the enclosed files to a directory on your computer. This directory will
need to be entered when windows asks you for the device driver. The provided driver is signed
and can run in Windows XP, Vista, 7, 8 and 10.
The computer will install a virtual COM port which runs in CDC mode. The advantage of the
virtual COM port is that the modules can be controlled via ASCII commands in an uncompli -
cated manner. Several rack enclosures can be connected to a PC at once, however, each rack en-
closure requires its own USB port.
The addressing is carried our via a switch at the back of the rack enclosures. The configuration
is hexadecimal from 0 to F.
