Looking at the InHand IR315?
Compare it with the LINBLENET T300-280C — or T300-390.

Five Ethernet ports, serial I/O, two SIM slots — a strong mainstream unit. Here is the factual side-by-side, including which of our models to pick depending on your SIM count.

What carries over — and what to check

What carries over

  • 5 × 100 Mbps — port count exact, no extra switch needed
  • Serial I/O for meters and PLCs on both
  • Same wiring pattern: RJ45 LAN, serial terminal block, wide DC input

What you gain

  • Pick by SIM count: 280C when one SIM is enough (lower cost), 390 where two slots with automatic failover are specified
  • One serial SKU instead of fixed factory variants
  • 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: InHand Device Manager is mature; evaluate both if fleet management is central
  • Serial detail: our single port is RS-232/485 configurable; the IR315 provides both simultaneously — verify on the bench if you need two serial ports at once
  • Enclosure size: check your cut-out against the datasheet first
The second-source way to try it: keep the InHand IR315 where it works. Take one LINBLENET T300-280C / T300-390, 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.
Two SIM slots required? Quote the T300-390. One SIM is enough? The T300-280C does the same port job at lower cost.
