KRAMER: SIMPLE CREATIVE TECHNOLOGY
Defining the TP-145/TP-146
4
The TP-145 can store and recall EDID data in non-volatile memory, allowing
convenient and reliable connection to the source.
3.3 Recommendations for Achieving the Best Performance
To achieve the best performance:
• Use only good quality connection cables
1
• Avoid interference from neighboring electrical appliances that may adversely
influence signal quality, and position your Kramer TP-145/TP-146 away
from moisture, excessive sunlight and dust
to avoid interference, deterioration
in signal quality due to poor matching, and elevated noise levels (often
associated with low-quality cables)
4 Defining the TP-145/TP-146
This section defines the:
• TP-145, XGA/Audio/Data Line Transmitter (see Section
4.1
)
• TP-146, UXGA/Audio/Data Line Receiver (see Section
4.2)
4.1 Defining the TP-145 XGA/Audio/Data Line Transmitter
The TP-145 is a high-performance transmitter that accepts:
• A computer graphics input signal
• An unbalanced stereo analog audio signal
• RS-232 control commands
The TP-145 encodes the signals and transmits them over TP cable to a TP-146
receiver. The stereo analog audio signal is converted to a digital audio (S/PDIF)
stream before transmission, thus preserving the quality of the audio source signals.
Commands and data can flow in both directions simultaneously via the RS-232
interface, allowing status requests and control of the destination unit.
When the TP-145 is connected to a display device and the EDID CAPTURE
button is pressed, the TP-145 reads and stores the EDID (Extended Display
Identification Data) from the display device. This prevents the problem whereby a
