INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek MT-3340-12VDC singlemode video transmitter with bi-
directional RS232 and bi-directional RS422. Please take a few minutes to read these installation instructions in
order to obtain the maximum performance from this product.
FUNCTIONAL DESCRIPTION
The MT-3340-12VDC operates as half of a transmitter / receiver pair for the transmission of a baseband NTSC,
PAL, RS170, or RS343 video signal with bi-directional RS232 data and bi-directional RS422. It is designed to
operate with the MR-3340-12VDC or RR-3340 video receiver over one singlemode fiber optic cable.
The MT-3340-12VDC converts a single video input, a RS232 data input, and a RS422 data input into an optical
output using a 1310 nm wavelength source. The MT-3340-12VDC also converts an optical input signal returning
on the same fiber into a RS232 data output and a RS422 data output using a 1550 nm wavelength detector. The
3340 Series product is designed to operate over an optical loss budget range of 0 to 21 dB. The MT-3340-
12VDC operates on 9 um singlemode fiber. Refer to the data sheets for detailed specifications.
This unit is contained in a compact and rugged aluminum housing with internal dc voltage regulation. The
detachable terminal blocks and LED indicators provide for easy installation and monitoring of video, data, and dc
power.
The MT-3340-12VDC is designed for mounting as a modular stand alone unit. For a rack mounted version
please see the RT-3340.
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 12 volt DC power source for proper operation. ANSI/NFPA 70 Class 2 wiring is
recommended.
POWER CONNECTION
Power is supplied to the unit via a two pin terminal connector on the side of the unit. See label on unit for proper
orientation of input power.
