Overview

The NORTEC OnLine Option provides a web-based remote monitoring capability to equipped
GSTC or SETC 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 user-specified 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.

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
TB3 connection jack on the humidifier logic board, see Figure 3.

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 third­party 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.

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.
