4. A Tour of RAD-wBMS Hardware

Let’s now take a short tour of the RAD-wBMS hardware. We’ll examine the device from all sides, showing its external components and explaining what each does. This will help you become more familiar with the unit so setup comes easier. Then, you will be ready to configure and use your device.

4.1. Case Design

The RAD-wBMS is enclosed in a sturdy black-anodized metal case. The device has been designed and tested for in-vehicle use, and is operational in a temperature range from -40°C to +85°C (-40°F to 185°F).

Connectors and ports are often a point of failure with hardware devices. To ensure that the RAD-wBMS provides you with years of reliable service, Intrepid has ruggedized the physical interfaces on the device by using reinforced metal connectors.

To further protect the device against bumps and drops, the RAD-wBMS has green-colored rubber bumpers on both ends. These bumpers are removable, but there is no need to do this under normal circumstances, and we recommend that you leave them in place.

The bottom of the RAD-wBMS contains useful reference information, including the device serial number, pinouts of its wBMS SPI port and Intrepid’s contact information.

4.2. Left Side Interfaces and Connectors

The left side of the RAD-wBMS contains 3 components:

  • RF-1 socket (left)

  • isoSPI™ interface (middle)

  • RF-2 socket (right)

4.2.1. isoSPI™ Interface

This port holds a Molex connector receptacle (Molex Part No. 5016461600) to interface with isoSPI™. The connector receptacle measures 18mm x 11.05mm x 8.2mm, and the pinout can be found below. In addition, Crimp terminals are 2.00mm Pitch, iGrid Female Crimp Terminal, Tin (Sn) Plating, 22-26 AWG, Reel (Molex Part No. 5016471000)

SPI is a synchronous, full duplex, main-subNode-based interface which is used to connect to a wired Battery Node network. IsoSP™ consists of two isolated bidirectional SPI communication channels through a single-twisted pair connection which creates network redundancy.

4.3. Right Side Interfaces and Connectors

The right side of the RAD-wBMS contains 3 components:

_images/image8.png

  • RJ45 (Ethernet) Port (left)

  • USB 2.0 Interface (middle)

  • Micro DB-9 Connector (right)

4.3.1. RJ45 (Ethernet) Port

The RAD-wBMS has one Megabyte Ethernet (10/100Base-TX) port. Ethernet is used to interface with your computer, DoIP, XCPoE and more. The Ethernet port also has an LED at the top left and top right corner.

Orange Activity LED (Top Left)

This LED flashes when traffic is passing in either direction over the attached Ethernet cable. If no traffic is passing through the cable, the LED will not light up.

Green Link LED (Top Right)

This LED indicates that a valid link has been established between your device and another 10/100 Ethernet device. If this LED does not light up, there is either an invalid connection with the wire or the Ethernet port may be dysfunctional, contact Intrepid support if needed.

4.3.2. USB 2.0 Interface

This USB port serves as the connection to a host computer for configuration, data transfer, and power. The RAD-wBMS has an isolated USB 2.0 (240Mb/s) interface. This port is used to connect the RAD-wBMS to a computer for configuration and monitoring.

4.3.3. Micro DB-9 Connector

This port allows the RAD-wBMS to transmit and receive messages on two CAN/CAN-FD channels. The pinout is listed below and can also be found on the back of the RAD-wBMS.

4.4. Membrane LED Display and Keypad

_images/image29.png

The membrane contains 10 LEDs that provide immediate visual feedback about the status of the device, and two keypad buttons that can be used to toggle the indicator mode and for other functions.

Keypad Buttons and LEDs

There are two keypad buttons on the RAD-wBMS’s top membrane: one that says wBMS in green near the top left, and one that says CAN ETH in white near the bottom right. Pressing either button changes the meaning of the 8 LEDs. Whichever button’s LED is flashing signifies the meaning of the other 8 LEDs.

4.4.1. wBMS (Green Button)

When pressed, “activates” the green set of LED labels: each LED corresponds to the green label above the LED. The meanings of the labels are described below from left to right, top to bottom.

The LED above wBMS the button flashes white when the white labels are selected and the RAD-wBMS is offline. The LED alternates between green and blue when the blue labels are selected and the RAD-wBMS is online signifying that the RAD-wBMS is ready to receive and transmit messages.

Label

Description

wBMS

  • Flashing Orange when the Green set of labels is “activated” (See above) but the RAD-wBMS is not connected to a computer

  • Flashing White when the Green set of labels is “activated” (See above) and the RAD-wBMS is connected to a computer but offline in Vehicle Spy 3

  • Alternating Blue and Green when the Green set of labels is “activated” (See above) and the RAD-wBMS is online in Vehicle Spy 3

4.4.2. CAN ETH (White Button)

When pressed, “activates” the white set of LED labels: each LED corresponds to the white label below the LED. The meanings of the labels are described below from left to right, top to bottom.

The LED above the button flashes white when the white labels are selected and the RAD-wBMS is offline. The LED alternates between green and blue when the white labels are selected and the RAD-wBMS is online signifying that the RAD-wBMS is ready to receive and transmit messages.

LED Color Meanings

For networks, different colors indicate different statuses:

  • Green: Device is transmitting messages on this channel.

  • Blue: Device is receiving messages on this channel.

  • Red: Device is detecting errors on this channel.

It is possible for more than one LED component to be lit, producing the following results:

  • Green+Blue (Cyan): Device is transmitting and receiving on this channel.

  • Green+Red (Yellow): Device is transmitting and detecting errors on this channel.

  • Blue+Red (Magenta): Device is receiving and detecting errors on this channel.

  • Green+Blue+Red (White): Device is transmitting, receiving and detecting errors on this channel.

4.4.3. Miscellaneous LED Indicators

  • Depending on which set of labels is “selected”, that button’s LED will flash yellow when the RAD-wBMS is connected to power but not a computer

  • The aforementioned button will flash white once the RAD-wBMS is offline and has successfully connected to power and a computer

  • All 10 buttons will be solid red when the RAD-wBMS is in bootloader mode

  • When entering bootloader mode, the RAD-wBMS’s 5 LEDs on the top and bottom row will alternate flashing Green, once the device has begun reflashing, the LEDs will be solid Red. After the RAD-wBMS has finished flashing firmware, the device will reconnect to the computer. For more information on updates see 5.3.3
