New Family of PC/104 16-Bit Analog I/O Modules Excels in Rugged Applications

Diamond Systems DMM-16-AT

Diamond Systems, a leading global supplier of compact,
rugged, I/O-rich embedded computing solutions for real-world applications in a
broad range of markets, unveiled its latest additions to its industry-leading
Diamond-MM family of 16-bit analog I/O modules, DMM-16R-AT and DMM-16RP-AT.
These rugged I/O modules offer 16-channels of 16-bit analog input, 4-channels
of 12-bit analog output and 16 programmable digital I/O lines. The new I/O
modules work with both PC/104 and PC/104-Plus form factors. The built-in
autocalibration feature provides highest measurement accuracy regardless of
time and ambient temperature.

The DMM-16R/RP-AT features top performance and flexibility
at a mid-range price. It has 16 single-ended / 8 differential analog inputs
with both unipolar and bipolar input ranges and programmable gain. It has a
maximum sampling rate of 100KHz, supported by a 512-sample FIFO with a
256-sample threshold for gap-free high-speed A/D sampling. Both single-channel
and multi-channel scan sampling modes are supported. The A/D can be triggered
with a software command, the on-board programmable timer, or an external
signal. All these features give these boards greater adaptability to real world

The DMM-16R-AT is the PC/104 ISA bus version of the product.
The DMM-16RP-AT adds the PCI-104 PCI connector to provide dual ISA and PCI
interface options with automatic bus selection and manual override. Both ISA
and PCI buses offer the same 100KHZ A/D performance.

The DMM-16R/RP-AT modules offer full backward compatibility
with Diamond’s existing DMM-16-AT board in terms of mechanical design,
connector pinout, and software interface, offering customers a cost-reduced
means of extending the lifecycle of their existing applications. Diamond’s
Universal Driver programming library offers full support for these boards
including example programs with source code. A unique graphical control panel
program for Windows and Linux provides instant access to all of the board’s
features and enables quick prototyping and system diagnostics.

These Diamond analog I/O modules were designed for rugged
applications and harsh environments such as mobile, on-vehicle, factory floor
or outdoor applications. Extended temperature operation of -40ºC to +85ºC is
tested and guaranteed. The modules are compatible with MIL-STD-202G shock and
vibration specifications.
