4. LED Display Control
4.1 Power
The Sapphire-BTX can be powered by two sources:
Via a battery – AB or V mount depending on the device battery plate
Via 9-36VDC input to the 6-way Hirose (male) power connector
The power switch should be used to control power to the device (see Section 3.4). When the power is
switched on, the power LED will be illuminated (see Section 3.5) and the unit will boot up.
4.2 Introduction
Some product features are licensed and may not be available for selection. See Section 2.5 for license
options.
The Sapphire-BTX has an LED display and control buttons which can be used to monitor and
configure the BTX without the need to connect to a PC device.

5. Web Browser Control
5.1 Power
The Sapphire-BTX can be powered by two sources:
Via a battery – AB or V mount depending on the device battery plate
Via 9-36VDC input to the 6-way Hirose (male) power connector
The power switch should be used to control power to the device (see Section 3.4). When the power is
switched on, the power LED will be illuminated (see Section 3.5) and the unit will boot up.
5.2 Introduction
Some product features are licensed and may not be available for selection. See Section 2.5 for license
options.
The Sapphire-BTX has a comprehensive web user interface (WUI) for detailed monitoring and control.
The WUI is accessed via a web browser using the IP address of the BTX, so an Ethernet connection
to a PC device is required.
Our devices are shipped to you with the IP DHCP setting enabled. This means that if the Sapphire-
BTX is connected to a network which is administered by a DHCP server, the IP address will be
automatically assigned. If the device is connected to a network which does not have a DHCP server,
contact your Network Administrator for an IP address you can use.
Re-configuration of the IP settings can be achieved via the web interface (see Section 5.7), or via the
LED display control (see Section 5.3.2).
Note: If you are using a standalone PC or laptop, you will need to set the IP address of the PC to
match the IP address range of the device. Refer to Section 7.1 to find out how to do this.

5.3 IP Address Identification
5.3.1 Device Finder
DBS’ Device Finder application can be used to identify DBS product IP addresses on a network.
Device Finder comes as a simple executable file which can be downloaded from DTC’s WatchDox
facility, see Section 8.1. This can be saved to the PC desktop.
Double-click the Device Finder executable to open the application. All DBS devices attached to the
network will be detected. Click Open to initialise communications with your PC’s default web browser.

5.3.2 LED Display
The IP address of the BTX can be found and edited, if required from the LED display. This can be
useful if the device is not connected via a DHCP server, or the IP address does not match the subnet
of the PC and the IP address settings need to be changed.
Note: See Chapter 4for details of LED display control.
The IP address can be discovered in the Unit page by scrolling down to the IP settings.
Change the DHCP Mode setting to Off if you want to enter the IP settings manually.
5.4 Open the Web Interface
Once the IP address has been confirmed, open a web browser on a PC device and enter the IP
address of the BTX in the address bar. Alternatively, if running Device Finder, click Open on the line of
the device address.
The web interface will open to the Status page.
