CONNECTING THE DVI RS232 EXTENDER 1. Connect the DVI source to the DVI RS232 Extender sending unit’s DVI input port using the supplied DVI cable. 2. Connect the RS-232 source to the DVI RS232 Extender sending unit’s RS-232 input port using the supplied DB-9 serial cable. 3. Connect the DVI RS232 Extender sending and receiving units together using two user supplied CAT-5, CAT-5e or CAT-6 cables. NOTE: If field terminating network cable, please adhere to the TIA/EIA568B specification.
HOW TO EQUALIZE THE VIDEO SIGNAL The DVI RS232 Extender has built-in auto equalization that will automatically tune out any unwanted video noise. This feature is reliable with premium cable runs up to a maximum of 130 feet. If your cable run is beyond 130 feet, it may be necessary to use manual equalization. The sender and receiver units both have sets of DIP switches located on the underside of their enclosure. Remove the silver metallic tape to expose these DIP switches.
ADDITIONAL DIP SWITCH FUNCTIONS FORCE RGB AND PRE-PROGRAMMED EDID FEATURES DIP switch 1 on the 4-bank DIP switch located on the underside of receiver unit enables and disables the automatic equalization function. Additional features can be enabled by using the other DIP switches on this bank. FORCING THE RGB COLOR SPACE In some cases, the output video may have a pink or green tint. This usually is attributed to the output device (e.g. display) not supporting the color space being used by the source device.
