CHAPTER 1 Intr oduction to

Raven CDMA

The Raven's rugged form factor is ideal for industrial and commercial applications that require real-time communications. The Raven provides cellular data communications for a variety of applications, such as telemetry, public safety, SCADA, traffic control, traffic metering, transit arrival systems and more.

Introduction to Raven CDMA

CDMA Overview

Code Division Multiple Access (CDMA) provides a digital cellular telephony system provides wireless Internet access at speeds between 60 and 80 kbps, with bursts up to 144 kbps.

Establishing a Internet Connection

The Internet Service Provider (ISP) from you to the Internet is Verizon with your Raven as the connection to Verizon.

When your Raven is powered on, it automatically searches for cellular service using CDMA and establishes a PPP (Point to Point Protocol or “dial” up connection) link to Verizon’s network. As soon as the Raven receives its IP, it’s ready to create a network between your computer or device and Verizon’s network so you can use Verizon to communicate on the Internet.

To use your Raven to connect to the Internet from your computer, you need to connect the computer directly to the Raven’s serial port and use Dial-Up Networking (DUN).

FIGURE 2. Using the Raven to connect to the Internet

Introduction to Raven CDMA

Note: Private network connections are unique for each configu-

ration and not covered as part of the standard installation.

Using CDMA to Communicate with Your Equipment

There are two types of addresses in TCP/IP, dynamic and static.

• Dynamic addresses are assigned on a “need to have” basis. Your Raven might

not always receive the same address each time it connects with Verizon.

• Static addresses are permanently assigned to a particular account and will

always be used whenever your will not be given to anyone else.

If you need to contact the Raven, a device connected to the modem, or a host system using the modem, you need to have a known IP (such as one which is static) or domain name (an IP address which is converted by a DNS server into a word based name).

Raven connects to the Internet. The IP address

Most ISPs (cellular included) use dynamic IP addresses rather than static IP addresses. A dynamic IP address is suitable for many common Internet uses, such as web browsing, looking up data on another computer system, or other client func tion (such as data only being sent out or only being received after an initial request).

Note: If you have a dynamic IP address for your Raven, you can

use a Dynamic DNS service (such as IP Manager coupled with a Dynamic DNS Server, covered later in this User Guide) to trans late a dynamic IP address to a fully qualified domain name so you can contact the

Caution: The IP address given to your Raven by Verizon must

also be Internet routable if the computer you need to connect to the

Raven is not connected directly to Verizon 's IP network. Please check with Verizon to confirm you IP is scheme is correct for your application and needs.

CHAPTER 2 Activation of the Raven

CDMA

Your Raven needs specific parameters before it can operate on the CDMA network. Generally Verizon will provide you with the necessary parameters to get the Raven configured.

Connecting the Raven to your computer

Your Raven’s serial port can be connected directly to most computers or devices using a standard straight through serial cable.

Quick Start Guide and Setup Wizard

The preferred way to configure and activate your Raven is via the AirLink Setup Wizard for Verizon and CDMA. The Quick Start Guide will lead you through the using the Setup Wizard.

• The Raven Setup Wizard for CDMA and Verizon is available from the AirLink

web site, http://www.airlink.com/support.

• The Quick Start Guide is also available at the AirLink web site.

Activation of the Raven CDMA

Note: The web site may have a more recent Setup Wizard and

Quick Start Guide than those included with your Raven. It is rec

ommended that you check with the web site for the latest version before installing your Raven. You will need to look for Verizon, CDMA, and the Raven. Other Setup Wizards may not work to connect you to Verizon.

To run the Setup Wizard, you will need the Microsoft .NET framework and Microsoft Windows 98, Microsoft Windows 2000, Microsoft W indows XP , or later .

• Dynamic IP addresses are granted only when a modem or other device is con-

nected and can change each time the modem or device reconnects to the network.

• Static IP addresses are granted the same address every time the modem or

device is connected and are not in use when the associated device is not con nected.

A dynamic IP address is suitable for many Internet activities such as web browsing, looking up data on another computer system, data only being sent out, or data only being received after an initial request. However, if you need to contact the directly, a device connected to the modem, or a host system using the Raven, a dynamic IP won’t give you a reliable address to contact (since it may have changed since the last time it was assigned).

IP Manager

Fully Qualified Domain Name

A fully qualified domain name (FQDN) generally has several parts.

• Top Level Domain (TLD): The TLD is the ending suffix for a domain name

(.com, .net, .org, etc.)

• Country Code Top Level Domain (ccTLD): This suffix is often used after the

TLD for most countries except the US (.ca, .uk, .au, etc.)

• Domain name: This is the name registered with ICANN (Internet Corporation

for Assigned Names and Numbers) or the registry for a the country of the ccTLD (i.e. if a domain is part of the .ca TLD, it would be registered with the Canadian domain registry). It is necessary to have a name registered before it can be used.

• Sub-domain or server name: A domain name can have many sub-domain or

server names associated with it. Sub-domains need to be registered with the domain, but do not need to be registered with ICANN or any other registry . It is the responsibility of a domain to keep track of its own subs.

A URL (Universal Resource Locator) is different from a domain name in that it also indicates information on the protocol used by a web browser to contact that address, such as http://www.airlink.com.

