The 6-digit serial numbers of all your OPN2002s will have to added at 'Tools >
Options > Polling and Timing > Terminals to Poll'.

When using the CRD200, don't configure a Poll Speed faster than 0,5s because
once an OPN2002 is communicating to the host, the other OPN2002s will be
temporarily muted for 250ms by the CRD2000 to avoid data collisions. For this
reason an OPN2002 responds to a poll after a random time ranging between
280ms and 480ms.
Mini USB cable
When using the mini-USB cable to retrieve your data from the OPN2002/3, the
RS232 configuration of NetO32 is limited to selecting the correct COM-port of
your OPN2002/3 in the RS232 configuration window of NetO32.
However, when using the mini-USB cable it's not possible to keep NetO32
running in the background due to the fact that the USB COM-port won't be
present on your system until you've physically connected your OPN2002/3 to
your USB port. Also it's not recommended to disconnect or to reconnect your
OPN2002/3 without having stopped the NetO-protocol first.
For these reasons it's easiest to place a NetO32 configuration file on your
desktop that downloads the data from the OPN2002 once and then immediately
closes again. This can be done by selecting the following 3 options in NetO32.
Protocol > Polling and Timing > Protocol type: Single
Protocol > Polling and Timing > Protocol type: Quit after single run
Miscellaneous > Appearance > Run protocol on start
The correct sequence to retrieve the data from the OPN2002/3 using the mini
USB cable would then be connecting your OPN2002/3 to the USB port, clicking
on the NetO32 configuration file and then remove the OPN2002/3 from your PC
when desired. (Don't forget it regularly needs be charged as well.)
