Wiring Requirements
ATTENTION
Before connecting the hardware, follow these important wiring safety precautions:
Disconnect power source
Do not install or wire this unit or any attached devices with the power connected. Disconnect the
power before installation by removing the power cord before installing and/or wiring your unit.
Follow maximum current ratings
Calculate the maximum possible current in each power wire and common wire. Observe all
electrical codes dictating the maximum current allowable for each wire size.
If the current goes above the maximum ratings, the wiring could overheat, causing serious
damage to your equipment.
Use caution - unit may get hot
The unit will generate heat during operation, and the casing may feel hot to the touch. Take care
when handling unit. Be sure to leave adequate space for ventilation.
The following guidelines will help ensure trouble-free signal communication:
z Use separate paths to route wiring for power and devices to avoid interference. Do not run
signal or communication wiring and power wiring in the same wire conduit. The rule of
thumb is that wiring that shares similar electrical characteristics can be bundled together.

The bottom row of pins is for connecting a 5V power supply; the next row up is for connecting a
3.3V power supply. Digital I/O pins are located on the right side. The top row of pins is for
grounding.
Connecting to the Network
When developing your application, you may wish to use Ethernet to configure the WE-2100T,
especially if your wireless LAN is not functional yet. You may connect to the network using the
evaluation board’s RJ45 Ethernet port. In order to use the LAN connection, make sure the network
cable is already plugged in before the unit is powered on.
After power is connected in the next step, the RJ45 connector will indicate a valid connection to
the Ethernet as follows:
LAN
A green LED indicator indicates a valid 100 Mbps Ethernet network connection
and will flicker as data is being transmitted.
LAN
A yellow LED indicator indicates a valid 10 Mbps Ethernet network connection
and will flicker as data is being transmitted.
Connecting the Power
Connect the 12 to 48 VDC power line to the power jack on the evaluation board.
Connecting to a Serial Device
Use a serial cable to connect the serial device to the data port, P2, on the evaluation board. (P1 is
the console port, which is used for the serial console.)

DI/O Test Settings
The WE-2100T includes 9 digital I/O channels. Each digital I/O channel is a GPIO (General
Purpose I/O) channel that can be set to “digital output” or “digital input” mode by software. When
developing your own applications, be aware of the voltage limits. The output current is 1 mA.
Min. Max. Unit Conditions

The output current for each digital output channel carries only 1 mA.
On the evaluation board, the DIO mode jumper selects whether a digital channel will be connected
to the DIP switch for input testing, or to the LED for output testing. If DIO1 is set to digital input
mode on the WE-2100T, you can use a jumper setting on the evaluation board to connect DIO1 to
the DIP switch. Digit one on the DIP switch will then be the input device for DIO1. When you flip
the switch on or off, you can see the status of DIO1 change on the web console or in the Windows
utility.
1. First, position the jumpers so they correspond with the input/output mode of each digital I/O
channel. In the example below, channels 0 through 3 are output (DO) channels and channels 4
through 8 are input (DI) channels.
2. After setting the jumpers, use the DIP switches to set the status for input channels 0 through 3.
You can set the status to either lo w (on) or high (off). In the example below, channel 0 is set
to low, and channels 1 through 3 are set to high. Note that channel 0 corresponds to switch 1.

