5.4.

U2S

U2S mode allows for UDP communication.

In UDP mode, data are transmitted in blocks, which require dividing data coming to the

serial port into blocks before transmitting data. A procedure for dividing data into

blocks is as follows:

If data of pre-specified bytes [Water Mark] comes to the serial port of the EZL-410 or if

a specified period of time [Timeout] elapses after first data reception, all data received

for the same period is recognized as one block which is then transmitted to the

UDP. The [Timeout] unit is 10ms. If [Timeout] is set to 2, the time period is between

20ms and 30ms.

Since UDP communication does not require a connection procedure, the user can make

1-to-N communication via broadcast.

√

SSL protocol cannot be used in U2S, because SSL works over TCP.
