Can Condor 1553 boards be either transformer or direct coupled?

Yes - coupling can be configured as direct coupled or transformer coupled via software, jumpers, or cable selection.

The PCI-1553, ISA-1553, DT-1553, VME-1553, VXI-1553, and QPMC-1553 are software-selectable for transformer or direct coupling with an API call. Refer to the specific product documentation for the applicable API call.

The cPCI-15553, PMC-1553, and IP-1553 (and modular-based solutions) are jumper-selectable. Refer to silkscreen on the PCB or consult the User's Manual for appropriate coupling selection.

The PCCARD-1553 is cable-selected for coupling. The long pair of wires is for connecting to transformers (note label). The D9 connector is provided for users that wish to build a Direct Coupled cable.

The MS-1553 product line is jumper-selectable. Refer to silkscreen on the PCB or consult the User's Manual for appropriate coupling selection.
