1. Introduction
The PDS-700 series is a family of Programmable Device Servers, also known as
"Serial-to-Ethernet gateway", that are designed for linking RS-232/422/485 devices to
an Ethernet network. The user-friendly VxComm Driver/Utility allows users to easily
turn the built-in COM ports of the PDS-700 series into standard COM ports on a PC.
By virtue of its protocol independence, a small-core OS and high flexibility, the PDS700 series is able to meet the demands of every network-enabled application.
The PDS-700 series includes a powerful and reliable Xserver programming structure
that allows you to design your robust Ethernet applications in one day. The built-in,
high-performance MiniOS7 boots the PDS-700 up in just one second and gives you
fastest responses.
The PPDS-700-MTCP series features true IEEE 802.3af-compliant (classification,
Class 1) Power over Ethernet (PoE) using a standard category 5 Ethernet cable to
receive power from a PoE switch like the NS-205PSE. The PPDS-700-MTCP also
works as a Modbus/TCP to Modbus/RTU gateway that supports most SCADA/HMI
communications based on the Modbus/TCP protocol. The PDSM-700 is the PDS-700
with Metal Case (RoHS) and the PPDSM-700-MTCP is the PPDS-700-MTCP with
Metal Case (RoHS). Metal Case version includes stronger protection than PDS-700
and PPDS-700-MTCP.

1.1. Why Ethernet Solutions?
Nowadays, the Ethernet protocol has become the de-facto standard for local area
networks. Via the Internet, connectivity is occurring everywhere, from home appliances, to
vending machines, to testing equipment, to UPS ...etc. An Ethernet network can link office
automation and industrial control networks, access remote systems and share data and
information between multivendor machines; it also provides a cost-effective solution for
industrial control networks.
PDS Series User Manual ( V1.4, Oct. 2009) ----- 7
Page 8
1.2. Why VxComm Technology?
In general, writing a TCP/IP program is more difficult than a COM port program, or the
COM port communication system was built many years ago.
As a result, a new technology, VxComm was developed to virtualize the COM ports
of the PDS to allow up to 256 COM Ports to be used on the central computer. The
VxComm driver saves time when accessing serial devices through the Ethernet without the
need for reprogramming the COM port software on the PC.
PDS Series User Manual ( V1.4, Oct. 2009) ----- 8
Page 9
The VxComm driver controls all the details of the Ethernet TCP/IP programming
technique; your COM port program will be able to access your serial devices through
Ethernet in the same way as through COM port with the assistance of PDS and VxComm
technology.
PDS Series User Manual ( V1.4, Oct. 2009) ----- 9
Page 10
1.3. Why Web Server Technology?
Web server technology enables configuration of the PDS via a standard web browser
interface, e.g. Internet Explorer, FireFox or Mozilla, etc. This means that it is easy to
check the configuration of the PDS via an Ethernet network without needing to install any
other software tools; thereby reducing the user’s learning carve.

2. Typical Applications for the PDS
2.1. RS-232/485/422 Device Networking
--- Using Virtual COM Technology ---
The PDS series is designed to link RS-232/485/422 devices to an Ethernet network. The
VxComm utility allows the built-in PDS COM Port to be virtualized to a standard COM
Port of the host PC as shown below:
The original COM1/2
of the host PC
COM1/2 of the PDS-
700 is mapped to
COM1/2 of the PDS-
700 is mapped to
In the configuration above, Meter-1 is virtualized to link to COM3 of the host PC.
Therefore a program original designed for the MS-COMM standard can access the meter
without any modification.
PDS Series User Manual ( V1.4, Oct. 2009) ----- 11
Page 12
2.2. Ethernet I/O Applications
The PDS series provides 2 types of Ethernet I/O solutions:
1. Linking to I-7000 series modules
2. Built-in DIO (if the module supports the DIO function)
Linking to I-7000 series modules
The I-7000 series provides a variety of I/O operations, such as D/I, D/O, A/D, D/A,
Counter and Frequency Measurement, etc. The I-7000 series was originally designed to be
used with RS-485 networks, so COM2 on the PDS-700 can be used to link to I-7000 series
modules.
By using VxComm technology, programs that on the host PC support serial devices
can be upgraded from a RS-485 network to an Ethernet network without requiring any
modifications to the program. Refer to Sec. 2.1 for more information.
Built-in DIO
The DCON protocol is a request
/reply communication. Protocol that
is defined using a simple ASCII
format, such as $AAN, $AASi6,
#AAN, etc. and is used to access
PDS and I-7000/8000/ 87k series I/O
modules.
The DCON protocol command
set for the PDS is introduced in Sec.
7. The protocol allows access the
built-in I/O through the virtual COM Ports mapped to the Port I/O of the PDS in the
VxComm Utility.
PDS Series User Manual ( V1.4, Oct. 2009) ----- 12
Page 13
2.3. Linking I-7000 Series Modules to an Ethernet Network
The I-7000 family was originally designed for use with an RS-485 network. They are
very robust and work well under the harsh industrial environments.
The PDS enables I-7000 modules to be upgraded to an Ethernet solution. Linking I7000 modules to an Ethernet combines the advantages of both RS-485 and Ethernet
solutions and expands RS-485 applications to the whole world.
The VxComm approach provides an MS-COMM-compatible interface. Therefore,
previously developed programs should still function without the need for any
modifications.
2.4. Configurable Ethernet Data Logger
Using the VxComm driver, PDS + 7000 modules can be virtualized to become COM
Port + 7000 modules located on the host-PC, and then the Data Logger in the DCON
Utility can be used to access data of I-7000 from the Ethernet. Signal data originating from
the I-7000 modules can be analyzed using MS-Excel without the need to write any custom
programs
1: The DCON utility includes a log function, as show below:
PDS Series User Manual ( V1.4, Oct. 2009) ----- 13
Page 14
2: Configure the system connection as shown below and click the “Start” button to begin
logging data.
3: Open the log file in Excel to read the log data as shown in the example below:
PDS Series User Manual ( V1.4, Oct. 2009) ----- 14
Page 15
By using the I-7000 DCON utility and MS Excel in conjunction with the VxComm
technology, the signal data of I-7000 modules from the Ethernet network can be analyzed
without the need to write custom programs. For more information about the log function
refer to the online help feature (English and Traditional Chinese) of the DCON utility.

