Charon I – Web51 Home Control FWThe Charon I module with this firmware controls the RS-232 line, 8x inputs and 8x outputs, LCD display and up to 4 one-wire thermometers via Ethernet network, using Telnet or Web browser application. We should recommend you to use the Charon I Development Kit for testing and using the firmware. You can use the Charon I&II DB, which contains shifted peripherals and it's standard distributed with the Charon 2 module.This firmware is not the default firmware, so you need to upload this firmware to the module. The basic network parameters are set via RS-232 line later using the easy standard terminal application.The application is available with the source codes in the development version of Web51 system as an example. Basic Description
The Controlled and supported peripheralsThe Web51 Home Control uses the RS-232 line and 8 bits I/O port P1. You can set up two P port modes, the first is the direct port mode and the second one is a shift register usage mode. The recommended shift registers scheme is available on our web page (see Charon I&II Development Board). 8 bits port P1 – Direct accessIf you need only several I/O pins, use the Direct port communication mode. Than you can remotely control:
Using the external shift registersIf you are using the recommended P1 port extension, you will get a very powerful tool with:
Doporučený hardware
The module should be used with any other basic board, which supports at least the power supply and the right Ethernet connection. The SNMP module’s firmware instalation
The Charon Module has already the default firmware Convertor Ethernet
/ RS-232 uploaded, so the first step is to change the firmware containing
SNMP application. We will use the original Atmel's Flip program
for upload the T89C51RD2 processor.

Set
the Serial Terminal application’s parameters to 9600 Bd 8N1, no handshake.
Check, if the SETUP jumper is connected and the PSEN jumper is disconnected.
Than reset the module.| ATTENTION |
|---|
| After each firmware upload, you must make RESET all the module's SETUP parameters to default. The internal EEPROM must be initialized by this way. Otherwise, the module does not work properly. |
The Commands description
D: Reset to defaults |
This command reloads the default EEPROM setup settings. After that the defaults are loaded, set the IP address Mask and Gateway of the module.
S: Telnet/SMTP Server IP |
It is an IP address of the other communication side:
- If you would like to send e-mails, set the SNTP server’s IP address.
- If you would like to use the module as a Client, set the server’s IP address.
The IP address must be different from the IP of the Gateway.
B: Speed 9600,N,8,1 |
Serial port speed: 1: 38400 Bd 2: 19200 Bd 3: 9600 Bd 4: 4800 Bd 5: 2400 Bd 6: 1200 Bd 7: 600 Bd |

Running and Testing the Web51 Home Control Application
Disconnect the SETUP jumper and reset the application. No page will be displayed in the terminal window. The module is in the normal, running mode.
Go to the START-> Run Application and write the command: PING x.x.x.x –t and press the Enter. The number x.x.x.x is the module’s IP address. After that you have pessed the Enter key, the computer tries to find the response of the module. If the module is set and connected well, there will be a response displayed in the window.
Now it’s time to try the WWW connection. Run the internet Explorer or any other internet browser and write the modules www address: http://x.x.x.x for example in my case http://192.168.6.15.
The module generates the HTML page (see the picture on first page), where you can see the states of the peripheries. If you have accessed the page first time or no thermometers are connected, there are no temperatures displayed. Connect the thermometers and run SETUP. You can try to change the outputs values. If there was set a password in the SETUP mode, you have to write it to the text box. Otherwise no changes will be done!
If no LED is lighting, chack the LED jumper position.
The module is now tested. You can start to work with other module’s options now.
Note: After each manipulation with SETUP jumper, you must reset the module!

Connect the thermal sensor as shown on the picture. GND, +5V, and the
DQ pin to the P1.0 pin. Set the port to the SHIFT mode in the SETUP. You
can add up to 4 sensors using the „A“ and „E“ commands. The thermometers
can work in the same time, but if you are connecting a new thermometer,
there mus be only one connected to the module. The module reads the sensors
serial number.

Select Z: System configuration , set SMTP CLIENT ON and go back using the “M” command. If you are testing, set the direct mode, if you are working with the Charon I&II DB, you can stay in the SHIFT mode and use DIP switches as a binary inputs. The Gateway MUST be different then outgoing SMTP address. If these two addresses are the same, set the Gateway to 0.0.0.0, so the SMTP server is accessible only in local network.Set the SMTP IP address using the S: Telnet/SMTP Server IP IP command. The SMTP server must be accessible on this IP on port 25.
Use the X: E-Mail settings command to set your own e-mail sending conditions. The mask means, that there will be done the logical AND between the mask and input port. The pattern defines the result after the AND is done. So, the conditions works as follows: The P1 value AND MASK is equal to PATT, than send the e-mail.
Serial Converter – TCP port 23
If the connection with the module is opened (for example from the Telnet application)on the port 23, all the data received by the module on port 23 are sent to the module’s RS-232 line and all the data, received by the module on it’s RS-232 line are sent to the Ethernet. The receiving device is set in the SETUP mode (outgoing IP address). There MUST be set the right Server/Client option in the SETUP mode. If the module does not sends or receives any character in 50 seconds, the TCP connection is closed by the module. The RS-232 communication mode is set also in the SETUP mode.
The limitations of the RS-232 line converter
- · The Applications supports only one TCP connection in the same time. So, you cannot access the RS-232 line on port 23 and control the I/O pins on port 26 in the same time. The WWW service is independent and should work, if any of these two TCP connections is working
I/O Controller lite – TCP port 26
All
the inputs, outputs and controlled peripheries has its own ID. Each
periphery can has an alias of 5 bytes. For example, the first thermometer
has a default alias “term1” and ID 16. This ID number is useful for
the remote control.
The texts of each alias might be changed in the SETUP mode. The alias cannot be changed, if the application is running.
The Alias is used by the Controller with the “$” character, while
the ID is signed by “#”.
The syntax of the Controller’s commands
There is used the following syntax for the remote control: port.command <enter>port Defines, which device is going to be used for the command. The ID can be defined in the following ways:
- #<ID> for example “#16“ if working with the first thermometer
- $<alias> for example „$term2“ if working with the first thermometer
command Specifies the command, which would be done
- ? – The state info
-for example „#16.?“ – displays the state of the ID=16
-for example „$in1.?“ - displays the state of the first binary input ID=1
- s<string> - Other settings (for example displaying
a text on the LCD)
- for example „#24.sHallo“ displays the text Hallo on the first LCD’s line
- 1 – sets the binary output to the log. 1
- for example „#8.1“ sets the out1 (first binary output) to the log. 1.
- 0 - sets the binary output to the log. 1
- for example „$rea.0“ sets ID=14 (seventh binary output) to the log. 0.
Note: In case, there was set the „IP mode“ in the SETUP, there will be displayed „!-Read Only“ if you are trying to write on the second line of LCD.
