Expand legacy I/O ports over Ethernet connection
The growth and advances of small form factor PC continues to meet challenges and open
up new opportunities. SUNIX DevicePort® products are specifically developed to meet
such requirements and to replace current add-on card solutions. Users can expand legacy
I/O ports over Ethernet connection that improves solution deployment efficiency to achieve
greater reliability in commercial and industrial automation applications.
DevicePort® Advanced Mode supports both Direct-Link and Ethernet-Link connections
Cascading Ethernet Ports Make Wiring Easy
SUNIX DevicePort® has two 10/100 Ethernet ports built-in that can act as Ethernet switch
for easy setup. One port connects directly to the network or server, and the other port can
be connected to another Ethernet device or other DevicePort® via Daisy Chain mode. This
will prevent complicated cabling setup, and reduce overall investment cost on networking
equipment, such as switches.
DevicePort® Daisy Chain Topology

SUNIX DevicePort® proprietary Ethernet I/O Redirection Technology
With Ethernet hot-plug and system auto-detect capability, user can expand RS-232 COM
and Printer LPT port easily without complex software configuration. Just simply plug in the
RJ45 Ethernet cable between SUNIX DevicePort® and PC Host, the computer system will
create physical COM/LPT ports automatically with real time data transmit and receive
communication. User can easily access the port by using existing software application, and
TCP socket protocol re-compiling are not necessary.
DevicePort® supports physical COM port mapping over Ethernet connection

10
Smart COM Off-Line Deployment
SUNIX DevicePort® Advanced mode supports off-line mapping feature that able to keep
hardware COM port resources within the system device manager even when DevicePort®
being disconnected from the network. There are two major benefits on this Off-Line feature:
Ethernet Hot-Plug and Plug-n-Play capability – SUNIX DevicePort® will create or remove
physical COM/LPT ports automatically from the system resources. However, most
application software does not allow hardware COM/LPT to drop when specific ports are
opened. Under certain harsh network environment scenario, to prevent application software
to crash, DevicePort® off-line mapping feature will keep hardware COM/LPT port address
within the system device manager when DevicePort® being disconnected from the network.
After DevicePort® is re-connected back to the network, data communications will recover
back to the same resources automatically.
Secondly, DevicePort® off-line mapping feature can also use to deploy to the system
architecture design. System administrator can setup and create COM/LPT port right at the
application software without physically making Ethernet connection to DevicePort®. SUNIX
will provide corresponding API function library which allows software developers to easily
develop their programs to manipulate any serial COM communication.
DevicePort® COM ports keep alive in the system without DevicePort® connecting

1.5 Product Applications
DevicePort® on Data Acquisition
With SUNIX DevicePort® Ethernet I/O Redirection Technology, traditional data collection which in
the form of waveforms, on/off signals, or temperature readings have been greatly improved by the
Ethernet networking feature. Ethernet allows systems to be more distributed, and remote monitoring
is also possible. Here is the innovated example for centralized data acquisition solution;
A controller must be used (generally a PC or PLC) to connect to sensors and the SCADA/HMI
system under traditional data acquisition infrastructure
Traditional Solution
With SUNIX DevicePort®, data acquisition infrastructure changes from a centralized and localized
system to a distributed and remotely monitored system. It also saves huge among of initial
hardware investment and future maintenance cost.
SUNIX DevicePort® Solution
The best approach in deploying a distributed Ethernet-based data acquisition system is to create a
device link through daisy-chain topology that saves implementation costs such as switches, cable
wiring, as well as labor costs. SUNIX DevicePort® improves deployment efficient to achieve
greater reliability in commercial and industrial automation applications, such as factory automation,
security and surveillance systems.

DevicePort® on Mobile Tablet Computers
The Tablet computer market share is reaching its saturation point in the consumer market,
but for enterprise applications, it has just started to pick up steam; as in commercial
automation solution. Tablet computers can help to enhance employee productivity and
increase sales incentives for many small businesses and retail sales sectors. However,
most tablet computers lag with physical I/O connectivity; additional I/O docking stations are
needed to make those peripheral connections; this will eventually reducing tablet
computers mobility and conveniences.
With SUNIX DevicePort, Ethernet enabled Port Replicator, it’s easy to expand Legacy
RS-232 COM and Printer LPT ports wirelessly on tablet computers. By simply connecting
the RJ45 Ethernet cable between the SUNIX DevicePort® and WiFi Access-Point, the
tablet computers will create physical COM/LPT ports automatically with real time data
communication within the same network. User can easily access COM and LPT ports
remotely by using the existing software application without any need for physical cable
connection on your tablet computers.
DevicePort® Mobile I/O Redirection & Device Sharing Technology
In order to share Serial/Printer peripheral with multiple hosts (e.g. Desktop or Tablet PC).
With SUNIX DevicePort® Device Sharing feature, it enables DevicePort’s connected
peripheral to be shared by multiple hosts on the network. SUNIX will provide corresponding
application programming interface (API) and dynamic-link library (DLL) module which
enables software designers to easily develop their programs to manipulate any serial and
printing communication.
