For our Customers who wish to use this product in hazardous locations.
This SNAP2410 has been tested by Underwriters Laboratories Inc. for use in Class I, Division 2,
Groups A, B, C, and D Hazardous Locations as specified in UL1604 and UL/C-
UL/Zones(UL2279).
Such areas may have Explosive Gases.
To install this radio in this environment the following steps must be implemented.
1) The power supply used with the product must be a UL Class 2 rated device.
2) Contract a Qualified Licensed Electrician to install and run the power wiring from a
screw type, hard wired 12 VDC 1A Class 2 Output power supply in a UL Listed Box
and route a conduit to the radio which must be installed in a UL Listed Box suitable
for the environment. The conduit must be gas tight so no gases can flow through
conduit.
3) Any Murata products with outdoor radio transceivers (tower mounted) marked for
Hazardous Locations must have the interconnecting multi-conductor cable run in
approved conduit for the location. The cable must be in the conduit until out of the
Hazardous Location and the conduit must be gas tight so no gases can flow through
conduit.
4) Do NOT remove the power connector to the device while circuit is live. Disconnect
power only while circuit is dead, or the location is known to be non-hazardous.
Failure to do so, may result in a “Risk of Fire or Explosion”
Only then is the unit suitable for a hazardous location.
For more information on Hazardous Locations contact UL and ask for UL1604
requirements. www.ul.com
RF Exposure
Repairs
WARNING: End Users of these systems must be informed that RF exposure limits
may be exceeded if personnel come closer than 45 cm to the antenna aperture when
exceeding 9 dBi of gain in conjunction with the transceiver.
Murata does not recommend field repairs of the radio equipment. Surface Mount
Technology (SMT) has been used in the production of the transceiver module, which
requires specialized training and equipment for proper servicing. The equipment
should be returned to the factory for any repair.

INTRODUCTION
The SNAP2410 from Murata provides Ethernet connectivity to networks of WIT2410 serial
radios. Built around the WIT2410, the SNAP2410 provides a 10/100BaseT connection to
Ethernet networks and functions as base stations for remote devices containing WIT2410
transceivers. The SNAP2410 allows non-Ethernet serial devices to appear as Ethernet devices to
network-based applications.
Each SNAP2410 can support 60 simultaneous remotes. Each remote radio has a unique ID
number, so the number of remotes that can communicate with a SNAP is unlimited, subject to a
limit of 60 remotes at any one time.
The communication between the SNAP and the WIT2410 remotes is performed using the
WIT2410 over-the-air protocol. Thus the SNAP products are 802.3 compatible but not 802.11b
compatible. By using the 460Kbps over-the-air data rate and the WIT2410 protocol, the full
range of WIT2410 radios is realized, three times the range of most 802.11b products.
The SNAPs enjoy the same benefits of frequency-hopping spread spectrum technology that the
WIT2410s do. Namely, the immunity to multipath fading and resistance to jamming that is
provided by changing frequency every few milliseconds. Operating in the 2.4GHz ISM band,
SNAPs can be used license-free.
The SNAP has three modes of operation, TCP/IP, UDP and PPP. The default mode is the TCP/IP
mode. In TCP/IP mode, the SNAP acts like any other network access point as either a client or
server device. This allows standard WinSocket® routines to be utilized. Remote devices are
setup to be identified by either an IP address or by a port number under the IP address of the
SNAP. The remote devices send and receive unformatted data to and from the SNAP which
performs the encapsulation and de-encapsulation of the unformatted data into and out of Ethernet
datagrams.
The UDP mode is similar to the TCP/IP mode with remotes operating as clients. This mode
supports the connection-less UDP protocol.
The PPP mode is intended for applications where the remote device is equipped with a PPP
client. In these applications, the SNAP functions as a PPP host providing Internet Access to the
remote devices.

GETTING STARTED
The SNAP2410 is easy to install and operate. In most instances, the only installation steps will
be setting IP addresses and connecting the antenna, power and Ethernet cable.
Setting up a SNAP2410 requires the following steps:
•Enter an IP address into the SNAP
•Configure the SNAP to act as a client to a server-based application or to act as a server to
a client workstation.
•Set remote WIT2410 devices to be identified to the application as individual IP addresses
or port numbers.
The default settings in the SNAP are sufficient to allow connection to Ethernet networks and to
have remote WIT2410 devices connect with the SNAP. Other steps you may want to take
include:
•Enter a default route IP address if data is to be sent off the SNAP’s subnetwork (See
Ethernet Commands)
•Change the network number (See Radio Commands)
Instructions on setting up the SNAP are detailed in the Configuring the SNAP section of this
manual. Details on the various operating modes and configurations can be found the SNAP
Operation section.

The antenna connector is a reverse polarity TNC type connector. An antenna may be connected
directly to this connector. Alternatively, an antenna may be located away from the SNAP using
RF cable to connect the SNAP to the antenna. Murata does not recommend using RF cables
longer than 5 feet. If more distance is required between the SNAP and the antenna Murata
recommends using the SNAP2410X. If the SNAP2410X is not used, high-quality, low-loss RF
feed line must be used.
The 10/100BaseT Ethernet connector is the standard RJ-45 connector. The connector is wired to
be able to connect directly to an Ethernet hub using a cross-over cable. If it is desired to connect
the SNAP directly to a PC without a hub, the SNAP must be connected with a straight through
cable. (Both cables are provided.)

The synchronizing signals are provided for special applications where multiple master SNAPs
are employed. The synchronizing signals are RS-485 levels and may be connected using an RJ-
11 connector. SNAPs will automatically determine which SNAP will generate the sync signal.
See the section Synchronization for details. In most instances the synchronizing signals are not
required and may be left unconnected.
The power connector is a 2-pin DIN type connector. The provided AC adapter provides a 12 volt
power level to the SNAP. The SNAP can accept DC voltages ranging between 9VDC and
26VDC if alternative power supplies are to be used.
The Configuration Port is an RS-232 serial port that may be used to configure the SNAP. This is
useful when the default IP address of the SNAP cannot be used with the existing network
preventing configuration through a telnet session. See the section Configuring the SNAP for
details of using this port.
SNAP Status Indicators
The PWR indicator on the front panel indicates that power is applied to the SNAP. A flashing
LED indicates the SNAP is executing the built-in memory test.
TXD and RXD are indicators of data activity. They indicate the transmission and reception of
data over the Ethernet connection. Note that these LEDs can be active even when the SNAP has
no remote radios registered.
The LINK indicator when illuminated indicates a good connection to the Ethernet network. If
this LED is not on, it can indicate a cross-wired connection between the SNAP and the network.
It may also indicate a faulty cable connection.
The RF LINK LED indicates a socket connection has been established.
The RF XCVR indicator (X version only) when illuminated, means the SNAP is communicating
properly with the external radio.
