Chapter 1 Introduction
About This Manual
Throughout this manual you will see icons on the left margin that denote
either Notes or Cautions as outlined below:
Denotes a Caution or Warning. Pay particular attention to
these, as they will prevent you from harming your system
or DigitalDoc5.
Denotes a Note or Tip. These will give you Tips, Notes or
Good Ideas on how to use and set up your DigitalDoc5
more effectively.
The DigitalDoc5
The new generation DigitalDoc5 thermal sensor is the only automatic
monitor of system temperature, fans, and voltage, simultaneously
scanning eight temperature settings and eight fans, as well as the stability
of the +5 or +12 VDC power supply. In addition, you can set the cycle
time to automatically scan each channel's temperature, fan speed and
rotation status. If the temperature rises to the adjustable set-point value,
the fan for that channel will automatically switch on to pull cool air in or
hot air out, effectively lowering the temperature. In the event that the
temperature continues to rise (exceeding 5 C above the set-point), a
warning beeper will be activated. This alerts the user or MIS, to use this
additional time to decrease the loading of the computer equipment that is
causing the excessive temperature problem, thus preventing valuable
data loss and system damage.
This manual is arranged in a logical progression from installing your
DigitalDoc5 to setting it up and finally using it.

Features
• Monitoring temperature range: 0°-100° degrees C (32°-212° F).
User can adjust the set-point value. If the temperature reaches the
set-point, the fan for that channel is automatically activated; after the
fan has been turned on, if the temperature continues to rise an
additional 5°C above the set-point, the unit will issue a warning signal.
• Monitors both +5 and +12 VDC power sources: the power
tolerance warning can be set to any of four values: 5%, 10%, 15%,
and 20%. If this tolerance is broken either by a voltage slump or a
voltage spike the unit will warn the user.
• No batteries required: connects directly to your equipment's +12
VDC power source. You do not need additional batteries to operate
this unit.
• LCD back-lighting function: convenient for diagnostic work and for
adjusting the settings. The back-lighting function can be set to be
“always on”, or to just be on when in use, reducing electricity use and
environmental energy needs.
• Uses EEPROM memory chip to save all settings. When equipment
is turned on, there is no need to re-enter settings.
• Unit easily installs in any 5.25" opening; takes up minimal space,
and provides an option for hard drives cooling.
• Supports eight fans while simultaneously monitoring fan speed
(rpm). Can be used with any +12 VDC fan with maximum start-up
current requirement of up to 1000 mA.
• All connected fans can be turned on when the power is turned on,
or only a portion of them. This reduces energy consumption and
creates a quieter work environment.
• Comes with override fan control function. User can turn on fan at
any time with the FORCE function, without having to wait for the
temperature to rise.
• The unit has four or eight set-point selection (depending on the
user's requirements).
• Facilitates objective scientific analysis or MIS investigation; quickly
clarifies problem source in equipment or system.
• Especially suitable for DIY applications, the DigitalDoc5 can be
used with RAID towers, servers, Industrial PCs, and personal
computers.

