[Vetroc_daq_sbs] LVDS->ECL (solved)

[Carlos Ayerbe]

Hi All, 

Ben Raydo came this morning to help me with the ECL signal issue into VETROC.

He found that the patch panel (LVDS->ECL) has a lot of broken fuses. Unluckly (or lucky for future) I was trying the setup to VETROC from one of the broken lines, BUT when I checked the signal I took a working line (it was for convenience due to the situation of the panel). 

For future scenario, there are two green LED which should be ON if the fuses are working correctly. In my case one fuse was OFF.

This afternoon, I will go to the electronics lab and get a few fuses to repair the panel and have some spares in case we will use this panel within the hall in the final set up. 

Just as reminder in case we will use them, each panel comprises 16 ports. Each panel is powered +-6V. GRINCH will use 35 NINO cards, so we will need 3 of this panels. 

Anyhow, this option is still under discussion until we understand what and how the repeaters proposed by Bogdan work or if these panels are enough. 

Thank you
