Elo Touch Solutions — 2 prefixes (MA-L)

A MAC address beginning with 78:B3:CE or 1C:EE:C9 belongs to Elo Touch Solutions, a touchscreen and interactive-display hardware manufacturer headquartered in Milpitas, California. Both blocks are full MA-L (/24) IEEE registrations assigned directly to "Elo touch solutions" at the same registered address, so either prefix attributes reliably to Elo hardware rather than to a shared IEEE base used by many unrelated companies.

Elo Touch Solutions traces back to Elographics, founded in the early 1970s in Oak Ridge, Tennessee by Dr. Samuel Hurst, a co-inventor of resistive touchscreen technology. Tyco International acquired the company in 1997, and it now operates as Elo Touch Solutions from Milpitas, matching the address on file with the IEEE registry exactly.

The company's current product line — touch monitors and signage displays from roughly 7 to 65 inches, all-in-one point-of-sale computers, OEM touch controllers, and self-service kiosks — matches the device population most likely to present these OUIs on a network. Elo also ships EloView for remote device management and the Android-based EloCare OS 360.

Elo's own support site publishes a knowledge-base article identifying these two prefixes as its vendor MAC addresses, corroborating the IEEE registration from the vendor side. The article body could not be fetched directly (HTTP 403 on the request), so its existence and title are confirmed but its exact wording is not.

No CVE tying a vulnerability to Elo Touch Solutions hardware or firmware is recorded in the NVD as of an August 2026 search. Two name-collision traps exist and were ruled out: CVE-2024-22372 affects unrelated ELECOM wireless routers, and CVE-2018-10197 affects ELOenterprise/ELOprofessional software from ELO Digital Office GmbH, a different German company.

IEEE's public OUI registry publishes no assignment or registration date for either prefix. Third-party lookup sites display dates such as 2013-05-02 and 2016-08-26, but those are third-party database ingestion artifacts, not IEEE facts, and are not recorded here as registration dates.

Security note

no CVE tying a vulnerability to Elo hardware/firmware found in NVD as of an August 2026 search; CVE-2024-22372 (ELECOM routers) and CVE-2018-10197 (ELO Digital Office GmbH software) are unrelated name collisions

Related entity caveat

the Wireshark manufacturer database lists 00:0A:3D under "Elo Sistemas Eletronicos S.A.", a differently-named Brazilian registrant; no verified corporate relationship to Elo Touch Solutions was established, so it is not treated as a related vendor here

Dates

IEEE's public OUI/MA-L registry publishes no assignment or registration date for either prefix; third-party "registered" dates (e.g. maclookup.app) are database ingestion artifacts, not IEEE facts [Confirmed] — https://maclookup.app/macaddress/1ceec9/mac-address-details
