Fanless PC has dual video outputs, CFast, six serial ports

Sep 23, 2011 — by LinuxDevices Staff — from the LinuxDevices Archive — 9 views

Nexcom announced a fanless PC that offers two DVI-D video outputs and is available with single or dual PCI/PCI Express expansion slots. The NISE-3142 supports Intel Core 2 Duo or Celeron processors, includes a 2.5-inch drive bay and CFast slot, accepts DC power from 16V to 30V, and sports six serial ports, according to the company.

Nexcom's NISE-3142 (pictured) is the successor to earlier systems with the same 10.5 x 7.7 x 3.1 case, such as 2010's NISE 3500, 2009's NISE 3100e and 2006's NISE 3100. Again, it's fanless, accepting either Core 2 Duo P8400 (2.26GHz clock speed) or Celeron 575 (2.0GHz) processors, according to the company.

Its Sept. 23 release wasn't accompanied by a data sheet or product page, but Nexcom says the NISE-3142 is an updated version of the previous NISE-3140, so we've extrapolated from there. One interesting modification is that the NISE-3140 had an (IDE-based) CompactFlash slot, whereas the NISE-3142 gets an (SATA-based) CFast slot.

The NISE-3142 also replaces the NISE-3140's VGA and DVI-D video outputs with dual DVI-D connectors. And it has six serial ports (one RS232/422/485 and five RS232), provided via two DB9 connectors and one DB44 connector, as seen below.

According to Nexcom, the NISE-3142 also has two gigabit Ethernet connectors, plus six USB 2.0 ports (two on the front panel, four on the rear). Memory is expandable up to 4GB via two DIMM slots, and there's a bay for a 2.5-inch, SATA hard disk drive, the company adds.

The NISE-3142 includes a single PCI expansion slot, but Nexcom also lists a NISE-3142P2 version, with two PCI slots, and a NISE-3142M2E version, with one PCI slot and one PCI Express x1 slot. Also cited is a "medical grade" NISE-3142M, though no detail was provided on what earns it this qualification.

Nexcom says the NISE-3142 operates on DC power inputs ranging from 16V to 30V, and is suitable for applications such as factory automation and digital signage. An optional NISKIG 120 "power ignition module" makes it suitable for in-vehicle applications too, the company adds.
