<DIV>Hi Doug,</DIV>
<DIV> </DIV>
<DIV>John Melton pointed out this bug some time ago and I fixed it in a
private release that I sent him.</DIV>
<DIV> </DIV>
<DIV>I’ve just check the FPGA code in Metis V2.6b and the code to select the
wideband data is in place. </DIV>
<DIV> </DIV>
<DIV>So to start without wideband data the command is </DIV>
<DIV> </DIV>
<DIV>0x01 </DIV>
<DIV> </DIV>
<DIV>and with is</DIV>
<DIV> </DIV>
<DIV>0x03</DIV>
<DIV> </DIV>
<DIV>I’ve just tested the code using KK and it appears to work as expected.
</DIV>
<DIV> </DIV>
<DIV>Please let me know if you are still having a problem.</DIV>

I am trying to suppress Bandscope data from being sent from Metis/Mercury to the
PC. The firmware versions are Metis 2.6b and Mercury 3.4. I started the system
using the designated command as follows (in Objective-C on a MAC running OS X
10.9.2):

<DIV>
<DIV>Unfortunately, it seems to ignore the command and send both I/Q data
(endpoint 6) and Bandscope data (endpoint 4). Otherwise everything works as
expected.</DIV>

<DIV>Is this a known bug? Is there a workaround?</DIV>
