Hey Tim, Unfortunately, the one Gb Ethernet block is exclusively for ROACH2. The ROACH-1 board only has 10GbE outputs (or XAUI) directly from the FPGA via the CX4 connectors. The only way to get data out on a slower connection is via the PowerPC on 100mb Ethernet, using either the katcp interface or running code directly on the PowerPC CPU.
