Page 7: Section 1. General Information
CAT unit will be connected to the source of the video (and possibly to the source of some audio as well). A length of cable will connect the t-CAT unit to the r-CAT unit. The cable can be CAT5, CAT5e, CAT6, or nano-skew cable. Whichever cable is used, the cable is a “straight”... -

Page 12: Video Connections
Connect the AC power transformer to a power mains outlet of the correct voltage and frequency then plug the DC power connector into the t-CAT or r-CAT. There is no power switch on the CAT Video Distribution System; it is intended to be on at all times. -
Page 13: Cat Connections
2.6 CAT CONNECTIONS Signal losses increase with transmission line length. The CAT Video Distribution System contains additional support to equalize video signals along longer twisted pair transmission lines. A full solution to accomplish this is built into the r-CAT. A combination of four DIP Switches in two banks supplies the necessary compensation to nullify the detritus effects of the cable. -
Page 14: Section 3. Troubleshooting
CAUTION: CAT5/5e/6/nano-skew cabling must be pinned to the TIA-EIA T568B wiring specification. This equipment is not intended for, nor does it support, connection through an Ethernet network. Do not connect these inputs or outputs to any sort of networking or telecommunications equipment. -
Page 15: Poor Audio Quality
3.3 POOR AUDIO QUALITY Amplified speakers are required. Ensure an amplifier drives the speakers. Check input source levels from source device. Make sure the audio source is not over or under driven. 3.4 GREEN SHIFT/GREEN WASHOUT The standard Knox product is designed to function with DC coupled signals with the black level referenced to 0 Volts. -
Page 16: Section 4. Maintenance
SECTION 4. MAINTENANCE CAUTION! There are no user serviceable parts in the CAT Video Distribution System. Do not operate unit with top cover removed. 4.1 INTRODUCTION The CAT Video Distribution System uses passive air flow (convection) to keep its power supply within a safe operating temperature range.
