The DM6210 dataModule® medium speed analog input module turn your IBM PC-compatible

cpuModule or other PC/104 computer into a high-performance data acquisition and control system. Ultra-

compact for embedded and portable applications, the DM6210 features:

16 single-ended analog input channels,

12-bit, 20 microsecond A/D converter,

±5, ±10, or 0 to +10 volt analog input range,

Resistor configurable gain,

16 TTL/CMOS programmable digital I/O lines,

Three independent 16-bit, 8-MHz timer/counters,

+5 volt only operation,

BASIC and C source code; diagnostics program.

Analog-to-Digital Conversion

The analog-to-digital (A/D) circuitry receives up to 16 single-ended analog inputs and converts these

inputs into 12-bit digital data words which can then be read and/or transferred to PC memory.

The analog input voltage range is jumper-selectable for bipolar ranges of -5 to +5 volts or -10 to +10

volts, or a unipolar range of 0 to +10 volts. The module is factory set for -5 to +5 volts. Overvoltage protec-

tion to ±35 volts is provided at the inputs. A/D conversions are performed by a 12-bit successive approxima-

tion converter. This high-performance converter and the high-speed sample-and-hold amplifier preceding it

make sure that dynamic input voltages are accurately digitized. The resolution of a 12-bit conversion is

2.4414 millivolts on the -5 to +5 volt range and the maximum throughput is 40,000 samples per second.

The converted data is read and/or transferred to PC memory, one byte at a time, through the PC data bus.

8254 Timer/Counter

An 8254 programmable interval timer contains three 16-bit, 8-MHz timer/counters to support a wide

range of timing and counting functions. The clock, gate and output pins for each of the three timer/counters

are available at the I/O connector.

Digital I/O

The DM6210 has 16 TTL/CMOS-compatible digital I/O lines which can be directly interfaced with

external devices or signals to sense switch closures, trigger digital events, or activate solid-state relays. The

lines can be programmed as inputs or outputs in groups of 4 bits. There is also a special latched input mode

which allows the digital inputs to be latched on an external clock edge for time critical applications. Pads for

installing and activating pull-up or pull-down resistors are included on the module. Installation procedures

are given at the end of Chapter 1, Module Settings.
