Chengdu Ebyte Electronic Technology Co,;Ltd E90-DTU (170L30) user manualCopyright ©2012–2019，Chengdu Ebyte Electronic Technology Co,;Ltd 13★ Note:1.programming can only be carried on in a specific mode (see above), if fails, please confirm the work mode.2.If there’s no complicated programming, opening the E90-DTU 数传电台配置软件 (E90-DTU parameter configurationapplication) to modify parameters.7.2. Parameter setting instructionParameter DescriptionBaud rate The serial port baud rate of a wireless data station at work，1200bps～115200bps。Odd-evencheck Support 8N1:no check ；8E1:even-check；8O1:odd-check； Both are 8-bit data bits and 1-bit stop bits.Air data rate（bps）Wireless communication rate, also known as air baud rate air rate high, data transmission speed, transmissionof the same data time delay is small, but the transmission distance will become shorter.TransmittingpowerIn order to ensure the working efficiency, it is recommended to use the maximum power. If the transmittedpower is reduced, the communication distance will become shorter and the required current will be reducedFEC The lost or interfered data can be partially corrected by complex encoding, which can improve the equivalentreceiving sensitivity by about 3dBm. Turning off this function can reduce the communication delay.TransmissionmodeFixed length transmission: automatic subcontracting in traditional wireless transmission mode, with amaximum of 77 bytes per packet.Continuous transmission: unlimited packet length, supporting wireless continuous transmission.Wake UpTimeThere is no direct relationship with the communication delay. If the customer needs low-power applications,this option shall be adjusted as required. In the power-saving mode, the longer the wake-up time, the lower thepower consumption of the receiving end, and the greater the communication delay. |
