INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek RTM-1600P multimode mini video transmitter. Please take a few minutes to read these installation instructions in order to obtain the maximum performance from this product.
FUNCTIONAL DESCRIPTION
The RTM-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 MRM-1600P or RRM-1600P video receiver over a single multimode fiber optic cable.
The RTM-1600P converts a single video input into a FM modulated optical output using a 1300 nm wavelength source. The RTM-1600P also converts an optical control signal returning on the same fiber into an electronic camera control signal using an 850 nm wavelength detector. This electronic camera control signal is sent back to the camera on the same coax cable that the video originated on. 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 RTM-1600P operates on 50 um or 62.5 um multimode fiber. Refer to the data sheets for detailed performance specifications.
This unit is designed for rack mounting in any of the three American Fibertek subracks available. The subrack model numbers are SR-20/1, SR-20R/1, and SR-20/2. Slide in rack mounting and LED indicators provide for easy installation and monitoring of video and power.
The RTM-1600P is designed for rack mounting only. For a modular stand alone version please see the MTM-1600P.
INSTALLATION
THE INSTALLATION OF THIS UNIT SHOULD BE MADE BY A QUALIFIED SERVICE PERSON(S) AND MUST CONFORM TO ALL LOCAL CODES.
The unit slides into any open slot in the SR-20 subrack. Use a small screwdriver to push and lock the two ¼ turn fasteners into place.
POWER SOURCE
Power to the unit is supplied by the subrack. Please refer to the SR-20 and PSR instructions for further details.
POWER CONNECTION
Power is supplied to the unit via a four finger backplane connector. The RTM-1600P can be inserted into the subrack or removed from the subrack with power applied to the backplane.
INPUT / OUTPUT CONNECTIONS
The fiber optic connection is made via a ST connector located on the back of the unit. Be sure to allow sufficient room for the required minimum bend radius of the fiber used.
