INSTALLATION AND OPERATION INSTRUCTIONS 

 

INTRODUCTION 

 

Thank you for purchasing your American Fibertek Series 8823C-SL singlemode eight channel 
video multiplexer with return AD/Bosch Manchester control and bi-directional RS232 data. 
Please take a few minutes to read these installation instructions in order to obtain the maximum 
performance from this product. 
 

FUNCTIONAL DESCRIPTION 

The 8823C-SL Series units operate as a transmitter / receiver pair for the transmission of eight 
simultaneous, real time baseband NTSC / PAL video signals with return Manchester control and 
RS232 data over one singlemode fiber optic cable.  
 
The MTX-8823C-SL transmitter accepts up to eight video inputs and multiplexes these signals 
along with the data signals onto a single optical output port for connection to the fiber 
transmission system. Correspondingly, the MRX-8823C-SL receiver converts the optical signal 
to eight independent video output signals along with the data signals. 
 
This link can accommodate both a return Manchester data interface and a bi-directional RS232 
interface. These interfaces function independent of each other and can be used individually or 
concurrently. 
 
The 8823C-SL Series units operate on 9 um singlemode fiber. Refer to the data sheets for 
detailed performance specifications. 
 
The individual units may be configured for rack mounting or wall mounting depending upon the 
position of the included mounting hardware. 

 
INSTALLATION 

THIS INSTALLATION SHOULD BE MADE BY A QUALIFIED SERVICE PERSON AND 
SHOULD CONFORM TO THE NATIONAL ELECTRICAL CODE, ANSI/NFPA 70 AND LOCAL 
CODES. 
 
To install the MTX-8823C-SL or MRX-8823C-SL it is first necessary to mount the rack flanges to 
the unit. 
 
For rack mounting the ears are installed on the 
sides of the unit with the surfaces that have 
oval holes flush with the front of the unit as in 
Figure 1. Mount the ears with the #10 flathead 
screws provided. To mount in the rack cabinet, 
use mounting screws that are appropriate for 
the rack cabinet being used.
