Analog Inputs
The card supports up to sixteen software-selectable analog input channels. You
may program the input voltage range for -5 to +5 volts, -10 to +10 volts, or 0 to
+10 volts.
Your Smart Trac DM6420 Multi I/O may be programmed with binary gains of
1, 2, 4, and 8, to amplify lower level signals to more closely match the module’s
input ranges (see Table 1). Overvoltage protection to ±12 volts is provided at the
inputs.
Table 1. Input signal amplification for selected input ranges.

0-10V 0-10V 0-5V 0-2.5V 0-1.25V
The 12-bit successive approximation A/D converter accurately digitizes
dynamic input voltages in 2 micro-seconds, for a maximum throughput rate of
500 kHz. The converter IC contains a sample-and-hold amplifier, a 12-bit A/D
converter, a 2.4-volt reference, a clock, and a digital interface to provide a
complete A/D conversion function on a single chip. Conversions are controlled
by Smart Trac software commands.
Two independent 12-bit analog output channels are included on the Smart Trac
DM6420 Multi I/O Card. The analog outputs are generated by two 12-bit D/A
converters with independent jumper-selectable output ranges of ±5, 0 to +5, or 0
to +10 volts. The 10-volt ranges have a resolution of 2.44 millivolts, and the 5volt range has a resolution of 1.22 millivolts.
Data may be transferred between your Smart Trac DM6420 Multi I/O card and
external devices using sixteen (16) digital I/O points. Eight of these points are
bit programmable and eight are byte, or port, programmable.
Maximum Magnitude of Input Signal
• Port 0 provides eight bit programmable points which can be
independently set for input or output.
• Port 1 can be programmed as an 8-bit input or output port.

Unpacking
Electrostatic
Discharge (ESD)
Procedures
Unpacking Procedure
WARNING WARNING -- ESD ESD
Keep electronic circuit boards in Electrostatic Discharge (ESD)
protective bags when not being handled. Use proper ESD
procedures (including an ESD wrist strap) when handling circuit
boards. Failure to comply may result in damage to equipment.
When working with an electrostatic discharge (ESD) sensitive device, you
should be grounded at all times. The easiest and most common way to provide
this ground is to use an approved ESD wrist strap. The strap is secured to your
wrist with a wire attached to the strap and clipped or taped to the chassis of the
unit being worked on. Any static is dissipated through the wire to ground,
greatly reducing the possibility of damage to the device.
It is a good idea to touch the chassis with your finger before handling any
electrostatic sensitive device. Any static electricity will be discharged to chassis
ground and will not be transferred to the device.
Always store devices (cards, other electronic components) in ESD protective
bags when not being handled.
Remove the protective shipping and packing material from the card. Ensure
contact wedges and other shipping devices have been removed.
Installing the Smart Trac DM6420
Multi I/O Card
The Smart Trac DM6420 Multi I/O Card is PC/104 compatible, so it may be
positioned as one of two PC/104 option cards at the very top of the Smart Trac
card stack, just above the Ethernet card or another PC/104 option card.

Smart Trac DM6420 Multi I/O Card
When using the differential mode:
Connecting Analog Outputs
To make an Analog Output connection, for each of the two D/A outputs:
1. Install a 10 kilohm resistor pack at location RN2 on the module to
provide a reference to ground for signal sources without a separate
ground reference.
2. Connect the high side of the analog input to the selected analog input
channel, AIN1+ through AIN8+,
3. Connect the low side of the input to the corresponding AIN- pin.
4. For signal sources with a separate ground reference, connect the ground
from the signal source to an ANALOG GND (pins 18 and 20-22 on
CN3). Figure 7 shows how these connections are made.
1. Connect the high side of the device receiving the output to the AOUT
channel (CN3-17 or CN3-19).
2. Connect the low side of the device to an ANALOG GND (CN3-18 or
CN3-20).
Connecting Digital I/O
Digital connections consist of two eight-bit ports. Port 0 direction (Input or
Output) is bit-programmable. Port 1 direction (Input or Output) is byte (port)
programmable.
To make a Digital I/O connection:
1. Connect the high side of an external signal source or destination device
to the appropriate signal pin on the I/O connector.
2. Connected the low side to any DIGITAL GND.

Testing Card Installation
Testing the Installed Card
Once installed, you may test your Smart Trac DM6420 Multi I/O card by
reading values at I/O points on the card.
Using a digital voltmeter or multimeter, measure the values at each of
Input/Output CN3 connector terminals to see that inputs and outputs are active
(See Figure 5). The readings should be the values defined by the CN3 connector
and the gains used by the application program.
Run the application software to see if the drive is behaving properly.

NOTE: The Smart Trac PG card requires unique handling. Wedge the extracting
tool between the PG card and the CPU card. The area between the terminal strip
on the CPU card and the serial numbered edge of the PG card can be lifted first,
then the opposite side (nearest TB1) on the PG card). Alternate sides until the
card is free of the CPU card.
10. To remove the Smart Trac CPU card:
26 •• Appendix C – Removing the Smart Trac Card Stack Technical Manual
SMART TRAC DM6420 Multi I/O Card
• Disconnect the card at the 2CN connector on the CPU card.
• The CPU card is secured with three plastic standoffs with spring-
loaded clips on the end. Squeeze the top of the standoffs (the clips)
with the special cylindrical removal tool, your fingers or needlenosed pliers and lift the CPU card from the Smart Trac Inverter
Control Card.
You have removed the entire card stack. The inverter card, considered part of
the drive, is in clear view.

operation
Operation in which a two-wire signal references the positive of the pair to the
minus of the pair instead of to ground. The minus of the pair is implied to be
ground.
An embedded PC bus standard. The standard defines the mechanical size of a
self-stacking bus. Also an IEEE draft standard, called the P996.1 Standard for
Compact Embedded PC Modules, PC/104 Specification, Version 2.1, July 1994,