Chapter 4 Selecting an Operation Mode
In this section, we describe the available operation modes for the WE-2100T. There is a mode that
relies on a driver installed on the host computer, and other modes that rely on TCP/IP socket
programming concepts. After determining the proper operation mode for your application, please
refer to Chapter 8 for instructions on configuring that mode.
Overview
TCP Server Mode
TCP Client Mode
UDP Mode
Real COM Mode
WE-2100T Series User’s Manual Selecting an Operation Mode
4-2
Overview
The WE-2100T connects serial devices to the wireless LAN. It has a built-in TCP/IP stack that
saves you the effort of programming networking protocols. Simply select the proper operating
mode to allow your computer to access, manage, and co nfigure your serial device over the
Internet.
Traditional SCADA and data collection systems collect data from various instruments over serial
connections (RS-232/422/485). Since WE-2100T is designed to convert between serial and
Ethernet signals, both local and remote devices can be connected to a standard TCP/IP network
and made accessible to SCADA and data collection systems.
Real COM and RFC2217 modes allow serial-based software to access the module’s serial port as
if it were a local serial port on a PC. These modes are appropriate when your application relies on
Windows or Linux software that was originally designed for locally attached COM or TTY
devices. With these modes, you can access your devices from the network using your existing
COM/TTY-based software, without investing in additional software.
Three different socket modes are available for user-developed socket programs: TCP Server, TCP
Client, and UDP Server/Client. For TCP applications, the appropriate mode depends on whether
the connection will be hosted or initiated from the module’s serial port or from the network. The
main difference between the TCP and UDP protocols is that TCP guarantees delivery of data by
requiring the recipient to send an acknowledgement to the sender. UDP does not require this type
of verification, making it possible to offer speedier delivery. UDP also allows multi-unicasting of
data to groups of IP addresses and would be suitable for streaming media or non-critical messaging
applications such as LED message boards.
TCP Server Mode
In TCP Server mode, the module’s serial port is
assigned an IP:port address that is unique on your
TCP/IP network. It wai ts for the host computer to
establish a connection to the attached serial
device. This operation mode also supports up to
four simultaneous connections, so multiple hosts
can collect data from the attached device at the
same time.
Data transmission proceeds as follows:
1. A host requests a connection to the module’s
serial port.
2
. Once the connection is established, data can
be transmitted in both directions—from the
host to the device, and from the device to the
host.
WE-2100T Series User’s Manual Selecting an Operation Mode
4-3
TCP Client Mode
In TCP Client mode, the module actively
establishes a TCP connection to a specific
network host when data is received from the
attached serial device. After the data has been
transferred, the module can automatically
disconnect from the host computer through the
Inactivity time settings. Please refer to Chapter
8 for details on these parameters.
Data transmission proceeds as follows:
1. The module requests a connection from the
host.
2. The connection is established and data can
be transmitted in both directions between
the host and device.
UDP Mode
UDP is similar to TCP but is faster and more
efficient. Data can be broadcast to or received
from multiple network hosts. Howe ver , UD P
does not support verification of data and would
not be suitable for applications where data
integrity is critical. It is ideal for message
display applications.
Real COM Mode
Real COM mode is designed to work with
drivers that are installed on a network host.
COM drivers are provided for Windows
systems, and TTY drivers are provided for
Linux and UNIX systems. The driver
establishes a transparent connection to the
attached serial device by mapping a local serial
port to the module’s serial port. Real COM
mode supports up to four simultaneous
connections, so multiple hosts can collect data
from the attached device at the same time.
WE-2100T Series User’s Manual Selecting an Operation Mode
4-4
ATTENTION
Real COM drivers are installed and configured through the included Windows utility.
Real COM mode allows you to continue using your serial communications software to access
devices that are now attached to the WE-2100T module. On the host, the Real COM driver
automatically intercepts data sent to the COM port, packs it into a TCP/IP packet, and redirects it
to the network. At the other end of the connection, the WE-2100T accepts the Ethernet frame,
unpacks the TCP/IP packet, and sends the serial data to the appropriate device.
ATTENTION
In Real COM mode, several hosts can have simultaneous access control over the serial port on the
module. If necessary, you can limit access by using the Accessible IP settings. Please refer to
Chapter 9 for additional information on Accessible IP settings.

