Ascend Single Phase Charger Operation Manual
7.7.5.3. Network Time Protocol
The Network Time Protocol (NTP) compatibility allows the Charger to synchronize the system time with
a NTP server on the network. The time will be synchronized once an hour. This feature can be enabled
on the User Interface Setup -> Network Settings -> NTP.
7.7.5.4. Modbus RTU Setup
Serial Modbus communications over RS-485 using RTU mode is optional. Modbus communications
settings may be configured in Setup -> Modbus Settings.
The Modbus Settings Screen allows the user to configure the address, baud rate, parity, and RTU
address used for Modbus RTU communication.
Modbus RTU registers can be read over the RS-485 connection. A minimum delay of 2 seconds is
required between polls. The Modbus registers, which are read only, can be found in Appendix A: for
Modbus mapping.
