3.0 Installation and Operation
1. The Ground Penetrating Radar PC (GPR PC) should be mounted vertically on a wall in
the control cab of the mining machine.
2. With the GPR box turned off, plug in the DC Power cable to the bottom Panel of the GPR
PC Unit. The DC power connector includes a screw-terminal block for easy field
termination. See the attached DC power cord drawing for the cable pin out configuration.
The GPR PC unit requires a +12V DC power source with at least 5 amperes of current
capacity.
3. Run the provided Roof GPR cable and the Distance Wheel cable from the GPR PC to the
location of the Roof GPR and the Distance Wheel. Run the provided Floor GPR cable
from the GPR PC to the Floor GPR unit. The supplied cables feature 20 AWG, 2-pair,
twisted, individually shielded wire.
4. Plug one of the two 256MB USB Flash memory sticks into the USB port located on the
bottom panel of the GPR PC. This USB Flash stick must be plugged in prior to turning
the power on. The USB Flash sticks will be used to transfer the day’s data to a surface
computer for analysis and backup.
5. Push the main power button, located on the bottom panel. The PC should power up and
perform the power on self test, then it will load the Linux operating system and
automatically start the GPR PC data logging and display program. If the PC doesn't start
then refer to the troubleshooting procedure shown in chapter 4.0.
6. The data logging and display software will automatically start after the GPR PC is
powered. The GPR PC logs data to an external USB Flash stick that must be plugged in
prior to powering the GPR PC. Do not remove the USB Flash stick when the GPR PC is
powered as all data on the stick could be lost. A dust resistant connector cover is provided
and should be kept closed at all times to minimize dust entering the connector.
7. The GPR PC Data Recorder software (written by Kosteniuk Consulting Ltd.) has been
installed on the GPR PC. Refer to the GPR PC Data Recorder Software operating manual
for instructions on the proper use of the software.

4.0 Design Details
4.1 Ground Penetrating Radar PC
The GPR PC contains a VIA EPIA series Mini-ITX motherboard, which interfaces with a
separate 800x600 VGA flat-screen monitor equipped with a touch screen. Also mounted in
the enclosure are an ATX power supply, a quadrature-to-RS-232 converter, and a 2.5” hard
drive
4.2.1 Motherboard
The Motherboard is a VIA model EPIA EK 8000. The board features a low-power, fanless
design with a VIA Luke 800 MHz processor, 256 MB of SODIMM RAM, a 2.5" IDE
Notebook Drive with 60GB capacity, 4 COM ports, 1 LPT port, built-in video and sound
interfaces, 4 USB ports and 2 Ethernet ports.
Several computer connections are brought out to the motherboard. These include a female
PS2 bulkhead connector for use with a PS2 keyboard; IP 67 USB connector and an Ethernet
connector all mounted on the bottom panel of the GPR enclosure. Three of the motherboard's
four RS-232 ports are brought out through 9 pin headers located on the board. The one other
RS-232 port is located on the back panel I/O of the motherboard.
4.2.2 Power Supply
Most of the components of the GPR PC have the capability of operating off of 12V DC power
and require a 12 Volt DC supply with a minimum of 5A capacity to operate (see section
3.2.5). A battery backup power supply unit can be purchased from ASI if an adequate supply
is not available, and can handle a wide range of input voltage input in either DC (9-72 Volts)
or AC (88-264 Volts)
The Motherboard and the Hard Drive require ATX power. A 60W Morex 12Volt DC to ATX
power supply with is located in the GPR PC enclosure directly adjacent to the motherboard.
4.2.3 Battery Backup
An American Power Conversion UPS, with 900 VA is provided inside the power supply unit.
The battery will operate the PC for approximately 45 minutes and is used as an uninterruptible
power supply (UPS) in the event of a DC supply power failure. The battery only supplies
power for the panel PC and will not power either of the Noggin GPR units or the distance
wheel encoder. The battery is provided to allow data to be saved prior to the safe power down

of the PC. Power switches from the DC input to the battery automatically. Once DC supply
power is restored the PC will automatically switch back to AC power and then battery will be
charged.
4.2.4 Quadrature to RS-232 Converter
A model AD4-B quadrature to RS-232 adapter is mounted in the GPR PC enclosure. This
unit provides a simple plug-in method for connecting a single-ended quadrature encoder
directly to a RS-232 serial port. The AD4-B contains a 5 VDC power supply for the encoder,
an LS7166 quadrature counter and a microprocessor that provides the serial interface. The
AD4-B is powered from the 12 VDC power supply and requires up to 185mA of supply
current.
4.2.5 Opening the GPR PC Enclosure
CAUTION: LETHAL VOLTAGES ARE PRESENT WITHIN THE GPR PC.
DISCONNECT INPUT POWER BEFORE OPENING THE CABINET.
Under normal operating conditions there is no reason to open the GPR PC enclosure.
However if the enclosure must be opened for checking power supplies or making changes to
the panel PC (for instance replacement of the touch screen) then use the following procedure
to open the enclosure. Photo 1 shows the completed GPR PC. Photo 2 shows the GPR PC
open with the enclosure cover and the attached panel PC lying in front of the main enclosure.

To open the GPR PC enclosure, first disconnect all connections from the outside of the
enclosure (DC power, Roof and Floor GPR cables and the Distance Wheel cable). Ensure that
the input power is disconnected BEFORE opening the cabinet. Loosen the four screws
holding the top cover onto the enclosure base. These screws are captive and it is not
necessary to remove them from the plastic grommets. Once the screws are loose grasp the top
cover and lift it off of the enclosure base and place it face down in front of the enclosure as
shown in Photo 2. Ensure that the area in front of the enclosure is free of tools and other
objects that could damage the touch screen. The cables connecting the PC to the enclosure are
only long enough for the cover to be placed in the position shown in Photo 2. Do not attempt
to place the cover and the PC in any other location as this will put strain on the connections.
If the touchscreen monitor must be removed completely then first disconnect all wires from
the back of the monitor and then loosen the eight M3 screws located around the edges of the
monitor. Once these screws are undone then the enclosure lid can be lifted off of the monitor.

4.2.6 DC Input Power
The GPR PC requires 12 VDC, power with a current rating of at least 5 amperes. A 10-foot
long power cord with a mating 3 pin plug can be attached to the GPR PC. Drawing AS550AE001 is an interconnection diagram for the GPR PC. Within the GPR PC the input line
connects to a 5A Fast Blow fuse and then to a terminal block for distribution, and to a DIN
mount relay which switches power to the monitor, encoder, and Noggin units when the power
switch on the bottom panel is pressed. The output from the switch is brought to a header on
the mother board which also switches on the computer and its power supply. The main power
switch is a momentary contact switch which can be used to cut power to the GPR PC unit, by
holding for 4 seconds.
The DC common wire connects to a similar terminal block. The GPR PC case is
connected to the earth ground shield wire in the cable, via a Phoenix Contact DIN mount
ground block, and grounding distribution lugs. The supplied DC power cord can be replaced
with field wiring if desired. The mating power plug for the DC input connector that is located
on the GPR PC enclosure includes a screw terminal block to make field termination simple.
Drawing AS550A-E004 provides a cable drawing for the DC power cable. If the GPR PC is
being used with the ASI 551B Power Supply, the DC power cable will be captive to the power
supply unit.
