CONNECTING AND OPERATING THE GEFEN VGA RS232 EXTENDER Cable Skew and Color Divergence Control To reduce the amount of crosstalk between twisted pairs within a CAT-5 cable, the rate of twist varies for each twisted pair. The rate of twist affects the length of each twisted pair and is referred to as cable skew. Normally, when a video signal with a single white line is displayed on the screen, each color component (red, green, blue) combines with the other to create the white line.
CONNECTING AND OPERATING THE GEFEN VGA RS232 EXTENDER The VGA RS232 Extender allows for compensation of cable skew using three (3) DIP switch banks, located on the bottom of the Receiver Unit. To access the DIP switches, peel back the small strip of silver-grey tape. Each DIP switch bank controls a different color component: Red, Green, and Blue.
RS-232 SERIAL CONTROL 54321 12345 9876 6789 Only Pins 2 (RX), 3 (TX), and 5 (Ground) are used on the RS-232 serial interface This feature allows for easy integration into automated systems capable of transmitting RS-232 commands.
