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.

4 Description
4.1 System Overview
4.1.1 Modular Draco vario System
The Draco vario chassis are compatible with all available Draco vario extender modules and add-on modules
(CPU Unit and CON Unit), CWDM modules, repeaters, fan modules, and SNMP modules for standalone or rack-
mounted configuration. The flexible, modular system allows custom integration of equipment to meet specific
installation requirements. Chassis are available in sizes for 2, 4, 6 and 21 individual modules.
Therefore, please first select a chassis, then select one or more extender module(s), then select one or more add-on
module(s) if required.
The Draco System Designer, available on the IHSE website at https://dsd.ihse.com, will help you with system
configuration.
For more information, please refer to
the manual 474
-BODY.
Described in this manual. For more information,
please refer to the
respective extender module
manual.
4.1.2 System Structure and Terms
A KVM pair consists of 2 KVM extender modules, each with at least one CPU extender module and at least one CON
extender module. The various extender modules are installed respectively in a Draco vario chassis (2-slot, 4-slot, 6-
slot, or 21-slot) on the CPU side (CPU Unit) and console side (CON Unit). With 2-slot, 4-slot and 6-slot chassis add-
on modules are placed above an extender, with 21-slot chassis, add-on modules are placed to the right of an
extender module. An add-on module will not work if it is mounted above an empty slot.
The assignment of add-on module and USB 2.0 stand-alone modules can be recognized by the article number:
• Add-on module/USB 2.0 stand-alone module for the CPU Unit: L4XX (L = Local)
• Add-on module/USB 2.0 stand-alone module for the CON Unit: R4XX (R = Remote)
474-Add-on Modules Description
13
An add-on module can contain up to 2 independent function parts (part A and B), one on the left and one on the right,
see Fig. 1.

4.1.3 Embedded Signals
If optional add-on modules are used, signals such as e.g., audio (analog, serial, digital or symmetrical) or USB 2.0
are transferred to the underlying extender module and embedded as well as transmitted via the link connection to the
CON Unit. The embedded signals are extracted in the CON Unit, transferred to the add-on module above and output
there separately.

* Extender modules of HDMI 1.3 Serie 481/491 and DP 1.1 Serie 483/493 support 5.1 channel digital audio whereas
extender modules of HDMI 2.0 Serie 495 and DP 1.2 Serie 490 only support 2-channels
Requires an audio add-on module on the CPU Unit or the CON Unit
True embedded audio
Connection is representing audio content only
Analog audio add-on modules are not necessarily audio compatible to each other since they use difference protocols.
The following table lists the audio compatibility (X) and non-audio compatibility (-) for analog audio add-on modules:
