# BIO2 sub IO turntable bypass cable
|
|
If you upgraded a C02/IO2 wired cabinet, the turntables are connected to the
|
|
sub IO via a serial line that goes to another sub IO behind the front panel
|
|
next to the 16seg display. This introduces additional latency as the input
|
|
data needs to pass through multiple systems/PCBs until it reaches the game.
|
|
|
|
This can be reduced by using a so-called "bypass" cable, that connects the
|
|
turntables directly to the BIO2 sub IO board reducing latency significantly.
|
|
|
|
This cable could be ordered with any IIDX upgrade kit including the BIO sub IO
|
|
board but can also be easily created from scratch.
