1.0 OVERVIEW Thanks for purchasing this product. Please check the contents of the packing. It contains: - The unit - The present user manual - The Power Supply is a 1 x 2 high resolution RGBHV distribution amplifier. It's compatible with many standards as: - Composite (triple 1x2 CVBS distributor) - Component YUV - Computer RGBHV - RGBS (Composite sync. SUN, SGI) - RGsB (Sync On Green) unit receives signals from the source by 5 BNC. The two BNC outputs can be buffered to reach the distance up to 100 m without losses.
2.0 POWER is powered only by the AC adapter equipped with the unit. Units don't have adjustment or setting inside. Servicing must be made by qualified personnel. The adapter must be fitted in a 220-240 Vac/50 Hz socket. 3.0 SETTINGS The ensure compatibility of with the whole of sources either broadcast or informatics, input impedance of H (Comp.) automatically conforms to the source. If the source gives a TV negative sync, it will be terminated at 75 Ohm. In the other cases the input will remain in high impedance. By a dip-switch accessible from the bottom of the unit the output can be buffered. 1 BOOST :In On pos. the BNC outputs are buffered. For length equal or greater than 50 m. The switch BOOST must be set in ON pos. The unit is factory-set as follows: 1 BOOST :OFF
4.0 INSTALLATION a) Be sure that all units to be installed are in OFF state. b) Connect the source to INPUT RGBHV by a RG59 B/U cable. ATTENTION If your source gives signals RGB+S connect the S to the BNC H. If your source gives the Sync On Green leave open the BNC H are V. If your source has an HDD 15 p.f. as output connector, use a COMM-TEC adapter cable as an interface. c) Connect the two destination with BNC RGBHV output by a RG59 B/U cable. d) Power the unit as described in chapter 2.0 and check that the led POWER on front panel lights up. ATTENTION does not process the sync. So the destinations must be compatible with the source. If they aren't it's necessary to interpose an interface type COMM-TEC IF-11V or IF-12VA ATTENTION The length of cables which bring RGB signals must be the same with a tolerance of 0,5 m. Greater difference may cause a significative loss of the image resolution.
5.0 ACCESSORIES The following items are included with the unit: - Power Adapter The following items are available on request: - RMK-2HE: 19" Rack Mount Kit for 2 units, 2 RU - RMK-2HE-BLK: Blank Panel for RMK-2HE 6.0 TECHNICAL DATA Name Function : :high resolution signals distributor RGB signals :analogue Input impedance 75 Ohm Coupling :DC Crosstalk (worst case) :>30 db at 40 MHz Diff. amplitude :0.1% Diff. phase :0.1 H Sync.