Chapter 5 Initial IP Address Configuration
When setting up your WE-2100T module for the first time, the first thing you should do is
configure the IP address. This chapter introduces the methods that can be used to configure the
WE-2100T’s IP address. For more details about network settings, please refer to Chapter 7.
This chapter includes the following sections:
Selecting an IP Address or Configuration
Assigning IP Address with Network Enabler Administration Suite
Assigning IP Address with ARP
Assigning IP Address with Telnet Console
Assigning IP Address with Serial Console
WE-2100T Series User’s Manual Initial IP Address Configuration
5-2
Selecting an IP Address or Configuration
For most applications, you will assign a fixed IP address to the module, which means that you set
the IP address directly. However, for certain network environments, your module’s IP address will
need to be assigned by a DHCP or BOOTP server. In this case, instead of directly assigning the
module’s IP address, you will need to configure the module to receive its IP address from the
appropriate DHCP or BOOTP server.
If you are not sure whether you need to configure your module for a dynamic or static IP address,
consult the administrator who set up the LAN. You will also need to consult the network
administrator if you wish to use a fixed IP address in a DHCP or BOOTP environment.
Factory Default IP Address
Network Interface IP Configuration IP Address
LAN Static 192.168.126.254
WLAN Static 192.168.127.254
If the module is configured to obtain its IP settings from a DHCP or BOOTP server but is unable
to get a response, it will use the factory default IP address and netmask.
The 192.168.xxx.xxx set of addresses are private IP addresses, since they cannot be directly
accessed from a public network. You cannot ping a device with a 192.168.xxx.xxx address from an
outside Internet connection. If your application requir es sending data over a public network, such
as the Internet, you will need to assign a valid public IP address, which can be leased from a local
ISP.
Assigning IP Address with Network Enabler Administration
Suite
Please refer to Chapter 12 for instructions on using Network Enabler Administrator to configure
and manage your WE-2100T embedded module.
Assigning IP Address with ARP
The ARP (Address Resolution Protocol) command can be used to assign an IP address to the
module. The ARP command tells your computer to associate the module’s MAC address with the
specified IP address. You must then use Telnet to access the module, at which point the module’ s IP
address will be reconfigured. This method only works when the module is configured with default
IP settings.
ATTENTION
When using ARP to set the module’s IP address, be aware of the following items:
z Your computer and your module must be connected to the same LAN or WLAN. You may use
a cross-over Ethernet cable to connect the module directly to your computer’s Ethernet port.
z Your module must be configured with the factory default IP address before executing the ARP
command. When connected to a LAN, the default IP is 192.168.126.254. When connected to a
WLAN, the default IP is 192.168.127.254.
WE-2100T Series User’s Manual Initial IP Address Configuration
5-3
1. Select a valid IP address for your WE-2100T module. Consult with your network
administrator if necessary.
2. Obtain the module’s MAC address from the label on the module.
3. From the DOS prompt, execute the arp -s command with the desired IP address and the
module’s MAC address, as in the following example:
arp -s 192.168.200.100 00-90-E8-xx-xx-xx
In this example 192.168.200.100 is th e new IP address that you wish to assign to the module,
and 00-90-E8-xx-xx-xx is the module’s MAC address.
4. From the DOS prompt, execute a special Telnet command using port 6000, as in the
following example:
telnet 192.168.200.100 6000
In this example, 192.168.200.100 is the new IP address that is being assigned to the module.
5. You should see a message indicating that the connection failed.
6. The module will automatically reboot with the new IP address. You can verify that the
configuration was successful by connecting to the new IP address with Telnet, ping, or
another method.
Assigning IP Address with Telnet Console
Depending on how your computer and network are configured, you may find it convenient to use
network access to set up your WE-2100T module’s IP address. T his can be done using the Telnet
program.
1. Select Run… from the Windows Start menu.
2. Enter the telnet command using your module’s current IP address and click OK.

10. Press Enter to restart the module. It will reboot with the new IP settings.
Assigning IP Address with Serial Console
You may use the module’s console port to configure the IP address. As soon as the connection is
open, you will be presented with a text menu identical to the Telnet console.
1. Connect your PC’s serial port to the module’s console port. On the evaluation board, the
console port is P1.
2. Open your terminal emulator program, such as Windows HyperTerminal. We recommend
using PComm Terminal Emulator, which can be downloaded for free at www.moxa.com.
3. In your terminal emulator program, configure the communication parameters for the serial
port on the PC. The parameters should be set to 19200 for baud rate, 8 for data bits, None for
parity, and 1 for stop bits.

DNS Server 1 and 2
Default
Options
IP address (e.g., “192.168.1.1”)
Description
This field is for the DNS server’s IP address, if applicable. With the DNS server
configured, the WE-2100T module can use domain names instead of IP
addresses to access hosts.
Domain Name System (DNS) is how Internet domain names are identified and
translated into IP addresses. A domain name is an alphanumeric name, such as
www.moxa.com, that it is usually easier to remember than the numeric IP
address. A DNS server is a host that translates a text-based domain name into an
IP address in order to establish a TCP/IP connection. When the user wants to
visit a particular website, the user’s computer sends the domain name (e.g.,
www.moxa.com) to a DNS server to request that website’s numeric IP addr ess.
When the IP address is received from the DNS server, the user’s computer uses
that information to connect to the website’s web server.
The WE-2100T will play the role of a DNS client, actively querying the DNS
server for the IP address associated with a particular domain name.