Information related to the PDS series module can be classified into 4 main areas:
Group ID 11111: The IP address information for the PDS-700
Group ID 22222: The Baud Rate for all COM Ports
Group ID 33333: The COM Port configuration
Group ID 44444: The Connected clients and debugging information for this PDS series
module
The format for the PDS IP address information is as follows:
5-Digit LED Group ID: 11111
LED -1: indicator, which can be either 1, 2, 3 or 4
LED -2~5: IP address
TCP command port (Default = 10000)
DHCP Setting: disabled (0)/enabled (1)
The LED will initially display the Group ID, and will then display the IP address as
illustrated in the previous diagram. If the IP address is changed, the value displayed will
change immediately. The default shipping IP is 192.168.255.1 and the display sequence is
shown in the previous diagram.
The format for the COM Port Baud Rate information is follows:
5-Digit LED Group ID : 22222
LED-1: COM Port number
LED-2~5: The Baud Rate determined as (Baud Rate/100)
LED-1 displays the COM Port number, with LED-2~5 showing the Baud Rate for that
COM Port. The Baud Rate = (value shown by LED-2~5) * 100. Therefore, a COM Port
value displayed as 1.96 means that the Baud Rate of COM1 = 9600 bps; a value displayed
as 2.1152 means that the Baud Rate of COM2 = 115200 bps. The Baud Rates for all PDS
COM Ports will be shown in sequence.

The format for the COM Port configuration information is as follows:
5-digit LED Group ID: 33333
LED-1: COM Port number
LED-3: Data Bit: 5 , 6 , 7 or 8
LED-4: Parity Bit, n = no parity, E = even parity, O = odd parity
M = mark parity, S = space parity
LED-5: Stop Bit: 1 or 2
The format for the connected clients and debugging information is as follows:
5-digit LED Group ID: 44444
LED-1 will display 1, 2, 3, 4, 5 and the module name in sequence.
When LED-1 is 1, LED-2/3 indicates the number of available free sockets (default is
26 for PDS), and LED-4/5 shows the number of sockets being used by clients (default
is 0), e.g. 12600
When LED-1 is 2, LED-2~5 indicates how many times the PDS has been reset, e.g.
20002 (The PDS-700 has been reset 2 times)
When LED-1 is 3, the display indicates how many Ethernet packets are currently being
received by the PDS.
When LED-1 is 4, the display indicates that the status of the internal Flag used to
allow Ethernet packets to be sent is 0 or 1.
When LED-1 is 5, the display indicates the number of times the Ethernet chip has been
reset.
Module Name: dS.7xx
When the PDS is first powered-up or if it has just been reset, the reset state = 1. If any
client connects to the PDS, the reset state will be changed to 0. In addition, the number of
free sockets will be decreased and the number of used sockets will be increased. If the
number of free sockets is reduced to 0, then no additional clients will be able to link to the
PDS. The default number of free-sockets for the PDS is 26. Therefore, the server
(VxComm firmware or Xserver firmware) allows 26 connections to be linked to a single
PDS. Each client program occupies at least 2 connections for a single serial port, one
connection for data and another for commands.

