Page 3: Section 1: Introduction
The XW-112 is a self-contained device that requires no additional servers or ControlByWeb devices. The XW-112 can provide real-time status to users through web browsers or the CBW Mobile app. In addition, it offers the ability to monitor the sensor status and send out email alerts (which can be converted to text message alerts) whenever an alarm condition occurs.
Page 4: Part Numbers And Accessories
The XW-112 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 5: Section 2: Installation And Setup
The XW-112 can be programmed to activate a relay at a remote location and/or send an email warning when a water leak is detected. After installation, test the sensor with a damp sponge or wet towel and inspect annually.
Page 6: Power / Batteries
The GRI-2605 water sensor has an internal relay which provides a supervised closed-loop alarm circuit. The circuit requires power from a 5-volt DC wall transformer and will not operate from batteries alone. Installing batteries however, allows the XW-112 to sent a “power fail” email notification if the AC power fails. The liquid detection sensor is inactive during a power failure.
Page 7 After making the sensor connections and providing power, you must provision the XW-112 to use it on your wireless network. The goal is to configure the XW-112 such that it can recognize and attach to your Wi-Fi access point. There are two methods for doing this: 1.
Page 8 Although using this method to connect the XW-112 to the network is simple, you will not be able to access the XW-112 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. For this...
Page 9: Application Example
IP address. Your Wi-Fi network must have adequate coverage to connect to the XW- 112 as well. Connect the GRI-2605 sensor to the XW-112 and mount it near the floor where the water is to be detected. To provide for an AC power-fail email alarm, install two AA batteries. (Note: Your Wi-Fi access point must be powered by an uninterruptible power supply (UPS) in order to send a power-failure notification.)

IP address that was assigned to the device. If the XW-112 has been added to a network using WPS, it will use DHCP and you will need to use the IP address assigned to it by the DHCP server or router.
Page 11 This is the current product revision of the internal software Serial Number This is the serial number of the XW-112. The serial number is also the MAC address of the unit. Power Supply This field shows if the XW-112 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 12 Use DHCP This option allows DHCP to be enabled or disabled. If this option is set to Yes, the XW-112 will wait for an IP address from a DHCP server each time it is powered. The default setting is No (this is Page 12 Xytronix Research &...
Page 13 The XW-112 is a server and manual IP address assignment is usually recommended. IP Address Enter the IP address for the XW-112 in this field. The IP address is specific to the network where the XW-112 will be installed and is obtained from the network administrator. The default setting for this field is 192.168.1.2...
Page 14 This option enables or disables Remote Services. If Yes is selected, Remote Services will be enabled as soon as the Submit button is pressed and XW-112 will immediately attempt to make a connection with a custom remote server (power cycle not required). Once a connection is established, the connection will remain until it is disconnected by the remote server.
Page 15 Client Certificate. Care should be taken with where this client key is stored as it is meant only to be known to the XW-112. To upload a custom client key to the XW-112, click the Browse button, find the PEM formatted file, and select Submit.
Page 16 XW-112). This has two main benefits. First, the web server does not need to know the IP address of XW-112. This means that XW-112 can get its IP address dynamically from a DHCP server, simplifying the installation. Second, since the connection from XW-112 is outgoing, rather than incoming, the local router on the network where XW-112 resides doesn't need to be configured to forward sockets.
Page 17 50%. Weekly Status Email When checked, the XW-112 will send an email at least once a week with water sensor status and battery information. This provides ongoing assurance the unit is functioning properly. The weekly emails are sent 7-days from the last email that was successfully sent, including alarm or low battery emails.
Page 18 Email on AC Power Fail When enabled, the XW-112 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 the internet is still available.
Page 19 Note: When the XW-112 is in Access Point mode, your smart-phone or computer connects directly to it and the XW-112 is not connected to the Internet. In this mode, no email messages can be sent and the Test Email button is disabled.

Remote Services The XW-112 can be configured to send messages to other ControlByWeb™ products or servers that are located at a remote location and running the remote services' server software. If the check box is set, the XW-112 will transmit a status message whenever the water alarm changes state.
Page 24: Section 4: Control Page
Once the XW-112 is set up, users can access the Control Page by either clicking the Control Page tab from within the setup pages, or by using a web browser and typing the IP address of the XW-112 into the web browser address bar.
