3. Device description
LinkBone 8x8 Matrix Switch allows switching digital and analog signals between two sets of eight
bidirectional ports. One set of ports with labels A to H represents matrix column. Second set of ports
with labels I to P represents matrix row. The device internal switching matrix can connect any
column port with any row port. Gold cladding on internal switching contacts ensures very low
resistance and failure rate. In order to maximize the contact life time all switching contacts are cut
off from external atmosphere to prevent from corrosion and oxidation. The state of internal
switches does not change after interruption or disconnection of power supply which allows limiting
power consumption in standby mode to minimum. The architecture of LinkBone instruments
provides high reliability of switching for wide range of signal voltage levels and current values.
The block diagram illustrating the connection of input/output ports is shown in figure 1. Ports
with symbols from A to H represent matrix column and ports from I to P matrix row. The switching
matrix includes 64 relay switches allowing connecting any row port with any column port. Each
switch state is set by user configuration independently. All lines can route electrical signals
bidirectionally between ports. Meaning that each port can operate as an input or output. To prevent the
accumulation of electrostatic charge that can damage connected devices, each port is connected to
ground via a 5.1 MΩ resistor. For detailed port parameters and characteristics please refer to
chapter 10 (Specifications).
Due to internal construction of signal ports, there are two LinkBone Switch types:
-8x8 Matrix: each port contains only one line for routing electrical signals
-Dual 8x8 Matrix: each port has two symmetrical lines for routing electrical signals with
numbers 1 and 2 (e.g. for stereo audio or differential signals)

The device operates in two port switching modes:
-single – only one connection it allowed between two selected ports from matrix row and
column. This mode is dedicated for applications where only two ports can be connected
simultaneously. To avoid short circuit of multiple ports during the switching procedure first
all ports are being disconnected and then final connection is established.
-multi – multiple ports can be connected via matrix switch network.
NOTE: because several ports can be shorted together during switch operation, proper
protection circuits/techniques are needed to avoid damage of connected equipment.
The port connection configuration can be done via touch screen located on the front panel or
remotely via Ethernet, RS-232 or infrared remote control.
The access via Ethernet interface is possible by following services::
-HTTP server with user configuration page described in chapter 5.1 (HTTP server)
-Telnet server accepting text commands described in chapter 7 (Text commands accepted by
LinkBone Switch 8x8 Matrix/D al 8x8 Matrix type)
The switch control via RS-232 interface is done by using text commands with syntax similar to the
Telnet server commands described in chapter 7 (Text commands accepted by LinkBone Switch 8x8
Matrix/D al 8x8 Matrix type).
Additionally the switch status can be configured by included RC5 infrared remote control.