• .com is the TLD

• airlink is the domain (usually noted as airlink.com since the domain is specific

to the TLD)

• www is the server registered with AirLink.com

• http:// is the protocol (html or web) used to access the webpage for AirLink

Dynamic Name Resolution

When an IP address is not expected to change, the DNS server can indicate to all queries that the address can be cached and not looked up for a long period of time. Dynamic DNS servers, conversely, have a short caching period for the domain information to prevent other Internet sites or queries from using the old informa tion.

16 Raven CDMA User Guide for Verizon, version 2.23

Page 23

IP Manager

If the Raven is configured for Dynamic IP, when the Raven first connects to the Internet, it sends a IP change notification to IP Manager. IP Manger will acknowledge the change and update the DNS record. The changed IP address will then be the address for the

Raven’s configured name.

Once the Raven’s IP has been updated in IP Manager, it can be contacted via name. If the IP address is needed, you can use the domain name to determine the IP address.

Note: The fully qualified domain name of the Raven will be a

subdomain of the domain used by the IP Manager server.

As a free service, Airlink maintains an IP Manager server which can be used for any AirLink modem. The domain is earlink.com and is used in all the samples below.

Configuring the Raven for Dynamic IP

T o configure the Dynamic IP settings in your Raven so that it will use IP Manager, you can use AT commands (page 53), using direct serial communication or Telnet, Wireless ACE ( less ACE.

To configure your AirLink modem to be addressed by name, the mo dem needs to have 4 elements configured.

In Wireless ACE, select Dynamic IP to configure your modem to use IP Manager.

ager. If this is set to zero, the modem will only send an update if the IP changes (i.e. if the modem is reset or is assigned a different IP).

You can configure a second dynamic server as a backup, secondary, or alternate server.

Note: For the Modem Name, you should use something which is

unique but also easy to remember. Your company name or the intended function of the modem are recommended. If you have more than one modem, you can append a number for each.

DNS: Using Names Instead of IP addresses

A domain name is a name of a server or device on the Internet which is associated, generally, with an IP address. In a way, a domain name is like the street address of your house with the phone number being like the IP address. You can contact the house either by going to the address (name) or by calling the phone number (IP address).

Domain Name Service (DNS) is a network service which translates, or redirects, the IP address, allowing someone to contact that address via the name. A DNS server is registered to handle all addresses of a particular domain (much like the post office for a particular town or city is known to the post offices of all other towns and cities and is authorized to give the addresses of locations in its own loca tion).

Configuring DNS

The Raven has an internal DNS resolver with which it can query DNS servers in order to translate names into IP addresss which it can then use internally. Generally, when your Raven receives its IP address from Verizon, it will also be configured to use Verizon’s DNS servers to use for resolving (or translating) names to IP addresses. In that case, the only one which is not overwritten is the alternate DNS.

You can use AT commands (page 53), Wireless ACE (page 10), and ACE Net (page 11) using a template built from Wireless ACE to configure DNS in your Raven.

FIGURE 2. Wireless ACE: DNS

*DNSUSER - Set this, if desired, to an additional DNS server to query first before the primary or secondary (just as a hosts file is queried first on a com puter). If *DNSUSER is set to 0.0.0.0, it will be ignored.

*DNSUPDATE - This command sets how often you want DNS Updates to be forced. Otherwise the up, or the IP address granted by the network changes.

Note: If you will be using your Raven to communicate with

another AirLink modem and both are using IP Manager to translate dynamic IP addresss to domain names, it is recommended that you set *DNSUSER to the IP address for IP Manager. IP Manager’s updates occur more frequently than servers decreasing the time between IP address change and address resolution.

CHAPTER 5 Keepalive

It is not uncommon for your Raven to be disconnected from Verizon after an extended period of inactivity. This is generally a feature intended to reduce your charges for inactive use.

Keepalive is used to test and maintain the Raven’s connection to Verizon by pinging an IP address after a specified period of inactivity. Keepalive is recommended for users who have a remote terminated modem that infrequently communicates to the network. Keepalive is also recommended if you have experienced issues where the modem can no longer be reached remotely.

When Keepalive pings the IP address, an acknowledgement indicates there is an active connection to the network. If the modem does not receive a response from the IP address, it will retry 5 times in 5 second intervals. The the radio module after 5 failed attempts and reconnect to Verizon.

Raven will then reset

Configuring Keepalive

As with all other aspects of the Raven’s configuration, you can use Wireless Ace (page 10), AceNet (page 11), direct serial communication (page 53), or Telnet (page 53) to configure Keepalive.

Raven CDMA User Guide for Verizon, version 2.23 21

Page 28

Keepalive

To set the Keepalive using Wireless ACE, select Other from the menu on the left.

FIGURE 1. Wireless ACE: Keepalive Configuration

*IPPING sets the interval, in minutes, you want Keepalive to test the network connection. To disable Keepalive, set *IPPING to 0 (default setting).

Note: 15 minutes is the minimum time which can be set for Kee-

palive.

*IPPINGADDR sets the IP address you want to use for the test. If *PPINGADDR is left blank or is set to an invalid IP address (i.e. an IP which is unreachable or one which is not a valid IP address), the modem will reset itself on a regular interval.

Data usage using Keepalive

When using Keepalive, be aware that a ping moves approximately 66 bytes of data over the network and is billable by the carrier. The following *IPPING settings will incur approximate monthly data usage in addition to any other data usage:

CHAPTER 6 Host Modes

The Raven plays the part of a host when its serial port is connected to a computer or another device. As the host, the Raven can be in one of six communication modes.

AT: The Raven accepts and responds to standard, Hayes-style AT commands. PassThru: Direct connection to internal hardware (OEM Module) of the

Raven.

