Only use G &D-certified transmission modules
It is not permitted to use fiber optic modules, which do not meet the requirements of laser class 1 in accordance with EN 60825-1:2014. By using such modules, compliance with regulations and pieces of advice for the safe handling of laser technology cannot be guaranteed.
The guarantee of complying with all relevant instructions can only be given by applying original components. Therefore, the devices have to be operated with G&D-certified transmission modules only.

Introduction

By using two signal extenders of the Audio-Transceiver-Fiber series, you can transmit audio signals between a computer and a remote console via a fiber optic connection.
Audio signals are transmitted in both directions between the connected extenders.
NOTE: Signal extenders of the Audio-Transceiver-Fiber series are provided in two variants:
Audio-Transceiver-Fiber(S) transmits signals via single-mode optical fibers over distances up to 10 kilometers.
Audio-Transceiver-Fiber(M) transmits signals via multi-mode optical fibers over distances up to 550 meters.
A rotary switch lets you amplify the analogue audio signal coming in at the interface Line In/Micro In (see page 8).

Amplifying the analogue input signal

A rotary switch lets you amplify the analogue audio signal coming in at the Line In/Micro In interface. In the defaults, the rotary switch is set to 0:
NOTE: The drawing shows the digital variant of the Audio-Transceiver-Fiber series.

The following table lists the different switch settings and the respective amplification of the input signals:

Switch setting| Amplification of the analog input signal (Line In/Micro In)
---|---
0| 0 dB (no amplification)
1| 3 dB
2| 6 dB
3| 9 dB
4| 12 dB
5| 15 dB
6| 18 dB
7| 21 dB
8| 24 dB (maximum amplification)
9| 24 dB (maximum amplification)

NOTE: A high level of the input signal and the simultaneous amplification ma y lead to an overdriving of the audio signal. Decrease the level of amplification if the audio signal is distorted.

Configuration

The user is enabled to change the configuration of the signal extender in the setu p menu. This menu provides the possibility to view and edit the current configuration.
The setup menu is operated via any terminal emulation program (PuTTY, for exam-ple). The supplied service cable enables the user to connect the computer on which the terminal emulation program is installed to the Service socket of the signal extender.
Preparing the computer to use the setup menu
Before the setup menu can be called up, install a device driver to address the Service socket and set a connection to the terminal emulation program.

Installing the device driver

Before adjusting the connection in the terminal emulation program, install th e device driver CP210x USB to UART Bridge VCP.
This driver provides the Service socket of the KVM extender, which is connected vi a service cable, as virtual serial interface (COM port). Now, the virtual interface can be selected in the terminal emulation program to establish the connection.
How to install the device driver to address the Service socket:

Use the computer’s web browser to open the homepage www.gdsys.com/en.
Go to More from G&D > Tools & Drivers.
Download the device driver for the operating system of your computer.
Run the file and follow the instructions of the installation wizard.

Adjusting a connection in the terminal emulation program
How to adjust the connection in the terminal emulation program:

Start any terminal emulation program (HyperTerminal or PuTTY, for example).
Create a new connection in the terminal emulation program and enter the fol-lowing connection settings:

Bits per second:	115.200
Data bits:	8
Parity:	none
Stop bits:	1
Flow control:	none

Connect the Service interface of the signal extender’s transmitter or receiver to one of the computer’s USB interfaces. Use the supplied service cable for this purpose.

The setup menu lists all signal extender settings in tabular form:
