hello, i need to communicate with a faig rfid system .

My configuration:

CLX L55 + CNB/E ->1734 ACNR / 1734 232ASC / 1734 IB4

My problem:

the feig system sends datas with differents size which depends of the command (read, write, inventory..)
without End character like 'CR' . At the end of datas, there is only the CRC16 (2 bytes) (always different) and that's all.

But i've read in the manual of 1734-232asc that we can use two mode :

1)the maximum size of the input table (for example size :24) or
2)the end character CR to send datas in buffer to plc

My question: do you know how to receive datas without end of string delimiter.

best regards

tino
