1.0 Overview
The Nano Series Nano Series is capable of delivering high-performance wireless serial communications in a
variety of network topologies.
The Nano series is available as an OEM modem, as part of a development /interface kit or as a Enclosed mo-
dem. When properly configured and installed, long range communications at very high speeds can be
achieved.
Nano Series modules operate within the 902-928MHz or 2.4000-2.4835GHz ISM frequency bands, using fre-
quency hopping spread spectrum (FHSS) technology. They provide reliable wireless asynchronous data
transfer between most equipment types which employ an RS232, RS422, or RS485 interface.
The small size and superior performance of the Nano Series makes it ideal for many applications. Some typi-
cal uses for this modem:
1.1 Performance Features
Key performance features of the Nano Series include:
•
transmission within a public, license-exempt band of the radio spectrum
1
- this means that the
modems may be used without access fees or recurring charges (such as those incurred by cellu-
lar airtime)
•
transparent, low latency link providing up to 1.2 Mbps continuous throughput
•
communicates with virtually all PLCs, RTUs, and serial devices through either an RS232, RS422,
or RS485 interface
•
supports point-to-point, point-to-multipoint, store and forward repeater, TDMA
•
wide temperature specification
•
maximum allowable transmit power (1 Watt)
•
low power consumption in Sleep Mode (real-time clock wakeup)
•
32 bits of CRC, selectable retransmission and forward error correction
•
separate diagnostics port - transparent remote diagnostics and online network control
•
ease of installation and configuration - the Nano Series utilizes a subset of standard AT-style
commands, similar to those used by traditional telephone line modems
•
3.3V logic level compatibility (Nano OEM models)