PPP: The Raven uses PPP to communicate. SLIP: The Raven uses SLIP to communicate. UDP PAD: Any data received on the serial port is assembled into UDP packets

and send to the session's associated IP and Port (described later). Any responses received from the associated IP and port destined for the modem's Device Port are unwrapped and sent out the

TCP P AD: Any data received on the serial port is packaged into TCP messages and sent to the associated connection's IP and Port (described later). Any data received from the TCP peer is unwrapped and sent out the

serial port.

By default, the Raven is in AT Mode and allows AT Commands to be entered via T elnet (through the serial port connection) or remotely (through the cellular network).

The Raven can be programmed to enter any of the modes, except PassThru, automatically on power up. This is done setting the Startup Mode Default (refer to MD

Raven CDMA User Guide for Verizon, version 2.23 23

Page 30

Host Modes

in the AT Command listing, page 66) to the desired mode. If this setting is nonzero, the modem will enter the specified mode after 5 seconds. If you want to cancel this behavior, the ATMD0 command can be used before the 5-second time-out expires.

If the modem is in any mode other than AT or PassThru, the AT command mode can be re-entered by:

• Deactivating DTR (if &D2 or Ignore DTR, S211, is not set).

• Issuing the +++ escape sequence (if Disable AT Escape, DAE, is not set).

• Resetting or Power cycling the modem.

PassThru Mode can only be exited by resetting the modem.

Note: DTR needs to be asserted (S211=1 or &D0) by the host

before PPP Mode, SLIP Mode, UDP PAD Mode, or TCP PAD Mode can be entered.

AT Mode

AT commands are used to configure the modem, command it to do something, or query a setting. For a full listing of the AT commands, refer to page

AT commands must always be terminated by <CR> (ASCII character 0x0D).

If E=1 (Echo On), the AT command (including the terminating <CR>) will be displayed (output) before any responses.

Two settings affect the format of AT command output: V (Verbose) and Q (Quiet).

If Q=1 (Quiet On), no result codes are output whatsoever, so there is no response generated by a (non query) command.

If Q=0 (Quiet Off), result codes are output. The format of this output is then affected by the Verbose setting.

If Quiet mode is off, the result code is affected as follows:

For V=1 (Verbose mode), the textual result code is surrounded by <CR><LF> and any AT query response is also surrounded by <CR><LF>.

24 Raven CDMA User Guide for Verizon, version 2.23

53.

Page 31

Host Modes

For V=0 (Terse mode), a numeric result code is output with a single trailing <CR> (no <LF> is output), while any AT query response is followed by <CR><LF> (there is no preceding output).

For example, possible output to the AT command "AT<CR>" (assuming quiet mode is not on) is:

<CR> - if V=0 <CR><LF>OK<CR><LF> - if V=1

PassThru Mode

In PassThru mode, the Raven does not behave normally, all serial port communication is passed directly between the internal hardware and the computer connected directly to the modem. This mode can be used to configure hardware-specific set tings (e.g., for provisioning, etc.).

Issuing the "AT\APASSTHRU" enters this mode. The modem responds with OK, at which point a direct connection to the internal hardware is established.

Some internal hardware requires upwards of 20 seconds before AT commands can be entered, so be patient if there seems to be no response to AT commands.

Caution: PassThru can only be exited by resetting or power-

cycling the modem. This mode cannot be entered via a Telnet session.

PassThru Mode allows only specific AT commands. Those commands which are used with ALEOS only will be unavailable. The commands usable also depend heavily on the modem model number (found on the label on the top of the modem).

Caution: ALEOS is disabled in PassThru Mode. You cannot use

most ALEOS specific commands while the modem is in PassThru Mode.

Raven CDMA User Guide for Verizon, version 2.23 25

Page 32

Host Modes

PPP Mode

In PPP mode, the Raven acts as a PPP server, providing an IP address, and DNS servers (if available) to the Host.

PPP mode is entered from the AT mode by using any of the following commands:

AT\APPP<CR> ATDT10.0.0.1<CR> ATDT10001<CR> ATD#19788<CR> CLIENT<CR>

In response to any of the preceding commands, the modem will respond with CONNECT<CR><lf> and is ready for the host to begin PPP negotiations.

The IP received by the host in the resulting negotiation will either be a private (nonroutable) IP or a public (network-routable) IP provided by the network, depending on the settings of *HOSTPRIVMODE. If *HOSTPRIVMODE=1, the value of the private IP an be determined beforehand by querying S110. The private IP to be used can be defined with the command AT*HOSTPRIVIP=192.168.100.33 sub stituting the desired IP address.

AT*HOSTPRIVIP=192.168.100.33Using a private IP insulates the PPP client from changes in IP addresses of the underlying network. The basic NAT-like address translation on all packets.

If a public IP address is being used, any changes in the IP (as determined by the wireless network) will result in the PPP link to the host being disconnected, requir ing the host to reinitiate it. The public IP is passed to the host in the PPP negotiations, so when the network forces a change, the modem has to force the host to renegotiate the PPP link to make this happen.

Slip Mode

SLIP mode is entered be using the "AT\ASLIP" command. As in PPP Mode, the IP address that the host assumes is affected by the setting of *HOSTPRIVMODE.

26 Raven CDMA User Guide for Verizon, version 2.23

Raven will perform

Page 33

Host Modes

SLIP does not negotiate the IP with the host, so before making a SLIP connection, the host SLIP driver must be configured to use the IP specified by querying S110.

