- Page 2 <10ms. 11. Multi-channel and speed ATC-875 provides various baud rate 1200, 2400, 4800, 9600, 19200 and 38400bps. The wireless transmission speed and the connection baud rate are proportional, to satisfy the customer’s equipment. 12. High speed wireless communication and big data buffer When the RF baud rate is bigger than the COM baud rate, it can transmit unlimited data at one time, and when the RF baud rate is smaller than or was equal to the COM baud rate, may transmit 512 bytes data.

- Page 5 ATC-875 Mini Power Wireless Module User’s Manual A. Connect ATC-875 with the Computer and power, and choose the COM ports. B. Search the radio, when search it successfully (the software will clew it), then we can read and write the parameters.
- Page 6 ATC-875 Mini Power Wireless Module User’s Manual Note: if don’t connect the NO. 1 pin, then ATC-875 is in Normal work status. To change the module from awaken state to dormant state, only need to change the SLE low level to high level, the MCU will become dormant state in 1ms.
- Page 7 ATC-875 Mini Power Wireless Module User’s Manual 7. Interoperable models ATC-875 can communicate with all the JZ87 series models. Please kindly pay attention to the following points when transmitting: A. Select all the modules the same channels. B. All the modules with the same RF baud rate.
