Source-linked configuration dossier
ES&S EVS 6.4.0.0 / DS950
A separate source-linked dossier for the certified DS950 central-count scanner/tabulator, including firmware and hardware revisions, documented motherboard and storage changes, output-transport firmware, central-count cart, and certified UPS alternatives.

A certified component list does not prove what a jurisdiction installed. A jurisdiction system-version listing does not prove device firmware, configuration-change adoption, internal parts, or power topology.

Safe public evidence boundaryReviewed 2026-07-21
The EVS 6.4.0.0 Pro V&V report states that DS950, DS850, and DS450 results were transmitted to the EMS through a closed local area network during accuracy testing. The EAC scope includes the central tabulator, Electionware infrastructure, and a minimum-1-Gb network switch, but it does not establish a jurisdiction's live switch, port, or addressing configuration.
This view publishes only the laboratory-supported closed-LAN result path and its source limits. It excludes IP addresses, credentials, keys, database details, switch settings, VLANs, hostnames, device identifiers, and site-specific routing.1 sourced configuration view2 source imagesNo field-observed topology collected

EVS 6.4.0.0 central-tabulator closed-LAN test path
Pro V&V tested DS950 result transmission over a closed LAN to the EMS. The EAC scope separately lists a minimum-1-Gb switch among certified COTS hardware. The public passages support the system-level path but not every physical connector or a field installation.

No addresses, credentials, keys, database identifiers, switch settings, VLANs, hostnames, device identifiers, or site routing is collected or displayed.
A VSTL accuracy-test topology is not proof that a jurisdiction connected a DS950, used the listed switch, or transmitted results over a network in a particular election.

Findings and public status
Tests, limitations, and listing gaps
Neutral finding types replace a generic “bugs” bucket so affected versions and source scope remain visible.
vstl test campaign resultnone reported in test campaign
No anomalies reported in the EVS 6.4.0.0 certification campaign
Pro V&V reported no anomalies during EVS 6.4.0.0 testing and recommended certification after the system met applicable VVSG 1.0 requirements.
A bounded test result is not evidence that every fielded DS950 is defect-free or a claim about misconduct or outcomes.

Deployment evidence
Dated jurisdiction observations
Deployment records remain at their documented grain. A system-level observation does not establish unit components, firmware, change adoption, or power configuration.
not collected
No reviewed deployment observation in this dossier
The source package currently establishes a certified configuration and test history, but no dated jurisdiction-level use record.
Absence from this catalog is not evidence that the system is unused. Deployment claims require a separately reviewed state or local source.
Jurisdiction context
Where this equipment appears in 2024 records
These jurisdiction rows are third-party administration context. A product-family name supports only that named family at the reported jurisdiction grain. A manufacturer match does not establish that a particular dossier model, component, firmware version, or certified configuration was deployed.
