Introduction
Overview
The CS261 / CS261TK is a DVI micro-processor controlled computer sharing
solution that offers a multi-user/single-tasking experience and enables two
users to share the use of a single USB computer from two separate consoles
(monitor, USB keyboard, USB mouse, speaker and microphone). The CS261 /
CS261TK is ideal for small office environments. All programs, files and
resources on any connected computer can be easily accessed and shared by
both users without the additional complexity and expense of setting up a
network environment. Users are able to operate computers on the installation
one by one while, for additional security, the other console's video and audio
output is optionally disabled.The CS261 / CS261TK even provides a
convenient OSD (On Screen Display) function that allows either of the
Consoles to access any computer connected to the system by means of an on
screen, console status driven interface.
Setup is fast and easy; plugging cables into their appropriate ports is all that is
entailed. There is no software to configure, so there is no need to get involved
in complex software installation routines or be concerned with incompatibility
problems. Because the CS261 / CS261TK intercepts keyboard input directly,
it works on any hardware platform and with all operating systems.
Responding to the growing use of audio input/output in the workstation space,
the CS261 / CS261TK has been designed with built in microphone and speaker
support, as well.
CS261TK is CS261 that bundled with KVM over IP Access Control Box. The
2XRT-0015G KVM over IP Access Control Box allows users to enable or
disable remote over IP control privilege by simply pressing a control button.
It’s fast and easy to set up the 2XRT-0015G. Simply plug the 2XRT-0015G’s
cables to the CS261 / CS261TK. There is no need to install software or
configure devices - just plug and play,.
In addition, the cable length of the 2XRT-0015G reaches 5 meters, enabling
connection to the transmitter over longer distances for more flexible
installation.