Chapter 2 Installation
Planning Your Setup
The DigitalDoc5 comes with up to 8 Temperature Sensors (Thermistors)
and can control and monitor the speed (RPM) of up to 8 fans. The
DigitalDoc5 can control all kinds of +12 VDC fans whose current
requirements do not exceed 1000mA or 1 Amp, regardless of whether the
fan has a 2-pin or 3-pin connector. In order to use the Fan Speed (RPM)
Monitoring function, your fan must have an RPM Sensing Control, usually
identifiable by a Yellow wire on a 3-pin connector. Please take note if
you are hooking up a fan which has no RPM Sensing (2-pin ) as you
will have to Disable that fan's monitoring function in the
DigitalDoc5's Set-Up Mode (Described later in Chapter 3). You can use
the Printable Worksheet in Chapter 5 to record which fans have RPM
Sensing and which do not.
The fans are controlled by either Temperature Set-Points (a temperature
you set at which the fan will come on) or manually, by setting the fan to
always be on. A Temperature Set-Point is reached when its' Temperature
Sensor (Thermistor) hits the Temperature you set for that Sensor. This is
all done through the Set-Up Mode, which will be explained in detail in
Chapter 3 Setting Up Your DigitalDoc5.
Before you begin installing your DigitalDoc5 you may want to plan how
you are going to set up your system. Since each Temperature Sensor has
a corresponding fan, you will want to match them up so if a Temperature
Sensor hits your Temperature Set-Point the corresponding fan will come
on. Here is an example of how you would set up one of your fans and
Temperature Sensor:
Example: Assume you have a Video Card Cooler (a fan that sits atop
your Video Card to cool down its' chipset). You attach the Number 2
Temperature Sensor to your Video Card's Heatsink to monitor the
Heatsink's Temperature. You would then plug your Video Card Cooler's
fan into the Number 2 fan Connector on the DigitalDoc5 and set the
DigitalDoc5 to turn that fan on when the Number 2 Temperature Sensor
hits, say 40 degrees Celsius.
You would repeat this for as many fans and Temperature Sensors as you
are going to use. You may want to route one Temperature Sensor outside
your case to record the room's ambient temperature. This will give you a
good idea of your cooling setup's effectiveness. There is a at the end of
this manual a Table in which you can record where you put your
Temperature Sensors and which fans are connected to which DigitalDoc5
fan Connectors. This will be useful once you close up your computer
case, as you will not be able to see where everything is. It is highly
recommended that you fill out the worksheet, even before you install the
DigitalDoc5 as noted above.
Tip: It is a good idea to
mark each end of all your
Temperature Sensors with
the number of that
Sensor's Channel. This
way if you ever have to
disconnect either side you
will know which Sensor
goes with which Channel
without following the lines
through your system.

7
Installing The DigitalDoc5
The Temperature Sensors
There are two types of Temperature Sensors included with your
DigitalDoc5. The flat type, Fig. 2-1, is good for attaching to any flat
surfaces, such as the motherboard chip set, See Fig. 2-4. The bulb type,
Fig. 2-2, can be used in many ways. You can insert it in between the fins
of a heatsink, leave it in an open area to monitor the surrounding ambient
temperature, or also attach it to a flat surface such as the top of your hard
drive. Use the included Thermal Tape, Fig. 2-3, to attach the sensors to
heat sources.
If you followed the tip of marking each sensor's channel, attach it to the
corresponding Two-Pin Connector on the back of the DigitalDoc5
Shown in Fig. 2-5. Note: Either orientation can be used when connecting
the sensors.
Tip:It is recommended to
first attach your sensors to
their pins Fig. 2-5, feed
them through the external
bay, put the DigitalDoc5
temporarily in the bay,
hook the fans and power
cable up, install it in the
bay using the screws that
came in the box and then
finally to attach the
sensors to their heat
sources and/ or locations.
Warning:Never put a
temperature sensor in
between a processor or
silicon chip and a
heatsink. While this may
give you a more accurate
temperature, it will
decrease the ability of the
heatsink to cool down
your chip.

