26 / 36 www.waveshare.com
Cooperate with Vircom and 4.99 (SN7044)/5.92 (SN2043) firmware to realize
timing configuration. Copy the following character string "68 99 99 99 99 99 99 68 08 06
TIME[25...30] CRC[3] 16" to the serial port for simultaneous output command when sending;
copy "TIME[0]" to the output condition .
Note that you must set at least one JSON data to be sent in order to implement timing
and delivery. In addition, the time service can only be done after the TCP connection is
established, because the time service occurs when the network is sent. If the TCP is not
established, it will not be sent, and there is no time service.
Figure 27 645 timing configuration
The "TIME[0]" here is optional. If it is filled in, the time service will be sent after the
device obtains the effective time. If you do not fill in, the time service will be sent under any
circumstances. If the time service is incorrect, it will cause problems.
4. JSON TO MODBUS RTU
JSON to Modbus RTU supports 05/06/16 command. If you need to use the 15 command
to set multiple coils, please use the 05 command multiple times.
According to the length of the number of bytes, the system will automatically select the
06 or 16 command to send. Here are examples of setting coils and setting registers.
