Page 8: Overview
CAT5 cable input. A small universal power supply is included with the AC155A-R3. • The AC155A-R3 can recover the VGA and audio signals from UTP or STP (CAT5/5e/6) cables up to 1000 feet (300 meters) long with little to no degradation. The Receiver features a proprietary circuit to allow the user to compensate for signal losses in long cable runs. -

Page 11: Installation
Connect a monitor and powered speakers to the Receiver’s VGA and AUDIO OUT connectors (see Figure 2.2). Attach the supplied power supply to the AC155A-R3 (Figure 2.1) and plug it in the AC power outlet. Figure 3.1 below shows a typical installation... - Page 12 NOTICE Do not connect this unit to any LAN device such as network cards or hubs as this may damage the AC155A-R3 and/or the LAN device. Use EIA/TIA 568B standard straight-through patch wiring as shown below. Do not use crossover cables.
- Page 13 Compact CAT5 Audio/Video Receiver Tips on Cable Selection for Best Image Quality The AC155A-R3 compensates for high frequency losses in the cable. However, due to the twist ratio differences in the UTP cable, it is recommended to use UTP cables that are specifically designed for video transmission. These cables are commonly referred to as zero or low skew cables.

Page 14: Configuration & Operation
Compact CAT5 Audio/Video Receiver 4. Configuration & Operation 4.1 Why Cable Compensation? All cables attenuate (reduce) the high-frequency components of the video signal that is being transmitted. The longer the cable, the more signal loss. If not compensated for, this signal loss will result in blurry and smeared images being displayed. -
Page 15: Compensation Adjustment Procedure
Compact CAT5 Audio/Video Receiver 4.2 Compensation Adjustment Procedure • Press the SELECT button once to enter the adjustment-mode (that is, without first hitting SELECT button the up and down arrows are inactive). • In adjustment-mode, all 3 LEDs on the unit will be turned on. •... -
Page 16: Advanced Adjustment (Cat Xawg)
Figure 4.2 – Effect of adjustment on the smearing 4.3 Advanced Adjustment (CATx AWG) The AC155A-R3 automatically equalizes the brightness of the video as the smearing is reduced. This automatic adjustment is based on the assumption that typical 24 AWG CATx cable is being used. -

Compact CAT5 Audio/Video Receiver 5. Troubleshooting 5.1 Problems/Solutions Problem: Fuzzy, blurry, or ghosting image at remote location Solution: If you have a stable image but it looks somewhat blurry (e.g. the edges are not sharp), make sure that you have adjusted the receiver unit’s HF compensation correctly. - Page 18 Compact CAT5 Audio/Video Receiver Problem: Shaking image or periodically blanking monitor Solution: Although CAT5 cable uses twisted pairs to transmit the signals from the Splitter to the Receivers to reduce the amount of EMI coupled noise from other external sources, a strong electromagnetic noise field can cause instability in the signal.