8
Installing Your DigitalDoc5
Connecting The Fans
Each Fan Connector has three wires, red, black and yellow. The red wire
is the power (+ 12VDC), black is the ground (GND) and the yellow is the
RPM
Speed. Each DigitalDoc5 comes with a 40 x 40 mm fan, designated at the
factory as Fan 1. It is connected to the number one temperature sensor.
All other Fan Connectors are clearly marked as Fan 2, Fan 3, Fan 4...
Although there should be only one way to attach each Fan Connector to
each Fan, make sure the wires are matched up correctly. Unless you are
connecting a 2-pin fan, red should match with red, black with black and
yellow with yellow. If you are using a 2-pin fan the yellow wire will not be
used.
The Power Cable
The DigitalDoc5 Thermal Sensor is designed to connect to a +12 VDC
power - source-no batteries are required. One end of the power source
cable supplied with the unit is a standard 4-pin female connector; it is
designed so that there is no way to incorrectly insert it. The connector at
the other end connects to the DigitalDoc5 PCB at location marked
PWR_CON. This connector is also designed so that is can only be
connected the correct way. Following is a drawing of the power cable:
Install The DigitalDoc5 In An Open 5 1/ 4" Bay
After you attach the power cable you can now mount the DigitalDoc5 in
any open External 5 1/ 4" Bay. Install it as you would any 5 1/ 4" device
with the screws provided in the package.
Tip:Your DigitalDoc5 also
acts as a Hard Drive
cooler. You can mount a 5
1/ 4" hard drive assembly
right on to the DigitalDoc5
bracket. You don't lose a
bay and cool your hard
drive off. Cool!

We are now going to set up the DigitalDoc5 and get it ready for use. But
first let's go over the Button Functions as displayed in Fig. 2 as they
relate to SetUp:
2-1 Up Button: The Up button will change the Temperature Set-Points
and Voltage Tolerance settings as well as, let you choose different
options.
2-2 Down Button: Same as Up only Down.
2-3 Set Button: This is the button we need to use now to set up the
DigitalDoc5.
2-4 Reset Button: This will set all the settings back to the default factory
values.
2-5 Force Button: This will force all your fans to come on.
2-6 Scan Button: Used to go into Scan Mode... More on that later.
Figures 1 & 2 will be fully explained in Chapter 4 Using Your DigitalDoc5
Note: The display area
shown in Fig. 1 features a
back-light LCD. The
backlight can be set to
turn off when not in use to
conserve energy, or you
can have it lit all the time.

10
Factory Presets
Before the DigitalDoc5 leaves the factory the values are set to the
following:
• All Temperature Set-Points are set to 50° C.
• Only Fan number 1 has been "turned on" and its' RPM monitoring
enabled. We will set all the other fans during this set up
procedure.
• The power tolerance warning range is set at +5% (or +0.25 V) for
+5 VDC, and for +12 VDC, the range is +0.6 V.
If you make a mistake when setting the system values, you can change
all the values back to those of the factory settings. This is accomplished
by pressing the SET button before the power is turned on. After this, turn
the power on again and wait until you hear the sound of two beeps, which
shows that the resetting in complete. Or when the power is on, press the
RESET button, then press the SET button; afterwards press the RESET
button again, and the two beeps indicate that the resetting is complete.
Getting Started
To begin the set up procedure you need to press the Set Button on your
DigitalDoc5. This will bring you into Set-Up mode and will allow you to
change all the settings according to your setup. At any time, if you do not
press a button within 5 seconds, the DigitalDoc5 will return to Normal
Operating Mode and you will have to restart the set up procedure by
pressing the Set Button again.
Here is a basic flow chart outlining the steps involved in setting up your
DigitalDoc5. Later in this chapter we will go through these Step-By-Step.
Each time you press the Set Button you will continue on to the next
setting. You will use the Up and Down Buttons to change the settings
such as Fan On-Off, RPM Sensing Enabled or Disabled, Temperature
Levels and Power Tolerance Levels.
A) Celsius (C) or Fahrenheit (F) temperature unit selection.
B) Individual channel set-point selection, starting with the
temperature setting for channel 1 (CH1) and proceeding through
the set-points of all channels.
C) Fan rotation monitoring and rotation control setting, starting from
fan 1 (FAN1). When initially setting the fan rotation control
function, the screen will display either [En] or [Dis].
Note: [En] indicates that the fan speed monitoring function is on,
i.e. enabled; [Dis] indicates that it is off for this fan, i.e. disabled.
Next is the override fan control, with the display showing either
[On] or [Off]. [On] indicates that the override function is on (i. e.,
the fan is turned on whenever the power is turned on to the unit).
Tip: You can leave Set-
Up Mode at any time by
not pressing any button
for 5 seconds. All values
will automatically be
saved.
Note: Have your
Printable Worksheet in
front of you when you go
through the set up
procedure. It will help you
throughout the set up
procedure by showing you
which fans are RPM
Sensing or not.

