TS-7250-V2 unable to see /dev/ttyS1 and /dev/ttyS2

Hello community:


I have bought the 

TS-7250-V2


I want to use the top 2 expansion rs-232 9pin port 


however I can't see a /dev/ttyS1 or /dev/ttyS2


I don't know what is missing since I got the product preinstalled for my by embeddedarms and didn't touch the inside since it was bought with the TS-ENC720-7200-2ETH enclosure.


I need these 2 interface to connect some sensors together and I can't use other interface as it loose time sync

Good evening Wen Bo Ma,


The ports ttyS1 and ttyS2 do not exist on the TS-7250-V2.  You will want to read the product manual in a few sections to define which ports you are looking for in better detail.  Start with these:
