What to do if LAI Games Arcade Game Machines won't link and show error Er4?
- Mmatthew24Jul 31, 2025
If your LAI Games Arcade Game Machines display error code Er4 and won't link, ensure all link cables are tightly connected, running in a continuous loop from the 'IN' of one machine to the 'OUT' of the next, following the provided diagrams. Also, verify that only the Overhead Jackpot Display is set as the 'MASTER MACHINE,' and all other game machines are configured as 'SLAVE MACHINES' using program adjustment P01. If Er4 appears on multiple machines, set the additional machines to 'SLAVE'.
