4.1 Intended Use
Extender modules are used to increase the distance between sources (computer, CPU) and associated
consoles (monitor, keyboard, mouse, and other peripherals). The signals can be extended using Cat X
interconnect cables or fiber optic interconnect cables.
Extender modules with Cat X Interface:
Extender modules with Cat X connections are unsuitable for connection between buildings. Use a fiber
optic-based extender module instead.
Extender modules with Fiber Interface:
Extender modules with fiber connections can also be used with applications in environments which are
subject to electromagnetic interference.

4.2 System Overview
4.2.1 KVM Extender - Structure
A pair of KVM extenders 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, or 6-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.
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. 1.

4.2.2 KVM Extender - Numbering of the Chassis Slots
The numbering of the slots in the chassis runs from bottom left to top right (2-/4-/6-slot chassis) and from
left to right (21-slot chassis). The slot numbering is relevant for the placement of an SNMP module in a
backplane chassis (see example) or a USB 2.0 stand-alone module in chassis without backplane (slot 2).

4.2.3 KVM Extender - Embedded Audio Signals
The extender modules offer the option of transmitting video signals with embedded audio signals, which
can be played back directly from connected monitors with integrated loudspeakers.
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