UDP Pad Mode

When the modem is in UDP PAD (Packet Assembly and Disassembly) Mode, all characters received on the the Raven’s remote IP address/port, and any packets received from the same IP/ port-destined for the Raven’s Device Port (see *DPORT)--are disassembled and dumped onto the serial line.

A UDP session is initiated by one of the following events:

• Using the Dial UDP (DP) AT command (ex. ATDP192.168.3.23/3456)

• Setting the Startup Mode Default (MD) to 3 (UDP) so that a UDP session is

entered automatically when the modem powers up. Serial data will be sent to the IP/port specified in S53.

• An incoming UDP packet is received and

• UDP auto answer is enabled (S82=2);

• The destination IP address matches that in S53;

• Or allow any IP is set (AIP=1);

• The modem is in AT mode (not in a current UDP or TCP session).

serial port are assembled into UDP packets and sent to

• • • • UDP packet assembly is affected by the values of S50 (PAD Forwarding Time-out) and S51 (PAD Forwarding Character). Data received in the serial buffer will be transmitted when the idle inter-character time-out specified in S50 (in tenths of seconds) occurs or when a character is received that matches S51 (if non-zero).

UDP Auto Answer

UDP auto answer (previously called UDP half-open) is set with S82=2. When set, the

Raven will automatically establish a UDP session to the source IP address and port of the UDP packet received. The Raven will remain "locked" to this one remote IP/port until no data is sent or received for the time interval defined in the UDP auto answer time-out (S83). During this session, packets from other IP/port addresses will be rejected, unless *UALL is set. Whether or not an incoming packet will cause the modem to enter a UDP session is always dependent on the S53 and AIP settings.

Raven CDMA User Guide for Verizon, version 2.23 27

Page 34

Host Modes

When idle, after the time-out has occurred, the Raven is in AT command mode on the serial port, and any valid AT command may be entered during this time.

The Normal UDP Mode (MD3) can be combined with UDP auto answer to cause the incoming serial data to be sent in UDP packets (instead of being treated as AT commands), while allowing sessions to be established from different UDP sources. A UDP session will be initiated either by incoming serial data or by an incoming UDP packet. The session, started by either method, will be terminated when no data has been sent or received for the S82 period. Once the session terminates, another may be initiated by either means.

When the session is initiated by serial data, the new session will be established using the destination address specified in S53. The S53 setting can be changed if the connect to last UDP setting (*UDPLAST=1) is set. The address in S53 will be updated to reflect the address of the last session initiated by an incoming UDP packet. So that when new data is received over the host state, a session will be re-established with the last address. (This behavior is the same as the previous Hybrid2 (MD6) mode).

Note: TCP auto answer (S0) may also be set simultan eously with

UDP auto answer. Then, when in the idle state, the modem will accept either a TCP or UDP incoming packet, and enter a TCP or UDP session as appropriate.

serial port while in the idle

Reliable UDP

Reliable UDP adds a simple protocol on top of UDP to provide reliable deli v e ry of data. When data is received from the host data, containing a message type and a sequence number. The Raven will continue to send this data (buffering any received data in the meantime) until it receives an acknowledgement with this sequence number. If an acknowledgement is not received within the time-out period (specified in S7), the data will be retransmitted. This will continue until an acknowledgement is received or the modem is reset. Likewise any UDP packets received by the header. The Raven will issue an acknowledgement for any valid packets which are received.

Configure the Raven as for a normal UDP session. Set the Startup Mode Default to 3, and the UDP Mode Default to 7 (ATMD73). If using two modems, configure the Destination IP and Port in each to point to each other. Serial data will then be sent reliably between the two

Multicast UDP

Multicast UDP results in any data received from the host serial port being sent to all the clients in the Modbus list. The remote port number is taken from S53. To avoid flooding the network, the packets are sent to each client with a 20ms pause in between. The receipt of UDP packets works as in normal UDP mode (i.e. bound by the value S53 and/or AIP). Since it may take a while to transmit the data to all hosts (especially if all 20 Modbus entries are used and name resolutions are required), new data received from the host port is buffered until current transmissions to all hosts are finished.

Enter the list of target IPs in the Modbus IP list. The index numbers in the IP list aren't used. Configure the Raven as for a normal UDP session. Set the Startup Mode Default to 3, and the UDP Mode Default to 8 (ATMD83). Configure the Destination port to match the device port of the remote modems.

TCP PAD Mode

When the Raven is in a TCP session, all characters received on the serial port are assembled into TCP packets and sent to the mode's remote IP address/port, and any packets received from the remote end of the TCP connection are disassembled and dumped onto the serial line.

• A TCP connection is established by one of the following methods:

• Using the Dial TCP (DT) AT command (for example, ATDT192.168.3.23/

3456)

• TCP auto answer is enabled (S0), a TCP connection request is received, and the

modem is not in a data session.

• Data is received on the serial port and

• The Startup Mode Default (MD) is 4 (auto TCP)

• The remote TCP destination, as defined in S53, successfully responds to the TCP connection request.

Raven CDMA User Guide for Verizon, version 2.23 29

Page 36

Host Modes

The value of S7 (TCP Connection Time-out) specifies the number of seconds to wait, after initiating a TCP connection attempt, for a successful connection to be established. If the connection has not been successfully established before the timeout occurs, ERROR/BUSY is returned.

