Issue Details

Can PXIe-4311 be used with TB-4310 (10V or 600V)?

Solution

No, it cannot. Although PXIe-4311 and TB-4310 may appear physically compatible at first glance, they are designed with different DIN connector keying schemes (mechanical interlocks) that prevent physical connection.

PXIe-4311: Low Voltage 1 keying — same as PXIe-4309
TB-4310: High Voltage 4 keying — same as PXIe-4310

This design is intentional and serves as a safety mechanism to prevent incorrect combinations that could lead to equipment damage or safety hazards. As of now, PXIe-4311 is intended to be used only with TB-4309.
