Operating Instructions

commands to be transmitted in the wireless network do not reach the transponder or reach it
incompletely, no event message is generated in this case.
If an RPC call sets a field form to a value that is already set, an event message is sent
immediately. This happens during or very shortly after the RPC call. Event messages are sent
when a situation is reached.
If a field content still to be transmitted is overwritten again before the previous value could be
sent to the transponder, only the value set last is transmitted to the transponder. In this case,
only the writing of the last value is acknowledged by an event message.
The transmission of background images, fonts and theme files is given higher priority and
temporarily interrupts the transmission of text content.
3.3 RPC calls
Parameters of the RPC calls
The following parameters can be used for RPC calls via the programming interface:
Parameter Description
TransponderID 48-bit ID according to IEEE EUI-48
The network address in decimal notation contains the transponder ID:
17:b4:1a:bb:cc:e2
17:b4:10:00:00:07
17:b4:11:23:45:67
180079842

19088743
ThemeID The number of the displayed theme
The value range depends on the type and version of the transponder.
FieldID The number of the text field
The value range depends on the type and version of the transponder.
Text Permitted characters: all printable ASCII characters and German umlauts
Result Sends the return value
