Page 5: Introduction
URA-232-XT Any UTP or STP Cable Table 1 – Model Number Differences The Models URA-232 and URA-232-XT do not have any special cable requirements since they are capable of correcting the RGB color skew induced in typical CATx cable installations. -

Configurable Discrete Input Contact Closure Voltage (5-30 vDC) • Software GUI 2. Installation 2.1 Package Contents Your package should contain the URA-232/URA-232-XT receiver unit, a Universal power supply (5 VDC @ 2A), an IEC320 Power Cord, and a User Manual. -
Page 7: Connection To Compatible Senders
PC (VGA) & HD (YPbPr) AV with RS232 over Twisted-Pair Receivers 2.2 Connection to Compatible Senders The URA-232 and URA-232-XT units accept a single UTP cable connection from any of Hall Research’s compatible UVA-232 Sender product line. Some compatible senders are listed below:... -
Page 8: Cable Requirements
All units provide high-frequency compensation (to account for the losses in the CATx cable) and RGB skew correction. 2.4 Daisy-Chain Limitations The Model URA-232-XT allows downstream receiver units to be daisy chained using UTP cables. This eliminates the need for running separate cables from every receiver back to the sender. -
Page 9: Configuration & Operation
PC (VGA) & HD (YPbPr) AV with RS232 over Twisted-Pair Receivers 3. Configuration & Operation 3.1 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 12: Why Skew Adjustment
Model URA-232 & URA-232-XT 3.4 Why Skew Adjustment? UTP cables have 4 twisted pairs inside. The Hall Research UVA/URA video transmission on UTP uses 3 individual pairs for each color (Red, Green, & Blue). Figure 6 - skew mechanism, example As shown in the figure above, a characteristic of CAT5/5e/6 cable is that the pairs of wires twist at different rates. -
