Don't count the time establishing a connection towards a command timeout.

Browse source 
Note: connection timeouts are also dealt with. They're now (cleanly)
separated: connect- and command-timeouts.

If the pump's display is one due to the user interacting with the pump
directly, the pump needs a display timeout before being ready for an
incoming connection. What I'm trying to say is, it might take some time,
maybe up to 30s to establish a connection in that cause and can thus
easily create a false timeout error.
