9. Usage Scenarios and Connection Diagrams

Some of the usage scenarios of CKL Series Modbus, Serial to Ethernet Gateways are described below. Usages are not limited to that examples and user may create their own usage scenario.

9.1 Communicate Remote Serial Devices over TCP IP Network

CKL Series Modbus, Serial to Ethernet Gateways can connect field serial device to TCP/IP Network to control that devices remotely with a software on a server or with a TCP/IP device. For example, with CKL Series Modbus, Serial to Ethernet Gateways, users can connect field serial devices such as Electricity Energy Meters and create a system to read that devices remotely.

CKL Gateway devices in field configured for Transparent Communication and act as TCP Server to Serial Device Gateway. Field devices are connected over serial line either over RS232 or RS485 and communication data type and baud rate fixed. 
In need of remote reading of Electricity Energy Meters over optical probe, CKL can still be configured for Transparent Communication and act as TCP Server to Serial Device Gateway and a REDZ MBC144 can be connected for Auto Baud Rate Change together with REDZ KMK114 RS485 optical probe.

9.2 TCP/IP Link for Field Serial Devices

CKL Series Modbus, Serial to Ethernet Gateways can connect field serial devices over TCP/IP Network just like they are connected over serial line. For example, with CKL Series Modbus, Serial to Ethernet Gateways, users can connect 2 different field serial devices such as a Controller and a Sensor and create a system to communicate transparently over TCP/IP Network.

CKL Gateway device in Controller side configured for Transparent Communication and act as TCP Client to Serial Device Gateway. Field device is connected over serial line either over RS232 or RS485 and communication data type and baud rate fixed. CKL can connect to Other CKL device on sensor side by manual entering the IP of TCP Server or simply using REDZ special design, plug and play Server-Client Operating Modes.

From this menu user may change parameters or send command to device.

  • User can not change system time. There is no battery inside the device so clock will be lost after a power down and will set to default.

The device restarts itself every 86400 seconds (which means every 24 hours). There are also timeout restart routines in Server mode during listening clients and in Client Mode trying to connect to the server. ( both preset to 10 minutes which means device will restart system if fails to connect a server in Client mode or a client do not connect in preset time in Server mode.)

  • User can change firmware of device. REDZ CKL Series Modbus, Serial to Ethernet Gateways have easy to use firmware capability and system can store 2 firmware at memory. After a firmware change, user can restore back old firmware anytime needed.

After a firmware change old configuration will be used for minor changes. If a major change occurs system will restore to factory default configuration.

  • User can change the login information

  • User can change the debug level of the device. REDZ CKL Series Modbus, Serial to Ethernet Gateways series have micro USB and gives log in 115200 - 8N1 format.
    Any terminal program can be used to listen the LOG over micro USB port of the device which is recognized as Virtual COM port in PC.

  • User can restore to factory settings and force device to reboot. Factory settings restored for Client if the device in Client mode and factory settings are restored for Server if the device in Server mode.



Firmware upgrade is possible only with files that REDZ supplied. Once the file selected, CKLshows selected file:

Then “Upload Firmware” button must be clicked. Then user must wait until page shows the result.

This may take few seconds only. Please wait .

Then system will show the firmware date and version and user can reboot that firmware.

Typical log for the system is shown below.
