BXC-CBE1 has sets of default values of TH(In-capture) and TH(In-focus), corresponding to each objective lens. The
l
values can be changed.
In-Capture / In-Focus / GND pin assignments are the same as U-AFA2M. However, other signals are assigned to
l
different pins. Therefore, all pins except In-Capture/In-focus/GND signals must be N.C.(No Connect)
