4.1.18 Hardware Flow Control RTS/CTS
410S support serial RTS/CTS Hardware flow control function. It is disabled by default. Don’t enable it if
device doesn't support Hardware flow control .
4.1.19 Reload
Cut off power firstly.
Press “reload” and supply power. Then keep pressing reload for 5 seconds.

4.1.20 Flow Calculation
When 410S receive data from network and send to serial, user need to control the flow because of limit
of serial speed. Otherwise, serial data will spill.
For example, network send data m bytes every n seconds.
m bytes should be transmitted with n seconds. And the transmit time is
If n>2T, the data won’t spill and 410S can work well. If baud rate is less than 9600, should keep n>T.
4.1.21 Synchronous baud rate (RFC2217)
For encryption during data transmission, devices change data bytes, baud rate, parity and so on. 410S
support revise serial parameter accordingly.
Synchronous baud rate is named RFC2217. USR Similar RFC2217 make adjustments on the basis of
