Installing A Cat5 Extender With A 2Touch Iwb - 2Touch 2150 series Installation Manual

5. USB type A cable from board into hub outlet (note additional USB

extension needed if port is placed on right side of board)

6. If 2Touch model 014 speakers supplied, then a USB type A male to

USB type B male cable will be required to connect from a hub outlet

port, to the USB input port on the active speaker. This permits the

dual USB ports on front of speakers to be available to the user.

Installing a Cat5 extender with a 2Touch IWB

In some cases, the wall panel location may be too far away from the IWB to

practically extend the USB cable using conventional USB extenders. In such a

case, the recommended practice is to use a USB-to-Cat5 extension solution.

This converts the USB signal from the board to a format compatible for

transport of Cat5 cable. At the wall panel end, the signal is reconverted to

USB, and the USB is then terminated to the wall

panel in the normal fashion.

The image at right illustrates a Lindy USB-to-

Cat5 extension solution.

Note that the use of an external power supply is

essential to the functioning of the IWB, as the

Cat5 signal itself will no longer supply the

required current to drive the USB device. The

power supply must be connected to the

conversion unit at the IWB end, not at the wall

panel end.

If the standard Lindy power supply is not used with the Lindy USB-to-Cat5

extension solution, then alternates may be acceptable provided that they

supply 5volts and at least 500mA, and that they incorporate effective voltage

regulation.

A USB-to-Cat5 extension solution might also be used in combination with a

powered USB Hub. The IWB's USB fly lead is connected in the usual way to

one of the USB hub outlets. The input side of the hub (ie computer end) is

connected to the USB-to-Cat5 solution. At the remote (wall panel) end, the

Cat5 is again converted back to USB and connected to the wall panel in the

usual way. In this situation, the use of a power supply for the USB-to-Cat5

solution is not required since the IWB is independently powered by the

powered hub (which has its own power supply).

Cautionary note: Use of power supplies with inadequate voltage regulation

can cause serious damage to the IWB's internal circuitry. Except where the

powered USB hub or the Cat5-USB conversion solution (including the power

supply) used in the installation has been supplied by 2Touch Technologies Ltd

and / or Interactive Whiteboards Australia Pty Ltd, damage to the 2Touch

IWB caused by fluctuations in voltage on the USB line cannot be covered by

warranty.
