Commenting on Ulster's first away trip of this season's Heineken Cup, McLaughlin said: "We have shown we can win away from home in the Magners League and now it's time for a Heineken Cup away win.
"Edinburgh will be up for the challenge at home and we will have to step it up another level again.
"They know their Heineken Cup hopes will be severely hurt if they lose their second game, so they will be going out to stop a run of three straight defeats when they face us.
"We know they are going to come at us hard and we are under no illusions about the massive task ahead of us.
"If we play to the best of our capability it is a game we are capable of winning, and after the win against Bath, we cannot afford to underachieve at Murrayfield."
"We're working hard and now it's all starting to come together."
