6 module cPCI card
THE UNIVERSAL 78CI is a flexible 6 module, multifunction, single slot CompactPCI card from North Atlantic Industries, designed to replace multi-
ple, independent, specialised, single function cards. The "mother board" has 6 independent module slots each of which can be populated with a function specific module, of which 17 are so far available. The 78C1 cPCI card can include: 10A/D, 10 D/A, 4 Signal Generator, 16 Digital I/O, 16 discrete I/O, 4 Synchro Resolver, 4
LVDT/RVDT and 6 RTD channels.
Extensive diagnostics are provided by the interchangeable multi function design of the 78C1 which is available in both commercial (0°C to +70°C) and severe environmental military(- 40°C to +85°C) temperature ranges, making the board suitable for airborne, shipboard, ground mobile and C3I applications.
Each of the 78C1 functions is programmable at the channel level. Background (BIT) testing is performed on all functions and channels continuously. This testing is totally transparent to the user, requires no programming and does not interfere with the card's normal operation.

1 U monitor drawer
Rittal has introduced a new 482.6 mm (19”) monitor drawer. With just 1 U of height, the monitor drawer may be installed in the minimal of spaces in all 482.6mm (19”) enclosures or cases with a depth of between 500 and 900mm.
applications where the keyor other data entry device may be separately housed (such as in the lid /door of a portable the flip-up monitor leaves to both keyboard and CD-
accommodation below it.
in sheet steel the monitor drawer, which is lockable at the front, is for use in industrial environments. Ease of use is improved by telescopic slides and a flip up 15” TFT display. An integral lock prevents accidental insertion or withdrawal of the monitor.
Connections for video and mains voltage are positioned at the rear. The power supply unit may be switched off separately, allowing zero electricity consumption in standby mode.

Low power 400MHz CPU board
Wordsworth has introduced the 5.25” NOVA-C400 board. It is an all-in-one fanless solution for applications such as embedded hosts in sealed areas, communications products and PCs for vehicles.
The board uses the ultra low voltage (ULV) Celeron 400MHz processor to minimize power consumption. The ULV Celeron 400 typically consumes 5W compared to 23W of the standard Celeron 400.
The board includes an integrated ProSavage VGA controller and supports a 36-bit dual channel for LVDS interface to LCD displays and a DB15 CRT interface connector. There are two Ethernet 10/100Mbps LAN ports, a Compact Flash Type II socket, an AC ’97 compliant audio codec, a watchdog timer, and four inputs and outputs of TTL level digital I/O.”
