2 Installation and Operation
System information2.1
2.1.1 Required tools
No tools are required for a standard connection or DIN rail
mounting. However, a module protection is recommended for
standard connections.
For a secure mounting on the optional module holder from
E.E.P.D. we recommend following tools:
- Module holder: cross-headed screwdriver
Further required tools depend on mounting type and place.
2.1.2 External documents
Please note also external mounting and user manuals.
2.1.3 Technical support
For technical information about hardware or software please
contact ‘[email protected]’.

2.1.4 Installation and connection
regulations
Please follow all safety instructions at the
place of installation.
Please ensure that during installation no
voltage is applied.
Please ensure that during mechanical
installation no cables are connected.
2.1.5 Scope of supply
Please check before installation that all required parts are
complete:
- 1x IM232/485 USB module
- 1x cross-headed screw
- Hardware Reference Manual
- Driver CD-ROM
2.1.6 System characteristics – usage
The RS-232/485 module allows a system extension to a
D-SUB-9 connector via USB port. Especially in industrial
environments, many technical devices use this RS-232/485
interface. Via the USB module, serial connections to service
and configuration connections of various end devices that
require an RS-232/485 connection can be established. Thus
telephone systems, control units, routers, POS terminals,
switches, storage systems as well as microcontrollers can be
operated and programmed with modern computers.

Mounting solutions2.2
2.2.1 USB port installation
If the installation site permits, the USB adapter module can be
plugged into any standard USB 3.0/2.0/1.1 Type A socket.
To avoid mechanical stress on interfaces,
we recommend a safe module holder.
The full range of functions depends on the
respective USB port.

2.2.2 DIN rail mounting
The USB adapter module is designed for mounting on a TS35
mounting rail (DIN rail). The following procedure is
recommended for insertion and removal.
Insertion:
Hang the module on the clip lock in the mounting rail, push it in
the direction of the USB plug and snap it into the rail.

2.2.3 Mounting on E.E.P.D. module carrier
The USB module is particularly suitable for connection to a
TB-H USB hub, as well as to a TB-M from E.E.P.D..
The mounting profile offers space for seven USB modules, to
mount them easily and stable. Insert the USB module into the
guide of the respective slot and push it back to the stop. Secure
the module with the enclosed screw.

Initial Operation2.3
Commissioning is easy. As soon as the USB module is
connected to the USB connector of your system for the first
time, your operating system usually automatically searches and
installs the necessary drivers. However, you can also install /
update these from the ‘Drivers’ folder on the supplied driver CD-
ROM.
For your information, please also read the README file
provided on the CD-ROM.
The wiring and operation of connected systems of external
companies can be found in their documentation.
The dialog with the module takes place by means of simple
commands in ASCII code and can usually be realized from any
application, among others with a terminal program, by
accessing the serial interfaces without special effort. To set up a
virtual serial interface, it may be necessary to install the
appropriate driver for the respective operating system. These
are on the supplied CD-ROM.
