CPL03-KS LTE CAT-1 Pulse/Contact Sensor

1. Introduction

1.1 What is CPL03-KS LTE CAT-1 Pulse/Contact Sensor

The Dragino CPL03-KS is a LTE CAT-1 Contact Sensor for Internet of Things solution. It detects dry contact status, open time, open counts, and then upload to IoT server via LTE CAT-1 network.

The CPL03-KS will send periodically data every day as well as for each dry contact action. It also counts the contact open times and calculate last open duration. User can also disable the uplink for each open/ close event, instead, device can count each open event and uplink periodically.

CPL03-KS supports open alarm feature, user can set open alarm for instant notice.

CPL03-KS is designed for outdoor use. It has a weatherproof enclosure and industrial level battery to work in low to high temperatures.

CPL03-KS supports different uplink methods including MQTT, MQTTs, UDP or TCP for different application requirement, and support uplinks to various IoT Servers.

CPL03-KS supports BLE configure and OTA update which make user easy to use.

CPL03-KS is powered by 3000mAh Li-ion battery, It is designed for long term use up to several years. (Real-world battery life depends on the use environment, update period and uplink method. Please check related Power Analyze report).

CPL03-KS has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.

*make sure you have LTE CAT-1 coverage locally.

1.5 Sleep mode and working mode

**Deep Sleep Mode: **Sensor doesn't have any CAT-1 activate. This mode is used for storage and shipping to save battery life.

Working Mode: In this mode, Sensor will work as CAT-1 Sensor to Join CAT-1 network and send out sensor data to server. Between each sampling/tx/rx periodically, sensor will be in IDLE mode), in IDLE mode, sensor has the same power consumption as Deep Sleep mode.

1.6 Button & LEDs

Behavior on ACT	Function	Action
1~3s	Send an uplink	If sensor has already attached to NB-IoT/CAT-M1 network, sensor will send an uplink packet, blue led will blink once. Meanwhile, BLE module will be active and user can connect via BLE to configure device.
>3s	Active Device	Green led will fast blink 5 times, device will enter OTA mode for 3 seconds. And then start to attach NB-IoT/CAT-M1 network. Green led will solidly turn on for 5 seconds after joined in network. Once sensor is active, BLE module will be active and user can connect via BLE to configure device, no matter if device attach NB-IoT/CAT-M1 network or not.
x5	Deactivate Device	Red led will solid on for 5 seconds. Means device is in Deep Sleep Mode.

Note: When the device is executing a program, the buttons may become invalid. It is best to press the buttons after the device has completed the program execution.

1.7 BLE connection

CPL03-KS support BLE remote configure and firmware update.

BLE can be used to configure the parameter of sensor or see the console output from sensor. BLE will be only activate on below case:

Press button to send an uplink
Press button to active device.

2. Use CPL03-KS to communicate with IoT Server

2.1 Send data to IoT server via CAT-1 network

The CPL03-KS is equipped with a CAT-1 module, the pre-loaded firmware in CPL03-KS will get environment data from sensors and send the value to local CAT-1 network via the CAT-1 module. The CAT-1 network will forward this value to IoT server via the protocol defined by CPL03-KS.

Below shows the network structure:

There are two version: -GE and -1T version of CPL03-KS.

GE Version: This version doesn't include SIM card or point to any IoT server. User needs to use AT Commands to configure below two steps to set CPL03-KS send data to IoT server.

Install NB-IoT SIM card and configure APN. See instruction of Attach Network.

Set up sensor to point to IoT Server. See instruction of Configure to Connect Different Servers.

Default working modeAT Command: AT+MOD=1Downlink Command: 0x02 01

The wiring of the Real-Time Open/Close Status mode is as follows：

3.4.1.1 Set Alarm Base on Timeout

It only takes effect when AT+MOD=1.

CPL03-KS can monitor the timeout for a status change, this feature can be used to monitor some events such as door opening too long etc. Related Parameters are:

1. Keep Status: Status to be monitor

Keep Status = 1: Monitor Close to Open event

Keep Status = 0: Monitor Open to Close event

2. Keep Time: Timeout to send an Alarm

Range 0 ~ 65535(0xFFFF) seconds.

If** keep time = 0**, Disable Alarm Base on Timeout feature.

If keep time > 0, device will monitor the keep status event and send an alarm when status doesn’t change after timeout.

