Serial Port Issues on RB450

Hello,

I have several RB450s that I use for SCADA on pole mounted RTUs. The RTUs are polled for infomation from a server 24/7 consistently.
My problem is that I have to reboot each RB450 every morning as the connection is dropped, and I have no idea why it drops out. I am wondering if the serial port firmware/chip cannot handle sending data all day every day?

Here is my configuration for the serial port:

system console disable 0
port set serial0 baud-rate=9600 data-bits=8 parity=none stop-bits=1
port remote-access add port=serial0 protocol=raw tcp-port=50000


My only other configuration is changing the ip address. Thats it…


So any ideas why my connection drops out daily?
Is my configuration ok?
:confused:
