As per the following page, T3 devices should use 47 ohm resistors on MIDI Out. How are these values calculated? What amount of loop current will those resistors provide?

I have a customer that is suggesting that my MIDI out circuit is causing his CME WIDI Master dongle to fail, and I'm trying to investigate if there's any way my MIDI Out circuit could be the culprit.
Also, in the unlikely event that pin 4 gets shorted to ground, would that sink enough current to kill the TX pin? Are we advised to to use a buffer?
