speed, Advantech products used, other hardware and software used, etc.) Note
anything abnormal and list any onscreen messages displayed when the prob-
lem occurs.
2. Call your dealer and describe the problem. Please have your manual, product,
and any helpful information readily available.
3. If your product is diagnosed as defective, obtain a return merchandize authori-
zation (RMA) number from your dealer. This allows us to process your return
more quickly.
4. Carefully pack the defective product, a completed Repair and Replacement
Order Card, and proof of the purchase date (such as a photocopy of your sales
receipt) into a shippable container. Products returned without a proof of pur-
chase date are not eligible for warranty service.

1.1 NB-IoT (Cat. NB) and LTE-M (Cat.M)
NB-IoT and LTE Cat. M1 are new wireless technologies included in the 5G evolution
of cellular technology standards defined by the 3rd Generation Partnership Project
(3GPP).
NB-IoT and LTE Cat. M1 feature low power consumption and utilize LTE networks
based on licensed spectrum bands. These technologies are optimized for connectiv-
ity to machines, assets and sensors in order to enable IoT applications such as smart
cities, smart agriculture and remote asset management.
WISE-4671 series is a cellular based IoT wireless sensor node compliant with LTE
Cat. NB1 and Cat. M1 with external for flexible installation. In addition to offering var-
ious I/O types, WISE-4671 series provides a data logger and direct cloud connectivity
so that data can be published to the cloud by messaging protocol such as MQTT,
CoAP, LwM2M with secure socket supported.
WISE-4671 follows MQTT's publish and subscribe messaging model which is ideal
for low bandwidth, high latency, and data limits. Additionally, as an IoT device, WISE-
4671 also supports lightweight protocols such as CoAP, which are suitable for small
devices that are unable to communicate efficiently with limited resources. As MQTT
and CoAP are popular standards in the market, the data format can raise concern
over messaging protocols. Accordingly, WISE-4671 also supports the LwM2M proto-
col which has the management interface built on top of CoAP to enable device man-
agement operations.
There is also the official publication of OMA LwM2M2 Objects and Resources to alle-
viate data inter-compatiblity concerns. LwM2M is a protocol offering flexible and scal-
able device management with improved time to the market; especially for low power
devices with constrained processing and storage capabilities.
1.2 WISE-4671 Feature Highlights
Advantech’s WISE-4671 NB-IoT/LTE-M wireless I/O module can be configured to
support either NB-IoT or LTE-M using the WISE Studio utility via a USB port.
For advanced industrial applications, WISE-4671 can be equipped with optional
GPS, a solar rechargeable battery, and an IP65-rated enclosure to protect from water
and dust ingress.
The WISE-4671 wireless I/O module features an intelligent modular design that sup-
ports various I/O configurations according to usage requirements. This allows users
to easily integrate their desired I/O module (WISE-S614, WISE-S614T etc.) with the
WISE-4671 module.

WISE-4671 module.
There are three ways to power up the WISE module, battery power, solar panel
power and line power. Open the rubber cover on the side of the WISE module and
you will see a battery switch for turning on/off the battery power. Solar power not only
recharges the battery but also powers up the device. Please refer to the application
wiring section for solar panel power and line power pin assignment. Also, there is a
USB port for the device configuration via WISE Studio but please note that the WISE
device cannot be powered via USB.

When the battery is powered up (when the device is in “Line Power” only, or “Line
Power” and “Battery Power” mode) the signal strength indicators will show battery
capacity when pressing the membrane button, and will off after a while for power sav-
ing.
Push the button again to show the signal strength.
If there is no external line power and the battery is powering the device, the device
will go into “battery power only mode.”
Battery powered only Mode
In battery powered only mode, the LED indicators will display the device status after
25 seconds. The signal strength will be shown by the LED indicators when turning on
the battery powered device.
After 25 seconds, the LED will go off for power saving.
Press the membrane button again and the 4 signal strength LED indicators will show
the battery level after 25 seconds.
Press the button again and the LED will go off.
When the LED goes off, pressing the button again will make the 4 LED indicators
display the signal strength again.
Note! It requires at least 10ms to press the membrane button.

2Hardware Installation

WISE-4671 User Manual 10
The wireless sensor nodes for WISE-4671, like those for all WISE-4000 series mod-
ules, are designed as separate units. The procedure for installing these nodes in the
module is explained in the following sections.
2.1 Modular Design
WISE-4671 features a modular design that supports various I/O configurations. The
benefit of a modular design is that the same wireless board can be leveraged by dif-
ferent I/O modules via a board-to-board connector based on the required usage sce-
nario. This allows users to install two I/O modules according to their specific usage
requirements. Moreover, the modules can be affixed to WISE-4671 using the six star
screws provided (as shown in Figure 2.1).
Figure 2.1 I/O Module Installation
Note! The recommended star screw torque is 2.5 ~ 3.0 kgf/cm2.
