Green: WiFi module is connect to your router successfully. White: network run in “TCP Client” mode. Yellow: network run in “TCP Server” mode. Blue: network run in “UDP” mode. (Not used now) **what’s UDP , TCP Server, TCP Client means:** When set to “TCP Server”, controller own is a server work in local network ,you can use “KBOX” phone app without internet and our cloud server to control relay in local network.just your mobile phone or PC and controller connect with same router. When set to “TCP Client” and set the server IP and port, controller will auto connect to your own server (not KinCony’s cloud server), you can write program for server and make your own phone app to use, this for developer to use. **what’s buttons function:** Button1 “WiFi Reset” : Reset WiFi module, then controller will be work as “AP” mode, you will see the wifi signal “LPT230” for use.Now you can config the ssid and password for your router. Button2 “Ethernet Mode” : change ethernet work mode for UDP->TCP Server->TCP Client. Button3 “WiFi Mode” : change WiFi work mode for UDP->TCP Server->TCP Client. **How to use buttons:Button1 “WiFi Reset” :** Hold on the button for 5 seconds,then restart power of controller. **Button2 “Ethernet Mode” :** Hold on the button until LED color changed. There are 5 status: a.) Hold on button, when the [yellow LED] is ON, release it, then work mode in “TCP server” mode; b.) Hold on button, when the [white LED] is ON, release it, then work mode in “TCP Client” mode; c.) Hold on button, when the [blue LED] is ON, release it, then work mode in “UDP” mode; (Not use now) d.) Hold on button, when the [yellow and white LED] all is ON, release it, then work mode in “UDP” and IP by DHCP mode; e.) Hold on button, when the [yellow and white and blue LED] all is ON, release it, then work mode in “TCP Server” and IP (192.168.1.200) by static mode; Note: after changed mode, the controller will restart automatically. The controller default work mode is DHCP and TCP Server mode. **Button3 “WiFi Mode” :** Hold on the button until LED color changed. There are 3 status: a.) Hold on button, when the [yellow LED] is ON, release it, then work mode in “TCP server” mode; b.) Hold on button, when the [white LED] is ON, release it, then work mode in “TCP Client” mode; c.) Hold on button, when the [blue LED] is ON, release it, then work mode in “UDP” mode; (Not used now) Note: after changed mode, the controller will restart automatically. The controller default work mode is DHCP and TCP Server mode. **2.Network SettingA. use Ethernet port to config IP and different work mode and Wifi network setting** connect network cable with router, you can see the ethernet IP address or use other [network IP scan software](https://www.kincony.com/download/Advanced-IP-Scanner.zip) to find the controller’s ethernet IP. When you scan IP, you will find named “KC868-ETH-xxxxx” or “Wiznet” device, that’s our controller. Open browser, enter the IP, then you can open the config website. You can change work mode, different work mode function as same as WiFi’s. Login user name and password default is : admin admin ![ip scan](https://www.kincony.com/images/kc868-h32b/scan-ip-device.png) ![network setting](https://www.kincony.com/images/kc868-colb/guide/network-setting-1.jpg) ![wifi setting](https://www.kincony.com/images/kc868-colb/guide/network-setting-2.jpg) **SSID and password:** These are your router’s. **Work Mode:** 1- TCP Server: Work in local network without internet, you can use PC application. 2- TCP Client: This mode for programmer or developer, controller can connect to your own cloud server by TCP socket connection. **2.How to use software** Firstly, use IP and Port connect to KC868-COLB logical controller. ![network](https://www.kincony.com/images/user-guide/kc868-col/network-setting-eng.png) Input IP and Port Connect/disconnect— PC Connect/disconnect with KC868-COL. All works need connect successfully firstly. ![plc software](https://www.kincony.com/images/user-guide/kc868-col/monitor-eng.png) 2.Optional 2.1 Monitor ![temperature sensor](https://www.kincony.com/images/user-guide/kc868-col/temperature-c.png) Temperature Sensor Read 5 channels DS18B20 temperature sensors’ value, range(-55℃–125℃), ℃ is default unit, can change to ℉ to display. [Refresh]:Read all temperature sensors for one time. [Refresh Always]— Read all temperature sensors at regular time that you set. (100ms—3000ms) DI Status 1#—16#— 16 channel Digital Input Channel [Refresh]:Read