Output short on ADuM6400

I am looking at producing a cable tester. So,effectively a cable loop up to 3 metres which may or may not have cable faults.

I was planning on using  Isolators such as the AduM6400 and ADuM6404 to protect a microcontroller from output shorts . The idea being to test cables and wiring looms by reading the sent signals back at the micro for continuity (signal received on correct pin) short circuit ( signal received on 2 pins ) and open circuit (no signal received).

My question is that I know nothing of the output of the ADuM6400 and how it can handle shorted output pins. Perhaps I should be using  buffers to protect the isolators outputs.
