QUARTZ-ONYX
Hardware Manual
The QUARTZ-ONYX uses a Mediatek 880 MHz MIPS dual-core processor with
256 Mb flash 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.
