cnReach N500 Radio Modules
An overview of the cnReach N500 Radio Modules is provided in this section. More details are available
in the technical reference section of Chapter 3 .
The N500 is available in 900 MHz with the same radio supporting both MAS licensed and ISM
unlicensed spectrum. cnReach is also available in additional licensed bands 700 MHz, 406-430 and
450-470 MHz and 217-222 MHz. In 900 MHz unlicensed operation, the radio operates in a frequency
hopping spread spectrum mode which hops on various frequencing never dwelling on the same channel
for very long. In licensed mode operation, the radio operates solely on the channel or channel-pair
allocated. In all cases, cnReach operates as a TDD radio.
The N500 series has a flexible set of I/O options including two serial ports, two Ethernet ports and
optional integrated I/O.
In 900 MHz unlicensed band, the radio can be deployed in point-to-point (PTP), point-to-multipoint
PMP) store-and-forward and back-to-back repeater modes.
In licensed bands, the radio can be deployed in point-to-point (PTP), point-to-multipoint PMP) and
back-to-back repeater modes.
Key Features include:
• Layer 2 Bridging and Layer 3 Routing
• Adaptive Modulation
•
Single and Dual Radio options for advanced relay and store-and-forward applications
• AP Synchronization
• Secure communications with AES 128/256-bit encryption with password authentication
• Extensive I/O capabilities easing the transition from serial to all-IP networks with multiple serial
ports, Ethernet ports and analog/digital I/O built-in
cnReach radios all have the same design with front access to communication ports and side access to
RF and I/O connections. The radio may or may not be DIN rail mounted with an optional DIN-rail mount
connector. The top of the radio enclosure is a heat sink needed for high-power dual-radio applications –
the finned heat sink surface should be kept clear of any materials. The practice of stacking radios on top
of each other is not recommended as a gap should always be maintained between radios to aid with
heat dissipation.
The front of the radio includes (from left to right) a 10-32VDC power connector, two RJ-45 serial port
connectors, two RJ-45 Ethernet port connectors, a USB connector (not currently used), and two sets of
indicator lights for up to two radio modules.
The left side of the radio may have I/O connectivity as an option. The radio can be ordered with or
without analog/digital I/O. For radios without integrated I/O the left-side connector is used for
synchronization.
