[casper] 10 GbE SPF+ to 1 GbE RJ45 adapter

2017-08-10 Thread Xavier Bosch
Hi, As I explained in a previous email, I am looking for a way to send the slow-throughput ROACH2 data (~25 Mbps) to a PC without using the SPF+ ports on the PC side. Mobility is important for the project that I am working, so I want to be able to use any laptop for that purpose without the burd

Why not use the 1GbE port on the ROACH2? No need to go for 10GbE (SFP+) ports On 08/10/2017 01:16 PM, Xavier Bosch wrote: Hi, As I explained in a previous email, I am looking for a way to send the slow-throughput ROACH2 data (~25 Mbps) to a PC without using the SPF+ ports on the PC side.

Ryan, Thank you for your response. You are right, I first considered the 1 GbE port but this implies to restructure the data packaging, instead of using 64 bits of length, as I am right now. I have to change it to 8. Besides the fact that there is no much information on the 1 GbE port, but there is

Hi Xavier, Using an adapter might be possible in principle, but it definitely won't work out the box. It's probably about three orders of magnitude more design effort to get this working vs using the on-board 1gbe :) Sorry! Jack On Thu, Aug 10, 2017, 1:33 PM Xavier Bosch wrote: > Ryan, > Thank

I have not attempted the tutorial, but if I was testing the adapters, I would do something like this: 1. Take a known-working demo (which does loopback, for example) 2. Test the demo yourself and confirm it is doing loopback successfully 3. Disconnect the TX port from the ROACH and plug in your
