3. A Tour of Gigastar 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.

3.1. Label and Status Indicators

The RAD-Gigastar2 has two membrane buttons, and . Pressing one button will activate the LED inside it and deactivate the other button’s LED.

3.1.1. The Button

Device Status

When this button is active, the color of it’s LED indicates the following.

LED Behavior	Status
Slow Flash	Device Powered
Rapid Flash	Online with Vehicle Spy (Ethernet)
Rapid Flash	Online with Vehicle Spy (TCP)
Rapid Flash	Online with Vehicle Spy (USB)

Network/gPTP/Logging Status

Notice that the white outline of this button intersects with a white line that connects the white text above the other status LEDs. This is to denote that when this button is active, the other LEDs show information related to the white labels above them.

Label	Network or Function	LED Behavior
T1 1	AE01 (1000BASE-T1)	Flash = Message TX Flash = Message RX Flash = Network Error
T1 2	AE02 (1000BASE-T1)
SFP 1	Ethernet
SFP 2	Ethernet 02
CAN	CAN1-4 (Logical OR of all CAN Busses)
LIN	LIN1-6 (Logical OR of all LIN Busses)
gPTP	gPTP status	Solid	gPTP Leader
		Fast Flash	gPTP Follower (locked)
		Slow Flash	gPTP Follower (not locked)
		Solid	Error
			gPTP disabled
	Logging Activity	Flash	NVM Write
		Flash	NVM Read
		Flash	NVM Error
		Flash	Trigger Collection Active

3.1.2. The Button

Notice the blue outline of this button intersects with a blue line that connects the blue text below the LEDs. This is to denote that when this button is active, the LEDs display information related to the blue labels below them. (The 10BASE-T1S Networks 1-8)

The color of the LED within this button indicates which information is displayed for the 10BASE-T1S networks.

	LED Behavior	Port Status
Activity		Frame Transmitted
		Frame Received
		Error (e.g. Bad CRC, PLCA error)
		Port Disabled
PLCA		BEACON present
		Collision
		Jabber
		Unexpected BEACON
		Empty Cycle
		CSMA/CD Mode
		Port Disabled
gPTP		Disabled
	Solid	Leader
	Blinking	Follower/Locked
	Blinking	Follower/Not Locked
		Error

Signal Quality Index (SQI)

Momentarily holding will display SQI information for 100/1000BASE-T1 networks, and holding will display the SQI of the 10BASE-T1S networks.

The color of the LED can be interpreted as follows.

LED Color	SQI		Bit Error Ratio
	T1S	T1
	0	0	BER > 10e-10
		1
		2
	1	3	BER < 10e-10
		4
	2	5
		6
		7

3.2. Connector Interfaces

3.2.1. Device Power, SFPs, and CAN/LIN interfaces

DB-26 Connector: CAN/LIN

In addition containing an alternate power connection, the CAN, LIN, and DoIP interfaces are located in this connector. The pin assignments are listed below and can also be seen on the bottom label of the device.

Mutually Exclusive Networks

The RAD-Gigastar2 features two different firmware configurations based on which networks are needed for an application. The use of some networks are mutually exclusive between these two configurations. The chart below shows the pin assignments for each port and their availability in a given firmware configuration.

Pin	Signal
	MAX LIN Config		MAX CAN/T1S Config
1	LIN 01		LIN 01
2			DW CAN 04 L
3	LIN 03		LIN 03
4	DW CAN 01 L		DW CAN 01 L
5	LIN 05		LIN 05
6			DW CAN 02 L
7			DW CAN 03 L
8	LIN 07
9	LIN 09
10	GND		GND
11	LIN 02		LIN 02

26	LIN 16

SFP Ports

The RAD-Gigastars ships with two 1000BASE-T SFP modules which can be used in the sockets SFP1 and SFP2. 100/1000BASE-T1 and Optical SFP modules are also available for purchase.

SFP Compatibility

While there are many types and many suppliers of SFP modules, it is important to use hardware that has been fully verified by ICS to insure full compatibility and reliable performance.

ICS Approved SFP Modules

Media	Manufacturer	Part Number
100/1000BASE-T1	Intrepid	88Q2112 SFP 88Q2221M SFP
10/100/1000BASE-T (Copper)	Finisar	FCLF8522P2BTL
	FS	SFP-GB-GE-T
1000BASE-SX (Optical)	Finisar	FTLF8519P3BTL
	FS	SFP1G-SX-85

Configuring Intrepid’s 10BASE-T1S and MultiGBASE-T1 SFPs

Intrepid’s 10BASE-T1S and MultiGBASE-T1 SFPs are not compatible with the RAD-Gigastar2 however, they can be configured using the RAD-Gigastar2 for use in another host.

Barrel Jack: 5-48V (Right):

The device can be powered with this barrel jack using the DC supply provided with your purchase. If an alternate DC supply is used, it must be within the range of 5V-48V with a current capacity of 2 Amps, or the device may malfunction or be permanently damaged.

3.2.2. 100/1000BASE-T1, 10BASE-T1S, and USB Interfaces

H-MTD Connectors: 100/1000BASE-T1 (AE01 / AE02)

The H-MTD connectors on the left are connected to the 100/1000BASE-T1 ports, AE 01 and AE 02.

H-MTD Connector Pinout
Pin #	Label	Description
1	TRD+	Data transmit and receive, positive
2	TRD-	Data transmit and receive, negative

Isolated USB 3.0 (Type C Connector)

This USB port is electrically isolated to protect it and a host computer from potential damage. It functions identically to connecting the RAD-Gigastar2 to a computer using one of the SFP ports. It has the advantage of supporting transfer speeds higher than 1Gbps, as well as allows the use of the SFP ports in a second active tap configuration.

NanoMQS Connectors: 10BASE-T1S (AE03 - AE10)

Each 10BASE-T1S port has two sets of pins on the NanoMQS connectors to minimize stub length by connecting the RAD-Gigastar2 to a mixing segment in an “In/Out” configuration.

A NanoMQS plug and pin kit is shipped with the RAD-Gigastar2, however additional kits can be purchased here

The same components are also available from many electronic component distributors

• NanoMQS Crimp Contacts 2-2112449-1

• NanoMQS Plugs 2177558-1

The following fully assembled cables are also available for purchase.
