INSTALLATION AND OPERATION INSTRUCTIONS

INTRODUCTION

Thank you for purchasing your American Fibertek RTM-30, which consists of three
multimode video transmitters. Please take a few minutes to read these installation
instructions in order to obtain the maximum performance from this product.

FUNCTIONAL DESCRIPTION

The RTM-30 operates as half of a transmitter / receiver pair for the transmission of three
baseband NTSC, PAL, RS170, or RS343 video signals over three strands of multimode
fiber optic cable. Each of its three independent optical outputs is designed to operate
with the MRM-100, RRM-100, or RRM-30 video receiver. The RTM-30 contains the
electronics and optics of three RTM-100 units mounted on one printed circuit board to
save space and reduce cost.

The RTM-30 converts three video inputs into three separate FM modulated optical
outputs using an 850 nm wavelength source for each signal. The M30 Series product is
designed to operate over an optical loss budget range of 0 to 12 dB with a maximum
distance of up to 2.5 km. The RTM-30 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-30 is designed for rack mounting only. For a single channel modular stand
alone version please see the MTM-100.

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. Please note that when installing this card in
the position directly next to the power supply in the SR-20 subrack, it may be necessary
to make the signal connections at the rear of the card before fully seating the card into
its slot.

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-30 can be
inserted into the subrack or removed from the subrack with power applied to the
backplane.

INPUT / OUTPUT CONNECTIONS

Fiber optic connections are made via ST connectors located on the back of the unit. Be
sure to allow sufficient room for the required minimum bend radius of the fiber optic
cable used.

Video input connections are made via BNC connectors on the back of the unit. Video
inputs should be connected to an appropriate 75Ω baseband video source such as a
camera or a video recorder output. For optimum performance the video cables should be
the shortest length of coax practical.

RTM-30 STATUS INDICATORS

The RTM-30 transmitter provides the following LED status indicators to aid in installation
and troubleshooting:

VLI 1 THROUGH VLI 3

A bi-color LED indicator is provided for each of the video inputs to the RTM-30. DC
power and video status associated with these LEDs are summarized below.

Video Presence LED DC Power Status Video Status