5. Configuration with Web Browser
Once the PDS series module has been correctly configured and is networking normally,
the configuration details can be retrieved or amended using either the VxComm Utility or
a standard web browser, such as IE, FireFox, or Mozilla, etc.
5.1. Connecting to the PDS Series Module
If the COM port program is operating with a PDS, changing the
configuration will cause a program error.
Enter the IP address of the PDS series module in the Address field and press “Enter” to
connect to the PDS series module.
PDS Series User Manual ( V1.4, Oct. 2009) ----- 81

When the browser connects to the PDS, the first page that will be display is the
Firmware Information page.
5.2. Network Settings
PDS Series User Manual ( V1.4, Oct. 2009) ----- 82
Page 83
Network (TCP/IP) Setup page
IP Address
Subnet Mask
Gateway
The above three items are the most important network settings and should always
correspond to the LAN definition. If they do not match, the PDS series module will not
operate correctly. If the settings are changed while the module is operating, any links to
Virtual COM Port based applications currently in use will be lost and an error will occur.
DHCP Client : 0 = disabled, 1 = enabled
It is recommended that the DHCP Client setting is kept as disabled, and using static
network settings. This ensures your PDS always using a fixed IP address, and you don’t
need to configure the virtual COM mappings again and again.
UDP Search: 0 = disabled, 1 = always enabled.
2 = enable the UDP Search function until another client is connected. (Default = 2)
By keeping the UDP search setting as 2, the PDS loading will be reduced. The
VxComm Utility will not be able to search for this module until this module’s clients are
all disconnected.
Command Port
The default Command Port is 10000.
Web Server
Telnet Server
0 = disabled, 1 = enabled
Ping Gateway at start: 0 = disabled, 1 = enabled.
If the setting is 1 (enabled), the PDS series module will send a ping packet to the
gateway during the power-on stage. It is used to inform the gateway that a PDS (itself) has
joined the network.
TCP ACK Delay (ms), default = 50.
PDS does not want to send an empty ACK followed by a TCP data packet 1ms later,
every time. So it delays a little (TCP ACK Delay), and then can combine the ACK and
data packet into one. This efficiency reduces the number of packets and reduces network
loadings.
PDS Series User Manual ( V1.4, Oct. 2009) ----- 83
Page 84
Broadcast
1 = receive UDP broadcast packets
0 = reject UDP broadcast packets
Connection WDT timeout (ms): default = 0 (disabled), min. = 10000.
If the PDS series module does not receive any data from a client PC within the period
of the “Connection WDT timeout”, the module will close the connection to the client.
Network WDT timeout (ms): 0 = disabled, min. = 30000.
If the PDS series module does not receive any data from any of the clients within the
period of the “Network WDT timeout”, the module will reboot itself. The default setting
should be 300000ms (= 300 seconds).
This setting is the same as “SystemTimeout” setting (unit: ms) on Console/Telnet
command, and is the same as “/STxxx” in command line parameter (unit: seconds).
When user uses “config=RESET” Console/Telnet command to clear the EEPROM,
the “Network WDT timeout” (SystemTimeout, /ST) setting will also be cleared to 0.
Users have to configure this setting again by “SystemTimeout” Console/Telnet
command.
Master IP: default = empty (disabled).
If the Master IP is set, only the client using Master IP can change the COM Port
configuration. It is to prevent the COM Port configuration changed by other clients.
After setting the new configuration, click the “Set TCP/IP” button to save the new
settings to the PDS series module. If the “Reset System” option is checked, the PDS series
module will reboot itself after the saving operation is complete, otherwise the original
settings will still be valid until the next power-on.

5.3. IP filter setting
The IP filter setting limits which client PCs are able to link to the PDS series module
via specific IP addresses. When one or more IP addresses are set in the filter table, only
client PCs where the IP address is included in the range listed of the filter table will be
able to connect to the PDS series module. Any requests from other PCs will be rejected
Set IP1 only: only clients who’s IP address is included in the filter table are able to
connect to the PDS series module.
Set IP1 + IP2: set a range of IP address as a starting and ending point. The setting
allows clients who’s IP address is included in the range are able to connect to the PDS
series module.
Set IP1+Mask: set the IP filter range as:
(IP1 & Mask) + 0 ~ (IP1 & Mask) + (~Mask).
Only clients who’s IP address is included in the range are able to connect to the PDS
series module. For instance:
IP1 = 10.0.9.5, mask = 255.255.255.0
IP1 & MASK = 10.0.9.0, ~mask = 0.0.0.255
This allows clients who’s IP address is included in the range of 10.0.9.0 ~ 10.0.9.255
are able to connect to the PDS series module.

new settings will be valid immediately.
Port: The COM Port number on the PDS series module.
Baud Rate, Data Bits, Parity
Stops Bits, End Character:
The configuration settings should match the serial device used.
Fifo Trig. Level: FIFO trigger level
This option is used to set the number of characters that the COM Port can receive at
once time, the PDS will move the data from the COM Port FIFO to the PDS. If the amount
of data transferred is large and uses a transfer speed (115200 bps), setting a smaller value
is helpful in preventing data loss.
DBDT (ms): Data buffer delay timeout
When the COM port does not receive data from devices connected over the period of
DBDT setting, the PDS will determine that the data transfer is over and return to process
next tasks.
