Network Warning Message
The Master cradle can transmit warning messages to the Host regarding some network
errors.
/*Slave xxxx not responding*/:
when the Master can no longer commu-
nicate with the specified Slave previously identified at start up.
/*Frame out of sequence for terminal xxxx*/:
if a reader is send-
ing data packets out of sequence. This can happen
if there are transmission problems
on the network (either connection or communication), or if the reader has correctly
transmitted data to a device not on the network (reader configuration error).
The message is sent in the following format:
"Message" CR LF
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 page 165.
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 "Header/Terminator Selection" on page 154 and "Define Special Key Sequence" on page 155.
