Overview
Applications
The FMod-TCP BOX is a TCP/IP server that allows system integrators to
connect different devices such as home appliances, industrial sensors and
industrial control systems directly to the Ethernet network, (10BaseT) and to
remotely monitor and control those using standard protocols.
It can either be accessed through a TCP socket connection, from a
computer, or through a simple Web Page in a standard browser which can
be directly loaded to the device (max 44kb). The module is delivered with a
default web page including a Java Applet that enables the controlling of the
device.
The connection between this device and the user's product can be done
through the following interfaces:

Software operating principle
The operating principle for PC softwares that must exchange data with an
FMod-TCP BOX device depends on which interface is used.
In case of RS232 use, the operation is really simple. Any byte sent to port
TCP #8000 will be redirected to the serial bus and any byte received from
the serial bus will be redirected to the TCP connection.
In the other cases (I/O, A/D and I2C), the software has to use a dedicated

SOS button
A button is dedicated to restore default IP address or factory settings.
There are tow possible scenarios:
ƒ If you press it while the device is running, the IP address will be
restored as soon as all TCP connections are closed. Warning: you
have to send the Save Settings command to the device in order to save it
into EEPROM.
ƒ If the button is pressed during startup, the default IP address and
factory settings of all parameters will be restored AND saved into
EEPROM. In this case, you do not need to send the Save Parameters
command.

Quick start
This section is intended to help users to quickly plug the module into their
system and establish a connection between the computer and the device.
You can find the device’s factory communication settings on the following
label.
FMOD-TCP BOX
INPUT(supply) : 5-32V DC, max 3A
MAC: 00-50-C2-30-xx-xx / IP : 169.254.5.5
This device is not intended to be used in a medical, life-support or space product. Any failure
of this device that may cause serious consequences should be prevented by implementation
of backup systems. The user agrees that protection against consequences resulting from
The Ethernet MAC Address is fixed and cannot be changed. The IP Address
can be changed. The complete procedure is described below.
Note: If the device has already been configured and the IP address has been
changed to an unknown value, you can retrieve an SOS IP address (the one on
label) by pressing the “SOS button” during the normal operation of the device.
Changing IP address
To easily change the factory IP address, use the Win32 software provided on
the CD-Rom.
1. Plug your new device on your PC network.
2. Start the Win32 application.
3. Click on "File->Easy change IP address".
4. The software will scan the network and display a list of all FiveCo's
devices found.
5. Select the MAC address corresponding to your new device.
6. If you have more than one network adapter on your PC, the
software will ask you to select the one which is connected to the
same network as the FMod-TCP BOX.
7. The software will suggest a new IP address with the last byte left
open. Choose a new IP (Not already used on your network!!) and
click the "Change IP address" button.
That’s it! The device has a new address and a new subnet mask (the same as
your PC). They are automatically saved into EEPROM.

You can now connect the device with the Win32 software or open its web
page by typing its new IP address into a web browser.
Notes:
ƒ The IP address won't be changed if a TCP connection exists with the
device.
ƒ The protocol used to change the IP address is described later in this
manual.

