1. IMPORTANT SAFE HANDLING INFORMATION
WARNING!
ESD-Sensitive Electronic Equipment
Observe ESD-safe handling procedures when working with this product.
Always use this product in a properly grounded work area and wear
appropriate ESD-preventive clothing and/or accessories.
Always store this product in ESD-protective packaging when not in use.
Safe Handling Precautions
Diamond Systems boards are designed with complex circuitry and electronic components that are ESD
(Electrostatic Discharge)-sensitive. This increases the likelihood of the boards incurring accidental damage during
handling, installation, and connection to other equipment.
It is highly recommended that the following precautionary measures and best practices be observed in sequential
order:
•Wear an anti-static Wristband/Strap or/and an antistatic Lab Coat or/and Rubber-soled shoes.
•Spread anti-static mats over the table or work surface or/and anti-static mats on the floor.
•Unpack components and remove them from their anti-static bags only when they are ready to be
used.
•Avoid ungrounded surfaces such as plastic, carpets, floors, or tables, in the work area.
•Handle boards by the edges and their metal mounting brackets. Avoid touching components on the
boards and the edge connectors that connect to expansion slots.
The following information describes common causes of failure found on boards and components returned to
Diamond Systems for repair. It is provided as a guideline to avoid accidental damage.
ESD Damage: This type of damage is typically impossible to detect because there is no visual sign of failure or
damage. In this type of damage, the board eventually stops functioning because of some defective components.
Usually, the failure can be identified, and the chip can be replaced.
To prevent ESD damage, always follow proper ESD-prevention practices when handling computer boards.
Damage During Handling or Storage: Physical damage on boards also occur due to mishandling. A common
observation is that of a screwdriver slipping on the board during installation, causing a gouge on the PCB surface,
cutting signal traces or damaging components.
Another common observation is damaged board corners, indicating the board was dropped. This may or may not
cause damage to the circuitry, depending on components located near the edges. Most Diamond System boards
are designed with a minimum 25 mils clearance between the board edge and component pad. The Ground/power
planes are located a minimum of 20 mils from the edge to avoid possible shorting from this type of damage.
However, these design rules do not prevent damage in all situations.
Sometimes boards are stored in racks with slots that grip the edge of the board. This is a common practice for
board manufacturers. Though Diamond Systems boards are resilient to damages, the components located close
to the board edges can be damaged or even knocked off the board if the board lies tilted in the rack.
Diamond Systems recommends that all its boards be stored only in individual ESD-safe packaging units. If
multiple boards are stored together, they should be contained in bins with dividers placed between the boards. Do
not pile boards on top of each other or cram too many boards within a small location. This can cause damage to
connector pins or fragile components.

JetBox-FloydSC User Manual rev 0.1 www.diamondsystems.com Page 5
Damage During Installation on a PC/104 Stack: Damage on boards can also occur while installing the board in
a PC/104 Stack A common cause of damage occurs when the connector pins are misaligned with their
corresponding interfaces on the stack.
For example, during installation, if a PC/104 board pin-mapping is misaligned/shifted by 1 row or 1 column, it can
cause the 12V power and Ground signal lines on the bus to contact the wrong pins on the board and damage
components linked to the data bus lines.
Bent Connector Pins: This type of problem can be resolved by re-bending the pins to their original shape using
needle-nose pliers.
The most common cause of a bent connector pin is when the board is pulled off a stack by tugging it at angles
from one end of the connector to the other, to release it off the stack. Tugging the board off the stack in this
manner can bend the pin(s) significantly.
A similar situation can occur when pulling a ribbon cable off a pin header. If the pins are bent too severely,
bending them back can cause them to weaken or break. In this case, the connector must be replaced.
Power Damages: There are various causes of power-specific damages that can occur while handling the board.
Some common causes such as –a metal screwdriver tip slipping, or a screw dropping onto the board while it is
powered-up, causes a short between a power pin and a signal pin on a component.
These faults can cause over-voltage/power supply problems besides other causes described below.
To avoid such damages, assembly operations must be performed when the system is powered off.
Power Supply Wired Backwards: Diamond Systems power supplies and boards are not designed to withstand a
reverse power supply connection. This will destroy almost all ICs connected to the power supply. In this case, the
board will likely be irreparable and must be replaced. A chip destroyed by reverse or excessive power will often
have a visible hole or show some deformation on the surface due to vaporization inside the package.
Overvoltage on Digital I/O Line: If a Digital I/O signal is connected to a voltage above the maximum specified
voltage, the digital circuitry can be damaged. The acceptable voltage range, on most Diamond Systems boards
connected to digital I/O signals is 0-5V, with overvoltage protection up to 5.5V (-0.5 to 5.5V). Overvoltage beyond
this limit can damage the circuitry.
Other considerations are Logic Signals, which are typically generated between 12V to 24V.
If a Digital I/O Line of 12V to 24V is connected to a 5V logic chip, the chip will be damaged, and the damage could
extend to other chips in the circuit.
IMPORTANT! Always check power connections twice before powering up!

