3. A Tour of RAD-Galaxy 2 Hardware

Before learning how to configure and set up the device, let’s examine the device from all sides to understand all of its interfaces and status indicators.

Warning

The RAD-Galaxy 2 is a complex device that does not contain any user-serviceable parts. Do not attempt to open the case of the RAD-Galaxy 2 unless specifically instructed to do so by an Intrepid Control Systems technician, or you risk possible injury or damage to the unit.

3.1. Front Panel Buttons and LED Indicators

RAD-Galaxy 2 Front View

3.1.1. Device Status LEDs

Bootloader

If the LED flashes red (with no alternating color), this indicates the RAD-Galaxy 2 is updating its firmware or in bootloader mode waiting to update firmware by connecting to Vehicle Spy or neoVI Explorer.

Firmware Flashing	Red Flash	Red Flash
Device in bootloader	Green Flash	Red Flash
Device Unpowered	off	off

Safe removal of power in bootloader mode

If the device is in bootloader mode, power should not be removed until both LEDs on ETH03 are inactive. Active LEDs on ETH03 indicate that there is a device initialization that must not be interrupted by removing power. Removing power during this initialization will cause the RAD-Galaxy 2 to malfunction until it is placed back in bootloader mode using the front panel buttons and the initialization is allowed to complete successfully.

If the LED in inactive, or flashes colors other than red, then the following tables define the LED indications.

Operating Mode

		VSPY Connection	Coremini
Green	Slow Flash (1Hz)	Offline	Not Running
	Fast Flash (2.5Hz)	Connected
Orange	Fast Flash (2.5Hz)	Offline	Running
Green/Orange (alternating)	Fast Flash (2.5Hz)	Connected
Off	Device Unpowered
Red Flash	In Bootloader

CAN/LIN Status

	Activity	Error Indication
Green Flash	CAN TX	Red Flash following a Green or Orange Flash
Orange Flash	CAN RX
Green/Orange (Alternating)	CAN TX and RX
Red Flash Only	In Bootloader

3.1.2. CN1/CN2/CN3 Status LEDs

The green LEDs directly below the three H-MTD Connectors (CN1/CN2/CN3) indicates the link status and activity of the 100/1000BASE-T1 ports 1-16. The following table describes their behavior.

Off	Link Down
Solid Green	Link Up
Flashing Green	Link Up with RX/TX Activity

3.1.3. ETH01/02/03 LEDs

Each 10GBASE-T port has two status LEDs

STA (Status)

Off	Link Down
Flashing Green	RX/TX Activity

SPD (Speed)

If the link is active, the link speed is indicated as follows.

Off	Link Down
1 Flash	Linked at 10Mbps
2 Flashes	Linked at 100Mbps
3 Flashes	Linked at 1Gbps
TBD	Linked at 2.5Gbps
TBD	Linked at 5Gbps
4 Flashes	Linked at 10Gbps

3.2. Front Panel Buttons

Buttons SW1 and SW2 have no runtime function at this time and should only be used if so instructed by customer support in the processing of resolving a problem.

If both buttons are held for a period of 5-10 seconds, the RAD-Galaxy 2 will remain running in the bootloader awaiting a firmware update from Vehicle Spy or neoVI Explorer. Bootloader mode can be identified by a specific LED behavior.

If the device is accidentally put into bootloader mode, normal functionality can be restored by cycling power. However, power should not be removed until both LEDs on ETH03 are inactive for reasons explained in the *bootloader section of this guide.*

3.3. Connector Interfaces

3.3.1. Barrel Jack

The RAD-Galaxy 2 is powered using the barrel jack on the left of the front panel. Power requirements can be found Device Power

3.3.2. USB Type B

This connection is reserved for internal and future use.

3.3.3. Ethernet Ports

ETH01 (RJ-45)

ETH01 is the primary interface to a host PC when using Vehicle Spy or Intrepid’s Open Source API

ETH01/ETH02 (IX Connectors)

ETH01 and ETH02 use the industrial IX connector and have multiple uses depending on the RAD-Galaxy 2 configuration.

• Alternate computer connection

• Streaming CMP traffic to a PC or data logger

• A MultiG active tap pair

In many cases, an IX to RJ45 cable is required to connect these ports to office or lab computers. They are widely available through distributors or can be at the links given in this section

AE01-AE16 (H-MTD)

The three H-MTD connectors contain ports AE01-AE16, which are the 100/1000BASE-T1 ports that can be used in an active tap configuration or independently. Details on this configuration can be found in this section

The mating connector for CN1-3 is Rosenberger part number E6K10F-1CAZ5-Y. Information on premade harnesses can also be found this section

The cavity assignment of each connector are as follows (as seen looking into the connectors of the RAD-Galaxy2)

CN1

CN2

CN3

Loop Back Ports

Note the 2 cavities on CN3 labeled “LB” are a loop back connection. These ports are connected internally and are intended as a convenient way to bypass an active tap for debugging purposes.

3.3.4. HD-26 Conventional Network Interface Connector (CAN/MISC)

This male, high-density, 26-pin D-subminiature connector contains the CAN and LIN networks, as well as the miscellaneous I/O

Device Power

Unlike many Intrepid products, the RAD-Galaxy 2 cannot be powered using the DB-26.

AIN 1/AIN 2 - Differential Analog Input

The RAD-Galaxy 2 measures the differential voltage between AIN1 (upper voltage) and AIN2 (lower voltage). If a differential measurement is not needed, AIN2 must be grounded for proper operation. This input is mutually exclusive with the PWMIO.
