12.6.1.1 Wireless hand-held scanners on the MA 238
i
All wireless hand-held scanners and mobile combi devices available in the Leuze product line can be used
with the corresponding connection cable via the base station.
A 230VAC connection (socket) is usually necessary for the charging station. Here, a data connection of
the charging station is established with the MA 238
i
. The corresponding cable is to be selected for the
respective hand-held scanner and ordered separately. Connect this cable to the 9-pin Sub
-
D cable
(KB JST
-
HS
-
300, part no. 50113397), which is connected to the MA 238
i
. This cable must also be ordered
separately.
In this example, triggering occurs by means of a trigger button on the hand-held scanner.
The following codes for configuring the devices are necessary for these devices as well.
12.6.2 Specific features in the operation of an RFM/RFI
When using the MA 238
i
in connection with an RFID device, we recommend a data width of at least 24
bytes to be able to transmit information to or from the reader in a telegram.
Shown here is a sample telegram for a write command in combination with an RFID device.
Example:
NOTE
When using third-party devices, check the pin assignment and interface settings without fail and
adjust them if necessary.
NOTE
Also note that all characters which are sent to a transponder are hex-encoded ASCII characters.
Each of these (hexadecimal) characters is, in turn, to be handled as an individual ASCII charac
-
ter and converted to hexadecimal format for transmission via the fieldbus.
