INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek MRM-1600P multimode mini video
receiver. Please take a few minutes to read these installation instructions in order to
obtain the maximum performance from this product.
FUNCTIONAL DESCRIPTION
The MRM-1600P operates as half of a transmitter / receiver pair for the transmission of
baseband NTSC, PAL, RS170, or RS343 video signals and return control for Panasonic
‘up-the-coax’ systems. It is designed to operate with the MTM-1600P or RTM-1600P
video transmitter over a single multimode fiber optic cable.
The MRM-1600P converts a FM modulated optical input into a single video output using
a 1300 nm wavelength detector. The MRM-1600P also converts an electronic camera
control signal into an optical control signal returning on the same fiber using an 850 nm
wavelength source. The M1600P Series product is designed to operate over an optical
loss budget range of 0 to 12 dB. Panasonic allows a maximum transmission distance of
up to 1.6 km (1 mile) for their ‘up-the-coax’ protocol. The MRM-1600P operates on 50
um or 62.5 um multimode 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 block and LED indicator provide for easy
installation and monitoring of video and dc power.
The MRM-1600P is designed for mounting as a modular stand alone unit. For a rack
mounted version please see the RRM-1600P.
INSTALLATION
THE INSTALLATION OF THIS UNIT SHOULD BE MADE BY A QUALIFIED SERVICE
PERSON(S) AND MUST CONFORM TO ALL LOCAL CODES.
Mount the unit to a secure surface using #8 (3mm) hardware in four places. Mounting
dimensions can be found on the connection diagram included with this manual. Be sure
to allow sufficient room for the required minimum bend radius of the fiber cable used.
POWER SOURCE
The unit requires a +12VDC power source for proper operation. The DC input is diode
protected. In the USA and in Canada an American Fibertek PS-12 is supplied with this
unit. The negative side of the power input is directly connected to ground. ANSI/NFPA
70 Class 2 wiring is recommended.
POWER CONNECTION
Power is supplied to the unit via a two pin terminal connector. Follow label on unit and
customer connection drawing for proper orientation of +12 volt dc and ground.
INPUT / OUTPUT CONNECTIONS
The fiber optic connection is made via a ST connector located on the side of the unit.
