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
