[dsg-hallb_rich] [EXTERNAL] USB extender for raspberries

[Tyler Lemon]

Hi Luca,

I've ordered two of the USB repeater cables.

For the Raspberry Pis, where are they located on Sector 1?

Getting the Raspberry Pis may have to wait until closer to the installation time of RICH-II since Sector 1 isn't very accessible unless the forward carriage is moved.

Ciao Tyler,
I just talked to Marco regarding the unavailability of Raspberries worldwide; we decided to go with the old 2 Raspberries already installed on Sector 1. We plan to relocate one of those on Sector 2. In order to connect both cameras of each sector to one Raspberry we need proper active USB extender, so we ask if you can buy two of these:

They are reported in stock, but if you have trouble with this you can order also somewhere else, just check that it's USB2.0, the length is 5m and that it's an active extender: the simple passive prolongation cables will not work, since there are already many meters inside the RICH and the maximum length of USB2.0 is 5m.

Thanks,
Luca