11
D) Four levels of +5 VDC power tolerance range settings: 0.25, 0.5,
0.75, and 1.0 V.
E) Four levels of +12 VDC power tolerance range settings: 0.6, 1.2,
1.8, and 2.4 V.
Step-By-Step Instructions
The first press of the Set Button will present you with the following
display - Fig. 3-1. This means that all temperatures shown on the
DigitalDoc5 will appear in Celsius. Each time you want to move to the
next function press the Set Button.
Step 1: Changing Temp. Units From Celsius (°C) to Fahrenheit (°F)
The LCD will show a flashing °C Fig. 3-2 or °F Fig. 3-3 symbol. Press
the Up or Down Button once to change the units.
Step 2: Temperature Set-Points
Press the Set Button again to start selecting the Temperature Set-Point
values. These are the temperatures you set at which the fans will come
on. Each time you press the Set Button the next channel (CH1.... CH8)
will be displayed. Use the Up and Down Buttons to change the
temperature values.
Tip: Pressing the Scan
Button during Set-Up
Mode toggles the Back-
light Function On and
Off. When it is set to off it
will only turn on when in
use.
Tip: If you hold down a
button and do not release
it, the value quickly
increases or decreases.
When you reach the
desired set-point value,
release the button.

12
Fig. 3-4 shows Channel 1 (CH 1) 's Temperature Set-Point is set to 50°
Celsius. Note: The range of temperature values for Celsius is 0° to 100°
C; and for Fahrenheit is 32° to 212° F.
Step 3: Fan Monitoring and Rotation Settings
Pressing the Set Button again will take you through the Fan Monitoring
and Rotation Settings procedure. Each fan's setting includes fan speed
monitoring and fan override rotation control.
A) The fan speed monitoring function can be turned on with [En] Fig. 3-5,
and off with [Dis] Fig. 3-6. Use the Up and Down buttons to change the
setting from Enabled [EN] to Disabled [DIS], and remember do not Enable
a fan's monitoring function if it does not have an RPM Sensing Control
(check your worksheet). Doing so will result in an alarm being set off
because the DigitalDoc5 thinks the fan is not working or its' RPM has
dropped below 500.
B) Pressing the Set Button again takes you to that fan's rotation or
override setting. The LCD displaying [On] Fig. 3-7 or [Off ] Fig. 3-8
indicates that you can set the fan's rotation control; [On] which forces the
fan on all the time, while [Off] turns the fan off, allowing this fan to be
controlled by your Temperature Set-Point. Again use the Up and Down
Buttons to change the setting from [On] to [Off ]. Note: If you want this
fan to turn on every time you turn on the computer, then you must set this
item to [On], forcing the fan to turn on.
Warning: The rotation
monitoring function
depends on the rotation
signal put out by the fan. If
you use common 2-pin
fans or fans with the
signal disabled, then you
must turn off the rotation
monitoring function by
selecting [dIS], or a
warning alarm will sound.
Warning: If you connect
your main processor's fan
to the DigitalDoc5 you
should set that fan's
Rotation setting to [ON].
This way the fan will be
forced on every time you
use your computer. You
may want to do this for all
your vital fans.

