2.1 Quick Start
This quick start chart summarizes the basic setup and operation steps.
Overview

3 Overview
The 672T and 672R are an optical fiber transmitter and receiver for
computer graphics signals up to UXGA and stereo audio signals. The 672T
converts the computer graphics and stereo audio signals to an optical signal,
and the 672R converts the optical signal back to computer graphics and
stereo audio signals.
Together, the 672T and 672R form a UXGA/audio transmitter/receiver over
multimode fiber system.
The 672T and 672R pair features:
• A transmission range exceeding 1700 meters (more than 1 mile) over
multimode optical cable
• Up to 1.65Gbps bandwidth per graphic channel1
• Regulation in accordance with Class 3R Laser Eye Safety in
compliance with ANSI Z136 and IEC 60825-1:2007
• Full compatibility with the Kramer 670T/670R and 671T/671R
HDMI/DVI transmitters and receivers for non-HDCP content
• 5V DC power adapters
• Housing in Kramer DigiTOOLS® enclosures
3.1 Recommendations for Achieving the Best Performance
To achieve the best performance:
• Use only good quality connection cables2 to avoid interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables).
• Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer 672T,
672R away from moisture, excessive sunlight and dust
1 Suitable for resolutions up to UXGA at 60Hz, and for all HD resolutions

5 Connecting the 672T and 672R Transmitter/Receiver
System
To connect the 672T and 672R, do the following:
1. Connect a computer graphics source (for example, a computer graphics card
on a PC) to the UXGA IN 15-pin HD connector.
2. Connect a stereo audio source (for example, a s te reo au dio play er ) to th e
AUDIO IN 3.5mm mini jack connector.
3. Connect the UXGA OUT 15-pin HD connector to a computer graphics
accepto r (f o r exam ple , an L CD d is play ).
4. Connect the AUDIO OUT 3.5mm mini jack conn ect or to a st er eo au dio
acceptor (for example, the speakers of an LCD display).

5. On the 672R, set the SOURCE switch to VGA. (If a Kramer 670T or 671T
transmitter is connected to the 672R, set th e SOURCE sw itch to HDMI ).
6. Remove the dust caps and connec t the OPTIC CABLE connector of the
672T to the OPTIC CABLE connector of the 672R, via OM3 cabling
(maximum range of 1700 meters (over 1 mile)).
7. Connect the 5V DC power adapter to the power socket on each unit and
connect the adapter to the mains electricity (not shown in
Figure 3
).
Note: A 672T can be connected to Kramer’s 670R or 671R to convert a
VGA input to an HDMI/DVI output.
Avoid direct eye exposure into the optic connectors when powered, although this product
is regulated strictly enough to operate under the Laser Class 3R for eye safety
