2-Port Wireless Device Servers with Wi-Fi
|
|
The 2-port
Wireless Device Servers have competitive edge features such as
flexible operation mode, TCP/UDP multicasting,
telnet COM port control
protocol support (RFC2217 compliant), SSL encryption,
Surge
Protection, and port event
handling for wireless device networking. Wireless-enable any serial device or add embedded 802.11x LAN networking
to electronic devices using "Wireless Device Solutions"
products. Wireless Device Servers provide a whole new level of flexibility and mobility. You can
connect devices that are inaccessible via cabling. And you can add
intelligence to your business by putting mobile devices, such as medical
instruments or warehouse equipment, on the network.
Application Areas:
The PS110W is designed for large-scale wireless installations
especially in the areas of retail/pos, industrial, medical, and banking
sectors, which are traditionally fitted with serial connections. It can
be used in a wide range of retail/POS applications including wireless
payment and receipt printers.

Device Servers help maximize IT asset productivity while providing
scalability and reducing operational costs. There are a variety of ways that "Wireless Device Servers" from "Wireless Device Solutions"
can be implemented; the two most fundamental options derive from the
802.11 specification itself.
Modes of Operation > Infrastructure Mode Connection
When working in infrastructure mode, the
Wireless Device Server transmits serial device data to the host PC via an access point.
Modes of Operation > Ad-hoc Mode Connection
Benefits of using Wireless Device Servers from "Wireless Device Solutions":
There are three core benefits to integrating a
Wireless Device Server into an automation
or control system.
(1) First, Wireless can reduce cabling costs. This is especially
relevant in hard-to-cable or hazardous areas, listed buildings or where
temporary installations (concerts/conferences, etc.) are required.
(2) Secondly Wireless means increased mobility. Forklift trucks,
instrument trolleys and cranes are just a few of the devices that need
freedom of movement and where Wireless may save on the cost of armoured
cabling systems.
(3) Lastly, wireless technology delivers IP routing of data. The serial
data is routed using IP addressing which means the data can be forwarded
using a wired or wireless LAN,WAN or even the Internet.
Apart from the tangible savings, there is also an element of prestige
for anyone using leading-edge technology. Both system integrator and
end-user can benefit from marketing opportunities generated by use of
new wireless applications.