Options
IP address (e.g., “192.168.1.1”)
Description
This field is for the IP address that will be assigned to your WE-2100T module.
An IP address is a number assigned to a network device (such as a computer) as
a permanent address on the network. Computers use the IP address to identify
and talk to each other over the network. Choose a proper IP address that is
unique and valid in your network environment. If your module will be assigned
a dynamic IP address, set the “IP configuration” parameter appropriately.
Netmask
Default
255.255.255.0
Options
Netmask setting (e.g., “255.255.0.0”)
Description
This field is for the subnet mask. A subnet mask represents all of the network
hosts at one geographic location, in one building, or on the same local area
network. When a packet is sent out over the network, the WE-2100T module
will use the subnet mask to check whether the desired TCP/IP host specified in
the packet is on the local network segment. If the address is on the same
network segment as the module, a connection is established directly from the
module. Otherwise, the connection is established through the gateway as
specified in the “Gateway” parameter.
Gateway
Default
Options
IP address (e.g., “192.168.1.1”)
Description
This field is for the IP address of the gateway, if applicable. A gateway is a
network computer that acts as an entrance to another network. Usually, the
computers that control traffic within the network or at the local Internet service
provider are gateway nodes. The WE-2100T module needs to know the IP
address of the default gateway computer in order to communicate with the hosts
outside the local network environment. Consult your network administrator if
you do not know how to set this parameter.
Speed
Default
Auto
Options
Auto, 10Mbps Half, 10Mbps Full, 100Mbps Half, 100Mbps Full
Description
This field specifies the network speed for the built-in Ethernet connection.
IEEE802.3 Ethernet supports auto negot ia t i o n of transfer speed. However , some
switches/hubs require that the communication speed be fixed at 100Mbps or
10Mbps.
ATTENTION
In dynamic IP environments, the WE-2100T will send 3 requests every 30 seconds to the DHCP
or BOOTP server until the network settings have successfully been assigned. The first request
will time out after one second; the second request will time out after three seconds, and the third
request will timeout after five second. If the DHCP or BOOTP serv er is un available, the
WE-2100T will use the factory default network settings.

provider are gateway nodes. The WE-2100T module needs to know the IP
address of the default gateway computer in order to communicate with the hosts
outside the local network environment. Consult your network administrator if
you do not know how to set this parameter.

Infrastructure Mode, Ad-hoc Mode
Description
This field specifies whether the WE-2100T will operate in Ad-hoc or
Infrastructure Mode. For all wireless networking devices, there are two possible
modes for communication with another wireless device. Devices that are
configured for Ad-hoc Mode automatically detect and communicate directly
with each other and do not require a wireless access point (AP) or gateway.
Wireless devices that are configured for Infrastructure Mode do not
communicate directly with each other, but through a wireless access point (AP).
Devices can only communicate with devices operating in the same mode.
Devices in Ad-Hoc Mode cannot communicate with devices in Infrastructure
Mode.
Example of Ad-Hoc Mode
Example of Infrastructure Mode
After setting the Network type, you will need to adjust the General and

Options
Auto, 802.11a, 802.11b, 802.11g
Description
This field determines which wireless standard will be used by the selected
profile. 802.11a, 802.11b, and 802.11g are supported.
Auto: In Ad-hoc Mode, the WE-2100T will scan the 2.4G wireless band and
will automatically select the appropriate wireless standard for communication
with any other wireless devices that are detected. In Infrastructure Mode, the
WE-2100T will automatically select between 802.11a, 802.11b and 802.11g
according to the settings of the AP.
802.11a: This setting is only available in Infrastructure Mode. The Unlicensed
National Information Infrastructure (UNII) 5 GHz band is used for
communication, which is different from the RF band used by 802.11b and
802.11g. Consequently, 802.11a devices will not be able to communicate with
802.11b or 802.11g devices. (Multi-mode 802.11a/b/g APs or client adapters can
be used to resolve this.) Transmission rates up to 54Mbps are supported.
802.11b: This is the well-known “Wi-Fi” standard, also referred to as “802.11
High-Rate (HR)”. Wireless communication is in the 2.4 GHz ISM band, using
the DSSS spread spectrum transmission scheme. 802.11b supports data rates of
1 Mbps, 2 Mbps, 5.5 Mbps, and 11 Mbps.
802.11g: This is currently the most widely used standard for wireless LANS and
is sometimes referred to as “54g™”. Communication is in the 2.4 GHz ISM
band and uses Orthogonal Frequency Division Multiplexing (OFDM). Data
rates up to 54 Mbps are supported.
SSID