AT Command: AT+TTRIG

AT+TTRIG=1,30 --> When the Keep Status change from connect to disconnect, and device remains in disconnect status for more than 30 seconds. CPL03-KS will send an uplink packet, the Alarm bit (the second bit of 1^st byte of payload) on this uplink packet is set to 1.

**AT+TTRIG=0,0 ** --> Default Value, disable timeout Alarm.

**Downlink Command: 0x0F **

Format: Command Code (0x0F) followed by 8 bytes, each parameter after 0F takes 4 bytes.

Example: Downlink payload: **0x0F 00 00 00 01 00 00 00 1E ** // AT+TTRIG=1,30 30(D)=0x1E(H)

3.4.1.2 TTRIG timeout status alarm

Feature: Set TTRIG of Alarm interval. (unit: minute)

It only takes effect when AT+MOD=1.
It needs to be used with AT+TTRIG . When TTRIG times out and causes an alarm, and the status does not change subsequently, an alarm packet will be sent at the alarm interval.

AT Command: AT+TTRALARM

Example:

AT+TTRALARM=0 // disable continuous alarm
AT+TTRALARM=60 // Set the alarm interval to 60 minutes (unit: minutes)

Downlink Command: 0x0A

Example:

Downlink payload: 0x0A 00 // AT+TTRALARM=0
Downlink payload: 0x0A 3C // AT+TTRALARM=60, 60(D)=0x3C(H)

3.4.1.3 Clear current door open count

Feature: Manually Clear current door open count

**AT Command: AT+CLRC ** // Clear current open count and the duration of the last open

Downlink Command: 0xA1 00 // AT+CLRC

3.4.1.4 Enable / Disable Alarm

Feature: Enable/Disable Alarm for open/close event. Default value 0.

AT Command: AT+DISALARM


Command Example	Function	Response
AT+DISALARM=1	End node will only send packets in TDC time.	OK
AT+DISALARM=0	End node will send packets in TDC time or status change for door sensor	OK

Downlink Command: 0x0B

Example: Downlink payload: **0x0B 00 **// AT+DISALARM=0

3.4.2 pulse mode

To use this working mode, you need to set AT+MOD=2.AT Command: AT+MOD=2Downlink Command: 0x02 02

The wiring of the three pulse counting mode are as follows：

For AT+MOD=2:

3.4.2.1 Port1,Port2,Port3 count mode

**Port1: **Get or Set the trigger interrupt mode(PA8)

** AT Command: AT+TTRMOD1 0: Signal falling edge(Default), 1: Signal raising edge**

         Ex1: AT+TTRMOD1=0   // Count and trigger from close to open (falling edge), default.

         Ex2: AT+TTRMOD1=1   // Count and trigger from open to close (rising edge).

** Downlink Command: 0x0C **

         Example: 0x0C00     // AT+TTRMOD1=0

**Port2: **Get or Set the trigger interrupt mode(PA4)

** AT Command: AT+TTRMOD2 0: Signal falling edge(Default), 1: Signal raising edge**

         Ex1: AT+TTRMOD2=0   // Count and trigger from close to open (falling edge), default.

         Ex2: AT+TTRMOD2=1   // Count and trigger from open to close (rising edge).

** Downlink Command: 0x0D **

         Example: 0x0D01     // AT+TTRMOD2=1

Port3: Get or Set the trigger interrupt mode(PB15)

         Ex1: AT+TTRMOD3=0   // Count and trigger from close to open (falling edge), default.

         Ex2: AT+TTRMOD3=1   // Count and trigger from open to close (rising edge).

** Downlink Command: 0x0E **

         Example: 0x0E00     // AT+TTRMOD3=0

3.4.2.2 Set the calculate flag

Feature: Set the calculate flag**(Range is 0 to 7), It only takes effect when AT+MOD=2. AT Command:AT+CALCFLAG=aa ( Default : 0 )**

         Example: AT+CALCFLAG=2

** Downlink Command: 0xA3**

         Example: 0xA3 02     // AT+CALCFLAG=2

3.4.2.3 Set Count value

Feature: Manually set the count number

In Real-Time Open/Close Status mode work mode, the Total_pulse set by the "AT+SETCNT=1,xx" command.

In 3 x pulse counting mode work mode, the Port1_Total_pulse(PA8) set by the "AT+SETCNT=1,xx" command.

