Point
Designed for use as a base station for WIT910-based products, the SNAP910 provides seamless Ethernet
connectivity for remote serial devices. The SNAP910 connects up to 15 WIT910 wireless remotes to a 10/
100Base-T Ethernet network. The SNAP910 also is ideal for use as access points for a network of RFM HN-
91 Series modems. Multiple SNAPs can be co-located to support larger numbers of remote devices. Certified
by the FCC, the SNAP910 can be used license-free in the US.

Ethernet Connectivity
The SNAP910 allows limited intelligence or legacy serial devices to transmit unformatted serial data to an application residing on an Ethernet network. Each
remote device can be treated as an Ethernet device by the application even though the remote device sends and receives unformatted serial data. The
SNAP910 handles all IP or port assignments as well as encapsulating and un-encapsulating unformatted data into and out of Ethernet datagrams.
Scalable
SNAP family members have an integral WIT910 radio module providing 172.8Kbps throughput for up to 15 remotes. Multiple SNAPs can be deployed to
provide communication for more remote devices.
Versatile
Configuration of the SNAP family is through a standard RS-232 serial port using the RFM WinSNAP Windows™-based software. Alternatively, the SNAP
may be configured through a Telnet session. The system designer is given the freedom to choose the wireless communication parameters that provide the
optimum performance for each application. Point-to-point and point-to-multipoint modes are supported using a dynamically assigned TDMA mode.
Long Range
The RFM 900MHz spread spectrum, frequency hopping radios have a demonstrated 20+ mile range using omni-directional antennas, making the SNAP910
ideal for a variety of long range applications. For applications requiring more antenna gain, the SNAP910X replaces the omni-directional antenna with an
external reverse TNC connector.
Reliable
The SNAP910 family provides both reliable communication and reliable operation. With frequency hopping spread spectrum technology, the SNAP
provides immunity to jamming as well as immunity to multipath fading. Using automatic retransmit request (ARQ), transparent error-free communication is
automatic. The built-in data scrambling adds a measure of security. And reliable operation is assured through our stringent QA processes.
