PDS-8x1 Series User Manual, Version 1.1.2, Apr. 2015 - 6 -
1. Introduction
The PDS-811 and PDS-821 programmable device servers (PDS) are compact, modular, intelligent,
rugged, and are designed for networking RS-232 and RS-422/485 serial devices to an Ethernet
network. The PDS-811 has one I/O expansion slot, while PDS-821 has two I/O expansion slots that
can be used to attach various 2- or 4-port serial communication modules. Therefore, a maximum of
4 serial ports can be installed on the PDS-811 or a maximum of 8 serial ports can be installed on the
PDS-821.
Note: There is no serial module built-in to the PDS-811 or PDS-821 by default.
The PDS-811 and PDS-821 controllers are equipped with a 2-port 10/100 Base-TX Ethernet Switch
that can be used to connect two network segments. The Ethernet Switch processes and routes data
on the data-link layer (layer 2) of the OSI model to create a different collision domain per switch
port. Using a switch allows you to attain dedicated bandwidth on point-to-point connections with
every computer, and therefore run in full duplex mode with no collisions. Furthermore, the built-in
2-port Ethernet Switch on the PDS-811/821 enables network wiring to be simplified by cascading
your Ethernet devices.
The PDS-8x1 series contains a built-in operating system, the MiniOS7, which offers a stable and high
performance environment that is similar to DOS. The MiniOS7 can boot up the PDS-8x1 series
within just one second, with the added benefit of no virus problems and a small footprint.
Furthermore, the PDS-8x1 series is designed for low power consumption, maintenance elimination
(no hard disk and no fan), and is constructed from fire retardant materials (UL94-V0 level) with a
robust case.

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and is now outdated.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-8x1
controller 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.

Programmable Device Server with I/O Expansion Slot(s)
PDS-8x1 Series User Manual, Version 1.1.2, Apr. 2015 - 10 -
The VxComm driver controls all the details of the Ethernet TCP/IP programming technique,
meaning that, with the assistance of PDS-8x1 controller 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-8x1 controller 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-8x1 controller via an Ethernet network without needing to install any
other software tools, thereby reducing the learning curve required for maintaining the device.

Run Mode: Firmware operation mode
For PDS-8x1 controller, the operating mode switch is set to the Run position by default. In
order to update the firmware for the PDS-8x1 controller, the switch must be moved from the
Run position to the Init position. The switch must be returned to the Run position after the
update is complete.
