KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview
3 Overview
The high-quality Kramer MultiTOOLS FC-50 RS-232 Range Extender can
connect either to a PC or to a device (for example, a switcher). By
connecting two units via a CAT 5 cable, the PC can control the switcher
over a range of up to 1000 meters (3300 feet).
In particular, the FC-50 features:
• Bidirectional RS-232 operation
• The Power Connect feature
• A CONNECTION switch to select between a crossed and a
straight connection
• A PC/DEVICE pushbutton that is pressed or released if a device
or a PC, respectively, are connected to the RS-232 port
• 12V DC power
3.1 About the Power Connect Feature
Power Connect feature applies as long as the cable can carry power.
The
This feature is available when using STP cable, and the distance does not
exceed 50m on standard CAT 5 cable. For longer distances, heavy gauge
cable should be used
make sure that the shield of the STP cable is connected to the metal casing
of the connectors on both ends of the cable. For units which are connected
via terminal block connectors, the shield of the STP cable must be
connected to a ground terminal on the units at both ends (use the ground
terminal of the power supply connection if necessary).
1
. For units which are connected via RJ-45 connectors,
For a CAT 5 cable exceeding a distance of 50m, separate power suppli es
should be connected to the transmitter and to the receiver simultaneously.
3.2 Shielded Twisted Pair (STP) / Unshielded Twisted Pair (UTP)
recommend that you use Shielded Twisted Pair (STP) cable. There are
We
different levels of STP cable available, and we advise you to use the best
quality STP cable that you can afford. Our non-skew-free cable, Kramer
BC-STP is intended for analog signals where skewing is not an issue. For
cases where there is skewing, our UTP skew-free cable, Kramer BC-XTP,
may be used. Bear in mind, though, that we advise using STP cables where
possible, since the compliance to electromagnetic interference was tested
using those cables.
1 CAT 5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances
3
Your FC-50 RS-232 Range Extender
Although Unshielded Twisted Pair (UTP) cable might be preferred for long
range applications, the UTP cable should be installed far away from electric
cables, motors and so on, which are prone to cre ate electrical interference.
However, since the use of UTP cable might cause inconform ity to
electromagnetic standards, Kramer does not commit to meeting the standa rd
with UTP cable.
3.3 Recommendations for Achieving the Best Perfor mance
hieve the best performance:
To ac
• Use only good quality connection cables
1
to avoid interference,
deterioration in signal quality due to poor matching, and elevated
noise levels (often associated with low quality cables).
• Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer FC-50
away from moisture, excessive sunlight and dust

To connect two FC-50 units, as illustrated in the example in Figure 3, do
the following:
1. Connect a PC to the RS-232 port of the first FC-50 unit and release the
PC/DEVICE button.
2. Connect the RS-232 port of the second FC-50 unit to a device (for example,
a switcher) and push in the PC/ DEVICE button .
3. Connect the CAT 5 RJ-45 connector of the first unit to the CAT 5 RJ-45
connector of the second FC-50 unit via UTP cabling.
4. Set the CONNECTION switch independently on both units as follows:
STRAIGHT for a straight wire connection
RS-232 port and the PC/device
CROSSED for a crossed wire connection
