4.1.2 Modular Draco vario System
Draco vario chassis allow individual Draco vario series extender modules and add-on modules to be combined in
standalone or rack mounted configuration. The flexible, modular system allows customized integration of devices to
meet specific installation requirements. Chassis are available in sizes to accommodate 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

4.1.3 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 the extenders or add-on modules can be recognized by the article number:
•Extender module or add-on module for the CPU Unit: L4XX (L = Local)
•Extender module or add-on module for the CON Unit: R4XX (R = Remote)
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. 2.

4.1.4 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.
Example with optional Add-on Module L-/R474-BAE

1) Compatibility is based on video/USB HID signal only, not on the embedded signals like audio or USB 2.0.
2) Compatible up to the maximum specified resolution of the console.
No image is displayed when a Single Link CON Unit (e.g., R482-B2HC with 1080p monitor) is switched to a
Dual Link CPU Unit (e.g., L482-BDHC with a 4k30 video signal) unless the configuration is set up accordingly.
3) If using CPU Unit and CON Unit with different video signals (e.g., a DP 1.1 CON Unit with a HDMI CPU Unit),
transmitting the EDID to the CPU Unit will result in an error.

4.2.2 Interconnection Compatibility
Extender modules are available in the following connection versions. The type of interconnection of extenders can be
recognized by the article number:
•Interconnection (1.25 Gbit/s = "1G") via Cat X cable ("C")
•Interconnection (1.25 Gbit/s = "1G") via single-mode fiber cable ("S")
•High speed interconnection (3.125 Gbit/s = 3G) via single-mode fiber cable ("X")
Fiber devices can be used with Multi-mode and Single-mode cables (see chapter 13.2.2, page 77).

A special card (bridge card) is available to be used with the matrix Draco tera enterprise and Draco tera flex to
connect up to 8 CPU Units with 1G transmission speed (Cat X or fiber version). The transmission speed will be
increased within the bridge card from 1G to 3G. The signals are transmitted to the backplane of the matrix and can
be output to up to 8 CON Units, connected to the matrix.
This function is only available in one direction.

4.3.4 Supplementary with Extended Function for Extender Modules
SNMP Module
To monitor all function- and safety-critical components of extender modules and add-on modules of a chassis, an
SNMP module installed in the same chassis can be used.
The SNMP module can be used to query the status of the extender modules, configure extender module settings,
and query and update the firmware of the extender modules and add-on modules. For more information, please refer
to the SNMP manual.
Part number Description
474-SNMPV3 SNMP module for sliding-in into slot 5 of the chassis 474-BODY6BP/474-BODY6BP-S
and 474-BODY6BPF/474-BODY6BPF-S and into slot 21 of the chassis
474-BODY21/4U(-R1) and 474-BODY21/4UR(-R1).
The transmission of the traps is encrypted (SNMP v3).
U-Switch Module
Extender modules can be combined with a U-Switch module that can seamlessly control multiple sources as one
source using just a single USB HID set (keyboard and mouse), while the video outputs of the sources are directly
connected to the monitors. For more information, please refer to the Draco U-Switch manual.
