====TCP (ASCII/Binary) modes====
====TCP (ASCII/Binary) modes====
In TCP ASCII/Binary mode all data received from the external device is sent directly to the server. Data is encapsulated in codec 12 format. TCP Binary Mode has a delay of 30 ms, if no data is received for 30 ms, data is sent to the server. TCP ASCII mode waits for the End of Line (EOL) character (0x0D0A, \r\n, <CR><LF>) to pack data and send it to the server.
TCP ASCII Buffered and TCP Binary Buffered modes are used to collect data from RS232 and save it in the buffer if there is no link with the server and data cannot be sent immediately. When the link is established and there is data to transmit, then RS232 data from the buffer is transmitted after all records are sent. Data is sent in codec 13 protocol. Note. That in TCP ASCII and TCP Binary modes device sends data from the external device only to the main server. In Buffered modes – to both main and backup/duplicate servers. Message timestamp: The message Timestamp parameter is used to determine if it is necessary to include a timestamp in the RS232 TCP packet when sending to the server. If the parameter is enabled, then Codec 13 is used for data sending. Otherwise, Codec 12 is used.
