Things You'll Need
Instructions
Big PS2
Connect the iLink cable into the PS2's connector labeled "S400."
Turn on the systems and place the same game into both systems.
Select multiplayer, then "LAN." The systems will "see" each other automatically, allowing players to play on separate TVs.
Slim PS2
Connect a Cat 5 crossover cable into the ethernet ports of both PS2s. A Cat 5 crossover cable is a special version of an ethernet cable designed for system links.
Place the PS2 network start-up disc into the first PS2. Go to "Manual Settings." Enter "10.10.100.1" for the IP Address, "255.255.255.0" for the Netmask, "255.255.255.0" for the Default Router Address, "216.99.193.19" for the Primary DNS Address and "216.99.193.2" for the Secondary DNS Address. Save the options.
Put the start-up disc into the second PS2. Go into "Manual Settings" and enter the same settings as the first PS2, but change the IP Address to "10.10.100.2." Save the options.
Place the same game into both systems. Go to the game's multiplayer LAN options, and the game will recognize the other system.
