200$ coupons are not suitable for S17 ASICs, nor for S9j/S9k.
Mikeywith, a hero member here with high reputation and also with great knowledge in Bitmain coupons business clearly stated the same thing, here

I mentioned they don't work on T17 series, they do work on S17s tho, the problem is, saving a 100$ is not really good enough for a deal for me, this coupon has an expiry conditions, 190$ coupons have no expiry conditions and you can pretty much get them for 90$ if you have the right contacts.
