1.6.1 Open the Top Cover
The IOT400 series is design for universal data logging use. There are various interfaces for connecting to your
field devices, and enclosed with an IP65 grade enclosure. All the connection cables to the field devices must be
wired properly through the M16 connectors.
Therefore, prior to connecting and configuring the IOT400, you have to open the top cover to get access to the
control board.
Unscrew the four screws and remove the top cover to the side carefully.

You can see there are lots of hardware connectors available for you to configure. There are two spring-type
Terminal Blocks, Battery Stand, Power Socket and Switch, etc...

WARNING :
1. It is strictly forbidden to have the battery positive and negative short circuit,
charging, discharging, heating over 100 ℃, remove, anatomy, or may cause
explosion, combustion, internal acid leakage.
2. The Li-SOCL2 battery is an one-time battery. DO NOT re-charge, crush,
disassemble, the battery in any situation.
3. Discharged battery is a hazardous waste, and should be recycled or brought
to a hazardous waste disposal facility.
Step 3:
Cut off the extra cable tie, and plug the power cable onto CON3 (Battery Power Socket).

1.6.3Connecting to External Devices
There are lots of available I/O interfaces for connecting the IOT400-DL LoRa node with external devices.
As indicated in the I/O pinout sheet, you can easily find out the pin location and connect to your devices with
appropriate conductive cables. However, there are only two dual-hole M16 water/dust-proof connectors for
you to route the conductive cables out of the enclosure. That is, up to four cables can be routed to connect
external devices.

LoRa Node
15
Run External cable to desired Connectors:
Step 1: a) Find a conductive cable with 15mm tinned terminals; b) Remove the external part of the M16
connector; c) Run the cable through the external parts as indicated below.
Step 2: a) Place the tinned terminal over the connector; b) Use a flathead screwdriver and push down the
clip; c) Insert the tinned terminal to very bottom; d) Release and verify the terminal is well locked.

LoRa Node
16
Screw back the External Parts of M16 Connector:
When you complete all the required hardware and software installation, and make sure it can work as what
you planned. You are ready to lock the cables and external parts of the M16 connectors.
Note:
1. Up to two cables can be run through the M16 connector. And to keep the IP65 water/dust-proof
performance, all the cable gland parts and also the stopper are required to be installed properly.
2. However, if you intend to run more than two cables through the M16 connector, or IP65 is not so critical for
the installation, you can decide not to put the cable glands, and skip step 1b) ~1d) for more IO flexibility.
Step 1: a) Just keep required length of cable inside the enclosure; b) Insert the first cable gland part; c)
Insert the second cable gland part; d) Insert the stopper if there is spare wire hole.
Verify all the insert parts are in positions.
Step 2: Place the last insert part of the M16 connector in position and fasten it clockwise direction.
You have to hold the wire to prevent it twisted while fastening the M16 external part.

Connect to devices via AIs (Analog Input) :
The IOT400 provides 3 AI ports for connecting to those analog sensor/meters. To connect the external devices,
you have to identify the type of your device and properly connect and configure the IOT400 so that it can get
the correct readings from the connected devices.
The AI port supports either 0-10V voltage mode, or 4-20mA current mode analog signal. Since the IOT400 can
not detect what kind of device is connected to, not only hardware configuration (CON4, CON5) is required, but
also software configuration is mandatory.
CON4 is dedicated for AI configuration. There are 3 sets of jumper headers, one for each AI port (AI1, AI2, AI3).
Without Jumper : 0-10V Voltage mode - (factory default)
With Jumper : 4-20mA Current mode - (You have to put the Jumper manually)

The IOT400 is designed with 12-bit ADCs (Analog-to-Digital Converter), considering hardware scaling and 0.1%
resistance variation effects, the overall precision for the 0-10V is around +/-10mV.
If the signal range of your device will run out off the design spec. of IOT400 (0-10V or 4-20mA), you have to
add a certain scaling circuit to prevent overflow readings and even damage the IOT400.

Connect to devices via DIs / DO (Digital Input / Digital Output) :
The IOT400 provides 2 DI ports and 1 DO port3for connecting to those digital sensor/meter devices. To
connect the device, you have to identify the type of your device and properly connect and configure the
IOT400 so that it can get the correct readings from the connected devices.
The DI port supports either Pulse counter mode, or just a Dry contact. Since the IOT400 can not detect what
kind of device is connected to, not only hardware configuration (CON5) is required, but also software
configuration is mandatory.

Connect to Modbus RTU devices via RS-485 :
The IOT400 provides 1 RS-485 port and can support up to 3 cascaded Modbus RTU devices. Since the IOT400
can not detect what kind of device is connected to, not only hardware configuration (CON2) is required, but
also software configuration is mandatory.

Connect to external magnetic switch via WakeUp port :
Most of the time, the IOT400 data logger operates under sleep mode with ultra low power consumption
design. At that time, no one can wake it up till the schedule time out.
If you still have to wake it up for some unexpected reason, for example, to change software configuration or
upgrade new firmware, there is a manually wake-up mechanism for such kind of maintenance situation.
There is an internal magnetic Reed Switch, located at the lower-left corner of the IOT400. You can just take a
small magnet and touch the lower-left corner of the enclosure, the IOT400 will detect it and get into WakeUp
state.
However, it IOT400 is installed at a hard to reach location or enclosed in a metallic cabinet, there is an
alternative option for you to easily wake up the IOT400. In such case, you can connect an external magnetic
switch or some kind of switch and connect it to the WakeUp pins. Once the input status change
(OPENCLOSE), the IOT400 will detect it and get into WakeUp state accordingly.

Connect to external DC Power Source:
IOT400 is designed with internal Battery Power source. It is suitable for the situation for not frequently data
logging or data uploading applications.
However, there is an alternative external DC Power Source for those applications required instantly or
frequently data uploading. Instead of battery power source, you can decide to apply external DC power source
to the IOT400 directly if there is available DC power source at the installation site.

Besides, change the Power Source Jumper to the right side (EXT) at J6, as illustrated below.
Note: The IOT400 won’t get into sleep mode (ultra-low power consumption) when it is powered via external
DC power source.