TCP packet assembly is affected by the values of S50 (PAD Forwarding Time-out) and S51 (PAD Forwarding Character). Data received in the serial buffer will be transmitted when the idle inter-character time-out specified in S50 (in tenths of sec onds) occurs or when a character is received that matches S51 (if non-zero).

The TCP session will be terminated if no data is transmitted or received for the time interval specified in TCPT and TCPS. TCPT is the number of minutes (TCPS=0) or seconds (TCPS=1) used for this idle time-out.

Caution: TCPT should never be 0 when using the TCP mode. A

broken TCP session can result in the modem being left with a TCP half-open connection that can only be terminated with a reset.

TCP Auto Answer

TCP auto answer (S0=1|2) also allows a TCP connection request to be "answered" when the modem is idle, not in a data session. The TCP connection request's desti nation port has to match the modem's device port.

Note: UDP auto answer may also be set simultaneously with

TCP auto answer. Then, when in the idle state, the modem will accept either a TCP connection request or UDP incoming packet, and enter a TCP or UDP session as appropriate.

Hybrid Modes

Some previous hybrid modes (MD=5, 6) are no longer implemented as special, unique modes. Now that UDP auto answer (UDP Half-open, S82=2) can be enabled in conjunction with UDP P AD mode (MD3), effectively this is the same

CHAPTER 7 Modbus/BSAP

Configuration

The Raven supports Modbus ASCII, Modbus RTU, BSAP, and can also emulate other protocols like DF1 or others using its Modbus Variable feature.

Modbus Overview

The Modbus Protocol, developed by Modicon in 1979, provides for client-server (also referred to as master-slave) communications between intelligent devices. As a de facto standard, it is the most widely used network protocol in the industrial manufacturing environment to transfer discrete/analog I/O and register data between control devices.

Modbus, BSAP, and other Modbus variations are often used in conjunction with telemetry devices.

This section is just a brief overview of Modbus. For more information, refer to your Modbus equipment distributor or manufacturer or http://www.modbus.org.

Raven CDMA User Guide for Verizon, version 2.23 32

Page 39

Modbus/BSAP Configuration

Telemetry

T elemetry is an automated communications process by which data is collected from instruments located at remote or inaccessible points and transmitted to receiving equipment for measurement, monitoring, display, and recording. Transmission of the information may be over physical pairs of wires, telecommunication circuits, radios or satellite.

Remote Terminal Unit (RTU)

Modbus was originally designed to be used in a radio environment where packets are broadcast from a central station (also called master or host) to a group of remote units. Each remote unit, Remote Terminal Unit (RTU) , has a hexidecimal identifi cation number (ID). The first part of the broadcast packet contains an RTU ID which corosponds to the ID of one of the remote units. The Modbus host looks for the ID and sends to only the unit with the matching ID. The RTU would then reply back to the central station.

The RTU connects to physical equipment such as switches, pumps, and other devices and monitors and controls these devices. The RTU can be part of a net work set up for Supervisory Control and Data Acquisition.

Supervisory Control and Data Acquisition (SCADA)

Supervisory Control and Data Acquisition (SCADA) describes solutions across a large variety of industries and is used in industrial and engineering applications to monitor and control distributed systems from a master location. SCADA encom passes multiple RTUs, a central control room with a host computer (or network), and some sort of communication infrastructure.

SCADA allows for “supervisory” control of remote devices as well as acquiring data from the remote locations. Pro grammable Logic Controllers allow for a higher degree of automated SCADA.

Programmable Logic Controller (PLC)

A Programmable Logic Controller (PLC) is a small industrial computer which generally monitors several connected sensor inputs and controls attached devices (motor starters, solenoids, pilot lights/displays, speed drives, valves, etc.) according to a user-created program stored in its memory. Containing inputs and outputs sim ilar to an RTU, PLCs are frequently used for typical relay control, sophisticated

Modbus TCP/IP simply takes the Modbus instruction set and wraps TCP/IP around it. Since TCP/IP is the communications standard for the Internet and most net worked computers, this provides a simpler installation. Modbus TCP/IP uses standard Ethernet equipment.

Raven Modbus on UDP

When Ravens are used in place of radios, a Raven is connected to the central station (host) and a Raven is connected to each remote unit. When the Raven is configured for Modbus with UDP, the Raven connected to the host can store a list of IP addresses or names with matching IDs. When the host at the central station sends serial data as a poll request, the Raven at the host matches the RTU ID to a corre sponding IP of a Raven at a remote unit. A UDP packet is assembled encapsulating the RTU ID and serial data transmitted from the host. The UDP packet is then transmited to the specific Raven at the remote unit matching the RTU ID. The remote Raven then disassembles the packet before transmiting the RTU ID and serial data to the remote unit. The remote units operate in normal UDP mode and their data is sent to the host via the remote Raven and host Raven.

Configuring the Raven at the Polling Host for Modbus on UDP

You can use either Wireless ACE (page 10) or direct serial communication or Telnet (page 53) to configure the modem using AT commands (page 53). This section covers standard Modbus, variations may need additional commands.

Port

The destination port for the Raven at the host needs to match the device port in use on all the Ravens at the remote sites. For example, if the remote Raven’s device port (see below) is "12345", then the Modbus host Raven's S53 destination port should be set to "12345".

In Wireless ACE, select Misc in the side menu.

IDs to IPs

The last step of configuring the Raven at the host is setting the IDs to their specific IPs. In Wireless ACE, select the menu option Addr List.

