Overview
The Nortec OnLine Option provides a web-based remote monitoring capability to equipped GSTC
(sold after March 2009) or SETC (sold after March 2010) series humidifiers. The Nortec OnLine option operates in conjunction with a centralized server based at Nortec 's facilities. This server allows the user to monitor and control various aspects of the humidifier operation. If a fault or service warning is detected the Nortec server will send an email response to three userspecified personnel. Nortec OnLine also provides Nortec with the ability to diagnose the humidifier's performance remotely, ensuring quick response to customer inquiries.
Nortec OnLine provides the advantages of immediate notification and quick diagnosis of humidifier fault conditions, should they arise. Nortec OnLine also provides a user-friendly BMSlike interface, even when a dedicated Building Management System is not available or unfeasible. All that is required for Nortec OnLine’s operation is either an internet connection, an external phone line or a wireless network connection.
Offerings
Nortec OnLine supports three types of connections to the internet: Ethernet, Dialup modem, and
GPRS modem. Both static IP and DHCP addressing is available for ethernet connections. Simply specify at the time of order, which type of connection type would be preferable and any details that may apply (refer to the configuration form at the back of the manual). Once in the field, a user can differentiate between the different connection types by inspecting a tag present on the
OnLine module. This identifier tag will provide details such as connection type and part number information.
For sites where LAN/internet connections are available, the OnLine module may be plugged into the network through an ethernet port present on the control board. NORTEC OnLine is capable of operating with either a Static IP address or a Dynamic IP address. Wide area network (WAN) port 5222 must be opened to TCP traffic for the units to communicate with the NORTEC OnLine
Service.
The Nortec OnLine module also comes equipped with a serial port which allows a dial-up modem or a wireless GPRS modem to be connected. All the necessary programming for the connection details will be pre-programmed at the factory.
Humidifier Wiring
It is possible to network up to a maximum of 8 units to a single Nortec OnLine module. This
OnLine module is located internally to the GSTC or SETC unit. When multiple humidifiers are present, only a single module is required and will be installed inside a 'lead' unit, which can be specified by the user. Since each unit is separately addressed, it is possible to monitor and control each unit independently.
Installation | 1
Figure 1: Networking Layout
2 | Installation
Figure 2: Networking for 2009 Models and Newer
The necessary internal wiring for the gateway is already present except for the network connection that can be made internally to the unit. To network multiple units to a single
Gateway, the units may be daisy-chained to each other using the network link terminals at the
OnLine terminal strip, see Figure 2 and 3.
B+
Figure 3: Connecting Multiple Humidifiers to a Lead Humidifier
Table 1 refers to the recommended wire types and maximum recommended lengths from the
Nortec OnLine module in the lead unit. Since communication between the humidifiers and
Nortec OnLine will always occur via a EIA-485 signal type, Nortec recommends using 18-24
AWG shielded (120 Ω impedance), twisted pair wire between the lead humidifier and each of the secondary humidifiers. Cable runs between the Nortec OnLine module and the furthest
“slave” humidifier should not exceed 2,600 feet. Signal boosters or repeaters may be necessary for longer wire runs. The shield wire(s) should be connected at one end only.
The Nortec OnLine module has been designed and tested to operate with a variety of third-party manufacturers equipment that promote wireless connectivity. Should a user desire to connect the OnLine module to the internet via a wireless connection such as 802.11b or g class network, Nortec can provide recommendations on which equipment to use.
Installation | 3
Ethernet Connections
To connect Nortec OnLine to the internet via a local area network, insert the ethernet cable into the port on the Nortec OnLine module inside the lead humidifier. The serial port is not used in this configuration. The option for Static IP or DHCP addressing is specified at time of order, the units should be visible on the network after being connected. In order to connuicate with the
Nortec OnLine service Lan Port 5222 must be opened (”forwarded or triggered”) for TCP traffic.
GPRS or Dial-up Connections
The Nortec OnLine module is also able to connect with the Nortec Server via a dial-up connection to a local Internet Service Provider or even through a GPRS connection. Should such a connection be desirable Nortec can recommend a variety of third party manufacturers equipment that the Nortec OnLine module has been proven to work well with.
If a dial-up or GPRS connection is desired it will be necessary to contact Nortec at the time of order to provide information on the required settings.
These modems are connected to the serial port on the OnLine module. The ethernet port is not used in this case.

User Webpage Interface
The Nortec OnLine web page can be accessed via the internet address www.Norteconline.com.
After initially logging into the Nortec OnLine server the user will be presented with a list of humidifiers currently registered with the Server program. Each serial number and an address descriptor.
By clicking on the humidifier name, the user will then be brought to a status screen with an image of the selected humidifier. Refer to Figure 5.
The status screen, refer to Figure 6 provides the user with a quick reference to the unit’s operation.
Several key status values can be gathered at a glance. Refer to Table 2 for a description of the variables displayed on the status screen.

Problem
The NORTEC server cannot read/write any information to any of the networked humidifiers.
The NORTEC server network can see some of the networked humidifiers but not others.
Table 5: Troubleshooting Communication Problems
Solution
Verify that the network connection is made and is connected properly.
Verify that firewall port 5222 is open to TCP traffic.
Verify that the correct network settings are being used. The OnLine module may need to be restarted to load the new settings.
Check the ethernet link (if ethernet enabled) or serial link (if modem enabled) communication LED's to determine if there is any network traffic being sent or received by the OnLine module from the NORTEC server. Verify proper connections to networked humidifiers.
Turn the OnLine module off for several seconds then switch it back on to reload the control program. Allow for some time for the network variables to be polled.
Ensure proper connections to the humidifiers.
Disconnect all of the humidifiers from the NORTEC OnLine module except for the unit that is not responding to the network. Disconnect power to the OnLine module, wait a moment, then reconnect power. Check Serial Link LED transmit/receive lights to see if the module can talk to the humidifier.
Verify that each unit has a unique modbus address (no conflicts).
