Overview

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 (purchased separately) 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  
The Power Connect feature applies as long as the cable can carry power.  
This feature is available when using STP cable and the distance does not  
exceed 50m (164ft) on standard CAT 5 cable. For longer distances, heavier  
gauge cable should be used (TP cable is still suitable for the video/audio  
transmission, but not for feeding the power at these distances). For units  
which are connected via RJ-45 connectors, 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).  
For a TP cable exceeding a distance of 50m, separate power supplies should  
be connected to the transmitter and to the receiver simultaneously.  
3.2 Shielded Twisted Pair (STP) / Unshielded Twisted Pair (UTP)  
We recommend that you use Shielded Twisted Pair (STP) cable, and stress  
that the compliance to electromagnetic interference was tested using STP  
cable. There are 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.  
In cases where there is skewing, our Unshielded Twisted Pair (UTP) skew-  
free cable, Kramer BC-XTP, may be advantageous, and UTP cable might

Your FC-50 RS-232 Range Extender  
also be preferable for long range applications. In any event when using UTP  
cable, it is advisable to ensure that the cable is installed far away from  
electric cables, motors and so on, which are prone to create electrical  
interference.  
3.3 Recommendations for Achieving the Best Performance  
To achieve the best performance:  
Use only good quality connection cables1 to avoid interference,  
deterioration in signal quality due to poor matching, and elevated noise  
levels (often associated with low quality cables).  
Do not secure the cables in tight bundles or roll the slack into tight coils  
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

Connecting the FC-50 RS-232 Range Extender  
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 connection1 between  
the RS-232 port and the PC/device  
CROSSED for a crossed wire connection2 between  
the RS-232 port and the PC/device  
.
5. Connect the 12V DC power adapter to the power socket on the FC-50 and  
connect the adapter to the mains electricity (not illustrated in Figure 3).
