5 BreadCrumb LX/LX3 Firmware Upgrade

Each BreadCrumb relies on low-level software known as firmware for proper execution. For a

BreadCrumb to communicate with other BreadCrumb devices or a BC|Commander client, the

firmware version of the device must be compatible with the firmware versions of all other devices

within the network, and with the version of BC|Commander running on the client computer.

Note

For procedures to install and upgrade the BC|Commander management application,

refer to the latest BC|Commander User Guide.

The firmware is routinely updated by Rajant Corporation to add new product features, support new

applications, and to fix reported problems. To upgrade the firmware on a BreadCrumb, you must

obtain the appropriate firmware file for your BreadCrumb model from Rajant. Save the file on a

computer on which the BC|Commander management application has been installed.

5.1 Over The Air Firmware Upgrade

One method of upgrading the firmware is a process called “Over-the-Air (OTA) firmware upgrade”.

This is a remote process, controlled and initiated by a system administrator using BC|Commander.

Follow the instructions in the BC|Commander User Guide (Administrative Tasks – Over-the-Air

(OTA) firmware upgrade) to perform the firmware upgrade process.

5.2 USB Firmware Upgrade

Another method is the USB firmware upgrade. This process takes place at the BreadCrumb's

location and requires a properly prepared USB storage device. To perform the firmware upgrade

process, follow these procedures:

1. Prepare a USB storage device with the appropriate firmware file using BC|Commander.

Follow the instructions in the BC|Commander User Guide (Administrative Tasks – USB

Firmware Upgrade).

2. Turn power to the BreadCrumb OFF.

3. Connect the USB storage device to the BreadCrumb's USB port.

4. Turn power to the BreadCrumb ON.

5. The firmware upgrade process will take several minutes. Observe the BreadCrumb's Status

LED to monitor progress.

(a) When the USB firmware upgrade begins, the Status LED will start blinking yellow,

which indicates progress. When the process nears completion, the blink rate will increase

from once per second to several times per second.

(b) If the firmware upgrade completes successfully, the Status LED will rapidly rotate

between red, green, blue, cyan, magenta, yellow and white colors.
