Does serial↔CAN forwarding require the host?

No. Auto-forwarding between serial and CAN runs on the module itself, with the forwarding map configured programmatically. The host only pushes the configuration — the forwarding path neither occupies the host link nor depends on host load. Data can be forwarded to the zero-slot module (host) in parallel for real-time processing.

Where does long-run test data go, and can storage fill up?

Serial and CAN data are stored locally on the module in date-based files, with capacity managed by the module itself — the oldest data is removed automatically when space runs short, so long unattended runs are not interrupted by a full disk. Stored data can be retrieved over FTP and similar means.

GUXI Series

Serial / CAN Communication Module

16 full-duplex differential serial ports plus 4 CAN channels on one card — parallel multi-device testing from a single module
Each serial port switchable between RS422 / RS485 / RS232 with an individually shielded ground; baud rate configurable 800bps~500kbps
4 CAN channels (2 dual-channel), configurable up to ≥1 Mbps, CAN2.0B with CAN2.0A compatibility
Programmable auto-forwarding between serial and CAN — no host intervention required
Date-based on-board storage with automatic capacity management, FTP retrieval and real-time forwarding to the zero-slot host
All parameters saved automatically and reloaded at power-on; 100% domestic chips, running inside the chassis or standalone over gigabit Ethernet
