INSTALLATION AND OPERATION INSTRUCTIONS

INTRODUCTION

Thank you for purchasing your American Fibertek MR-915C-SL singlemode video receiver with bi­directional multi-protocol data and bi-directional contact closure. Please take a few minutes to read
these installation instructions in order to obtain the maximum performance from this product.

FUNCTIONAL DESCRIPTION

The MR-915C-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-915C-SL also supports
two bi-directional data channels. These data channels are configured as follows:
Channel 1: RS485 (2 or 4 wire) data, RS422 data, RS232 data, or Manchester data

Channel 2: Contact Closure (dry)

NOTE: This unit is shipped with Channel 1 in the RS485 4-wire configuration. For other
configurations, please refer to the DATA CONFIGURATION section for changes to the default
switch settings.

The MR-915C-SL is designed to operate with the MT-915C-SL or RT-915C-SL video transmitter with
bi-directional data over one multimode fiber optic cable.

The MR-915C-SL multiplexes a single video output signal along with up to two data signals into a high
speed serial data stream. This serial data stream modulates a laser at 1310 nm wavelength. The MR­915C-SL also detects and demultiplexes a return optical serial data stream signal containing up to two
data channels at 1550 nm wavelength. The 915C-SL Series product is designed to operate over an
optical loss budget range of 0 to 21 dB when used on 9 um singlemode fiber. Refer to the product
specification sheet for additional performance data.

The RS485 channel may be configured for 2-wire (half duplex) or 4-wire (full duplex) 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-915C-SL is designed for mounting as a modular stand alone unit. For a rack mounted version
please see the RR-915C-SL.
