The message is sent in the following format:

"Message" CR LF

5.3.3 Reception Warning Message

The Master cradle can transmit warning messages to the Host regarding wrong

reception of data. Example:

/*Two-Ways Out of Sequence!(.....)*/

This message is transmitted to the Host by the Master cradle when the

Master cradle receives a closing string from the Host for a Two-way tx

communication, but this was either not open or already closed, therefore the

data will be lost. See section 5.9.4.

5.3.4 Master Header/Terminator Selection

In addition to the standard header/terminator selection, the Master cradle can add its

own header/terminator to the entire message sent to the Host.

In the STAR-System™ network headers and terminators for all RF Devices are

disabled by default.

The Master header and terminator default values are as follows depending on the

interface selection towards the Host:

RS-232: no header, terminator CR-LF

WEDGE: no header, terminator ENTER

See sections 5.4.1 and

5.4.2.

5.4 DATA FORMAT

For an overview of Message Formatting see Chapter 6.

5.4.1 Header/Terminator Selection

The header/terminator selection is not effected by the reading of the restore default

code. In fact, header and terminator default values depend on the interface selection:

RS-232: no header, terminator CR-LF

WEDGE: no header, terminator ENTER
