SNAP910 - 4/10/08

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.
