NTP standard time service module; Time service module

  Product introduction
 
  SNTP protocol (simple network time protocol rfc1769) is a protocol that provides time information to devices in the network
It is usually used in LAN
Through SNTP protocol, devices on the network can obtain very accurate
The exact time

 
  At present, many time servers are based on serial port
In order to meet the requirements of networking, Xi'an Weizhou has developed SNTP module
Receive accurate time information from the serial port, and then provide accurate time information to network devices
Room

Generally, SNTP module can be directly connected with GPS module to directly analyze GPS output time information
In addition, Xi'an Weizhou can make personalized modifications according to the customer's serial port protocol