FIGURE 5. Wireless ACE: Addr List

Addresses can be entered in decimal or hex. Wireless ACE will translate hex entries into decimal. The number before the “=” is ID, the number after is the IP address. There can be a total of 100 remote ID/Local addresses entered into the Raven.

When using AT commands via telnet or direct serial connection, use ATMLIST for decimal IDs and ATMLISTX for hexidecimal, ex. if the ID is 27 and the IP is

123.123.123.124, you would enter it as ATMLIST27=123.123.123.124 or

ATMLISTX1B=123.123.123.124.

Dynamic IP

If you do not have a static IP, the host Raven should be configured to report its current IP to a Dynamic DNS (DDNS) server (IP Manager: page 15).

36 Raven CDMA User Guide for Verizon, version 2.23

Page 43

Modbus/BSAP Configuration

In the Host Raven’s configuration, instead of IP address for the Addr List (ATMLIST or ATMLISTX), substitute a single unique name fo r each modem, i.e. remote1, remote2, etc.

When you configure IPManager for the host Raven, make note of your modem name and domain setting in W ire less ACE in the menu select ion Dynamic IP to be used with the remote modems.

Lors de la configuration de IPManager pour le modèle Raven raccordé à l'hôte, dans Wireless ACE, relevez le nom du modem ainsi que le nom de domaine corre spondant à l'aide de l'option de menu Dynamic IP.

CHAPTER 8 Simple Network

Management Pr otocol (SNMP)

The Raven can be configured as an SNMP agent and supports SNMPv2c and SNMPv3.

SNMP Overview

The Simple Network Management Protocol (SNMP) was designed to allow remote management and monitoring of a variety of devices from a central location. The SNMP management system is generally composed of agents (such as your router, a UPS, a web server, a file server, or other computer equipment) and a Network Management Station (NMS) which monitors all the agents on a specific network. Using the management information base (MIB), an NMS can include reporting, network topology mapping, tools to allow traffic monitoring and trend analysis, and device monitoring.

Authentication ensures SNMP messages coming from the agent, such as the Raven, have not been modified and the agent may not be queried by unauthorized users. SNMPv3 uses a User-Based Security Model (USM) to authenticate and, if desired or supported, message encryption. USM uses a user name and password specific to each device.

Raven CDMA User Guide for Verizon, version 2.23 41

Raven, a

Page 48

Simple Network Management Protocol (SNMP)

Management Information Base (MIB)

The management information base (MIB) is a type of database used to compile the information from the various SNMP agents. Reports from various agents, such as the

Raven, are sent as data in form designed to be parsed by the NMS into its MIB.

The data is hierarchical with entries addressed through object identifiers.

SNMP Traps

The trap is a “snap-shot” of the settings and status of the Agent’s device which is sent as a report to the NMS in a form that can be parsed and stored in the MIB. For an example of the trap from an AirLink modem refer to the Append ix,

page 91.

Raven SNMP Configuration

To configure your Raven to work as an SNMP agent, you can use either Wireless ACE, direct serial communication or T elnet to configure the modem using AT commands (page 53). In Wireless ACE, the SNMP commands are all on the Other menu option.

There are only three commands to set for SNMP in the Raven: the listening port, the security level, and the trap destination.

Listening Port

*SNMPPORT sets the port for the SNMP agent to listen on. If set to zero, default,

SNMP is disabled.

FIGURE 1. Wireless ACE: *SNMPPORT

Note: SNMP generally uses port 161, however most Internet pro-

viders (including cellular) block all ports below 1024 as a security measure. You should be able to use a higher numbered port such as 10161.

42 Raven CDMA User Guide for Verizon, version 2.23

Page 49

Simple Network Management Protocol (SNMP)

Security Level

*SNMPSECLVL sets the security level and which version of SNMP communications are used.

FIGURE 2. Wireless ACE: *SNMPSECLVL

0 - No security required. SNMPv2c and SMNPv3 communications are allowed. 1 - Authentication required. SNMPv3 is required to do authentication and

SNMPv2c transmissions will be silently discarded. Authentication is equivalent to the authNoPriv setting in SNMPv3.

2 - Authentication required and messages are encrypted. SNMPv3 is required to do authentication. SNMPv2c and SNMPv3 authNoPriv transmissions will be silently discarded. Authentication and encryption is equivalent to the authPriv setting in SNMPv3.

User Name and Password

The user name is 'user'. The user name cannot be changed. The Raven's password is used as the SNMP password (default is '12345').

Note: The eight-character password requirement for SMNPv3 is

not enforced by the to function. Your SNMP administrator or MIS may require you to change to a more secure and/or longer password.

To change the password in the Raven, select Modem from the top menu line in Wireless ACE.

FIGURE 3. Wireless ACE: Changing the Raven Password - Menu Option

The current password will be pre-entered. As you type the new password and confirm it, the characters you type will be obscured by “x”.

FIGURE 4. Wireless ACE: Changing the Raven Password

For the password, you can use numbers, letters, and/or punctuation.

Caution: The password is case sensitive. “drowssaP” is not the

same as “drowssap”.

Trap Destination

*SNMPTRAPDEST needs to be set with the destination IP and port. If either are set to zero or empty, SNMP traps are disabled.

FIGURE 5. Wireless ACE: *SNMPPORT

Note: Traps are sent out according to the SNMP security level

(i.e. if the security level is 2, traps will be authenticated and encrypted). Currently, the only trap supported is LinkUp.

