Page 7: Introduction
WIT2411 transceivers. The SNAP2411 allows non-Ethernet serial devices to appear as Ethernet devices to network-based applications. Each SNAP2411 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. -
Page 8: Getting Started
SNAP2411 GETTING STARTED The SNAP2411 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 SNAP2411 requires the following steps: • Enter an IP address into the SNAP •... -

SNAP2411 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. -

SNAP2411 SNAP2411DX Figure 7 shows the SNAP2411DX and the remote radio assembly. Connection between the SNAP2411X enclosure and the remote radio assembly is made through the 15-pin remote radio connector on the front of the SNAP2411X. Digital signals, rather than RF signals are sent over the connecting cable which may be up to 300 feet in length. -
Page 17: Attaching The Data/Power Cable Connector
SNAP2411 The Console port is an RS-232 serial port that may be used to configure the SNAP. Connection to this port is made with the 9-pin to RJ-11 serial cable included with 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. - Page 18 SNAP2411 If a pin is accidentally installed in the wrong connector location, simply loosen the screw, remove the pin, re-insert it into the proper location hole and tighten the screw. Use the following color code to insert the pins into the connector:...

Page 19: Configuring The Snap
SNAP2411 CONFIGURING THE SNAP SNAPs are shipped from the factory with no IP address, no DNS address and no route or gateway address specified. If a BOOTP or DHCP server is not present an IP address must be assigned to the access point before connecting it to a network. To allow IP traffic to leave the... -
Page 20: European Union Settings
The transmit power of the SNAP2411 in the default mode is 18dBm. Thus the supplied antenna meets the EU limit. If gain antennas are to be used, the low power setting of the SNAP2411 must be selected. This setting sets the transmit power at the antenna connector to 10dBm. In this setting a maximum of 10dB of antenna gain may be used. - Page 21 SNAP2411 This parameter will take effect immediately and will be saved into memory for use when power is cycled. © 2000- 2004 Cirronet™ Inc M-2411-0012 Rev -...

Page 22: Snapcom Utility
SNAP2411 SNAPCOM UTILITY SNAPCom is a simple TCP/UDP utility program to help familiarize the user with the SNAP and its operation. SNAPCom can be executed off the CD or copied onto a PC. There is no need to install the program. SNAPCom is not a configuration utility and assumes the SNAP has previously been configured using WinSNAP and/or a telnet session. -
Page 23: Tcp Server Operation
SNAP2411 SNAPCom window. A Transmit button will appear only when a socket has been established with a remote device. Data can be sent to the remote by entering the data in the Transmit Information window and clicking on Transmit. When multiple remotes have opened sockets with SNAPCom, specific remotes can be selected for transmission by selecting their IP address from the pop-down IP address menu. -
Page 24: Udp Operation
SNAP2411 UDP Operation UDP is a “connection-less” protocol that requires no handshaking between devices before transmitting data. As such, there is no verification through the UDP protocol that a transmission was successfully received. The benefit of UDP is the simplified protocol stack that is needed to implement it. - Page 25 SNAP2411 Received data will be displayed in the main SNAPCom window. © 2000- 2004 Cirronet™ Inc M-2411-0012 Rev -...

Page 26: Snap Operation
SNAP2411 SNAP OPERATION Overview At the most basic level, SNAPs can be thought of as Ethernet-to-serial interface adapters. That is, they take data from a host application over a 10/100BaseT Ethernet connection, remove the Ethernet header information, format the data for WIT2411 radios and transmit the data to the on- board WIT2411 through a high-speed serial interface. -
Page 27: Synchronization
SNAP2411 Synchronization Synchronization is only required when multiple SNAPs are co-located. This allows the co- located SNAPs to transmit at the same time and listen to remotes at the same time. This reduces interference between SNAPs that would occur if one SNAP was transmitting when a co-located SNAP was listening to remotes. -
Page 28: Snap System Commands
SNAP2411 SNAP System Commands The SNAP supports a series of commands that allow for configuring the Ethernet interface as well as the radio parameters of the on-board WIT2411. These commands can be entered during a telnet session or by using the WinSNAP utility when the prompt is displayed. -

SNAP2411 route Displays and manipulates gateway IP addresses to route IP traffic off the subnet. Default sets the default gateway IP address. When an IP address is entered instead of default, the gateway IP address specified will be used only for traffic destined for that IP address. -
Page 31: Radio Commands
SNAP2411 Radio Commands The “radio” command provides access to several sub-commands that are useful in configuring the WIT2411 in the SNAP. The command can be used to display the banner radio banner from the radio. This is useful in determining the unique ID of the radio and the version of firmware running in the radio. -
Page 32: Tcp/Ip Mode Operation
SNAP2411 TCP/IP MODE OPERATION The default operating mode of the SNAP is the TCP/IP mode. In this mode, the command line prompt is If the command prompt is , it is an indication the SNAP is in the PPP mode TCP>. -
Page 33: Server Mode
SNAP2411 device, it will be transmitted to the server over this socket. Data to be sent to the remote device is sent to the SNAP over the same socket. The SNAP determines to which remote device the data is intended and translates the IP address or port number to the correct radio ID. -
Page 34: Assigning Remotes Ip Addresses
SNAP2411 Assigning Remotes IP Addresses Remote devices can be identified to applications by either an IP address or Port number. Remote devices can have IP addresses assigned in one of three ways: dynamic assignment by the SNAP, static assignment by the SNAP, or by a DHCP server. -
Page 35: Assigning Remotes Port Numbers
SNAP2411 where remote-id is the radio serial number with hyphens between each two digits as in the above example. To use a DHCP server to assign IP addresses to remote devices, the ipbase must be set to 255.255.255.255. Set the ipbase as above using the... -

The command turns on a connect message whenever a remote registers with the SNAP.
-
Page 38: Udp Mode Operation
SNAP2411 UDP MODE OPERATION The UDP mode of the SNAP operates similar to the TCP/IP mode when the remotes are acting as clients. The assignment of IP addresses and/or port numbers to remotes is accomplished using the same commands as in TCP/IP mode. The UDP commands are identical in function to the TCP/IP commands but are repeated below. - Page 39 SNAP2411 help Displays the help screen listing of the commands. control Displays and sets the port to be used to send remote connect messages to a client or server application. remote Displays and manages table of remotes registered with the SNAP. Allows static IP address assignment on a per remote basis.

Page 40: Ppp Mode Operation
SNAP2411 PPP MODE OPERATION The SNAP can be configured to operate as a PPP (Point-Point Protocol) server. PPP is a dial-in network connection that allows TCP/IP communication. A PPP connection allows a remote connected to a computer to be connected to network that the SNAP is on using the TCP/IP protocol. -
