    Introduction to Raven CHAPTER 1 GPRS The AirLink Raven uses serial to connect to a computer or other device and GPRS to connect to Cingular’s cellular network to allow cellular communication to the Internet or other network. Raven Overview The Raven's rugged form factor is ideal for industrial and commercial applications that require real-time communications.

  • Page 10: Chapter 1 Introduction To Raven Gprs

    The Raven has several built in features to make it more effective in a variety of set- tings. In addition, Airlink provides several modem tools to further enhance the capabilities of the Raven. These features and tools are introduced in this User Guide.

  • Page 11: Using The Raven To Connect To The Internet

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

  • Page 12: Common Uses For The Raven

    Introduction to Raven GPRS If you need to contact the Raven, a device connected to the modem, or a host sys- tem 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).

  • Page 18: Chapter 3 Raven Activation

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

  • Page 19: Setup Wizard Menu

    Raven Activation • The Cingular GPRS Raven Quick Start Guide is also available at the AirLink web site. Note: The web site may have a more recent Setup Wizard and Quick Start Guide than those included with your Raven. It is recommended that you check with the web site for the latest version before installing your Raven.

  • Page 20: Configuring The Raven Using At Commands

    Raven Activation Configuring the Raven using AT Commands An alternate method to configure and activate your Raven is by AT commands (full listing beginning on page 61) sent directly to the modem via a terminal application (page 58). This method is recommended only in situations where the Setup Wizard is not available and/or the configuration for the Raven is unusual.You can also con- figure your modem using Wireless ACE (page 15) or AceNet (page 16) using a template built in Wireless ACE.

    For additional information on a specific utility, please refer to the user guide for that utility. These utilities, except AceNet, are free of charge to those who own AirLink modems. You can download them and their user guides from the AirLink web site: http://www.airlink.com/support. Contact your dealer or AirLink for information on AceNet.

    Raven Utilities AceView AceView is a low-profile monitoring tool to view the status of your AirLink Raven and display network status, IP address, RSSI strength, firmware version, and other basic information. You can connect to your Raven locally or remotely using a known IP address or a fully qualified domain name.

    Raven Utilities Wireless ACE and Wireless ACE Web Wireless AirLink Configuration Executive (ACE) and Wireless Ace Web allow you to monitor your Raven remotely. Wireless ACE Web has a web-based interface and covers nearly the same range of features a Wireless ACE. Features discussed in this section apply to both versions unless otherwise noted.

    DNS: Using Names CHAPTER 5 Instead of IPs 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.

  • Page 27: Chapter 5 Dns: Using Names Instead Of Ips

    DNS: Using Names Instead of IPs You can use AT commands (page 61), Wireless ACE (page 15), and ACE Net (page 16) using a template built from Wireless ACE to configure DNS in your Raven. Wireless ACE: DNS FIGURE 1. *DNS1 and *DNS2 - Set these to your primary and secondary DNS servers.

    Keepalive CHAPTER 7 It is not uncommon for your Raven to be disconnected from Cingular 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 Cingular by ping- ing an IP address after a specified period of inactivity.

    Host Modes For example, possible output to the AT command "AT<CR>" (assuming quiet mode is not on) is: PassThru Mode In PassThru mode, the Raven does not behave normally, all serial communication is passed directly between the internal hardware and the computer connected directly to the modem.

  • Page 38: Udp Pad Mode

    Host Modes UDP Pad Mode When the modem is in UDP PAD (Packet Assembly and Disassembly) Mode, all characters received on the serial port are assembled into UDP packets and sent to 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.

The session, started by either method, will be terminated when no data has been sent or received for the S82 period.

  • Page 40: Multicast Udp

    Host Modes 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.

  • Page 41: Tcp Auto Answer

    Host Modes 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).

    Modbus/BSAP CHAPTER 9 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.

  • Page 44: Telemetry

    Modbus/BSAP Configuration Telemetry Telemetry 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.

Containing inputs and outputs sim- ilar to an RTU, PLCs are frequently used for typical relay control, sophisticated motion control, process control, Distributed Control System and complex network- ing. Modbus TCP/IP Modbus TCP/IP simply takes the Modbus instruction set and wraps TCP/IP around it.

    Modbus/BSAP Configuration Configuring the Raven at the Polling Host for Modbus on UDP You can use either Wireless ACE (page 15 and page 57), direct serial communica- tion or Telnet (page 58) to configure the modem using AT commands (page 61). This section covers standard Modbus, variations may need additional commands (AT Commands: page 87).
