General safety instructions
Please read the following safety precautions carefully before putting this device to use to avoid
any personal injuries, damage to the instrument, or to the target system. Use this instrument
only for its intended purpose as specified by this manual to prevent potential hazards.
Use included power cord and power supply
The enclosed power supply has been approved for use by iSYSTEM. Please contact iSYSTEM if
you need to consider an alternative power.
Use grounding wire
Prior to applying power to either the BlueBox or the target, connect the device and the target
system together with the included grounding wire. This is to avoid potential damage caused by
any voltage difference between the device and the target system.
Use proper overvoltage protection
Ensure proper protection to avoid exposing the BlueBox device or the operator to overvoltage
surges (e.g. caused by thunderstorm, mains power).
Do not operate without cover
Do not operate the device with cover removed.
Avoid circuit and wire exposure
Do not touch exposed components or wires when the device is powered.
Do not operate with suspected damage
If you suspect damage may have occurred, the BlueBox device must be inspected by qualified
service personnel before further operation.
Do not operate the device outside its rated supply voltage or environmental range
Consult with iSYSTEM before using equipment outside of the parameters provided in this
manual.

Introduction
Galvanic isolation is used where two electric circuits must communicate, but their grounds may be
at different potentials. It is an effective method of breaking ground loops between the two circuits.
Galvanic isolation is also used for safety, preventing accidental current from reaching ground
through a person's body.
iSYSTEM Galvanic Isolation Adapters provide a basic isolation that withstands high voltages.
To prevent injury to personnel when dealing with potentially hazardous voltages it is mandatory to
have a second protection measure in place, in case the first insulation barrier fails. This is termed
double or, reinforced isolation. How should a double isolation be implemented depends on the use-
case or application setup.
It is your responsibility to check the local safety directives applicable to your company and
country to ensure that all requirements are met.
MPC5xxx / SPC5 14-pin 2.54 mm Galvanic Isolation Adapter is used to electrically isolate:
· iSYSTEM iC5700 BlueBox in conjunction with
o14-pin 2.54 mm MPC5xxx Debug Adapter (Ordering code IC50150) or
oMPC5x/SPC5x Aurora Active Probe MPC5x/SPC5x Aurora Active Probe (Ordering code
IC57150) + 14-pin 2.54 mm JTAG Converter (Ordering code IASAM34MPCPIN14)
from the embedded target.

properly.

Device overview
A – DEBUG TOOL connector.
B – TARGET connector.
C– LED lights indicate power supply status.
If LEDs on the GI Adapter are OFF, immediately turn everything OFF!
D – USB-C Power supply socket (PWR).
Use only original iSYSTEM USB-C Power supply for powering and connecting with the GI
Adapter, otherwise the primary functionality of the GI Adapter would be counteracted.

Connecting procedure
Do not use a Grounding wire between the BlueBox and the embedded target since it would
counteract the primary functionality of the Galvanic Isolation (GI) Adapter!
1. Make sure your hardware is powered OFF.
· Embedded Target
· BlueBox
· GI Adapter
2. Connect a Debug Adapter to the BlueBox. Refer to the BlueBox User Manual for more details on
connecting the Debug Adapter.
3. Connect the Debug Adapter to the GI Adapter.
4. Connect 1:1 Ribbon cable which is delivered along this package to the GI Adapter.
5. Connect 1:1 Ribbon cable to the embedded target.
6. Connect BlueBox, GI Adapter and Target to the power supply.
Use only original iSYSTEM USB-C Power supply for powering and connecting with the GI
Adapter, otherwise the primary functionality of the GI Adapter would be counteracted.
7. Power ON the hardware in the following order:
· BlueBox
· GI Adapter
· Target
If LEDs on the GI Adapter are OFF, immediately turn everything OFF!
