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.

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.

The VSTL report explicitly identifies the DS950 central-tabulator result path as a closed local area network.
not publicly establishedPublic-network path
The reviewed DS950 accuracy-test passage does not describe a public-network transmission path.
not publicly establishedField network state
No jurisdiction switch, port, address, enabled-service, or cable record is established in this dossier.
Operational details withheld
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.
