ADDENDUM  
Addendum No.: C1648M ADDEN  
Date: April 29, 2005  
Manual Affected: FT85081/FR85081 Fiber Transmitter and Receiver  
Installation Manual – C1648M  
Manual Update: Attachment of Ferrite to Data Cable of FT85081 Transmitter  
A snap-on ferrite is supplied with the FT85081MSTR,  
FT85081SSTR, and FT85081SFCR transmitters. The ferrite  
must be attached to the data cable of the transmitters to  
comply with FCC and CE emissions requirements.  
After data connections are made to the data connector on  
the transmitter, attach the ferrite to the data cable. When  
attaching the ferrite to the cable, position the ferrite as  
close as possible to the transmitter.  
NOTE: The ferrite should fit securely around the cable.  
If the ferrite is loose and slides along the cable, loop the  
cable through the ferrite before closing the ferrite.  
If, however, the thickness of the cable prevents the ferrite  
from closing, use a tie wrap to hold the ferrite in place  
rather than looping the cable.

DATA COMMUNICATION SETUP  
NOTE: As a matter of convenience, it is recommended that you set the desired data  
communication before mounting the FT85081 transmitter/FR85081 receiver into a rack  
or onto a wall.  
The Data Selection switch, which is located on the rear panel of the FT85081 transmitter/  
FR85081 receiver, is a 10-position rotary switch that allows you to set the data communication  
required for the transfer of data (refer to Figure 6).

Note the following:  
The FT85081 transmitter/FR85081 receiver allows data translation between RS-232 and  
RS-422 signal levels. Consequently, the Data Selection switch can be set to 0 (RS-232)  
on the transmitter and to 1 (RS-422) on the receiver. Conversely, the Data Selection  
switch can be set to 1 (RS-422) on the transmitter and to 0 (RS-232) on the receiver.  
If you wish to change the data communication setting after the FT85081 transmitter/  
FR85081 receiver has been powered on, power off the transmitter/receiver, change the  
data communication setting, and then power on the transmitter/receiver again.  
MOUNTING  
The FT85081 transmitter/FR85081 receiver can be mounted into a rack or can be used as a  
standalone module. As a standalone module, the unit can be placed on a desktop or can be  
mounted to a wall.  
NOTE: As a matter of convenience, it is recommended that you set the desired data  
communication before mounting the FT85081 transmitter/FR85081 receiver. To set the  
desired data communication, refer to the Data Communication Setup section.  
MOUNTING THE TRANSMITTER/RECEIVER INTO A RACK  
The FT85081 transmitter/FR85081 receiver can be installed into the RK5000 Series rack mount  
chassis, which can be mounted into an industry-standard 19-inch (48.26 cm) equipment rack.  
The RK5000 Series rack mount chassis includes the following models:  
RK5000PS-3U and RK5000-3U: Designed to accommodate fiber optic modules as  
follows:  
The RK5000PS-3U rack mount chassis provides 12 single-width module slots and  
a power supply.  
The RK5000-3U rack mount chassis provides 14 single-width module slots (a  
power supply is not included). Power to the modules can be supplied using the  
optional external power supply (EPS5000-120).  
For additional information, refer to the RK5000PS-3U/RK5000-3U Fiber Rack Mount  
Chassis Installation manual.

RK5000PS-5U: Designed to accommodate Enduramodules but can also  
accommodate fiber optic modules with the use of the appropriate adapter kit. The  
RK5003-1UEXP adapter kit is required for installation of the FT85081 transmitter/  
FR85081 receiver into the RK5000PS-5U chassis.  
For information about the RK5000PS-5U chassis, refer to the RK5000PS-5U Rack Mount

that occupies three slots in the RK5000PS-3U, RK5000-3U, and RK5000PS-5U chassis.  
MOUNTING THE TRANSMITTER/RECEIVER USING THE WALL CLIP  
NOTE: Before mounting the FT85081 transmitter/FR85081 receiver to a wall, ensure  
that there is adequate space at both ends for viewing the front-panel LEDs and for  
making the various rear-panel cable connections.  
To attach the FT85081 transmitter/FR85081 receiver to a wall using the supplied wall clip, refer  
to Figure 7 and do the following:  
1. Using the two vertical or horizontal wall-mounting holes, attach the wall clip to a wall  
using two screws (not provided).  
2. Slide the module into the clip until the two holes on the bottom of the module align with  
the two holes on the lower flange of the clip.  
3. Attach the module to the clip using the two Phillips pan head screws provided for the clip.

CONNECTIONS  
Connections to the FT85081 transmitter and the FR85081 receiver are made on the rear panel  
of the modules and consist of the following:  
Power connection  
NOTE: A 12 VDC or 24 VAC power supply can be used to power the transmitter/receiver  
power supply is used, the power supply must be a Listed Direct Plug-In Power Unit  
marked as Class 2 and rated as 24 VAC, 200 mA (minimum output).
