The ZImager CoaXPress route remains open between fiber transceivers and local compute. Cable coiling, storage, and routing are external to the ZFront EBox; the readout route does not pass through the EBox. The detector-to-readout connections are in the ZImager harness.

Team notes: Calibration source inventory, controller count, actuator type (including motor versus air), enclosure layout, panel identities, and connector families remain open. The present CXP-6 copper run-length estimate is 40–60 m, motivating the fiber-transceiver or local-compute choice.
