THE ACS335A KVM-EXTENDER FAMILY
Welcome to the ACS335A KVM-Extender
Family!
Thank you for purchasing a ACS335A KVM-Extender model. We appreciate your business,
and we think you'll appreciate the many ways that your enhanced keyboard/video/ mouse
system will save you money, time, and effort.
That's because our ACS335A KVM-Extender not only allows you to remotely locate a
console (Monitor, Keyboard, Mouse + optional serial/audio devices) over great distances
without any loss in signal quality (up to 1000m/3250ft) but also to do this in an EMI
hazardous environment.
Wherever you have great distances: airports, roller plants, distributed data centres; or in a
range of applications where you have large electromagnetic generators or loads, magnetic
resonance tomographs, induction furnaces, current generators; the ACS335A KVM-Extender
is a solution for remotely locating your console. Two different models cover a range of
applications: a KVM extender for a standard remote console – Monitor, Keyboard and
Mouse; and a second unit with KVM extension and additional serial and bi-directional audio
support. This device is also suitable for computers equipped with a serial mouse or touch
screen.
This manual will tell you all about your new ACS335A KVM-Extender, including how to
install, operate, and troubleshoot it. For an introduction to the Extender,
see Chapter 2. The Extender product codes covered in this manual are:
ACS335A: KVM-Extender for VGA, PS2-Keyboard/Mouse
ACS335A-AS: KVM-Extender for VGA, PS2-Keyboard/Mouse + Serial/Audio

  • Page 23 Brightness Brightness/Contrast controls on ACS335A – Extender On each ACS335A KVM-Extender you can adjust Brightness and Contrast manually. You’ll find the potentiometers to the right hand of the fibre connectors on the Remote unit. Please use these potentiometers for adjustment of all colours simultaneously.
  • Page 24 ACS335A –5 STRAND KVM-EXTENDER On the front panel of the Remote unit there are potentiometers to adjust the gain of each colour signal. In the mode 'With AGC', these potentiometers have no function. In the mode 'Without AGC' you can adjust the factory setting for the gain of each single colour. This may be necessary if there is a different attenuation between the three lines.

  • Page 31 MONITOR SETUP VGA in/RGB out This application uses the extender as a VGA/RGB Converter. The attached monitor must be able to display an RGB signal with the provided frequencies. You can only use an RGB Monitor with a VGA-Signal if the Monitor is able to process the SYNC frequencies (for example, a monitor with HSYNC = 40-90 kHz may not work from VGA with 640x480 = 31,5 kHz).

    MONITOR SETUP 5.2 Hints for Pixel Clock and Pixel Phase Why do you need to adjust Pixel clock and Pixel phase (always in this order) when you are using a TFT screen? This can be explained by means of a 'virtual' reduced system, which has only a few pixels and lines displaying a burst pattern (see above).
