Hardware Manual
Download Latest Edition
This document covers all the electrical and mechanical aspects of the QUARTZ-
ONYX 5G NR router. For programming and use of this product in a computer
network, please refer to the QUARTZ-ONYX Software Manual.
This manual is intended to guide on how to connect the QUARTZ-ONYX 5G NR
router into a computer network so that it may be used as the gateway router either to
a WAN or the 5G NR cellular network, with the option of automatic fallback between
the two. For complete network conguration, it is necessary to set up the network
using the built-in web server for which reference to the companion software manual is
required.

QUARTZ-ONYX
Hardware Manual
Download Latest Edition
The QUARTZ-ONYX uses a Mediatek 880 MHz MIPS dual-core processor with
256 Mb ash and 2 Gb of DDR3 RAM. This processor runs a proprietary Operating
System based on Linux which controls the web interface and routing functionality
of the router. VPN throughput is enhanced with a hardware IPSec crypto engine
onboard the MIPS processor. The processing system is augmented with an STM32
ARM Cortex coprocessor which controls the operation of the GPIO and serial
interfaces.
The cellular capabilities of the QUARTZ-ONYX are powered by the Quectel RM500
QAE Module which uses the Qualcomm Snapdragon X55 5G Modem and is
manufactured on a leading edge 7 nm semiconductor fabrication process. Dual SIM
operation provides cellular network resilience when there may be connectivity issues.
As well as offering four Gigabit Ethernet interfaces, the QUARTZ-ONYX also offers
RS232 and RS485 interfaces that may be used to connect serial ports on products
such as door access controllers and alarm panels to the Internet.
Further peripheral connectivity is provided by an intelligent GPIO interface that can
send SMS messages on change of input state, and control outputs based on input
state or SMS messages received.
WiFi 5 comes as standard, and the QUARTZ-ONYX also optionally supports GPS
using a 56-channel u-blox 7 engine for asset tracking applications.
Three modes of networking operation are possible:
1. 5G NR cellular router where the WAN connection of the router is the 5G NR
cellular interface. In this mode all 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 should one path fail. The preferred route can be set to cellular or
WAN.

Table 4. Power Consumption Characteristics
Power consumption
*When streaming BBC iPlayer at highest video quality
IMPORTANT: Power consumption currents are measurements of average current.
When the cellular connection is active there will be short current pulses signicantly
greater than the average values provided. It is important that the 12V supply used to
power the router can deliver at least 2.0 A to prevent network disconnections caused
by these current pulses.
All current measurements with the cellular modem enabled are started after the
router has obtained an IP address from the cellular network and is in a steady state.
An 800 MHz LTE cell with a measured signal strength of 15 was used when taking
measurements. Measurements for all communication interfaces are with them
enabled and connected but no trafc owing. WiFi is used with both 2.4G and 5G
enabled. LAN power measurements are made with a single LAN port used. GPS is
measured after a position x has been obtained.
IMPORTANT: BBC iPlayer may be accessed at https://www.bbc.co.uk/iplayer. Much
content could be blocked outside of the UK, but BBC news is always likely to be
available internationally.
The power consumption when used with UMTS, LTE and 5G NR networks is broadly
similar. Cellular power consumption will be affected will be affected more strongly
by proximity to the serving cell (closer to the cell = less transmitting power required),
weather (heavy rain/snow = more signal attenuation and greater transmit power) and
operating band (lower frequencies are generally lower power).

supporting the 4 ports is capable of 2 Gbps wire speed.
DI1 and DI2 are voltage level triggered inputs. DI1 is internally pulled down to 0 V using
a 94K Ω resistor. DI2 is internally pulled up to 5 V using a 4700 Ω resistor, but not
designed to source any current if not used as an input. It is acceptable to leave these
inputs disconnected if not used.

Radio Characteristics
The Quartz-ONYX supports WiFi using a MediaTek radio that is IEEE802.11n/ac
compliant. This means that it will work with other WiFi adapters supporting IEEE
802.11a/b/g/n/ac. The 2.4 GHz and 5 GHz wireless bands may be independently
congured.
2.4 GHz bands may be set to 20 or 40 MHz channel width.
5 GHz bands may be set to 20, 40 or 80 MHz channel width.
A channel congured for 2.4 GHz operation may be used as 802.11b only, 802.11g
only, 802.11b/g mixed and 802.11n only, as well as the default 802.11b/g/n mixed
mode (congured by software).
A channel congured for 5 GHz operation can be used as 802.11a only and 802.11n
only, as well as the default 802.11ac mixed mode (congured by software).
WiFi Characteristics
Table 14. 2.4 GHz WiFi band support
IMPORTANT: While the QUARTZ-ONYX can support all 2.4 GHz WiFi channels, the regional settings in the WiFi conguration
page will limit the available channels to meet the regulatory requirements of the country in which it is being used. Siretta always
recommends that the region setting be correctly congured for the country in which the router is being used.

the regional settings in the WiFi conguration page will limit the available channels to
meet the regulatory requirements of the country in which it is being used. The regional
setting also correctly applies transmit power and DFS requirements for the country of
use. Siretta always recommends that the region setting be correctly congured for the
country in which the router is being used.
