DM5210 analog input module i-3 RTD Embedded Technologies, Inc.
The DM210 and DM5210 dataModule®medium speed analog input modules 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 210/5210 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,
• 20 TTL/CMOS 8255 based programmable digital I/O (16 at I/O connector, 4 at on-board pads),
• Three independent 16-bit, 8-MHz timer/counters,
• +5 volt only operation (DM5210),
• BASIC and Turbo C source code; diagnostics program.
Note that the difference between the DM210 and DM5210 is the power supply requirements: the DM210
requires ±12 and +5 volt power sources and the DM5210 requires a +5 volt source. The following paragraphs briefly
describe the major functions of the module. A detailed discussion of module functions is included in subsequent
chapters.
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 protection to ±35 volts is
provided at the inputs. A/D conversions are performed by a 12-bit successive approximation 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 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 210/5210 has 20 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 are provided
by the on-board 8255 programmable peripheral interface (PPI) chip. Sixteen of the lines are brought out to the I/O
connector and four are available at a set of on-board pads located near the edge of the module for easy access. Pads
for installing and activating pull-up or pull-down resistors are included on the module for the 16 lines brought out to
the I/O connector. Installation procedures are given at the end of Chapter 1, Module Settings.

CHAPTER 1
MODULE SETTINGS
The 210/5210 has jumper and switch settings you can change if
necessary for your application. The module is factory-configured
with the settings listed in Table 1-1 and shown on the module
diagram at the beginning of this chapter. Should you need to
change these settings, use these easy-to-follow instructions before
you install the module in your system.
By installing resistor packs and soldering jumpers in the de-
sired locations in the associated pads as described near the end of
the chapter, you can configure 16 of your digital I/O lines to be
pulled up or pulled down.
The final section describes how to install two resistors and a
trimpot to set the resistor configurable gain to the value required
for your application. A pad for installing a capacitor is also in-
cluded in the gain circuitry for creating a low-pass filter.

Factory Setting Fig. 1-2b: Interrupt Source
Connected to IRQ3
Fig. 1-2 — Interrupt Channel Jumper, P3
P3 — Interrupt Channel Select (Factory Setting: Interrupt Channels Disabled; G Connected)
This header connector, shown in Figure 1-2, lets you connect any one of the three interrupt sources on P7 to an
interrupt channel, IRQ2 (highest priority channel) through IRQ7 (lowest priority channel). IRQ2 is the righttmost
channel and IRQ7 is the leftmost channel (next to last pair of pins). To activate a channel, you must install a jumper
vertically across the desired IRQ channel’s pair of pins. Figure 1-2a shows the factory setting; Figure 1-2b shows the
interrupt source connected to IRQ3.
This module supports an interrupt sharing mode where the pins labeled G, connect a 1 kilohm pull-down resistor
to the output of a high-impedance tri-state driver which carries the interrupt request signal. This pull-down resistor
pulls the interrupt request line low whenever interrupts are not active. Whenever an interrupt request is made, the tri-
state buffer is enabled, forcing the output high and generating an interrupt. You can monitor the interrupt status
through bit 1 in the status word (I/O address location BA + 10). After the interrupt has been serviced, the reset
command returns the IRQ line low, disabling the tri-state buffer, and pulling the output low again. Figure 1-3 shows
this circuit. Because the interrupt request line is pulled low only by the pull-down resistor, you can have two or more
modules which share the same IRQ channel. You can tell which module issued the interrupt request by monitoring
each module’s IRQ status bit. If you are not planning on sharing interrupts or if you are not sure that your CPU
supports interrupt sharing, it is best to disable this feature and use the interrupts in the normal mode. This will insure
compatibility with all CPUs. See chapter 4 for details on disabling the interrupt sharing circuit.
NOTE: When you use multiple modules that share the same interrupt, only one module should have the G
jumper installed. The rest should be disconnected. Whenever you operate a single module, the G jumper should be
installed. Whenever you operate the module with interrupt sharing disabled, the G jumper should be removed.

This header connector, shown in Figure 1-4, lets you select the clock sources for the 8254 timer/counters, TC0,
TC1, and TC2. The factory setting cascades all three timer/counters, with the clock source for TC0 being the on-
board 8 MHz oscillator, the output of TC0 providing the clock for TC1, and the output of TC1 providing the clock
for TC2. You can connect any or all of the sources to an external clock input through the P2 I/O connector, or you
can set TC1 and TC2 to be clocked by the 8 MHz oscillator. Figure 1-5 shows a block diagram of the timer/counter
circuitry to help you with these connections.
NOTE: When installing jumpers on this header, make sure that only one jumper is installed in each group of
two or three CLK pins.

P5 — Analog Input Voltage Range (Factory Setting: 10V)
This header connector, shown in Figure 1-6, lets you select the analog input voltage range. The range is set by
placing the jumper across the pair of pins labeled 10V, giving you a 10 volt range, or by placing the jumper across
the pins labeled 20V, giving you a 20-volt range. Note that when you place a jumper across 20V, you must place the
jumper on P6 across the +/- pins (bipolar range of -10 to +10 volts). The + setting on P6 cannot be used with 20V.
P6 — Analog Input Voltage Polarity (Factory Setting: +/- (Bipolar))
This header connector, shown in Figure 1-6, lets you select the analog input polarity by placing a jumper across
the pins labeled + for 0 to +10 volts, or +/- for ±5 or ±10 volts. Note that when you place a jumper across 20V on P5,
you must place the P6 jumper across +/- (±10 volts). The + setting cannot be used with the 20 volt input range.
Figure 1-6 shows the three possible input voltage configurations for P5 and P6.

This header connector, shown in Figure 1-7, lets you select any one of three signal sources for use in generating
an interrupt. An interrupt source is chosen by placing a jumper across the desired pair of pins. The interrupt sources
available are the A/D end-of-convert (EOC), the output of timer/counter 2 (OT2), and timer/counter external clock 2
(EC2). The interrupt channel for the selected source is set on P3.

DM5210 analog input module 1-7 RTD Embedded Technologies, Inc.
S1 — Base Address (Factory Setting: 300 hex (768 decimal))
One of the most common causes of failure when you are first trying your module is address contention. Some of
your computer’s I/O space is already occupied by internal I/O and other peripherals. When the 210/5210 attempts to
use I/O address locations already used by another device, contention results and the module does not work.
To avoid this problem, the 210/5210 has an easily accessible DIP switch, S1, which lets you select any one of 32
starting addresses in the computer’s I/O. Should the factory setting of 300 hex (768 decimal) be unsuitable for your
system, you can select a different base address simply by setting the switches to any one of the values listed in Table
1-2. The table shows the switch settings and their corresponding decimal and hexadecimal (in parentheses) values.
Make sure that you verify the order of the switch numbers on the switch (1 through 5) before setting them. When the
switches are pulled forward, they are OPEN, or set to logic 1, as labeled on the DIP switch package. When you set
the base address for your module, record the value in the table inside the back cover. Figure 1-9 shows the DIP
switch set for a base address of 300 hex (768 decimal).