13
C) Pressing the Set Button again will move you to your next fan. Repeat
steps A and B for as many fans as you have connected.
Step 4: Power Tolerance Settings
Pressing the Set Button again will now take you to the final procedure,
the Power Tolerance Settings. There are two settings, the +5 VDC
Tolerance Fig. 3-9 and +12 VDC Tolerance Fig. 3-10. Use the Up and
Down Buttons to cycle through the range of values.
A) Set the +5 VDC tolerance to one of the four range values: +0.25, +0.5,
+0.75, and +1.0 V. Note: For most electronic circuits using +5 VDC
working power with a highly stable source, we suggest that the tolerance
be set at 0.25 V (5%).
B) Press the Set Button again to reach the +12 VDC tolerance setting.
C) Set the +12 VDC tolerance to one of the four range values: +0.60,
+1.20, +1.80, and +2.40 V.
Note: Most +12 VDC sources are used for hard disk drive and CD drive
motors, or for fans. When no devices are running, the power needs are
not excessive, and surges in the power will not be too great. But when the
loading is higher, the system can generate large changes in the power
source, especially evident for example, when a CD drive spins-up.
Outside a certain range in the power supply, your system may experience
errors in operation, so you must pay attention to the power tolerance
range setting.
Finally, pressing Set Button again will bring you out of Set-Up Mode and
return you back to Normal Operating Mode.

2-6 Scan Button: Used for entering Scan Mode; depends on the
indicated sensor channel and each fan speed. If you're in Set-Up Mode,
this button is used to turn on or off the continuous LCD back-lighting
function.

16
Three Modes Of Operation
Your DigitalDoc5 has three basic modes, Set-Up Mode, Normal
Operating Mode, and Scan Mode.
Set-Up Mode
Set-Up Mode can be reached any time by pressing the Set Button. Since
we've already covered Set-Up Mode, we'll refer you back to Chapter 3,
Setting Up Your DigitalDoc5
Normal Operating Mode
Normal Operating Mode is the mode you will use most often and also the
mode the DigitalDoc5 reverts back to from Set-Up and Scan Modes.
During normal operation your DigitalDoc5 displays what fans are currently
running (1-4) and the current Voltage readings (1-5). In Normal Operating
Mode the DigitalDoc5 scans each Temperature Sensor (Channel) and
displays it for 5 seconds, completing a cycle every 40 seconds. If you
press the Up or Down Buttons the DigitalDoc5 will display the next
Temperature Setting value. As it cycles through all 8 Temperature
Sensors (Channels), the Fan Rotation (1-8) status icon will spin if the
corresponding fan is currently running.
Scan Mode
Scan Mode Fig. 3 is reached by pressing the Scan Button on your
DigitalDoc5.
Tip: While in Normal
Operating Mode, pressing
the Up or Down Button
will quickly take you to
and display the next
Channel.
Note: A "Channel" refers
to both the Current
Temperature Sensor and
also its' corresponding
fan. For Example, in Fig.
1, it is currently displaying
Channel 4 (CH 4) and the
number 4 Temperature
Sensor's reading is 26.3
degrees Celsius.. It is also
showing the current status
of Fan number 4 (1-8).

17
In Scan Mode the DigitalDoc5 scans through all your Temperature
Sensor values and Fan Speed (RPM) for each fan. In Fig. 3 it is currently
displaying the RPM reading for Fan Number 2. It will first cycle through all
the temperatures of each Temperature Sensor (Channel). It displays each
temperature reading for 5 seconds and then cycles to the next Channel.
After it completes all 8-temperature readings (a 40 second cycle) it then
begins showing your RPM Speed readings for each fan. It displays each
fan's RPM speed for 5 seconds and then cycles to the next Channel.
After it completes all 8 channels it returns the DigitalDoc5 to Normal
Operating Mode. To begin another Scan Cycle press the Scan Button
again.
Alarms And Warnings
Excessive Temperature Warning
1) When the temperature exceeds the set-point value, the system will
activate a warning beeper and the corresponding channel number will
flash.
2) Pressing any button turns off the warning beeper; at which time the
system will record the warning temperature level.
3) After the warning beeper has been turned off, if the temperature in that
channel continues to rise another 5 C, then the system will activate the
warning beeper a second time.
4) If the warning beeper is turned off a second time, then the system will
not issue another warning message for that channel, unless the
temperature drops back below the set-point, at which time the function is
again operable.
Fan Problem Indicator
1) Fan problem monitoring is limited to the speed function of active fans.
2) When the fan is being monitored, and a discrepancy is discovered in
the fan speed, or the speed drops below 500 rpm, the system will activate
a warning beeper.
3) When the override fan control is in operation, if the fan monitor is not
connected, or if the fan has a 2-pin connector, the system will issue a
warning beeper. Therefore, if no fan is connected or you are using a 2-pin
fan, please turn that fan's monitoring function to [Dis], and there will be no
error in operation.
4) You can press any button to turn off the fan error warning beeper.
Note: It takes
approximately 80 seconds
to scan all 8 Temperature
Sensors and 8 Fan RPM
Speed channels. If a fan
is not running, then 0
RPM will show for that
Channel.
Tip: If an Alarm is
sounding you can press
any button on the
DigitalDoc5 to turn it off at
any time.

