1734-232ASC without terminaison character

[tino63 0]

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
