1 Overview
1.1 Overview
Along with the development of the Internet, the demand for data communication
functions has increased recently. Data communication over the Internet requires using
TCP/IP, the Internet communication protocol. That is to say, in order to connect a system to
the Internet, TCP/IP protocol must be implemented. It is possible to implement TCP/IP by
directly implementing the protocol, porting open TCP/IP in public or using Operating
System (OS). However, all these methods impose burdens on the developer in time, cost,
and technology.
ezTCP series, a Serial ↔ TCP/IP protocol converter product group of Sollae Systems,
enables you to use TCP/IP communication (the Internet communication) function simply by
“connecting the cable to a serial port”. ezTCP sends data from the serial port to the Internet
network after TCP/IP processing, and vice versa.
CSE-M32 in ezTCP product group is a product that provides TCP/IP communication
through Ethernet. In other words, like other ezTCP products, CSE-M32 sends data from the
serial ports to the LAN after TCP/IP processing and vice versa.
As CSE-M32 has 2 UART ports so that it supplies TCP/IP functions to two UART devices.
And because one UART port support the TCP speed of about 1.8Mbps, CSE-M32 is very
useful for the high speed communication device.
It provides DHCP and PPPoE functions, so that it can be applied to the cable network
and the xDSL network. And it has DDNS (Dynamic DNS) function, so it can be used more
easily in the internet.
It also provides debugging function, so user can solve the problem with ours.

2.4.4 Flow Control
CSE-M32 support RTS/CTS Hardware Flow Control. RTS pin is for notifying connected
serial devices that its buffer can be available to receive data. CTS pin is for checking that
the RTS signal of its counterpart. To use this control CSE-M32 should be set to the type of
serial communication is RS232.
2.4.5 Telnet COM Port Control Option (RFC2217)
CSE-M32 has Telnet COM Port Control Option function that is specified by RFC2217. If
the Telnet COM Port Control Option is enabled, CSE-M32 sends the CTS control signal to
the communication counterpart, and CSE-M32 sets its serial port items (RTS, baud rate,
data bits, parity, stop bit) after getting information from the communication counterpart.
2.4.6 Disable TCP Transmission Delay
If you use this option, CSE-M32 sends the data from the serial port to Ethernet as quickly
as possible.
2.4.7 TX interval
This option is for preventing data loss in the case that the serial device has very small
buffer size or doesn’t have a buffer. The range of the value could be from 0 to 25 and the
unit is duration of sending 1 byte. For example, if you set this value to 5, each byte will be
transferred with duration of sending 5 bytes.

4 Configuring IP Address and Variables
4.1 IP Address and Environmental Variables
For TCP/IP communication, you must set IP address related items. In addition, you have
to set serial port related items (serial port type, communication speed, data bit length,
parity bit, flow control, etc) to CSE-M32.
You can set the IP address and the serial port related items by using ezManager, the
supplied configuration utility which allows you to configure your CSE-M32 over the network,
or by using AT commands in ATC mode.
4.2 Configuration with ezManager
4.2.1 ezManager
The basic environmental variables (IP address related items, serial port items, and etc.)
can be set by ezManager which is an integrated management tool for Windows.
ezManager is operated in Microsoft Windows(Windows 2000 Pro, ME, XP Pro/Home,
Vista, 7). Following is the screen shot of ezManager which is just launched.
ezManager communicates UDP broadcast and its UDP ports are 50005 and
50006. Port number 50005 is for setting and port number 50006 is for debugging.
If you use any firewall function, the ports have to be opened.

