Programmable Serial-to-Ethernet Device Server
1. Introduction
The PDS 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 series
into standard COM ports on a PC. By virtue of its protocol independence, a small-core OS and high
flexibility, the PDS series is able to meet the demands of every network-enabled application.
The PDS 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 up in just one second and gives you fastest responses.
The PPDS(M)-700, PPDS(M)-700-MTCP and PPDS-700-IP67 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(M)-700-MTCP and PDS-5105D-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.
The PPDS-700-IP67 is a special design for the toughest applications. It can be directly mounted to
any machine or convenient flat surface. The rugged packaging and IP67 connectors are rated to
protect against water, oil, dust, vibration, and much more.

1.2 Ethernet Solutions
Nowadays, the Ethernet protocol has become the foremost standard for local area networks.
Connectivity via the Internet is now common in many of the latest applications 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 machines from multiple vendors, and also provides a cost-effective solution
for industrial control networks.

1.3 VxComm Technology
In general, writing a TCP/IP program is more difficult than writing a COM Port program. Another
issue is that perhaps the existing the COM Port communication system was built many years ago
and is now outdated.
As a result, a new technology, VxComm was developed to virtualize the COM Ports of the PDS
series to allow up to 256 COM Ports to be used on a 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, Version 2.5, Mar. 2019 - 13 -
Page 14
Programmable Serial-to-Ethernet Device Server
The VxComm driver controls all the details of the Ethernet TCP/IP programming technique,
meaning that, with the assistance of PDS series and VxComm technology, your COM Port program
will be able to access your serial devices through the Ethernet in the same way as through a COM
Port.

1.4 Web Server Technology
Web server technology enables the PDS series to be configured via a standard web browser
interface, e.g. Google Chrome, Internet Explorer, or Firefox, etc. This means that it is easy to check
the configuration of the PDS series via an Ethernet network without needing to install any other
software tools, thereby reducing the learning curve required for maintaining the device.

Step 3: Check the 5-digit 7-SEG LED. Data will be shown as follows:
Note: Only D-version modules have a 5-digit 7-SEG LED.
Information related to the PDS series module can be classified into 4 main
areas:
Group ID 11111: The IP address information for the PDS series
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
PDS Series User Manual, Version 2.5, Mar. 2019 - 53 -
Page 54
Programmable Serial-to-Ethernet Device Server
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.
PDS Series User Manual, Version 2.5, Mar. 2019 - 54 -
Page 55
Programmable Serial-to-Ethernet Device Server
The format for the COM Port Data Format 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 or
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 and 5 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-700 has been reset, e.g. 20002
(The PDS 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.
PDS Series User Manual, Version 2.5, Mar. 2019 - 55 -
Page 56
Programmable Serial-to-Ethernet Device Server
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.
Module Name: dS.7xx
If the 5-digit LEDs do not display the above detail, take the following steps:
1. Power off the module
2. Connect the INIT* pin to the Vs+ pin
3. Power on the module and double check the configuration
Step 5: Power off the module.

4.2.1 Set IP Filter
The Set IP Filter limits which client PCs are able to link to the PDS series 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. Any requests
from other PCs will be rejected.

4.3.1 Operation Mode: M0, M1, M2 and M3
M0: Transparent Mode (Multi-echo, shared)
M0 is used for Virtual COM and TCP/IP connections. In this mode, data is transmitted to each client
that is connected to the PDS series module.
Condition 1: One client sends a request to the PDS series to access a device. The PDS series
transmits the data from device to each connected client.
Condition 2: No clients send any requests to the PDS series. The PDS series transmits data from the
device to each connected client.

M1: Slave Mode (Single-echo, Non-shared)
M1 is used for Virtual COM and TCP/IP connections. In this mode, data is transmitted to the specific
client that requested the service. If the client does not send a request to the COM port of the PDS
series module, then the module won't return any data to it.
Condition 1: One client sends a request to the PDS series to access a device. The PDS series
transmits data from the device to the client that requested the service.
Condition 2: No clients send any requests to the PDS series. The PDS series doesn’t transmit any
data from the device to any client.

M2: Half-Slave Mode (Is situated between M0 and the M1 mode)
M2 is used for Virtual COM and TCP/IP connections. If only one client connects to the PDS series,
the operation mode same as M0 mode (Multi-echo, shared), refer to Section “M0: Transparent
Mode”. If there are two or more clients connecting to the PDS series, the operation mode same as
M1 mode (Single-echo, Non-shared), refer to Section “M1: Slave Mode”. PDS sends data to the last
client when data is available but no request from any client.
M3: Modbus Gateway
When PDS series are configured to Modbus Gateway, the operation mode will be automatically set
to M3 mode. The more detailed information regarding configuring Modbus Gateway, refer to
Section 4.4 “Modbus Gateway Settings” and Chatper 5 “Modbus Testing and Protocol”.
