examples for remote switching - IHSE GmbH

Dear customer,
active Y-switch
congratulations to purchase the active Y-switch for monitor. This product correspond to the ultimate
requisitions of quality and technics. If you still have problems with your device, please refer
to your sales office.
Please read this manual before installing and operating the unit. Please record the serial number,
the date of purchase and your sales office in the space below. The serial number is located of the
backside of the switch. These data would be important, if you ever need to repair one of the parts.

Introduction
User of personal-computers (PC) in the industry often are in need of a second working place for
their PC. For example a second control station for a machine or a PC-working place in the office
(purchasing departement) and one in the depot. With the Y-switch you may spare the installation
of a netwerk and the special software. A PC may be used from two working places. In combination
with the line extensions this second working place may be located at a distance up to 200m
(VGT/VGR, order number 002-2E, coaxial technic), or up to 1000m (VTO/VGO, order number
234-2E, fibre optical technic) from your PC.
The active Y-switch is connected to the PC with a monitor-cable (all cables are not in the schedule
of parts supplied). The sockets for the two VGA monitors and the keyboards are located on the
rear side of the unit.
The unit needs a power supply with a voltage between 8 and 28V. User in industrial plants might
connect the switch to an existing 24V driving voltage supply.
For offices we advise a 12V/500mA supply unit (e.g. order number 259-2A: 220VAC/12VDC-
500mA)

Technical data
power supply
Y-switch for monitor : 8 ... 28 Volt, e.g. plug power supply 220V/12V-500 mA
power required max. 6 Watt
interfaces
monitor : VGA / RGB analogical, band width max. 80 MHz
size
weight : app. : 0,4 kg
length/width/hight : app.: 120 x 120 x 35 mm
Power supply socket
At the screw terminal on the outside of the unit a direct current power supply between 8 and 28
Volt has to be connected. The ripple factor shouldn’t overstep 5%. A diode protects the unit in
case of reversal of the channels. The 24 V driving voltage supply used in industrial plants is sufficient.
For offices we advice a 12V power supply unit.
