Firmware Version IBBxxxxx.S2
(xxxxx denotes version, e.g. V0102 = version 1.02 or higher)
Communication parameters:
Baudrate 115200
8 databits, 1 stopbit, no parity bit
Protocol:
Language: ANSI X3.28 standard
Type: select type using SetupRFS program
Return messages:
host can send return messages to RF devices
Description:
With this protocol, the host must always send a response to the RFS6000 when it receives a
message from the RF device. The response may contain useful data relating to the received
message. The host is only allowed to send a message in response to a message from the RF
device.*
To be able to address a specific RF device in the network, a 3-byte header precedes the
message. The length of a message (including the header) is variable, but never exceeds 256
bytes. A message looks like this:
For transmission and response the same protocol is used, however the roles of sender and
receiver are reversed. The 3 byte header of the response message must be identical to that of the
corresponding received message.
*
Note: If the application requires special messages to be sent to the RF device that are not initiated by an action of the user,
the RF device could be programmed to regularly send empty messages to ask for these messages.
