Frequently Asked Questions - 673R/T Kramer

What is the maximum distance supported by the Kramer 673R/T?

The Kramer 673R/T can extend video up to 150 meters using Cat5e/6 cable.

What type of video signal does the 673R/T support?

It supports VGA (analog RGB) or composite video signals, depending on the model variant.

Does the 673R/T require a power supply for both units?

Typically, only the transmitter (673T) requires power; the receiver (673R) may be powered via the Cat5 cable (PoC) or an optional adapter.

Can I use it with a Cat6 cable instead of Cat5e?

Yes, Cat6 is fully compatible and may provide better performance over longer distances.

What is the resolution limit of the 673R/T?

It supports resolutions up to 1920x1200 (WUXGA) or 1080p at 60Hz.

How do I connect the 673R/T to my devices?

Connect the source (e.g., PC) to the transmitter via VGA, then run a Cat5/6 cable from transmitter to receiver. Connect the display to the receiver via VGA. Optionally, connect audio via 3.5mm jacks.

Is there any software required for the 673R/T?

No, the extender is plug-and-play; no drivers or software needed.

What do the LED indicators on the 673R/T mean?

A green LED indicates power; a blinking or solid LED may indicate signal presence. Check the manual for exact behavior.

Can I daisy-chain multiple 673R/T extenders?

No, the 673R/T is designed for point-to-point extension only. For longer distances, use a single longer cable or a repeater.

What should I do if there is no video output?

Check that all cables are securely connected, the power supply is plugged in, and the source is outputting a compatible resolution. Try a different Cat5/6 cable or reset the units.

3 Overview

The 673T is a high-performance fiber optic transmitter for 3G HD-SDI, HD-SDI, SDI, and dual-link SDI signals. The unit converts up to four channels of serial digital signals on gold-plated BNC connectors to light pulses that are transmitted over a single multimode fiber optic cable to a 673R receiver that converts them back to serial digital signals. The 673T and 673R pair has a transmission range of 1000 meters (more than 3,200ft).

Both the 673T and 673R:

• Feature a maximum data rate of up to 3Gbps, enabling it to be used for standard definition, high definition and the new 3G high definition serial digital video signals (SD/HD-SDI)
