Fanless controller has multiple serial ports

Jan 20, 2012 — by LinuxDevices Staff — from the LinuxDevices Archive — 6 views

Aaeon announced a fanless controller that features a dual-core Intel Atom D525 processor and an operating range from -4 to 140 deg. F. The AEC-6612 Rev.B includes a CompactFlash slot and room for a 2.5-inch hard disk drive, up to six serial ports and six USB ports, two gigabit Ethernet ports, and optional Wi-Fi, according to the company.

We've seen an outbreak of "Rev.B" products lately from Aaeon — the GENE-LN05 Rev. B single board computer and the COM-LN Rev.B module, for example — and all appear to involve a switch of processors from Intel's "Pineview" Atom D510 processor to the later Atom D525. That's certainly the case with Aaeon's AEC-6612 Rev.B, an embedded PC that never covered in its original form.

Frankly, the benefits of the processor change are minor: The device now accepts DDR3 memory instead of DDR2 RAM, and there's a minor clock speed bump (from 1.67GHz to 1.8GHz), but the CPU still has dual cores and a 13-Watt TDP.

According to Aaeon, the AEC-6612 Rev.B accepts up to 4GB of memory in a single SODIMM slot, and can rely either on a 2.5-inch SATA drive or a CompactFlash card for storage. It also features two gigabit Ethernet ports and digital I/O (four in, four out), the company adds.

Aaeon's data sheet says the AEC-6612 Rev.B is offered in a "B1" version, with just two USB 2.0 ports and two serial ports (one RS232, one RS232/422/485), and in a more fully featured "B2" version. (Confusingly, the image supplied earlier in this story doesn't seem to correspond exactly to either, so we guess there's an undocumented "B3" as well.)

In the "B2" guise, the AEC-6612 Rev.B has a front panel (above left) that's replete with six USB 2.0 ports and six serial ports (five RS232, one RS232/422/485). In addition to the Ethernet ports that have been already mentioned, there's a VGA output.

The controller's rear panel (above right), meanwhile, has a power intput that is capable of accepting input voltages ranging from 9 to 30VDC. Passively cooled, the AEC-6612 Rev.B is capable of working from -4 to 140 deg. F in locations where there is airlow, or up to 122 deg. F if there isn't.

Specifications listed by Aaeon for the AEC-6612 Rev.B include:

  • Processor — Intel Atom D525
  • Chipset — ICH8M
  • Memory — up to 4GB of DDR3 RAM via single SODIMM slot
  • Storage — 2.5-inch SATA drive bay; CompactFlash slot

  • Other I/O:
    • 2 x USB 2.0 ("B1") or 6 x USB 2.0 ("B2")
    • 1 x RS232/422/485
    • 1 x RS232 ("B1") or 5 x RS232 ("B2")
    • 1 x VGA
    • DIO (4 in, 4 out)
  • Power — 9~30VDC

  • Dimensions — 7.8 x 4.3 x 2.3 inches
  • Weight — 4.85 pounds

Further information

Aaeon detailed neither pricing, operating system support, nor availability for the AEC-6612 Rev.B, but the system appears to be available now. More information can be found on the AEC-6612 Rev.B product page.
