Motherboards that sit on the line, not in a rack
A factory line is not a data center: warm cabinets, 24V rails, vibration and serial devices that will not be replaced next year. The boards below were picked for those realities — PoE vision ports, six COM channels, CAN and a DC input that follows the plant rail.
POE LAN · 6 COM · CAN · DC 9–36V · −20/+60°C
On The Line
Four realities of a 24/7 cell
- Machine vision: the AD743AW carries three Intel i226-V 2.5G ports with PoE on LAN2/3 — compact cameras and small switches feed off the board itself, with no extra injector boxes in the cabinet.
- MES and traceability: six COM ports on the AD743AW, TOP600B and RP7003AW connect scanners, printers and station PCs the way the line already speaks, with RS232/RS485 selectable on COM1/2.
- Motion and control: the RP7003AW pairs two CAN buses with six COM — servo and sensor clusters share one board, and an 8-bit GPIO header covers lamp-and-button logic.
- Environment: −20 to +60°C operating with DC 9–36V on the AD743AW and RP7003AW rides 24V plant rails and cabinets that run warm for years.
Recommended Models
Three boards for the typical cell
Each card lists only what the model page states. Selection reasons reference the same datasheet fields — nothing certified, nothing invented.
AD743AW
Alder Lake-N · x7425E–N50
PoE LAN2/3 on 3× i226-V 2.5G, six COM with RS485/RS422, CAN + I2C, DC 9–36V.
Why: PoE on two LAN ports powers vision cameras without injectors; DC 9–36V and −20/+60°C match line cabinets.

TOP600B
Alder / Raptor Lake · 28W
Six COM with RS485 on COM1/2, LPT/PS/2/GPIO, watchdog 0–255 s, dual i226 2.5G.
Why: six serial ports plus a code-ready watchdog serve MES stations that must recover on their own; B-Key 4G/5G with Micro-SIM backhauls line data.

RP7003AW
Core 12th/13th Gen · U/P
Six COM with BIOS-select RS485, 2× CAN, M.2 2280 PCIe 5.0 x4, DC 9–36V 120W.
Why: CAN plus RS485 covers motion and line control; the PCIe 5.0 M.2 slot leaves headroom for analysis workloads at the cell.

| Vision camera feed | PoE LAN2/3, 3× i226-V 2.5G | AD743AW |
| MES serial farm | 6× COM, RS232/RS485 | AD743AW · TOP600B · RP7003AW |
| Fieldbus to controllers | 2× CAN | RP7003AW (AD743AW: CAN + I2C) |
| Self-recovering stations | Watchdog 0–255 s | TOP600B |
| Line data backhaul | B-Key 4G/5G + Micro-SIM | TOP600B (RP7003AW: B-Key USB 2.0/3.0 + PCIe) |
Questions
Factory automation, answered
The AD743AW carries three Intel i226-V 2.5G LAN ports with PoE on LAN2/3, so compact vision cameras can be powered from the board itself instead of a separate PoE injector stack.
The AD743AW, TOP600B and RP7003AW each offer six COM ports with RS232 on most channels and RS232/RS485 selectable on COM1/2 — the AD743AW also makes RS422 selectable in BIOS on COM1/2, so a scanner bank, a label printer and the station PC share one board.
The AD743AW and RP7003AW accept DC 9–36V and ride 12V or 24V rails directly; the TOP600B runs on DC 12–19V, so pair it with a small converter where the cell is fed at 24V.

Six COM, PoE and a 24V rail — that is a line, not a spec sheet.
