Procurement Notes

Verify that the specific part number DC-EM-02T-C corresponds to the wired Ethernet variant within the Digi Connect EM family. Confirm hardware revisions and regulatory approvals such as FCC Part 15 Class B compliance prior to procurement. Ensure compatibility with existing development tools like the Digi JumpStart Kit if software integration is required.

Selection Notes

Select this module when a pin-compatible, long-term available solution is needed for wired connectivity. It serves as a direct alternative to wireless variants in the same family, offering identical form factors and processor capabilities without the WLAN radio components. Verify power requirements against the system's 3.3VDC supply constraints.

Part Context

This component belongs to the Digi Connect EM family, which allows for interchangeable hardware designs between wired and wireless modules. The family utilizes a common platform approach to simplify product development and ensure long-term availability through Digi’s NET+ARM technology.

Replacement Considerations

The Digi Connect Wi-EM series offers a pin-compatible wireless alternative within the same family. For direct replacements, verify specific ordering suffixes and hardware revisions to ensure functional equivalence.
