Packet delimiter is a way of controlling the number of packets in a serial communication. It is designed to
keep packets intack. SE5002 provides two ways in parameter setting: 1. Packet delimiter timer and 2 .
Character pattern terminator . By default, packet delimiter timer is 1 ms. The range of packet delimiter timer
is 0 to 30,000 msec, as shown in Fig. 20. If “character pattern is selected, for a data stream ended with
“0x0a04”, then the entire data buffer of the serial device is transmitted.
