What you need

A switch or router in the booth with a free port, or a free LINK socket on the DJM.
A network cable to FOH. Up to 100 m is fine for Ethernet; use a good Cat5e/Cat6 cable.
A laptop with LJ Link (and a USB network adapter if it has no socket).
Access to the grandMA2 show: Telnet on, a user with rights.

Booth: check that all players and the DJM are on the switch and have different player numbers.
Cable to FOH: plug the long cable into the switch and the laptop. Switch Wi-Fi off on the laptop.
Search: start LJ Link, Search automatically. All players and the mixer appear.
Desk in the network: plug the grandMA2 into the same switch, or use its own network (two networks). Check that addresses fit (basics).
Desk: Setup → Console → Global Settings → Telnet Login Enabled. Effects that should follow the tempo on Speed 16 (BPM).
LJ Link: LINK → grandMA2 → Search for the desk → click it → user/password → Save → Send test. The master jumps to 120.
SEND BPM on Auto: the tempo follows the master deck that is on air.

Checklist before the doors open

Every player shows a track and a waveform.
The red LIVE frame follows the channel that is up.
Green SEND BPM sits on the right deck, the master on the desk follows a tempo change.
Laptop on mains power, sleep mode off.

A DJ changeover with new players: they are added by themselves; old ones disappear after a few seconds.
Tempo jumps between two decks (both master)? Fix SEND BPM to one deck for this moment.
Want your effects to follow only in parts of the set? Leave the link on and switch the effect to another speed master on the desk.