Controlling the FMod-TCP BOX by TCP or UDP
General Information
All the device's parameters (configuration registers) and features can be
accessed through a TCP or UDP port.
In addition, an HTTP-TCP port is available for web pages downloading and
another TCP port for RS232 bus access.
Those ports are:
ƒ TCP Port #80 for HTTP communication.
ƒ TCP Port #8000 for RS232 transceiver.
With regards to TCP connections, the device allows up to 4 simultaneous
connections.
These ports are described below.
RS232 (TCP # 8000)
The RS232 bus of the microcontroller is accessible through the TCP port
number 8000. The module acts simply as a transceiver for this port. Any
byte sent from the network (ex: TCP-IP from a PC) to the module will be
sent to the other side’s RS232 bus, and vice versa. Thus there is no particular
protocol dedicated to this feature. See later chapters to know how to
change parameters such as baud rate and hardware flow control.
Note: This port supports only one user at a time.
RS232 fixed settings: No parity / 1 Start Bit / 8 Data Bits / 1 Stop Bit
Important note about baud rate greater than 9600bds:
Common TCP/IP stacks (on PC, Unix station …) use a delay of 200ms for
the acknowledgement of the TCP received data packets. This is done to
reduce traffic on the network because TCP allows the acknowledgement of
several packets at one time.
Unfortunately, the FMod-TCP BOX device needs this acknowledgement to
remove the data from its internal RS232 receive buffer (if no acknowledge is
received from the PC, the module will resend those data).
FMod-TCP User Manual v.2.8
Download from Www.Somanuals.com. All Manuals Search And Download.
13 / 58
So, with speeds greater than 9600bds, the buffer may be filled faster than
data can be sent by TCP and part of those will be lost if no RS232 hardware
flow control is used between the FMod-TCP BOX and the RS232 device
(CTS and RTS lines).
If you cannot use hardware flow control on RS232 bus and you have to get
more than 2048 bytes at one time, the solution is to reduce the TCP
acknowledgement delay on your computer.
For WindowsTM 2000/XP users, you can add/change the following value in
the registry. BEWARE: improperly changes done in the Windows registry can
results in a system crash! Such changes are the user’s full responsibility!
Entry: HKey_Local_Machine\SYSTEM\CurrentControlSet\Services\
Tcpip\Parameters\Interfaces\Interface-name
Key:
TcpDelAckTicks
Value: DWORD with value 0x00
The interface-name is the registry name (32 digits number) of your Ethernet
card which you use to access the module.
The following web page describes this feature in details:
Device parameters and I/O, A/D and I2C features (TCP # 8010 or UDP # 7010)
The main TCP port number 8010 or UDP port number 7010 can be used
to change some important parameters of the module:
ƒ TCP timeout value
ƒ IP address
ƒ Subnet mask
ƒ Module name
ƒ Baud rate and flow control
ƒ I2C speed
The user should use the Win32 application enclosed in the package or the
default java applet loaded in the module to change those parameters. If the
user wants to change the parameters by himself, the protocol is defined
below.
This port is also used to access Inputs and Outputs value, A/D conversion
result registers (see page 34 for a complete description of those registers)
and I2C bus. The I2C feature is described after “registers access feature”.
The last feature accessible through this port is the "Easy IP config" that is used
in the "Quick start" chapter of this document.

Registers access feature
TCP/IP works in big endian: most significant byte first, followed by least
significant byte.
The access to the data is done through an easy (6 byte header) protocol
over TCP.
Structure of each packet:
1. Function ID (2 bytes),
2. Transaction ID (2 bytes)
3. Length of the parameters (2 bytes)
4. Parameters (X byte)
5. Checksum (2 bytes) (described later in this chapter)
The user (sender) defines the values of the Transaction IDs himself. The
module that receives a command sends back an answer (for every
command). The answer contains the same Transaction ID as the
corresponding command sent. The user is also able to check execution of
each command.

I2C feature
The Inter-IC bus, commonly known as the I²C bus, is a control bus that
provides the communications link between integrated circuits in a system.
Developed by Philips in the early 1980’s, this simple two-wire bus has
become the de facto worldwide standard for system control, finding its way
into everything from temperature sensors and voltage level translators to
EEPROMs, general-purpose I/O, A/D and D/A converters, CODECs, and
microprocessors of all kinds.
You can find the I2C’s specifications on the Philips web site at the following

Note that the max length of those sequences is 180 bytes. Pay close
attention to building sequences that do not exceed this and not to ask too
much byte in answer !
The FMod-TCP BOX translates automatically those sequences to I2C
sequences. It is mandatory that the sequence has to be transmitted within
one TCP packet. Otherwise, the FMod-TCP BOX will ignore it.

Note:
If there is no address in the I2C Scan command, the FMod-TCP BOX will

I2C speed change (advanced features)
The I2C bus speed can be changed at any time by changing the content of
the I2CSPD parameter.
Beware:
1. Do not change I2C speed if it is not mandatory. Speed greater than
100kHz are not supported by all I2C slaves.
2. Do not change I2C speed during I2C communication.

18 / 58
3. The I2C controller does not match all I2C specifications at speed
higher than 100kHz. This feature will therefore not work with all I2C
slaves.
The value of the I2CSPD parameter must be computed with the following
formula:
107
I2CSPD =
−1
I2CSpeedwanted
The I2C speed cannot be saved in EEPROM.

Easy IP address config (UDP # 7010)
A really useful feature of the UDP port #7010 is the "Easy IP config" one.
The user who wants to design his own software can use this feature to do a
"quick start/install" method. Indeed, since this protocol uses a broadcast UDP
packet, even if the device is not in the same subnet, it should receive its new
IP address and subnet mask.
Procedure:
Send a UDP broadcast message (using a local or direct broadcast IP address)
to your network (inside which the FMod-TCP BOX is connected) with the
following command:

