Page 4: Introduction
1. Introduction SM09 is a video distribution amplifier module. It accepts a PAL/NTSC/SECAM or PAL/NTSC 960H input and provides 8 simultaneous outputs. Each output is individually buffered and filtered. SM09 requires 5VDC which is provided via the supplied AC-DC converter. -

The adaptor accepts AC between 100 and 240VAC – the full specification is provided in Appendix A. Connect the 5VDC jack from the adaptor to the +5VDC ‘Power in’ socket on the SM09. The ‘Video In’ BNC centre should light up yellow. -
Page 6: Sm09 Technical Details
The +5VDC from the AC/DC power adaptor is filtered and protected from over-range or reverse polarity inputs by a resettable fuse. This fuse will protect the SM09 until the out-of-range condition is removed when it automatically reset itself. The 5VDC input is then regulated to provide a ‘clean’... -

– unused outputs may be left unconnected. The SM09 has a nominal gain of x1 (0dB) when the output is terminated in 75Ω. Because of the series termination each output can drive long lengths of cable without overshoot or ringing of the signal. -
