INSTALLATION AND OPERATION INSTRUCTIONS

INTRODUCTION

Thank you for purchasing your American Fibertek MR-913C-SL singlemode video receiver with bi­directional multi-protocol data. Please take a few minutes to read these installation instructions in order
to obtain the maximum performance from this product.

FUNCTIONAL DESCRIPTION

The MR-913C-SL operates as half of a transmitter / receiver pair for the transmission of high
performance 10 bit digital NTSC, PAL, RS170, or RS343 video signals. The MR-913C-SL also supports
up to three bi-directional channels of RS485 (2 or 4 wire), RS422, RS232 or Manchester data. Switch
selection allows for multiple data configurations in one of the following three formats:

Channel 1: RS422, RS485-(2 or 4 wire), Manchester, or RS232 data
Channel 2: RS422, RS485-(2 or 4 wire), Manchester, or RS232 data
Channel 3: RS422, RS485-(2 or 4 wire), Manchester, or RS232 data

NOTE: This unit is shipped in the following default configuration. For other configurations,
please refer to the DATA CONFIGURATION section for changes to the default switch settings.
Channel 1: RS422 data

Channel 2: RS485 (4 wire) or Manchester data
Channel 3: RS232 data

The MR-913C-SL is designed to operate with the MT-913C-SL or RT-913C-SL video transmitter with
bi-directional data over one singlemode fiber optic cable.

The MR-913C-SL multiplexes a single video output signal along with up to three data signals into a
high speed serial data stream. This serial data stream modulates a laser at 1550 nm wavelength. The
MR-913C-SL also detects and demultiplexes a return optical serial data stream signal containing up to
three data channels at 1310 nm wavelength. The 913C-SL Series product is designed to operate over
an optical loss budget range of 0 to 21 dB. Refer to the data sheets for detailed performance
specifications.

The RS485 channel may be configured for 2-wire (half duplex) or 4-wire (full duplex) operation with or
without biasing. Switch selectable internal 120 ohm terminations are available for RS422 or RS485
data.

This unit is contained in a rugged aluminum housing with internal dc voltage regulation. The detachable
terminal blocks and LED indicators provide for easy installation and monitoring of video, data, and
optical power.

The MR-913C-SL is designed for mounting as a modular stand alone unit. For a rack mounted version
please see the RR-913C-SL.
