Xl Iap Online Firmware Upgrade - Ebyte E90-DTU Manual

Chengdu Ebyte Electronic Technology Co.,Ltd.
 In the Configuration Upper, the module address, frequency channel, network ID, and key are in decimal display
mode, where each parameter takes a range of values:
Network address: 0-65535
Frequency channel: 0-83
Network ID: 0-255
Key: 0-65535

Users need to pay special attention when using the upper computer to configure the relay mode, because in
the upper computer, each parameter is in decimal display mode, so the module address and network ID need
to be filled in by converting the system. For example, if the network ID inputted by transmitter A is 02,
and the network ID inputted by receiver B is 10, then when relay R sets the module address, it will convert
the hexadecimal value 0X020A to the decimal value 522 as the module address filled by relay R. That is to
say, at this time, relay R needs to fill in the module address. That is, the module address value to be filled
in by relay R is 522.
