Awaken from Air, you can transmit some useless data firstly.
HXJZ-877 parameters setting
HXJZ-877 have one interface of TTL、RS232、RS485, You should say clearly which interface you need
when place an order.
HXJZ-877 main parameters: COM baud rate and verify ，RF baud rate, Channel and frequency.
You can change these parameters by our RF Module soft. Wh en RF baud rate is faster than COM baud
rate，One frame Can transmit limitless data. When RF baud rate is not faster than COM baud rate ，One frame
Can transmit 255 bytes most. You can set the rate according your need.
The general Power supply is 5V DC.
