Two FMCSA-registered OBD-II ELDs — here's how they differ and which one fits your trucks.
The PT-30 (Pacific Track) and IOSiX ELD are the two most common FMCSA-registered OBD-II ELD devices used by small-fleet software providers. Both plug into your diagnostic port, both pass DOT inspection, and both work with ELD Hub for $15/truck/month. The differences come down to vehicle compatibility, diagnostic depth, and price. Here's the honest side-by-side so you can pick the right one — or keep the hardware you already own and just switch software.
| PT-30 connector | OBD-II (16-pin) with 6-pin and 9-pin adapters |
| IOSiX connector | 9-pin (Class 8) or 6-pin (Class 3–7) direct — OBD-II adapter available |
| PT-30 vehicle fit | Best for Class 3–7 and mixed fleets on 2010–2019 trucks |
| IOSiX vehicle fit | Best for 2020+ Class 8 tractors and heavy-duty diagnostic depth |
| Connectivity (both) | Bluetooth to driver phone/tablet, embedded cellular for uploads |
| FMCSA registration | Both on the official FMCSA ELD list |
| Price with ELD Hub | $15/truck/month — device included either way, no contract |
Neither is universally better — it depends on your fleet. PT-30 is the right call for mixed fleets, owner-operators, and Class 3–7 straight trucks because it's cheaper and the OBD-II adapter fits almost everything. IOSiX is the right call for Class 8 tractors (2020+ model year) because the 9-pin connector pulls richer diagnostic data. If you're not sure, call ELD Hub at 302-404-1177 with your truck year/make/model and we'll pick.
Yes. PT-30 (Pacific Track PT30) and IOSiX ELD are both on the official FMCSA ELD registration list. Either one satisfies the ELD mandate under 49 CFR 395.20.
In most cases yes. If you're leaving TT ELD, Factor ELD, GPS Tab, Motive, or another provider that uses PT-30 or IOSiX hardware, we can re-register your existing device to ELD Hub — no new hardware purchase required. Call 302-404-1177 to check compatibility.
PT-30 retails around $150–200 per unit. IOSiX retails around $180–250. With ELD Hub the hardware is included in your $15/truck/month subscription either way — no hardware fee, no shipping charge, no contract.
No. Both PT-30 and IOSiX include embedded cellular chips, and the data is bundled into your ELD Hub subscription. Nothing to configure, no SIM cards to manage.
PT-30 wins on install speed — plug it into the OBD-II port under the dash, done in 5 minutes. IOSiX takes about 10 minutes because the 9-pin connector routes through a harness. Neither requires a mechanic or ECM programming.
Both have multi-year hardware warranties. IOSiX has a slight edge on durability for long-haul Class 8 sleepers because the housing tolerates higher engine-bay temperatures. For day-cab and regional fleets the PT-30 lasts just as long in real-world use.
That's the most common case for small fleets under 20 trucks. Run PT-30 on the Class 3–7 straight trucks and IOSiX on the Class 8 tractors — ELD Hub handles both device types in one dispatcher dashboard. No extra fee for mixing hardware.