18
Power Tolerance Warning
1) When the +5 or +12 VDC power source exceeds the setting for
tolerance warning range.
2) For the +5 VDC standard and a setting of 0.25 V, if the power drops
below 4.75 V or exceeds 5.25 V, a warning beeper will sound.
3) For the +12 VDC standard and a setting of 0.6 V, if the power drops
below 11.4 V or exceeds 12.6 V, a warning beeper will sound.

Frequently Asked Questions
Q1. Why would I need a DigitalDoc5? A –The DigitalDoc5 is similar in
function to that of the temperature gauge in any automobile. It monitors
the temperature levels of up to four units per monitor. The temperature
gauge in a car monitors the heat in the engine. It notifies the driver of
overheating, and if the temperature continues to increase, will initiate the
engine's cooling fan. If the driver does not have this warning, the engine
will be damaged beyond repair. Likewise, the DigitalDoc5 monitors the
temperature of up to eight different units per monitor, and safeguards the
system from overheating, thus protecting your valuable data and
hardware.
Q2. What is the temperature range for the DigitalDoc5? A–The
temperature is displayed in Celsius or Fahrenheit degrees, in ranges of 0°
C -100° C or 32° F-212° F. It is accurate to ± one degree.
Q3. Does the DigitalDoc5 occupy a 5.25" single-slot? A– No, it will
not take up any extra space. The DigitalDoc5 is merely a front panel, with
a mounting bracket for 3.5" hard drive.
Q4. Does the DigitalDoc5 require a battery? A– The DigitalDoc5 does
not require a battery. This battery-free device receives power directly from
the system, however the settings are memorized even when the
computer is shut off.
Q5. How many fans can the DigitalDoc5 monitor and control? A–
The DigitalDoc5 can control up to four can control up to 8 12 V fans,
which are activated when the temperature exceeds the pre-set level.
Q6. Can I keep the front-panel fans running continuously? A– Yes,
though the fans normally are activated at a pre-set level, there is an
option that will allow ALL fans to run continuously.
Q7. Will the front-panel fans collect a great amount of dust? A– No,
there is a filter in front of the fan that prevents the collection of dust. It can
be easily removed and cleaned.
Q8. What is the difference between DigitalDoc5 and a "baycooler"?
A– A "baycooler" is a front panel with a few fans that run continuously
and are relatively noisy. It is simple in design, and easily copied by
competitors. It also does not have a temperature gauge and temperature
pre-set level, which are found in the DigitalDoc5. The DigitalDoc5 also
has a sophisticated design, making it difficult for competitors to imitate it.
Q9. What is the difference between DigitalDoc5 and the
CompuNurse? A– The CompuNurse has an LCD display that shows the
temperature of one unit in the device. The DigitalDoc5 shows the
temperature levels of up to eight units. The CompuNurse also does not
have temperature pre-set levels, monitor and control capabilities of the
fans, and warning beep signals, all found in the DigitalDoc5.
