EQUALIZATION & BOOST SETTINGS

Each 1:5 Splitter For HDMI Over CAT-5 receiver contains a Dip Switch bank located on the underside of the unit. This bank of 4 Dip Switches are covered with a piece of silver metallic tape. These Dip Switches will modify boost settings and change the equalization mode.

EQUALIZATION MODES

Dip Switch 1 is used to select the equalization mode. There are 2 EQ modes to select from. Auto Equalization (Dip Switch 1 = Off, default) will automatically attempt to equalization the incoming signal and eliminate and digital noise that may occur due to variances in cable skew. Manual Equalization (Dip Switch 1 = ON) will allow the user to manually EQ the signal using the Trim Pot located on the front panel of the receiver. By default, Auto Equalization is set and is effective for CAT cable runs of up to 130 feet. Distances greater than 130 feet should be manually equalized. Use the table below for quick reference of the EQ Dip Switch modes.

BOOST MODES

Dip Switches 3 and 4 are used to specify the boost strength of the signal from the 1:5 Splitter For HDMI Over CAT-5 sender. This feature will boost the signal when long distances of cable are used and will also help the signal reach the receiver when low quality cable is used. There are not set distance rules in regards to this setting (due to the variances in cable quality), so it is recommended that the user try all settings, starting with no boost, when troubleshooting issues. Please refer to the table below for the 4 different Dip Switch combinations.
