Narrative:

We had a passenger issue in the back of the aircraft; and requested direct to ZZZ. We were given priority handling from ATC. We only had one FMC that had ACARS capability. While I was trying to communicate with our company via ACARS; my first officer; who was flying the aircraft; was unable to get the weather for our arrival; due to a single ACARS setup.I think it could be a continual safety issue; with only a single ACARS setup; in our aircraft when you are in a time sensitive situation; and severely limited to needed information for the safety of the flight. Only one of us could use ACARS at a time.
