All manuals and user guides at all-guides.com

The WiSER2400.IP and the WiSER2400.Plus are IEEE 802.11b compliant

devices with built-in serial interfaces. They are desi ned to allow non-

wirelessly enabled serial devices to be connected and fully inte rated into an

802.11 Network.

The WiSER2400 receives data from equipment with serial ports; converts the

serial data into 802.11 compliant TCP or UDP data packets and transmits

these packets wirelessly. Conversely, the WiSER can receive wireless

packets, which it unpacks and delivers byte-by-byte to the destination

equipment/device throu h a serial port.

The WiSER2400 requires no device driver and is operatin system

independent. They can be used with almost any type of equipment that uses a

serial port, includin (but not limited to) cash re isters, electronic whiteboards

and navi ational instruments. Administration of the WiSER2400 is done

throu h a Windows based administrative software pro ram. The

administration software can be used to confi ure the unit’s operatin

parameters, administrative and local network settin s. It can also be used to

monitor the unit’s communication link conditions.

Fi . 1 WiSER2400.IP

The WiSER2400.IP comes with an RS-232 interface and a built-in

2dBi antenna. It comes supplied with a 5V DC power adapter.

The WiSER2400.Plus provides the same functionalities as the

WiSER2400.IP. It has an RS-232 DB-9 connector as well as a mini-

Phoenix connector for RS-485/422 interfaces. It accepts 5V DC to

32V DC power supply that has to be provided for separately by the

user. Input power connection is made throu h the mini-Phoenix

connector. It also comes with a DIN rail mountin clip and plate

assembly.

Note: Throu hout this manual, the term WiSER2400 is used to

refer to both the WiSER2400.IP and the WiSER2400.Plus

2.1 Using the WiSER2400 in a Point-to-point Link

2.1.1 Using the WiSER2400 in a point-to-point link

Scheme 1

See Figure 5 (overleaf)

Connect the PC to an 802.11b/ access point, or use a PC with a

built-in 802.11b/ wireless LAN card.

Confi ure the WiSER2400 to match its serial parameters (baud rate,

parity bit, … etc.) with that of the serial device it is to be attached to.

Confi uration can be done by temporarily connectin the

WiSER2400, by a serial cable or wirelessly, to a PC runnin the

WiSER2400 administration software.

Confi ure the WiSER2400 to match up its TCP/UDP/IP settin s

(listenin port, destination IP address, … etc.) with that on the PC

side for a TCP/IP or UDP/IP connection.

Confi ure the WiSER2400 to operate in the proper wireless network

type: Infrastructure mode for linkin to an access point, or Ad-hoc

mode for linkin with a PC with a built-in wireless LAN card.

Attach the WiSER2400 to the serial device.

Establish the wireless link between the PC and the WiSER2400.

The system is now ready for runnin the application software on the

PC to control the serial device throu h the wireless link.

If the application software on the PC can only communicate throu h

a serial COM port interface and does not support the standard

TCP/UDP/IP protocols throu h the network interface, the COM port

re-directin software pro ram, VirCOM, will be needed to brid e the

application software to the TCP/UDP/IP network port.

Please refer to Section 3 of this manual as well as the VirCOM

Technical Manual for details on confi urin the WiSER2400 and the

Virtual COM port re-directin software.
