7.1. Packing mechanism
Serial to Network Packet Delimiter: Packet delimiter is a way of packing data in the serial communication. It is designed to keep
packets intact. USR-M100 provides two types of delimiter: Time Delimiter, Maximum Bytes Delimiter. Note that the following
delimiters (time, length) when they are selected are programmed in the OR logic. Meaning that if any of the two conditions were met,
the device would transmit the serial data in its buffer over the network.
Fig. 87 Data packing mechanism
Packet time: USR-M100 will transmit the serial data in its buffer when the specified time interval has reached and no more serial data
comes in. The default value is calculated automatically based on the baud rate. If the automatic value results in chopped data, the
timeout could be increased manually by specifying a larger value in the text box above. Note that the maximum interval is 255
milliseconds. This option is disabled by default.