** AT Command: AT+SETCNT**

        AT+SETCNT=1,aa  

        AT+SETCNT=2,aa  

        AT+SETCNT=3,aa  

There is no corresponding downlink command.

There is a downlink instruction to clear the count: **0x10 00, **when the user downlinks 0x10 00, the count of Port1, Port2 and Port3 clears to 0.

3.5 Count Mod

Feature: Manually set the count mode.

3.11 Clock logging

Sometimes when we deploy lots of end nodes in field. We want all sensors sample data at the same time, and upload these data together for analyze. In such case, we can use clock loging feature.

We can use this command to set the start time of data recording and the time interval to meet the requirements of the specific collection time of data.

AT command: AT+CLOCKLOG=a,b,c,da: 0: Disable Clock logging. ** 1: **Enable Clock Logging

**b: **Specify First sampling start second: range **(0 ~ 3599, 65535) ** // **Note: **If parameter b is set to 65535, the log period starts after the node accesses the network and sends packets.

**c: **Specify the sampling interval: range **(0 ~ 255 minutes)d: **How many entries should be uplink on every TDC (max 32)Note: To disable clock recording, set the following parameters: AT+CLOCKLOG=1,65535,0,0Example:AT+CLOCKLOG=1,65535,1,5

After the node sends the first packet, data is recorded to the memory at intervals of 1 minute. For each TDC uplink, the uplink load will include: battery information + the last 5 memory records (payload + timestamp).

Note: Users need to synchronize the server time before configuring this command. If the server time is not synchronized before this command is configured, the command takes effect only after the node is reset.Downlink command: 0x08

Format: Command Code (0x08) followed by 5 bytes.

Example 1: Downlink Payload:** 08 01 FFFF 0F 08** // Set SHT record time: AT+CLOCKLOG=1,65535,15,8
Example 2: Downlink Payload:** 08 01 04B0 0F 08** // Set SHT record time: AT+CLOCKLOG=1,1200,15,8

Note: When entering the downlink payload, there must be no Spaces between bytes.

Unix TimeStamp

6. FAQ

6.1 How can I access the EG800-NGFF AT Commands?

User can access to EG800-NGFF directly and send AT Commands.

See BG95-NGFF AT Command set

6.2 How to Connect Dry contacts or Wet Contacts

CPL03-KS can only be connected to dry contacts by default, and the wiring method is to connect the two ports of dry contacts to the VDD pin and pulse input pin of CPL03-KS respectively.

If you want to connect a wet contact, you need to change the original wiring method. The wiring method is that the GND of the wet contact is connected to the GND of CPL03-KS, and the pulse output is connected to the pulse pin, but the pulse output voltage of the wet contact must be less than 3.6V.

6.3 What is the maximum total number of pulses for CPL03? What happens after the maximum total number of pulses is reached?

The maximum total number of pulses for CPL03 is three bytes FF FF FF (16,777,215).

The count is reset when the maximum total number of pulses is reached.

6.4 General Manual for -KS , -KN models

Users can follow the instructions in this link to see how to configure to connect to different servers.

6.5 Why is there no LED response when I press the button on the solar panel model?

If the LED does not light up when you press the button, it may be because the battery has entered protection mode.

Solution: To reactivate the battery, simply expose the solar panel to direct sunlight.
For more details, please refer to: Battery Protection State (Apply to Solar Panel + Li-ion battery)

6.6 Why does the CPL03-KS have 6 wires externally but only 4 inside the terminal block?

The CPL03-KS is designed to support three dry contact inputs. Each dry contact requires two connections: one to a pulse input pin and one to VDD.

At the field sensor side, all six wires are available:

Pulse Input 1: White wire → PA8 & Black → VDD
Pulse Input 2: Red wire → PA4 & Yellow → VDD
Pulse Input 3: Green wire → PB15 & Orange → VDD

At the device side, only four wires are terminated:

To simplify field wiring and avoid connecting multiple wires to the same VDD terminal (which can be difficult due to the small screw terminal size), the yellow and orange wires are internally connected (soldered) to the black wire at the device end. This means only one wire (Black) needs to be connected to the VDD, while the other end of the cable still provides six individual wires for easy connection to three dry contacts.

This design improves terminal block connection reliability and simplifies installation.