4.2.4 Matters to be attended to
ezManager can be used when you want to change your device’s environment variables.
In case of CSE-M32, two interfaces are supported and those are Ethernet and RS232 port.
⚫ Using Ethernet Port
For use ezManager through Ethernet, CSE-M32 should be connected with PC on
networks. If they are located at the same network, [Search All], on the [MAC] tap, could be
used with MAC address. If they are connected on Internet, [Read], on the [IP] tap, could be
used.
⚫ Using RS232 Port
For use ezManager through RS232, not only the CSE-M32 should be connected to PC
with RS232 cross cable but also has to be operated as serial configuration mode.
4.3 AT command
In ATC mode, the user can set environment variables through the serial port using AT
command.
For more information, See “6.3 ATC Mode”.
4.4 Notify IP Change
In internet environment, most host get IP addresses dynamically. In this case, it is very
hard to communicate to the host because the IP address is changed dynamically. The IP
Change Trap service solves this problem. There are 3 types- DDNS, TCP and UDP- for this
service.
4.4.1 DDNS (Dynamic Domain Name System)
If the CSE-M32 obtains its IP address, it notices to the service provider. Then the service
provider serves DNS service. So, even though user doesn’t know the CSE-M32’s IP address,
user can connect to the CSE-M32 by the host name (after DNS looking up.) The DDNS
service provider that the CSE-M32 supports is only Dyndns (https://dyn.com/dns/) currently.
All about service usage of an account could be changed according to the
policy of DynDNS.

4.4.2 TCP/UDP
In addition, CSE-M32 can transmit some information to user’s TCP/UDP servers each
period which is set. This information is IP address, MAC address, product ID, firmware
version, and comment. The data can be sent as either ASCII or Hexadecimal type.
For more details about the Notify IP Change, please refer to the document on

5 Operation Mode
5.1 Operation Mode Overview
5.1.1 Overview
CSE-M32 can operate in one of three modes (normal, serial configuration and ISP modes).
Normal mode is ordinary data communication mode; and serial configuration mode is a
configuration mode through the serial port; and ISP mode is used to download CSE-M32
firmware through the Ethernet port.
5.2 How to Initiate Each Operation Mode
5.2.1 Normal Mode
Normal mode is a mode in which CSE-M32 performs its original functions. If the ISP- pin
keeps High, CSE-M32 is operated in this mode.
For more information, see “6. Normal Communication Mode.”
5.2.2 How to Initiate the Serial Configuration Mode
Inputting low signal to the ISP- pin from 20ms to 1000ms, CSE-M32 works in the serial
configuration mode.
5.2.3 How to Initiate the ISP Mode
The CSE-M32 checks its ISP- pin when it boots up. If the ISP- pin is High it operates as
Normal Mode and if ISP- pin is Low it operates as ISP mode that is firmware download
mode. So user has to pull down the ISP- port for ISP mode.
The ISP- pin is pulled up internally. So it operates as Normal Mode if the pin is open.
5.2.4 Comparison of Operation Modes
The following table is the comparison of the above described operation modes.

TCP protocol requires connection process. The connection is always established as 1:1
connection. At this time, the host waiting for connection (passive connection) is called a
server and the one attempting to connect (active connection) is called a client.
On the other hand, UDP communicates by block unit without connection process. As
UDP does not require connection, numbers of hosts can communicate at the same time.
5.4 Serial Configuration Mode
This mode is for configuration under condition which the network is unavailable. When
entering this mode, parameters of CSE-M32 can be set by its COM1 port. [Serial] tap on
the ezManager let users do this.

5.5 ISP Mode
5.5.1 Upgrading Firmware
In ISP mode, you can download a firmware (CSE-M32 operation software) provided by
our company. There is another thing in this mode. If you forget your password set before,
you can reset it by entering this mode. In ISP mode, all the security options including
ezTCP firewall are removal.
The following is the firmware downloading procedure.
⚫ Supply power with ISP- pin low, then CSE-M32 operates in the ISP mode.
⚫ Run hotflash that is supplied by us and input IP address of CSE-M32 and select the
firmware with the [FILE] menu. Then, send it with [SEND] button. (Uncheck the
[Verify firmware version] option.)
⚫ When the downloading is completed, set the ISP- pin to High and reset it in order
to enter normal mode again.
Firmware download can be implemented with ezManager whose version is
3.0A or subsequent version.

6 Normal Communication Mode
6.1 T2S – TCP Server
In T2S mode, the CSE-M32 functions as a server.
When a host connects to predefined local port, the CSE-M32 accepts a TCP
connection. When the ezTCP accepts TCP connection, then the TCP connection is
established. After connection is established, TCP/IP processing is performed on the data
coming to the serial port, which is then transmitted to the remote host. And the TCP/IP
data coming from the remote host is TCP/IP-processed and transmitted to the serial port to
establish data communication.

