RT38B01 FAQ
Customer :
Hello.
I just bought 5 pieces of RT38B01 to use with my PTZ Cameras. I would you to confirm that my connection is correct since so far there is no transmission.
TRANSMISSION
1. PTZ Software Control Software
2. Waveshare RS485-USB Converter
3. RT38B01 (terminal + and -
RECEIVE
4. RT38B01 (terminal + and -)
5. PTZ Camera
The cameras are not responding. Could it be that my connection is wrong?
Could it be that the transceivers need power through a third cable?
Eletechsup :
The vin gnd interface is not connected to the power supply.
The following debugging is also required:
1 Use the serial port assistant to test the direct transmission and reception of the two modules.
2 Make sure the serial port parameters of the bottom device are 9600 n 8 1
