Figure 13 Serial port basic parameters
2.3.2.VCOM Application
Figure 14 VCOM application
User can download VCOM software from http://www.usriot.com/usr-vcom-virtual-serial-software/.
Through this software user can set up connection between 410s and virtual serial to solve the problem that
traditional equipment PC software used in serial port communication way.
2.3.3.Flow Control
410s supports hardware flow control way ( RTS/CTS, only take effect in RS232 mode ) and software flow control
way Xon/Xoff.
2.3.4.Serial package methods
For network speed is faster than serial. Module will put serial data in buffer before sending it to network. The
data will be sent to network side as data package. There are 2 ways to end the package and send package to
network side - Time Trigger Mode and Length Trigger Mode.
410s serial package time: Default is 4 bytes sending time, range from 0 to 255.
410s serial package length: Default is 1460 bytes, range from 0 to 1460.
2.3.5.Baud rate synchronization
When module works with USR devices or software, serial parameters will change dynamically according to
network protocol. User can modify serial parameters by sending data conformed to specific protocol via network.
It is temporary, after resetting DTU, the parameters will back to original parameters.
