Software
The Color Controller C-80 diagnostics software is used for testing both proprietary
Creo hardware (FusionRA) and standard off-the-shelf hardware.
There is JOIND (Java Over the Internet Diagnostics)—an Color Controller C-80
client/server diagnostic controller—that runs locally or over a TCP/IP connection.
JOIND runs under a Windows platform (NT/98/2000/XP) and enables local
diagnostic testing of Color Controller C-80 products with user level support.
