This document is a guide for adding a QUARTZ-GOLD router to your system.
The QUARTZ-GOLD is a range of industrial LTE routers that can be used as the
gateway router to a WAN or the 4G LTE cellular network, with the option of automatic
fallback between the two.
This document is aimed at engineers and describes the electrical characteristics and
hardware operation of the QUARTZ-GOLD router.

Hardware Manual

General Description
The QUARTZ-GOLD is powered with a Broadcom 900 MHz ARM Cortex A7
processor with 128Mb ash and 1Gb of DDR3 RAM. This processor runs a
proprietary Operating System based on Linux.
As well as offering two Gigabit Ethernet interfaces, the QUARTZ-GOLD also offers an
RS232 interface that may be used to create a network serial port with products such
as door access control panels and alarm panels.
IEEE 802.11 b/n/ac WiFi comes as standard, and the QUARTZ-GOLD also optionally
supports GNSS for asset tracking applications.
Three modes of networking operation are possible:
1. LTE cellular router where the WAN connection of the router is the LTE cellular
interface. In this mode both Ethernet interfaces are for LAN use. Internet
connectivity comes from the internal cellular interface.
2. WAN router where one of the Ethernet ports of the router is used as the WAN
connection. The WAN port in this case would normally be connected to a cable
or ADSL modem to obtain Internet connectivity.
3. Backup router which combines the two above modes. The router can switch
between the cellular and WAN connections automatically to maintain Internet
connectivity in the event that one path fails. The preferred route can be set to
cellular or WAN.

*QUARTZ-GOLD with the GNSS option only supports one cellular antenna, so the maximum
data download rate for LTE and DC-HSPA+ is halved on these models as they are unable to
support diversity.
NOTE: All upload and download speeds are those supported by the QUARTZ-GOLD. Actual
speeds achieved will be dependent on the capabilities of the network cell connected to, any
network congestion, and the radio link quality.
NOTE: The cellular connection type obtained by the router is shown on the Status>Overview
page of the routers web interface.

NOTE: This section is only applicable to models with the GNSS option.
The GNSS receiver uses multi-constellation technology which allows it to use all the
following constellations to determine the position: GPS, GLONASS, BeiDou, Galileo
and QZSS. By using all these constellations, the GNSS in the QUARTZ-GOLD gives
excellent positioning availability and accuracy.

Interfaces
LAN / WAN Port
Figure 10. QUARTZ-GOLD LAN / WAN Connection
For initial setup, it is recommended to connect the LAN port to the PC that will be
used to congure the router. There are two RJ45 interfaces. Please take care not
to use the interface marked WAN/LAN until the router has been congured. WiFi
may be enabled as part of the conguration process, and when enabled further
conguration may be done over a WiFi connection to the router.
Once the router is congured, the WAN (if used) may be connected. The WAN
port, if used, is the port to which a wired Internet connection is available. This is
usually a cable/xDSL/Fibre modem.
LAN / Optional WAN Port
LAN Port
LAN Characteristics
2x 10/100/1000 Mbps Ethernet RJ45 Ports supporting IEEE 802.3az specication
for Energy Efcient Ethernet (EEE). Individual ports automatically detect short cable
lengths and scale power accordingly.
One port is for LAN only. The second port may be software congured as a LAN
or a WAN port.
Support for full and half duplex in 10 Mbps and 100 Mbps modes, and full duplex
for 1000 Mbps. IEEE 802.3x frame-based ow control is supported in full duplex
mode.
