1.4 Intended Use
Add-on Modules
Add-on modules are only intended for use in conjunction with extender modules and for installation in 474-BODY
chassis. Add-on modules are used to embed and de-embed signals and data, e.g., audio or USB HID signals or
USB 2.0 data. All signals and data are transferred via interconnection between extender modules (CPU Units and
CON Units).
USB 2.0 Stand-alone Modules
USB 2.0 stand-alone modules are used to increase the distance between sources and associated consoles. The
transmission range of USB 2.0 data can be extended using Cat X cables or fiber optic cables.
USB 2.0 stand-alone modules with Cat X connections are unsuitable for connection between buildings. Use a fiber
optic-based extender module instead.
USB 2.0 stand-alone modules with fiber connections can also be used with applications in environments which are
subject to electromagnetic interference.
Fan Cartridge Module
The fan cartridge module is used for ventilation of 474-BODY chassis.
