Summary of Contents for ControlByWeb XW-110

  • Page 2 Notes: The XW-110-Plus is generally identical to the XW-110 but has additional features and capabilities. The differences are noted in Section 3. The screen images throughout this manual are for the XW-110-Plus version. The settings however, are generally identical to the XW-110 except where noted.

  • Page 3: Section 1: Introduction

    Only use batteries to provide backup power, or for modes where the web server is not being used. If the internal web server is enabled in the XW-110, the unit will need to be powered by an external wall transformer.
  • Page 4 ➢ Send encrypted emails. ➢ Temperature data can be logged and periodically send to an email account for long-term storage ➢ The XW-110-Plus includes auxiliary protocols including XML, Modbus/TCP and Remote Services ➢ Simple and easy to use ➢ 5-year warranty 1.1.2 Part Numbers and Accessories...
  • Page 5 The XW-110 should not be used in situations where failure to transmit or receive data could result in damage to property, equipment, direct, indirect, consequential, or incidental damage, including damage for loss of business profit, business interruption, loss of data, life, and the like.

  • Page 6: Section 2: Installation And Setup

    Section 2: Installation and Setup 2.1 XW-110 Temperature Sensor Connections The XW-110 uses “1-Wire” digital temperature sensors. The XW-110 supports one sensor and the XW- 110-Plus supports up to three sensors. The sensors are interchangeable and require no calibration. The sensors accuracy is +/-0.5°C (-10°C to +85°C).
  • Page 7 Many factors can determine the maximum length of the cable, including the sensor network topology, the type of cable used, the number of sensors and ambient electromagnetic noise. Multiple sensors can be connected to the XW-110 Plus in two ways: directly connected (star topology) or “daisy chained” (linear topology), shown below.

  • Page 8: Power / Batteries

    2.2 Power / Batteries The XW-110 is powered from either a 5-volt DC wall transformer or two internal 1.5V “AA” batteries. If the wall adapter is connected, no power is drawn from the batteries. If the external power fails the module automatically switches to the internal batteries.
  • Page 9 Although using this method to connect the XW-110 to the network is simple, you will not be able to access the XW-110 web server unless you know the IP address that was assigned by the DHCP sever (router) or unless mDNS services are available on your device.
  • Page 10 If you need to access the XW-110 using its internal web server you will need to obtain the IP address that was assigned to the XW-110 through your DHCP server or router. Alternatively, if using an mDNS capable device, it may be accessed by entering the appropriate URL into the address bar of your web browser: http://xw-110.local/setup.html...

  • Page 11: Application Examples

    Once all the appropriate settings have been applied, click on the Reboot button, the XW-110 will reboot and begin low power operation. The XW-110 will no longer broadcast an SSID and the web page will no longer be accessible. The XW-110 will periodically awaken, measure the temperature and check for an alarm condition.
  • Page 12 The XW-110 is workable for this application with the default settings, no further settings are needed. Note, only one device can be connected to the XW-110 at a time when it is in the Access Point mode. The XW-110 will continue to broadcast an SSID and you can connect to the XW-110 anytime with your smart phone and view the temperature on the Control page (http://192.168.1.2).
  • Page 13 The freezer is within range of a WiFi access point. The HTTP web server is disabled to provide long battery life. Mount the XW-110 on a wall next to the freezer. Use an X-DTS-S3C temperature probe to monitor the temperature inside the freezer. The XW-110 will not work inside the freezer because the WiFi radio signal will not propagate thru the metal walls and the low temperature would severely diminish the battery capacity.

  • Page 14: Section 3: Web Server

    If the XW-110 has been added to a network using WPS, it will use DHCP and you will need to use the IP address assigned to it. This can be found in the DHCP server, or by using mDNS. The mDNS name is http://xw-110.local/ for the XW-110 and http://xw-110p.local/ for the XW-110-Plus.
  • Page 15 X-600M™. The XW-110-Plus is targeted for stand-alone applications and the “Slave” mode is not available with the XW-110-Plus version. The Mode setting will not take effect until the XW-110 is rebooted. To do this click the Reboot button after making a change to the Mode.
  • Page 16 This is the current product revision of the internal software Serial Number This is the serial number of the XW-110. The serial number is also the MAC address of the unit. Power Supply This field shows if the XW-110 is currently being powered by batteries or the DC wall transformer. The battery voltage is periodically measured and an estimate is made of the remaining battery life.
  • Page 17 SSID The SSID (Service Set Identifier) is the name of your WiFi network. Click the Refresh button to make a fresh scan of available networks. Note: The Refresh button is inactive if the XW-110 itself is an access point. Security Type of authentication used by the access point for connections.
  • Page 18 Use DHCP This option allows DHCP to be enabled or disabled. If this option is set to Yes, the XW-110 will wait for an IP address from a DHCP server each time it is powered. The default setting is No (this is recommended for most installations).
  • Page 19 It is an open protocol and offers interoperability with software and devices from other manufacturers. This is enabled by selecting Yes in this field. The default setting for this field is No. (See Section 5.1: Modbus Operation for more information on using XW-110 on a Modbus network.) Note: Modbus communications are disabled whenever the Control Password is enabled as Modbus does not have support for Passwords.
  • Page 20 This option enables encryption of the remote services connection with the remote services server as well as authentication of the XW-110 to the server by a client certificate and key. Custom certificates and keys can be loaded into the XW-110 for this purpose. (See Remote Services at the end of this section for more information.) By default, the XW-110 does not come with any SSL certificates already installed.
  • Page 21 Client Certificate. Care should be taken with where this client key is stored as it is meant only to be known to the XW-110. To upload a custom client key to the XW-110, click the Browse button, find the PEM formatted file, and select Submit.
  • Page 22 XW-110 must have a properly configured network connection and a SMTP server must be defined. Emails only work if the XW-110 is connected to an access point and can send messages on the internet. The XW-110 Plus contains additional settings than the XW-110. If you have the XW- 110, your screen may differ slightly.
  • Page 23 Email on AC Power Fail (XW-110-Plus only) When enabled, the XW-110-Plus will send a status email when it detects loss of the +5V input power source. This feature only works if batteries are installed and power to the access point and internet is still available.
  • Page 24 Note: When the XW-110 is in Access Point mode, your smart-phone or computer connects directly to it and the XW-110 is not connected to the Internet. In this mode, no email messages can be sent and the Test Email button is disabled.
  • Page 25 (pushes) the data to a remote server (usually another ControlByWeb device). This tab is used to set which server the data is to be sent and how. No alarms or emails are supported and the web server is disabled.
  • Page 26 Web Server XW-110™ WiFi Temperature Sensor Users Manual defines the location of a script or page that can accept the data being sent via POST or GET. For example, if the script is located at www.example.com/xw110/logger.php, the path would be xw110/logger.php With POST or GET requests, the information is sent using key-value pairs.

  • Page 28 24-hour time format. The XW-110-Plus does not have an event scheduler. If battery’s are installed, time in the XW-110-Plus is battery backed and will not be lost if the device loses power. However, it is recommended to use NTP as it will retrieve the time from the NTP server at power-up and periodically thereafter.