all DI for one time. [Refresh Always]— Read all DI at regular time that you set. (100ms—3000ms) Analogy Sensor 1#—16#— 16 channel Analog Input Channel [Refresh]:Read all AI for one time. [Refresh Always]— Read all AI at regular time that you set. (100ms—3000ms) Analogy Sensor Properity ![range setting](https://www.kincony.com/images/user-guide/kc868-col/range-setting-eng.png) Double Click analog sensor dashboard can show [Analogy Sensor Properity] (Range) Minimize Value: Actual physical range minimum value of input sensor (Range) Maximize Value: Actual physical range maximum value of input sensor Unit：Actual physical unit, Such as M/Pa/KG/V etc coefficient：Defualt is 100，The formula of coefficient value is：（Maximize Value-Minimize Value）/5 [ For example，Water level sensor range is 0-10Meter, coefficient is (10-0) / 5=4 ] Shape (0-360)：dashboard shape angle，default is 360 circular dashboard. For example , you can use 270,180,140 for different shaped dashboard. ![sensor](https://www.kincony.com/images/user-guide/kc868-col/dashboard-140-eng.png)![sensor](https://www.kincony.com/images/user-guide/kc868-col/dashboard-180-eng.png)![monitor](https://www.kincony.com/images/user-guide/kc868-col/dashboard-270-eng.png) 2.2 Customize ![custom command](https://www.kincony.com/images/user-guide/kc868-col/transparent-transmission-eng.png) Communication Transparent Transport RS485– Edit command, send it by KC868-COL’s RS485 port, Communication baud rate is 9600bps. RS232– Edit command, send it by KC868-COL’s RS232 port, Communication baud rate is 115200bps.

Mainly for debug and testing use. User define Command Create MAX 32 user define command line for ”IFTTT” use. “User define command” output to KC868-COL’s RS232 port. Hex— Check this option, will convert string command to HEX format, otherwise send command by AnsiString format. Chose “User define command” ID, then input command in edit area. Clear Dis.– Clear edit area. Read Cur.– Read selected ID of “User define command” from KC868-COL Write Cur.– Write selected ID of “User define command” to KC868-COL Delete Cur.– Delete selected ID of “User define command” in KC868-COL Delete All.– Delete all ID of “User define command” in KC868-COL 2.3 Controller ![relay control](https://www.kincony.com/images/user-guide/kc868-col/relay-control-eng.png) Relay Input Status—01#–08# input port of KC868-Hx controller [ReadOnce]:Read input status of KC868-Hx controller for one time. Relay Control— [01#–32#]: 32 channel relay that connect with KC868-COL for manual control. Press ico, relay ON,color will be Green. Press ico, relay OFF, color will be Yellow. [Read State]— Read controller’s relay status [Multi.Out]— Right mouse button click relay ico, ico will dispaly “S” for select the relay, you can select for more relay channels, then press “Multi.Out” button for turn ON relays once time. ![relay controller](https://www.kincony.com/images/user-guide/kc868-col/relay-select-eng.png) [All Open]—-Turn ON all relays [All Close]—-Turn OFF all relays Note：KC868-COL can connect with any controller of KC868-H32L,KC868-H16,KC868-H8,KC868-H4,KC868-H2 for different relay channel selected for automatic control system. 2.4 parameter ![setting](https://www.kincony.com/images/user-guide/kc868-col/hardware-setting-eng.png) Set Main board Param Temperature Variation: Report send message to PC when the temperature value change difference at variation value. For example: when “Temperature Variation” is set to 1℃, if the second channel temperature rises from 25℃ to 26℃ or the temperature drops from 26℃ to 25℃, KC868-COL will automatically send the second channel temperature data to PC, and the monitor dashboard will refresh the new data value of the second channel temperature sensor (Note: need Enable the “Auto Report” function in the software homepage). Analogy Variation: Report send message to PC when the analogy value change difference at variation value. For example: when “Analogy Variation” is set to 0.1V, if the second channel rises from 2.5V to 2.6V or drops from 2.6V to 2.5V, KC868-COL will automatically send the second channel data to PC, and the monitor dashboard will refresh the new data value of the second channel sensor (Note: need Enable the “Auto Report” function in the software homepage). Auto Send—-KC868-COL auto report to PC at a regular time for temperature and analogy sensor. (0–254second) [Setup]— Write config to KC868-COL Data and Time Setting— It’s display the KC868-COL’s system data and time.