CHAPTER 9 Har dwar e Installation

Y our AirLink Raven should be mounted in a position that allows easy access for the cables so they are not bent or constricted. The LEDs on the front panel should be visible for ease of operational verification. You should ensure that there is adequate airflow around the modem but that it is kept free from direct exposure to the ele ments (sun, rain, etc.). The exterior of the case should also be grounded.

An optional accessory for your modem is a mounting kit. The bracket is designed to snugly cradle the modem and hold it in place where you need it. Kit” on page 51.

See “Mounting

Connecting the Antenna

APPENDIX 3 A T Commands

Just as with a Hayes compatible analog modem, the Raven parameters can all be configured with AT commands.

Using Wireless Ace

Wireless ACE is a graphical interface for the AT commands and it is highly recommended that you this utility to modify any parameters, however a terminal emulation application, such as Telnet, see below, can be used instead.

With Wireless ACE, you only need to find the command listed and then enter the new value in the space provided. For those commands which have specific param eters, the choices will be in a drop down menu.

Note: Nearly all examples of entering commands in this User

Guide are using Wireless ACE.

FIGURE 1. Wireless ACE: Using AT Commands

To set or commit the changes in the modem, use the Write button at the top of Wireless ACE interface.

FIGURE 2. Wireless ACE: Toolbar

For more information on using Wireless ACE 3G or Wireless ACE Web, please refer to the Wireless ACE 3G User Guide.

Note: Some of the AT Commands are not able to be configured

in Wireless ACE 3G.

With Wireless ACE, you can create a template from one modem and then use that template to configure other modems in the exact same way. You can use a in AceNet, too, to configure several modems the same all at once.

Using Telnet Terminal Emulation

It is possible to communicate with the Raven across a TCP/IP network. Telnet provides a terminal style connection to the Raven.

Most installations of Microsoft Windows come with a version of HyperTerminal (used here for specific directions), but you can use any other Telnet application, such as Putty.

AT Command Tables

The tables below list the AT commands, their parameters, and explain what they do.

• For most commands, you need to preface the command with AT (exceptions are

noted), i.e. ATA which listed as A

Raven CDMA User Guide for Verizon, version 2.23 57

Page 64

• Some commands have specific parameters while other commands will take

whatever your type.

• Acceptable parameters and/or specific formats are in the parameters column.

• Required variable parameters are denoted with italicized text, ex. Dn. The n is

variable and noted in the parameters column.

• Optional parameters are denoted with square brackets [ ].

• Most commands with parameters can be entered with ? to read the current value

(for example, AT&D? will respond with “2” if the default has not been changed).

• AT Commands are not case sensitive. A capital “E” is the same as a lower-case

“e”.

• If you enter a command which is recognized by the Raven, it will respond with

“OK”. If the command is not recognized, the response will be “ERROR”.

• Those commands applicable only to certain model numbers of the Raven will be

noted in the command column.

Caution: Symbols listed with commands, such as *, /, &, or ?,

are part of the command and must be included. Commands with symbols other than * may require PassThru mode.

Note: Some commands may be presented on more than one

table.

Information Commands

Most of the Commands in the “Information and Status” table, only, do not have any parameters. They only provide information. These commands are repeated else where in their respective categories as well.

Local Network and Host Modes

The Local network for the Raven is the one to which it is connected physically via the serial port to your computer, device, hub, or switch. The

Raven has the ability to

provide some NAT (network address translation) to pass communication from the CDMA network and the Internet to the local device(s) and network. On the local network, the

Raven acts as a Host.

PassThru

PassThru Mode is used to communicate directly to the Raven’s internal hardware (OEM module).

MDhh hh (hex byte) =

none AT Escape sequence.

If the Raven is in a data mode (any mode other than PassThru), this command causes the modem to re-enter AT command mode.

Note: There must be an idle time (set by S50) on the serial port before and after this command. The detection of +++ is disabled if DAE=1.

Allow only the IP specified in S53 to connect when UDP auto answer is enabled (S82=2).

Allow any incoming IP to connect when UDP auto answer is enabled (S82=2).

n=1

Always subject to any Friends filters that may be defined.

Half-Open Response - In UDP auto answer (half-open) mode:

No response codes when UDP session is initiated.

n=0

RING CONNECT response codes sent out serial link before the data from the first UDP packet.

n=1

Note: Quiet Mode must be Off. Default power-up mode.

00 - normal mode

01 - SLIP mode 02 - PPP mode 03 - UDP mode 04 - TCP mode 07 - PassThru

TABLE 6. Local Network and Host Modes

Command Parameters Details

S0=n n=0 | 1 | 2 | 3 This register determines how the Raven responds to an

incoming TCP connection request. The Raven remains

in AT Command mode until a connection request is

received. DTR must be asserted (S211=1 or &D0) and

the Raven must be set for a successful TCP connection.

The modem will send a "RING" string to the host. A

"CONNECT" sent to the host indicates acknowledge

ment of the connection request and the TCP session is

established.

0 : Off (Default)

1 : On

2 : Use Telnet server mode on TCP connections.

