Connecting the USM to an HID device

All interfaces used on the USM (USB, RS232, RS422 and RS485) can be connected to an HID device.
The prerequisite is a software wedge application on the PC / host using which the interface data can
be converted into USB-HID. Software wedge applications are not supplied by BARTEC, but they are
available on the market (e.g. T-Wedge).

Connecting the USM to a PLC

All used interfaces of the USM (USB, RS232, RS422 and RS485) can be connected to a PLC.
There are a number of different manufacturers for SPS/PLC. The connection of a hand-held scanner
depends on the availability of an interface to the SPS/PLC and the ability of the SPS/PLC to process
the incoming data. The SPS/PLC must support the open ASCII protocol.
There is no compatibility list.
The following must be observed when connecting to a PLC:
What interfaces are available on the SPS/PLC? The USM supports the following interfaces.
-
USB-SPP (virtual serial interface)
-
RS232
-
RS422
-
RS485
-
The SPS/PLC supports the open ASCII protocol.
What interface parameters are set on the SPS/PLC?
-
All interconnected components must be set to the same parameters. Otherwise a
communication cannot function correctly or not at all.
Baud Rate
-
parity
-
Stop Bit
-
Data Bit
-
Hardware/Software Handshaking
-
How the data is processed at the SPS/PLC and what has to be set at the scanner is the responsibility
of the plant operator.
For example, a serial interface has no intelligence of its own and cannot process incoming data
independently. This means that the controller must monitor the serial interface and process incoming
data (read/write routine).
An example project for scanner connection to a Siemens Simatic-S7 SPS/PLC is available on the
BARTEC Support Download page.
