Functions descriptions:
16 default channels are set before shipping. Channel 0 -7 for DMR channel, channel 8-15 are analog Walkie Talkie. A rotary switch is used to change the channels. And Pin7 –10 output the channel status.
1) Parameters setting
Both Standard mini-USB interface and serial UART interface are used to configure the parameter. Either of them can be used. And we provide PC software which is easy to use to configure all the necessary parameters. Below is the typical connection diagram.
2) Serial Communication Protocol
All the parameters of DMR818 can be configured using the Serial Communication Protocol.
MSB for the command.
