  • Page 15: Led Indicators

    Power and GPS On = On during startup of ZyWAN. Slow blink = ZyWAN is running, but there is no GPS lock. (Slow blink is approximately one blink every 2 seconds.) Fast blink = ZyWAN running, and GPS position lock obtained.

  • Page 16: Power Connector

    Power Connector The ZyWAN can be powered from 10 to 26 VDC. Power to the ZyWAN is supplied via the 4-pin power socket (mating connector: Kycon KPPX-4P plug). The power plug must be inserted with the flat part of the plug facing up (toward the top of the ZyWAN front panel).

  • Page 17: Antenna Connections

    PART 1: GETTING STARTED Antenna Connections The “CELL” connector on the front of the ZyWAN is typically a standard polarity SMA (female) connector. The cellular antenna to be connected here must be rated for operation within one or more of the ranges required by the ZyWAN model/cellular type, as given in the following table.

  • Page 18: Serial Ports

    In RS-485 or RS-422 systems, the ground connection is optional. Typically, it is used to connect the cable shield for a shielded, twisted pair cable. In the ZyWAN, the RS-485/422 ground is common with the RS-232 grounds, but it is isolated from the metal case. In order to avoid ground loops, connect the cable shield to the RS-485/422 GND AT ONLY ONE POINT in the network.

  • Page 19: Usb

    An older WiFi option used the bottom USB port internally, but the WiFi option now uses an internal PCMCIA card. If the ZyWAN includes either of these hardware options, the external USB socket will be plugged to indicate the port is in use, and it must not be used for external equipment.

  • Page 20: Sim Card

    SIM Card The ZyWAN for a GPRS, 3G, or IDEN network requires a SIM card from the network provider in order to operate on the cellular data network. The SIM card is accessible through an access panel on the bottom of the ZyWAN.

  • Page 21: Battery Link

    The ZyWAN contains a coin-type replaceable Lithium battery (CR2032, 3V) to maintain its real-time clock when input power is removed. A user jumper on the main circuit board enables this battery. The ZyWAN is normally shipped with the battery jumper connected. If the unit will be sitting unused for lengthy periods of time (months or years), it is recommended to remove the jumper to extend the life of the battery.

  • Page 22: Chapter 2 Accessing The Zywan

    What You Will Need Hardware Requirements The ZyWAN must be connected to a stand-alone computer and/or a network, so that the initial configuration may be loaded via the Web configuration page.

  • Page 24: Serial Connection To Com1

    Serial Connection to COM1 The COM1 port of the ZyWAN is used for a serial console. Typically, this allows a local administrative (‘root’) login to the ZyWAN using a null modem serial cable. The next section describes the settings for Windows HyperTerminal.

  • Page 25: Setting Up Software

    Windows HyperTerminal Windows provides a serial terminal program, HyperTerminal, for serial communications. This can be used to access the console port of the ZyWAN for diagnostics. The following steps are the setup instructions for Windows HyperTerminal. 1. In the Windows Start menu, select Programs>Accessories>Communications>HyperTerminal. The Connection Description window is displayed.

    PART 2: SOFTWARE CONFIGURATION Chapter 10 Update The following screen capture shows the Update tab. The Update tab on the Web interface provides one method to update the ZyWAN firmware to a later version. See the following section, Updating Using WinSCP on page 106, for a more recommended method of updating, especially for systems where the default network is a cellular or private network.

  • Page 106: Updating Using Winscp

    Updating Using WinSCP Several of the version updates for ZyWAN are fairly large. For this reason, it may not be recommended to use the Web interface described above because of the cost or length of time it requires to load files over the cellular network.

After the files are loaded, connect to the ZyWAN using either HyperTerminal on the COM1 diagnostics port or over the network using PuTTY (or another SSH application). See the section Setting Up Software page 25, for help setting up HyperTerminal or PuTTY.

Once the reboot has finished, the system has been updated to version 1.7. This can be verified on the Web configuration page or by typing the command cat /home/arcom/version.txt (The response should be ‘7’.)

  • Page 112: Chapter 12 Backing Up Configurations

    The Web configuration page is the main way to implement configuration changes on the ZyWAN. However, it may be useful to be able to copy configuration files from the ZyWAN, either to install on a multiple devices or to save for archive purposes. This section describes the process of retrieving configuration files from the ZyWAN and loading them onto a different ZyWAN.

    The actual implementation may vary with customer requirements. The configurations described in this section are only a subset of the functionality of the ZyWAN. Many other configurations are possible that are not represented by the examples included in this section.

    UDP ports 67 and 53 (DHCP and DNS) are allowed in the ZyWAN firewall, and NAT is configured for eth0 and wlan0. The next sections provide detailed descriptions including Web configuration pages for each setting.

    Do not configure the Default Gateway and DNS Server addresses because these addresses will override the cellular network. If configured, the Default Gateway address will be the ZyWAN’s default route, and the ZyWAN will obtain its public DNS servers from that network.

    Do not configure the Default Gateway or DNS Server addresses because these addresses will override the cellular network. If configured, the Default Gateway address will be the ZyWAN’s default route, and the ZyWAN will obtain its public DNS servers from that network.

  • Page 118: Networking Setup

    Networking Setup Port 67 (UDP) is required for the ZyWAN to act as a Default Gateway to other devices, and port 53 (UDP) is required for it to act as a DNS server. The NAT entries allow devices on each network to route through the ZyWAN to reach the cellular network (ppp0 interface).

    This example also shows the use of COM2 (RS-232) at a baud rate of 19,200, which must be set correctly for the application. If RS-485 is needed (on an appropriate model of ZyWAN), use COM3 with ”Flow Control” set to RTS/CTS and “Echo cancel RS485” set to Yes. See...

  • Page 123: Configuration Example 4: Gps Interface

    GPS data requires the cellular account to have a static, public IP address. GPS Setup The GPS Terminal Server allows incoming TCP connections to be made to the ZyWAN to obtain raw NMEA data from the GPS module. The desired NMEA messages may be enabled. This NMEA data may also be sent to a local COM port.

  • Page 124: Networking Setup

    The portions of the Networking configuration page shown are used to enable inbound connections to the Terminal Server port 5000 (TCP). The NTP setting allows the ZyWAN to obtain the correct system time, so GPS reports sent with UDP will contain the correct timestamp.
