Looking at the Four-Faith F3X34?
Compare it with the LINBLENET T300-280C.

Five Ethernet ports and serial I/O in the same class — with one practical difference: our serial port is RS-232/485 configurable on the same unit, where the F3X34 variant is fixed at order time. Factual side-by-side for integrators.

What carries over — and what to check

What carries over

  • 5 × 100 Mbps — port count exact
  • Serial I/O for meters and PLCs on both
  • Same wiring pattern: RJ45 LAN, serial terminal block, wide DC input

What you gain

  • One serial SKU covers RS-232 and RS-485 — the F3X34 serial variant must be fixed at order time, so a mis-order means a new unit; ours is configurable in the field, which removes a stock-keeping and mis-order risk
  • Solder-down (chip) SIM support for vibration and unattended sites
  • MOQ 1 — run a real evaluation without a project-size commitment
  • Stock ships in 5–7 working days (industry norm: 4–8 weeks)
  • Private label from 1 unit; label artwork produced the same day

What to check honestly

  • Cloud platform: evaluate both if remote management is central to your offer
  • Serial detail: the F3X34 offers an RS-485/422 option — if your fieldbus is RS-422 specifically, verify support on the bench first
  • Enclosure size: check your cut-out against the datasheet first
The second-source way to try it: keep the Four-Faith F3X34 (4G) where it works. Take one LINBLENET T300-280C, run your own protocol test on your own bench, and keep it as a fallback for the weeks your main supplier's lead time slips. MOQ is 1 unit and stock ships in 5–7 working days — the industry norm is 4–8 weeks. Nothing to lose, something to fall back on.

Certificate numbers are verifiable with the issuing bodies. Need a certificate in your own company name? That is an OEM / private-label conversation — we do that from 1 unit.

Run your own test — 1 unit is enough