Checksum calculation
This checksum is the same as the IP checksum.
Definition: sum of 1’s complement of all 16 bits words of whole message
(FiveCo packet) except checksum bytes.
Note: all values are unsigned!
Sequence:
1. Clear accumulator
Loop
x. Only if last word is not made of two bytes, the data byte is the upper byte (big endian)
2. Compute 1’s complement of each 16bits word, result is 16bits
3. Convert last result from 16 bits to 32 bits, result is 32bits: 0x0000+last result
4. Add last result to the 32 bits accumulator
Try the Loop
5. Convert accumulator in two 16bits words
6. Add those two 16bits words, result is 16bits word.
7. If an overflow occurs with the last addition (Carry), add 1 to the last result.
8. Last result is the final result
Example (in hexadecimal):
!0x0021 (0XFFDE) Æ 0x0000FFDE (Read)
+!0x1234 (0xEDCB) Æ 0x0001EDA9 (TransID)
+!0x0003 (0xFFFC) Æ 0x0002EDA5 (3 reg to read)
+!0x0A10 (0XF5EF) Æ 0x0003E394 (reg 0A,10,02)
+!0x02(00)(0XFDFF) Æ 0x0004E193
Note that in this case a last 00 is implicitly used. (02 Æ 02 00).
0x0004 + 0xE193 = 0xE197, (carry=0)
0xE197 + carry = 0xE197
Checksum = 0xE197

Here is an example of a checksum calculation function in C:
int RetCheckSum(Byte* ByteTab, int Size)
{
// This function returns the calculated checksum
unsigned int
bool
unsigned int
Sum=0;
AddHighByte=true;
ChecksumCalculated;
for(int i=0;i<Size;i++)
{
if(AddHighByte)
{
Sum+=((ByteTab[i])<<8)^0xFF00;
AddHighByte=false;
}
else
{
Sum+=(ByteTab[i])^0x00FF;
AddHighByte=true;
}
}
if (AddHighByte==false)
Sum+= 0xFF;
ChecksumCalculated = ((Sum>>16)&0xFFFF)+(Sum&0xFFFF);
ChecksumCalculated = ((ChecksumCalculated>>16)&0xFFFF)
+(ChecksumCalculated&0xFFFF);
return ChecksumCalculated;
}
This function needs a Byte array (ByteTab) containing the command
sequence and this array’s length (Size) as input, it returns the checksum as an
int.

A specific Java Applet is provided with the module to control any of its ports
without having to write any specific code.
Overview
To connect to the http server on the device, simply open your web browser
and type the IP address of the module. Example with default address:
“http://169.254.5.5”
The applet is downloaded from the device to your computer and runs as a
local process (on your computer). You need to use an internet web
browser that is compatible with Java 1.1.
Please note that on an MSWindowsTM based computer, a few seconds delay can
occur when you download the applet due to an MSWindowsTM NetBios issue.
The navigation through the four panels of the applet is done through the
menu bar:

This application uses the IP address of your computer and its subnet mask to
find the scan broadcast address. When you click on scan, a broadcast
message will be sent to all devices in your subnet and answers will be listed.
WARNING: it only works with devices in your subnet!
How does it work?
When you click "Scan", the software simply sends a "Read registers"
command to a broadcast address on UDP port number 7010 (see chapter
The broadcast address depends on the network subnet mask present on
your PC.

The I2C interface is an easy way to test the I2C connection between the
module and the user's electronic. The user has to choose between an I2C
Read or Write operation.
In Write mode, the bytes (in hexadecimal like 41 42 45 separated by
spaces!) must be written in the dedicated line and the I2C address in the
dedicated Address space (in hexadecimal or in decimal). Then click "Send".
In Read mode, the steps are the same except that the user must specify how
many bytes have to be read. Data to write is optional (only used for
ReadAfterWrite I2C method).

The TCP timeout is a value (in seconds) after which the user will be
disconnected if the device has not been accessed in the meantime.
If the value is 0, the TCP timeout is deactivated. In this case however, if the
client crashes during connection, the communication will never be closed on
the module’s side! Because a maximum of 4 communications are allowed at
the same time on the module, one of them will be blocked. If the client
crashes four times, all of the 4 communications will be blocked and the
module will have to be reset!
The timeout for each TCP/IP connection is reloaded when there is traffic
through the port.

I2C speed setting between ~39kHz and 400kHz.
The value of this parameter must be computed with the following formula
based on the wanted speed:
107
I2CSPD =
−1
I2CSpeedwanted
Note:
Speeds greater than 100kHz have some limitations (see page 17).
Do not use a speed greater than 400kHz (<24). Greater speed will not
work.
Default value:
99 (100kHz)
Examples:
Most common speeds:
100kHz : I2CSPD = 99
400kHz : I2CSPD = 24

Description:
Voltage value of the 16 inputs pins between -12V and 12V. This value
saturates at ~ -15.5V and 24V.
Notes:
The A/D converter has a 10 bits resolution (~0.43V).
The acquisition is done every 850µs and is asynchronous with the read
access of the A/D VALUE registers. When you access this register, you get
the last A/D conversion result, which can be up to 850µs old.
