Long Term Reliability and Maintenance Strategy
There are a number of subsystems and features incorporated into the MakoTL to ensure reliable operation and remote
maintenance. The MakoTL system incorporates an embedded microcontroller, henceforth called the Watchdog. The
Watchdog performs various functions including power management, watchdog and A/D conversion. It’s most important
function though is ensuring that the system software continues to function. In the case of a software or operating system
crash, the watchdog will automatically power cycle the system.
Remote access is included with the purchase of the system. Programming and maintenance can be performed remotely
without having to visit the site.
The operating system shipped on the MakoTL system is a customized Windows Embedded 8 build that features a ROM
operating mode. This mode ensures that no changes can be made to the system partition during normal operation. Images
are stored on separate USB storage in a mirrored configuration.
Error reporting and system status can be sent via email.
The system hardware should routinely be checked for cleanliness every 3-6 months depending on the location. Bird
droppings, dust, frequent rain, icy conditions, and salty environments will hasten this requirement. Extension mops can be
purchased at your local hardware store to give you the ability to wipe down the external housings of any debris. Check
screw cage clamp (green pluggable terminal) wiring at least once a year to ensure a tight connection. Check mounting
bracket at least once a year for loose screws, attach points, or safety straps. Adjust as needed. If operating with UPS battery
backup, be sure to follow the manufacturer's recommended battery replacement schedule.
Hardware Components
Embedded x86-64 Computer: This component is what’s called an embedded pc. It utilizes a low power x86-64 dual core 64
bit microprocessor, which runs at 1.33GHz. It is a very low power computer requiring approximately 6w. Systems will come
with 4GB of RAM and two 128GB USB flash drives. The computer has 4 USB ports (2 occupied by flash storage and a third
occupied by the EOS camera, a VGA port and an Ethernet (RJ45 jack).
Watchdog: This is an 8-bit microcontroller. It has 8K programmable flash and executes our custom firmware that performs a
number of low level functions including power management, rebooting, A/D conversions, watchdog, voltage/temperature
monitoring, and wake up alarm for the embedded pc.
Main Board: Our in-house designed and manufactured PCB. It’s approximately 4” x 3” and sits as the base board in the card
stack.
Functional Switches and LED's: There is 1 functional switch on the Main Board. The “on/off” switch is used to tell the
Watchdog that the unit is to be powered on. This is a soft switch and carries no current. There are also 3 LED’s located on
the edge of the circuit card. Watchdog status, PC power, and HDD activity.
Ports and Connectors: All the user accessible ports to connect to the embedded pc are located on the edge of the board.
This includes USB, monitor (VGA HDDB-15), and network (RJ/45). All external connections to the main board are through
pluggable terminal strips. All the connections are labeled for convenience.
