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.

±5V ±5V ±2.5V ±1.25V ±0.625V
±10V ±10V ±5.0V ±2.50V ±1.25V
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

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.
