SeRoSys CAN and CAN FD Product Lineup
Two dongles, one software suite. Both the Desk CAN Pro and the Lab CAN Pro are dual-channel CAN 2.0 and CAN FD interfaces with the same CAN engine, and both include a lifetime SLSS CANAnalyser licence with no subscription. The question is simply whether your testing happens next to a PC or away from one.
This page is the overview. For every figure side by side, see the full technical specifications.
Desk CAN Pro — $389
The starting point for professional CAN work. Two independent channels, CAN 2.0 and CAN FD, male and female pass-through DB9 so you can tap a live bus without breaking it, and software-switched termination. It is USB powered and designed to sit on a desk or bench beside the PC running the analysis.
- Dual-channel CAN 2.0 and CAN FD
- Male + female pass-through DB9, CiA® 106 pinout
- Software configurable bus termination
- Live monitoring, software logging and standalone message sending
- DBC decoding, TCP/IP API and J2534 pass-thru
- $389 MSRP, SKU STDCP10
Lab CAN Pro — $495
Everything the Desk CAN Pro does, plus the hardware for testing away from a laptop. It records to its own micro-SD card, takes power from the vehicle through the D-SUB connector, drives and reads automotive-grade GPIO, replays recorded traffic back onto the bus, and carries a Qwiic port for peripherals.
- Everything in the Desk CAN Pro
- Hardware logging to micro-SD with no PC attached
- Power over D-SUB, +7 V to +28 VDC, protected against reverse battery and transients
- GPIO: 2 inputs and 2 outputs, automotive grade
- Bus playback onto either channel
- CAN message triggered capture
- Qwiic port for peripherals, including synchronized A2B and CAN logging
- $495 MSRP, SKU STLCP10
Accessories
| Accessory | Price | What it is for |
|---|---|---|
| Qwiic Connector Cable | $5.00 | Links a Lab CAN Pro to a Flextech AKT A2B Bus Monitor for A2B logging. SKU STLQC. |
| Universal mounting bracket | — | Fixes either dongle to a bench, rig or vehicle so it does not hang off the harness. |
What both models include
These are the same on the Desk CAN Pro and the Lab CAN Pro, so they are not a reason to pick one over the other.
- Two independent CAN channels, CAN 2.0A, CAN 2.0B and CAN FD
- 1 microsecond timestamps and a 1,000,000 message ring buffer
- Lifetime SLSS CANAnalyser licence — one purchase, no recurring fee
- DBC decoding, so raw bytes are shown as physical values
- J2534 pass-thru driver (API 04.04) with CAN FD, for OEM diagnostic and reprogramming tools
- TCP/IP interface and documented API for automation
- ASC, BLF and TRC log import
- Mounting bracket support
How the two differ
Only these rows differ. Everything else is shared.
| Capability | Desk CAN Pro | Lab CAN Pro |
|---|---|---|
| Hardware logging to micro-SD | No | Yes |
| Power over D-SUB | No | Yes |
| GPIO (2 in, 2 out) | No | Yes |
| Bus playback | No | Yes |
| CAN message triggered capture | No | Yes |
| Qwiic peripheral port | No | Yes |
| Price | $389 | $495 |
Choosing between them
Pick the Desk CAN Pro if the dongle lives on a desk or bench next to a PC. On the CAN side it is the same instrument as the Lab model — same channels, same bit rates, same timestamp resolution, same buffer — and it is $106 cheaper.
Pick the Lab CAN Pro if any of these apply: the test has to run with no laptop attached, you need to power the dongle from the vehicle, you want to trigger on or drive external signals, you want to replay recorded traffic onto a bus, or you need A2B logging over Qwiic.
If you are comparing against PEAK, Ixxat, Kvaser or Vector, the competitor comparison covers that. For every specification side by side, see the technical specifications.
Frequently asked questions
Is the CAN performance different between the two?
No. Both run two independent channels at up to 1,000 kbit/s arbitration and up to 10,000 kbit/s in the CAN FD data phase, with 1 microsecond timestamps. The Lab CAN Pro costs more for its standalone and in-vehicle hardware, not for a faster interface.
Is the software licence included?
Yes, with both. The SLSS CANAnalyser licence is for life and there is no subscription or annual fee.
Can the Desk CAN Pro log without a PC?
No — it logs through the software to the PC. The Lab CAN Pro is the model with the micro-SD slot for logging on its own.
Which model do I need for A2B logging?
The Lab CAN Pro, plus a Qwiic cable and a Flextech AKT Pocket A2B Bus Monitor. The A2B and CAN logging guide covers the full setup.
Do you sell to companies on purchase orders?
Yes. See corporate purchases, or contact us.
