OPERATING THE UNITS
Once the connections have been made and power applied, there is little in the
way of operational adjustments required. With the exception of the MIC AUDIO
adjustment on the 1T-VGAST-CAT-XL transmitter described above, only two
adjustments are possible on the 1T-VGA-CAT product line and a total of three
are possible on the 1T-RGB-DELAY product.
5.1 1T-VGAST-CAT-XL & 1T-VGA-CAT-RXL Adjustments
On the 1T-VGAST-CAT-XL receiver module and on the 1T-VGA-CAT-RXL
receiver module, there are two adjustments.
1T-VGAST-CAT-XL 1T-VGA-CAT-RXL
If the picture appears to be “weak” or lacking in color fidelity, adjust the control
labeled “GAIN” to improve the image. (Note that you will increase noise in the picture
at higher gain settings so a compromise will have to be found if the CAT 5 cable run
is at the limit.)
The other adjustment is for Equalization. On long cable runs, the high frequency
detail can be lost resulting in a “Soft” looking picture. This will first show up in text
where the characters will lose their sharp edges. Adjust the control labeled “EQ” to
sharpen the image. As was true of the Gain control, you can introduce noise in the
picture with this adjustment so seek a setting where the picture quality is improved
without adding a great deal of noise (often called “Snow”) to the picture.
