INSTALLATION AND OPERATION INSTRUCTIONS

INTRODUCTION

Thank you for purchasing your American Fibertek MRM-3400 singlemode video receiver with bi-directional

RS422 data. Please take a few minutes to read these installation instructions in order to obtain the maximum performance from this product.

FUNCTIONAL DESCRIPTION

The MRM-3400 operates as half of a transmitter / receiver pair for the transmission of a baseband NTSC, PAL,

RS170, or RS343 video signal with bi-directional RS422 data. It is designed to operate with the MTM-3400 or

RTM-3400 video transmitter over one singlemode fiber optic cable.

The MRM-3400 converts a RS422 data input into an optical output using a 1550 nm wavelength source. The

MRM-3400 also converts an optical input signal returning on the same fiber into a single video output and a

RS422 data output using a 1310 nm wavelength detector. The M-3400 Series product is designed to operate over an optical loss budget range of 0 to 10 dB. The MRM-3400 operates on 9 um singlemode fiber. Refer to the data sheets for detailed performance specifications.

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

The MRM-3400 is designed for mounting as a modular stand alone unit. For a rack mounted version please see the RRM-3400.

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.

Mount the unit to a secure surface using #8 (3mm) hardware in four places. See the drawing on the next page for mounting dimensions. Be sure to allow sufficient room for the minimum bend radius of the fiber cable used.

POWER SOURCE

THIS PRODUCT SHALL BE POWERED BY A LISTED CLASS 2 POWER SUPPLY ONLY.

This unit requires an isolated 12VAC power source for proper operation. In the USA and in Canada an American

Fibertek PS-12AC is supplied with this unit. ANSI/NFPA 70 Class 2 wiring is recommended.

POWER CONNECTION

2

Power is supplied to the unit via a two pin terminal connector on the side of the unit. See label on unit for proper location of input power.

FIBER CONNECTION

The fiber optic connection is made via a FC/PC connector located on the right side of the unit.

VIDEO OUTPUT CONNECTION

The video output connection is made via a BNC connector on the right side of the unit. The 75

Ω video output can be looped through typical baseband video inputs of switchers, recorders and other equipment as required.

For proper operation, the output must be terminated with 75

Ω. For optimum performance the video cables should be the shortest length of coax practical.

DATA INPUT / OUTPUT CONNECTIONS

Data input and output connections are made via a terminal block on the right side of the unit. See the label on the unit for proper orientation of input and output connections.

Data connections are based on industry standard EIA terminology for the transmission of electronic data signals.

Using this terminology, the driver of an electronic signal is labeled TX or data out. Correspondingly, the receiver of an electronic signal is labeled RX or data in. Therefore, when connecting two devices via copper wires, the data out of one device is connected to the data in of the other device. Not all manufactures follow standard EIA terminology. Consult the installation instructions for your copper device if you are unsure which two wires are the drive (data out) wires and which two wires are the receive (data in) wires.

In addition, please note that Data In on the MRM-3400 becomes Data Out on the MTM-3400 or the RTM-3400 after going across the fiber. The reverse flow follows the same orientation.

MRM-3400 STATUS INDICATOR

The MRM-3400 provides the following LED status indicator to aid in installation and troubleshooting:

OLI

A bi-color LED indicator monitors the optical input power of the video/data signal that is being received at the

MRM-3400 from the MTM-3400 or the RTM-3400. Internal DC power and optical input status associated with this LED are summarized below.