<T2S Mode>
6.1.1 TCP Connection
If a host connects to the pre-defined [Local Port] of CSE-M32, the host can communicate
bi-directionally.
6.1.2 Serial Data before the TCP Connection
The received serial data before the TCP connection is established will be handled based
on the [Event Byte] settings. If the [Event Byte] is 0, the data that comes to serial port of
CSE-M32 will not be recognized. If it is not 0, the serial data before TCP connection will be
temporarily saved to be sent to the host after the connection.
6.1.3 Data Transmission
When the TCP connection is established, the data communication in between the host
and the serial device will be established. Then, CSE-M32 will send data according to the
[Data Frame]. In other words, when the data comes through CSE-M32’s serial port, it will be
CSE-M32 User Manual Ver. 3.2
Sollae Systems Co., Ltd. - 12 - https://www.ezTCP.com
temporarily saved in the buffer. Then, when there is no incoming data during the
designated [Data Frame], CSE-M32 will send the saved data. If the [Data Frame] is 0, CSEM32 will send serial port’s data immediately. The unit used for the [Data Frame] is 10m
seconds, so CSE-M32 rounds down rest of the values.
6.1.4 Disconnection
When the connected host terminates the connection, or there is no data communication
during the designated [Timeout], the TCP connection will be automatically terminated. The
unit used for [Timeout] is 1 second.
6.2 COD – TCP Client
In COD mode, the ezTCP functions as a client.
When data of the pre-specified size [Event Byte] comes to the serial port, the ezTCP
attempts a TCP connection to the TCP port [Peer Port] of the preset host IP [Peer IP
Address]. If the remote host accepts the TCP connection, TCP connection will be
established. Data coming to the serial port after connection establishment is TCP/IPprocessed and transmitted to the remote host. And, data coming from the remote host is
TCP/IP-processed and transmitted to the serial port for data communication.
6.2.1 Serial Data before the TCP Connection
Data before TCP connection will be handled based on the [Event Byte] settings. If the
[Event Byte] is 0, the data that comes to CSE-M32’s serial port will not be recognized. If it is
not 0, the serial data before TCP connection will be temporarily saved to be sent to the
host after the connection.
CSE-M32 User Manual Ver. 3.2
Sollae Systems Co., Ltd. - 13 - https://www.ezTCP.com
6.2.2 Data Transmission
When the TCP connection is established, the data communication in between the host
and the serial device will be established. Then, CSE-M32 will send data according to the
[Data Frame]. In other words, when the data comes through CSE-M32’s serial port, it will be
temporarily saved in the buffer. Then, when there is no incoming data during the
designated [Data Frame], CSE-M32 will send the saved data. If the [Data Frame] is 0, CSEM32 will send serial port’s data immediately. The unit used for the [Data Frame] is 10
milliseconds, so CSE-M32 rounds down rest of the values.
6.2.3 Disconnection
When the connected host terminates the connection, or there is no data communication
during the designated [Timeout], the TCP connection will be automatically terminated. The
unit used for [Timeout] is 1 second.
6.2.4 DNS
If users set the host name instead of the IP address on the [Peer Address] box, CSE-M32
query the IP address of the host to its Domain Name Server (DNS). The IP address of DNS
can be configured on ezManager. If you set incorrect address on that box, the connection
won’t be established.

6.4 UDP
UDP has no processes of connection. In this mode, data is sent in block units. Therefore,
data that comes through CSE-M32’s serial port must be classified in block units to send it
elsewhere.
6.4.1 Key parameters
⚫ Block Size(Byte)
[Block Size(Byte)] means the size of a block in UDP mode. Its unit is byte. The size of
bytes are come into the serial port, CSE-M32 sends them as one block to the
network. The maximum value could be 1460 bytes.
⚫ Data Frame
[Data Frame] means the time for gathering data to make one block. Its unit is 10ms.
If there are no transmission during the time which is set to this value, CSE-M32 sends
gathered data in the buffer as one block to the network.
Please set this value to 11 or higher values for correct operation.
Once one of the parameters is sufficient, the block size is decided as the
condition.
⚫ Dynamic update of Peer host
If users set the value of [Peer Address] and [Peer Port] to 0, [dynamic update of peer
host] function is activated. By using this function, CSE-M32 can communicate to
multiple hosts without additional setting.
