Hi Mike,

Just to be clear:

After we receive the Nicomatic connectors, make one more T-Board/cable 
assembly that is the same as the one you did, and 2 more with a right angle 
turn but from the other direction than the one you did.
At this point, let's not put Nicomatic connectors on the remaining two V2 
T-Boards.

We only need 4 total of the V2 T-Board/Cable assemblies which we will ship to 
Zhenyu before June 13th.  When the new V2.1 T-Boards are available, we will 
assemble the remaining 6 production cables to 6 of the V2.1 T-Boards, 3 of 
each right angle option.

Zhenyu, please let us know if this summary is not correct.

Regards,
Steve Valentino

We will try to fully populate one inner hybrid and one outer hybrid. They 
will be connected to two T-boards, separately, to get maximum flexibility. 4 
(=2+2) cables are in case a cable get damaged or not working.