2. INTRODUCTION & SYSTEM CONFIGURATIONS
JetBox-FloydSC System Overview
JetBox-FloydSC is a compact Nvidia Jetson AI computing platform ready to deploy. It includes the Jetson Nano or
NX module installed on Diamond Systems FLOYDSC carrier board with a Linux OS installed and preconfigured to
support all the I/Os on FloydSC.
The system is available multiple standard module configurations to meet a range of customer needs. The system
installed with NVIDA Jetson Nano module supports only 1x Ethernet interface while the system when installed with
NVIDIA Jetson Xavier NX module supports 2x Ethernet interfaces.
JetBox-FloydSC features 11-position screw terminal on the front panel to access the Digital I/Os available on the
system. The enclosure is DIN rail mountable or can be used in a "tabletop" scenario.
The system is compatible with both 12V and 24V DC power supplies. A 12VDC universal AC adapter is included
with the system.

3. FUNCTIONAL OVERVIEW
Power Supply Specifications
The JetBox-FloydSC accepts a wide input voltage range of +7V to +24V. Maximum power consumption with
either Nano or NX module installed, and all peripherals operating is 35W. The maximum allowable reflected
ripple, measured at the voltage input connector is 50 mV p-p. The input power is provided via a barrel jack with
5.5mm OD / 2.5mm ID dimensions (tip positive).
USB Ports
The JetBox-FloydSC provides 2x USB 2.0 ports and 1x USB 3.0 port.
1. 2x USB 2.0 ports are available on a vertically stacked dual-port USB 2.0 connector.
2. The upper USB 2.0 port (USB0) can be used for programming during recovery mode.
3. 1x USB 3.0 port terminates on an upright right-angle USB 3.0 connector. This connector also supports
the USB 2.0 protocol.
The USB signals connected to upright USB3.0 connector is optionally connected to expansion connector using 0
Ohm resistors.
Display
The JetBox-FloydSC supports two display options:
1. HDMI 2.0a/b video with audio with both Nano and NX modules.
2. DP 1.4 video, audio supported with NX module only.
The HDMI is terminated on an upright HDMI connector & the DP is terminated on a separate upright DP
connector.
Ethernet Ports
The JetBox-FloydSC is equipped with one or two Gigabit Ethernet ports:
1. (all models) A 10/100/1000 Ethernet port routed from the module.
2. (NX model only) A 10/100/1000 Ethernet port derived from the Intel WGI210IT/Intel I210 PCIe Ethernet
controller when used with Xavier/TX2 NX module
Both Ethernet ports are accessed via two RJ-45 jacks. The magnetics needed for these ports are available on the
FloydSC carrier. The jacks indicate Link and speed status associated with each port using integrated LEDs.
When a daughterboard is used for expansion, the second Ethernet interface is unavailable since the PCIe Port 1
is utilized by the Daughterboard.
Serial Ports
The JetBox-FloydSC provides two serial ports, one with jumper selectable RS232 or RS485 protocol modes and
one dedicated RS232. Since the serial ports from module are 1.8V complaint, they are level shifted to 3.3V logic
before feeding to the transceivers.
Digital I/O
The JetBox-FloydSC provides 8x digital I/Os , which are individually configurable as an output or input. The digital
I/Os are realized using an I2C GPIO expander. The I2C control for the expander is directly fed from the module.
This I2C GPIO expander can support both 3.3V and 5V, so a voltage translator is used to between module and
I2C GPIO expander. This expander device is accessible on the I2C address 0x22. The IO voltage is selectable
using jumper setting refer section 9.1 for Jumper configuration details.
The Digital I/Os are made available on a 11-position 3.5mm screw terminal connector.
