Hi, I have a problem on enable RS485 on Xbee-Pro XSC S3B 900Mhz.
I don't have this problem on Xbee 2.4 GHz.
In X-CTU, Modem Configuration Page is
Function set: XBee-Pro XSC (S3B) 9600 920 MHz
Version: I tried both 3209 and 320C, not work
In Serial Interfaceing
CS-DO2 configuration : 3-RS485 TX enable high
My problem is PIN12 is always high after power on. Therefore, Xbee can not receive Data via RS485 communication from computer but it can get data from another Xbee.
PIN12 will be low after it get data from another XBee. And it works perfect after that.
After power on I did not send any data why PIN12 always high.
Please help thank you