Authentication
Default
Open System
Options
Open System, Shared Key, WPA, WP A-PS K, WPA2, WPA2-PSK
Description
This field specifies how wireless devices will be authenticated. Only
authenticated devices will be allowed to communicate with the WE-2100T. If a
RADIUS server is used, this setting must match the setting on the RADIUS
server.
Open System: The WE-2100T will simply announce a desire to associate with
another station or access point. No authentication is required. For Ad-hoc Mode,
this is the only option for authentication, since Ad-hoc Mode was designed for
open communication.
Shared Key: This option is only available in Infrastructure Mode.
Authentication involves a more rigorous exchange of frames to ensure that the
requesting station is authentic. WEP encryption is required.
WPA: This is a managed authentication option that is only available in
Infrastructure Mode. WPA was created by the Wi-Fi Alliance, the industry trade
group that owns the Wi-Fi trademark and certifies devices with the Wi-Fi name.
It is based on Draft 3 of the IEEE 802.11i standard. Each user uses a unique key
for authentication, distributed from an IEEE 802.1X authentication server, also
known as a RADIUS server. This option is also referred to as WPA Enterprise
Mode, since it is intended to meet rigorous enterprise security requirements.
Tunneled authentication is supported, depending on the EAP method selected.
WPA-PSK: This is an unmanaged authentication option that is only available in
Infrastructure Mode. Instead of a unique key for each user, a pre-shared key
(PSK) is manually entered on the access point to generate an encryption key
that is shared among all users. Consequently, this method does not scale well for
enterprise. A PSK that uses a mix of letters, numbers and non-alphanumeric
characters is recommended. This option is also referred to as WPA Personal
Mode, since it is designed for the needs and capabilities of small home and
office WLANs.
WPA2: This is a managed authentication option that is only available in
Infrastructure Mode. WPA2 implements the mandatory elements of 802.11i.
Supported encryption algorithms include TKIP, Michael, and AES-based
CCMP, which is considered fully secure. Since March 13, 2006, WPA2 has been
mandatory for all Wi-Fi-certified devices. This option may also be referred to as
WPA Enterprise Mode. Tunneled authentication is supported, depending on the
EAP method selected.
WPA2-PSK: This is an unmanaged authentication option that is only available
in Infrastructure Mode. It employs WP2 encryption algorithms but relies on a
PSK for authentication. A PSK that uses a mix of letters, numbers and
non-alphanumeric characters is recommended. This option can also be referred
to as WPA Personal Mode.

Encryption
Default
Disable
Options
Disable, WEP, TKIP , AES-CCMP
Description
This field specifies the type of encryption to use during wireless
communication. Different encryption methods are available depending on the
Authentication setting. Also, each encryption method has its own set of
parameters that may also require configuration.
Disable: No encryption is applied to the data during wireless communication.
WEP: Wired Equivalent Privacy (WEP) is only available for Open System and
Shared Key authentication methods. Data is encrypted according to a key. The
WE-2100T supports both 64 and 128-bit keys. This method may deter casual
snooping but is not considered very secure.
TKIP: Temporal Key Integrity Protocol (TKIP) is only available for WPA,
WPA2, WPA-PSK, and WPA2-PSK authentication methods. TKIP is part of a
draft standard from the IEEE 802.11i working group and utilizes the RC4
stream cipher with 128-bit keys for encryption and 64-bit keys for
authentication. TKIP improves on WEP by adding a per-packet key mixing
function to de-correlate the public initialization vectors (IVs) from weak keys.
AES-CCMP: This is a powerful encryption method that is only available for
WPA, WPA2, WPA-PSK, and WPA2-PSK authentication methods. Advanced
Encryption Standard (AES) is the block cipher system used by the Robust
Secure Network (RSN) protocol and is equivalent to the RC4 algorithm used by
WPA. CCMP is the security protocol used by AES, equivalent to TKIP for
WPA. Data undergoes a Message Integrity Check (MIC) using a well-known
and proven technique called Cipher Block Chaining Message Authentication
Code (CBC-MAC). The technique ensures that even a one-bit alteration in a
message produces a dramatically different result. Master keys are not used
directly but are used to derive other keys, each of which expire after a certain
amount of time. Messages are encrypted using a secret 128-bit key and a 128-bit
block of data. The encryption process is complex, but the administrator does not
need to be aware of the intricacies of the computations. The end result is
encryption that is much harder to break than even WPA.
PSK Passphrase
Default
Options
free text (e.g., “This is the WLAN passphrase”)
Description
This field is only available for WPA-PSK and WPA2-PSK authentication
methods. If the WE-2100T’s passphrase does not match the AP’s passphrase, the
connection will be denied. A PSK of sufficient strength—one that uses a mix of
letters, numbers and non-alphanumeric characters—is recommended.

