INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek RR-913 multimode video receiver with bi-directional
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 RR-913 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 RR-913 also supports up to three bidirectional 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 or RS232 data
Channel 2: RS422 or RS232 data
Channel 3: RS422 or RS232 data
Or:
Channel 1: RS422 or RS232 data
Channel 2: RS485 (2 or 4 wire) or Manchester data
Channel 3: RS422 or RS232 data
Or:
Channel 1: RS485 (2 or 4 wire) or Manchester data
Channel 2: RS485 (2 or 4 wire) or Manchester data
Channel 3: Not available in this configuration
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 RR-913 is designed to operate with the MT-913 or RT-913 video transmitter with bi-directional data
over one multimode fiber optic cable.
The RR-913 multiplexes up to three data signals into a high speed serial data stream. This serial data
stream modulates a laser at 1550 nm wavelength. The RR-913 also detects and demultiplexes a return
optical serial data stream signal containing a single video input signal along with up to three data
channels at 1310 nm wavelength. The 913 Series product is designed to operate over an optical loss
budget range of 0 to 12 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 designed for rack mounting in either of two American Fibertek subracks available. The
subrack model numbers are SR-20/2 or SR-20D/2. Slide in rack mounting, detachable terminal blocks,
and LED indicators provide for easy installation and monitoring of video, data, and optical power.
The RR-913 is designed for rack mounting only. For a modular stand alone version please see the MR-
913.
