1 PAL and NTSC compatible 10-bit ADL sampling Frame sync on optional board Loop type ref. Input Five-line adaptive comb filter EDH generation and insertion Crystal Jitter filter Double SDI output To be fitted in DVR-MV/RK rack CONVI 104R-M 09/04/2005 1

2 1.0 OVERVIEW The CONVI104R converts a composite video signal into an SDI signal according to the ITU-R601 standard. The SDI output is double. The product, consisting of a plug-in, can be fitted in the Elpro DVR-MV/RK 19" 2RU rack. Like all Elpro plug-ins, the CONVI104R is self-powered and consists of two parts: -The actual plug-in that can be inserted in the rack from the front. -The rear box, called CRB104, that can be fastened with two screws in the rear part of the rack. The CONVI104 plug-in can be fitted with an optional FRAME SYNCHRONIZER board that provides two SDI synchronous outputs with an analogue reference signal that enters through the REF. LOOP input. The SDI output signals contain the EDH packet. 2

3 2.0 FRONT PANEL The following are located on the front panel of the CONVI104R: 2.1 Green FRAME sync. led which, if ON, indicates that the optional FRAME SYNCHRONIZER board has been installed inside and that the look to the external REF. LOOP signal is active. 2.2 Green SDI OUT led which, if ON, indicates a correct SDI signal in output. 2.3 Green ON led 3.0 INSTALLATION 3.1 Insert the rear box CRB104 in the rear part of the DVR-MV/RK rack, supporting the BNC connectors with the two screws provided. Insert the CONVI104R plug-in in the rear part of the rack, securing it with the two pawls already screwed to the front panel of the plug-in. 3.2 Connect the DVR-MV/RK rack to the 230 Vac 50Hz mains supply Connection of the yellow/green wires (Y/G) of the cable leading out of the rack is compulsory. The green ON led must light up on all the plug-ins inserted in the rack. The DVR-MV/RK rack accommodates any Elpro plug-in compatible with the rack. The CONVI104R converter does not have internal presets. 3

3.3 Connect the composite video source to be converted to the BNC identified as CV IN with coax cable RG59B/U For excellent conversion results, the input should be integral and immune to losses.

4 3.3 Connect the composite video source to be converted to the BNC identified as CV IN with coax cable RG59B/U For excellent conversion results, the input should be integral and immune to losses. Therefore, if the source is close enough to the CONVI104 (max. 20 mt), there is no need to compensate losses due to the cable that carries the signal. If the source is at more than 20 mt, it is advisable to offset losses using a DA104 or DA204 type equalizing distributor that can be fitted in the same DVR-MV/RK rack. The DA104 or DA204 must be inserted immediately before the input of the CONVI If the optional FRAME SYNCHRONIZER board is installed and a synchronized output is required, connect the reference signal to the REF. LOOP BNC. The reference signal may be a Black Burst or a standard composite signal. If it is not used, terminate the free REF. LOOP BNC with a 75Ω termination 4

3.5 With a suitable VFM601i type instrument, monitor the output signal of the OUTPUTS SDI1 and SDI2 BNC and check that the characteristics of the eye, jitter, amplitude and rise time comply with

5 3.5 With a suitable VFM601i type instrument, monitor the output signal of the OUTPUTS SDI1 and SDI2 BNC and check that the characteristics of the eye, jitter, amplitude and rise time comply with ITU-R601 requirements, namely: a) Eye : clearly defined b) Jitter : less than 500 psec c) Amplitude :800mV ± 10% d) Rise and fall time: 1.2 nsec If the eye is not clearly delimited or jitter is >500 psec Check that the source has a standard PAL or NTSC signal "Typical SDI waveform" 3.6 Connect the SDI destinations to OUTPUTS SDI1 and SDI2 BNC with coax cable RG59B/U The drive capacity of the CONVI104 makes it possible to connect destinations at up to 200mt. The destinations must have an input with a good Ret. Loss (min. 16dB at 270MHz) and must presents an input signal compensation and reclock circuit. The Elpro SD104 product, the SDI 1X6 signal distributor, f.i. has these characteristics. 5