Security Settings for WPA, WPA2
When WPA or WPA2 is used for authentication, you will also need to configure EAP method in
the Security settings for the WLAN profile. Other settings will also be displayed depending on
how EAP method is configured.
There are two parts to WPA and WPA2 security, authentication and data encryption.
z Authentication occurs before access is granted to a WLAN. Wireless clients such as the
WE-2100T are first authenticated by the AP according to the authentication protocol used by
the RADIUS server. Depending on the WLAN security settings, an EAP tunnel can be used to
scramble the username and password that is submitted for authentication purposes.
z Encryption occurs after WLAN access has been granted. For all wireless devices, data is first
encrypted before wireless transmission, using mutually agreed-upon encryption protocols.

EAP Method
Default
PEAP
Options
TLS, PEAP, TTLS, LEAP
Description
This field specifies the EAP method to use for authentication. Four methods are
supported.
TLS: Transport Layer Security (TLS) was created by Microsoft and accepted by
the IETF as RFC 2716: PPP EAP TLS Au thentication Protocol. Passwords and
tunneled authentication are not used. A user certificate and user private key are
used to identify the WE-2100T. The WE-2100T’s user certificate and user
private key must already be installed on the RADIUS server.
PEAP: Protected Extensible Authentication Protocol (PEAP) is a proprietary
protocol which was developed by Microsoft, Cisco and RSA Security.
TTLS: Tunneled T ransp ort Layer Security (TTLS) is a proprietary protocol
which was developed by Funk Software and Certicom, and is supported by
Agere Systems, Proxim, and Avaya. TTLS is being considered by the IETF as a
new standard. For more information on TTLS, read the draft RFC EAP
Tunneled TLS Aut hentication Protocol.
LEAP: Lightweight Extensible Authentication Protocol (LEAP) is a proprietary
protocol which was developed by Cisco. LEAP doesn’t check certificate during
the authentication process.

8-4
TCP Alive Check Time
Default
7 min
Options
0 to 99 min
Description
This field specifies how long the module will wait for a response to “keep alive”
packets before closing the TCP connection. The module checks connection
status by sending periodic “keep alive” packets.
0: The TCP connection will remain open even if there is no response to the
“keep alive” packets.
1 to 99: If the remote host does not respond to the packet within the specified
time, the module will force the existing TCP connection to close.
Max Connection
Default
1
Options
1 to 4
Description
This field specifies the maximum number of connections that will be accepted
by the serial port.
1: Only one specific host can access this serial port, and the Real COM driv er
on that host will have full control over the port.
2 to 4: This serial port will allow the specified number of connections to be
opened simultaneously. With simultaneous connections, the Real COM driver
will only provide a pure data tunnel with no control ability. The serial
communication will be determined by the module rather than by your
application program. Application software that is based on the Real COM driver
will receive a driver response of “success” when using any of the Win32 API
functions. The module will send data only to the Real COM driver on th e host.
Data received from hosts will be sent to the attached serial device on a
first-in-first-out basis.
ATTENTION
When Max connection is 2 or greater, the serial port’s communication settings (i.e., baudrate,
parity, data bits, etc.) will be determined by the module. Any host that opens the COM port
connection must use identical serial communication settings.

Delimiter 1 and 2
Default
Disabled
Options
Disabled, Enabled, 00 to FF
Description
These fields are used to define special delimiter character(s) for data packing.
Enable Delimiter 1 to control data packing with a single character; enable both
Delimiter 1 and 2 to control data packing with two characters received in
sequence.
When these fields are enabled, serial data will accumulate in the serial port’s
buffer until the buffer is full or until the specified delimiter character(s) are
received. For example, the carriage return character could be used as a delimiter
in order to transmit each sentence or paragraph in a separate pack et.
Delimiters must be incorporated into the data stream at the software or device
level.
Force Transmit
Default
0 ms
Options
0 to 65535
Description
This field controls data packing by the amount of time that elapses between bits
of data.
0: If serial data is not received, the module will wait indefinitely for additional
data.
1 to 65535: If serial data is not received for the specified amount of time, the
data that is currently in the buffer will be packed for network transmission. The
optimal force transmit time depends on your application, but it must be at least
larger than one character interval within the specified baudrate. For example,
assume that the serial port is set to 1200 bps, 8 data bits, 1 stop bit, and no
parity. In this case, the total number of bits needed to send a character is 10 bits,
and the time required to transfer one character is 8.3 ms, so the force transmit
time to be larger than 8.3 ms.
Settings for RFC2217 Mode