3 : With a Telnet connection, overrides the client's

default echo, allowing the server on the host port to per-

form the echo. CRLF sequences from the telnet client

will also be edited to simply pass CRs to the server on

the host port. S7=n n = seconds Specifies the number of seconds to wait for a TCP con-

nection to be established when dialing out. S23=[speed],[databits]

*MODEMNAME=[name] name = domain

name (i.e. eair link.com)

Sets the 128-bit key to use to authenticate the IP update

notifications. If the key's value is all zeros, a default key

will be used. If all the bytes in the key are set to FF, then

no key will be used (i.e. the IP change notifications will

not be authenticated). AT*IPMGRKEY1 is used to set

the key to use with AT*IPMANAGER1, while

AT*IPMGRKEY2 is used to the key with

AT*IPMANAGER2.

Sets the number of minutes to periodically send an IP

update notification to the corresponding server . This will

occur even if the IP address of the Raven doesn't change.

*IPMGRUPDATE1 is used to set the refresh rate to

*IPMANAGER1, while *IPMGRUPDATE2 is used

with *IPMANAGER2.

If the value is set to 0, then periodic updates will not be

issued (i.e. IP change notifications will only be sent

when the IP actually changes).

Name of the Raven (up to 20 characters long) to use

when performing IP change notifications to IPManager.

The value in *DOMAIN provides the domain zone to

add to this name.

Example: if *MODEMNAME=mymodem and

*DOMAIN=eairlink.com, then the modem's fully qual

ified domain name is mymodem.eairlink.com.

Note: Each modem using IPManager needs a unique

name. Two modems cannot be called “mymodem”. One

could be “mymodem1” with the other as “mymodem”.

Automatically Generated Names:

#I3 - The ESN/IMEI will be used as the name.

#NETPHONE - The phone number be used as the

name.

Note: Only letters, numbers, hyphens, and periods can

be used.

TABLE 16. Modbus Settings

Command Parameters Details

RKEY=n n= 0 or Radio Transceiver Keying.

0 : Off (Default) 1 : On

Enable/disable MDS Radio transceiver keying. Radio keying is designed to assert CTS when a packet is received, delay the time as specified, send the data out the serial port, wait the same amount time, drop CTS. This way, the CT S signa l can be used to key a transmit ter on and give it time to reach its power level before data is sent to it. Delay interval is specified in S221.

Cannot be configured in Wireless ACE.

SNMP (Simple Network Management Protocol)

Simple Network Management Protocol (SNMP) can be used to monitor devices connected to a network for any conditions which warrant administration attention. By default, SNMP uses port 161, however most Internet providers (including cellu lar) block all ports below 1024 as a security measure.

TABLE 17. SNMP

Command Parameters Details

\ACEPW=pw pw=password Change the ACE password to a new value. Password is

case-sensitive. Default password is 12345.

Example: AT\ACEPAW=new123 *SNMPPORT=n n=0-65535 This controls which port the SNMP Agent listens on.

0 : SNMP is disabled.

Port for SNMP agent to listen on. *SNMPSECLVL=n n=0 | 1 | 2 Selects the security level requirements for SNMP com-

munications as follows:

0 : No security required. SNMPv2c and SNMPv3 com-

munications are allowed.

1 : Authentication equivalent to 'authNoPriv' setting in

SNMPv3. SNMPv3 is required to do authentication,

SNMPv2c transmissions will be silently discarded.

2 : Authentication and encryption, equivalent to 'auth-

Priv' setting in SNMPv3. SNMPv3 is required to do

authentication and encryption, SNMPv2c and SNMPv3

authNoPriv transmissions will be silently discarded.

*SNMPTRAPDEST=host/ [port]

host=IP address port=TCP port

Messages are both authenticated and encrypted to pre

vent a hacker from viewing its contents.

Controls destination for SNMP Trap messages.

If port is 0 or host is empty, traps are disabled.

Traps are sent out according to the SNMP security level

(i.e. if the security level is 2, traps will be authenticated

and encrypted). Currently, the only trap that can be gen

erated is linkup.

SMTP/SMS

SMTP (Simple Mail Transfer Protocol) is the de facto standard for email transmission across the Internet. The Raven can send messages using SMTP if it has been configured to use a mail server.

SMS (Simple Message Service) is another way to send messages via your Wireless Service Provider’s cellular network.

86 Raven CDMA User Guide for Verizon, version 2.23

Page 93

Caution: Your account with Verizon may not support message

sending. For most SMS commands (those not preceeded by *), you will need to have the modem in PassThru mode.

account (*SMTPFROM) with the server (*SMT PADDR).

Note: Not required to use SMTP settings but may be required by carrier.

Sends an email to the address specified, followed by the body of the email message.

The email message is terminated and sent by entering a . or Ctrl-Z on an empty line.

See also *SMTPSUBJ, *SMYPFROM, and *SMTPADDR.

(*SMTPSEND). If no status is available 0 is returned. Once read, the status is cleared out.

The status codes are received from the SMTP server the modem attempted to send the request.

Example: 354 = send in progress, 250 = sent ok. Allows configuration of the default Subject to use if one

isn't specified in the message by providing a "Subject: xxx" line as the initial message line.

is entered. E-mail is only available if

*NETSMS2EMAIL has been configured correctly.

The message is terminated and sent by entering Ctrl-Z

on an empty line.

New Urgent Msg {Index = 1}: <n>

New Regular Msg {Index = 2}: <r>

Voice Messages {Index = 3}: <v>

The Index number corresponds to the SMS list index

used to retrieve messages. The counters n, r, and v indi

cate the number of messages in each list.

When retrieving (!GSMS) or deleting (!DSMS), the

message number is base 0, so the highest message num

ber in any list is the reported count minus one.

Note: There is no confirmation required. Use this with

caution.
