Upgrading software with the Welch Allyn Service Tool
The Spot 4400 and the Welch Allyn Service Tool (WAST) interact through Ethernet over USB
technology, enabling the device to function as a USB device with both a network and an IP address.
This connection separates logically into two distinct interfaces: a generic USB serial connection and
a Remote Network Driver Interface Specification (RNDIS) network interface, which is a Microsoft
Windows driver. Most interactions between the WAST and the Spot 4400 take place over the
generic USB serial connection. In contrast, software upgrades require the RNDIS interface for the
device to connect the WAST and download the firmware.
During software upgrade, the Ethernet over USB interface with the WAST is auto-configured with
the specifications noted in the table below. When the Spot 4400 reaches out to the WAST for the
firmware package, it uses either one of the following TCP ports: 80/443. Be prepared to modify any
firewall(s) that prevent incoming connections to allow this traffic. The WAST attempts to configure
the Windows firewall by opening this specific port on the RNDIS interface. If administrative controls
such as a Group Policy Object (GPO) or third-party software have been implemented to prevent
this change, the WAST attempts to diagnose the problem and then inform you of possible
remediation steps. Work with your IT staff or Network Administrator as needed to enable this
functionality.

At the start of a software upgrade, the Welch Allyn Service Tool creates a local HTTP server and uses
the USB connection to transfer necessary file package to the Spot 4400. Once the file package is on
the device, it launches the installation of host controller firmware and reboots the device
immediately following the installation. When the device auto-reboots, the software upgrade of
individual modules and sensors (NIBP, SpO2, and/or Temperature) is complete.
Software rollback capability
The Spot 4400 utilizes a primary and secondary software structure. In the final step of the software
upgrade, the device rolls the previous firmware package to a secondary image and identifies the
newly installed firmware as its primary image. This structure allows rollback to previous versions as
needed. For example, if you performed a software upgrade and then determined that it didn't
meet your expectations or conform to your workflow, you can execute a software rollback in
seconds and limit device downtime. To roll back your software, follow these steps:
1. Connect the device to your laptop and open the Welch Allyn Service Tool.
2. Click the
Configure tab.
3. In the Current settings window, click Change... .
4. Click the Device Software Rollback tab.
5. Click Rollback .
6. In the Confirm Device Software Rollback dialog, click Yes to confirm.
