Connect the PC to an 802.11b/g access point, or use a PC with a
built-in 802.11b/g wireless LAN card.
Configure each WiSER2400 to match its serial parameters (baud
rate, parity bit, … etc.) with that of the serial device it is to be
attached to. Configuration can be done by temporarily connecting
the WiSER2400, by a serial cable or wirelessly, to a PC running
the WiSER2400 administration software.
Configure each WiSER2400 to match up its UDP/IP settings
(listening port, destination IP address, … etc.) with that on the PC
side for a UDP/IP connection. Configure the PC side to operate in
UDP broadcast mode. Enable each WiSER2400 to receive UDP
broadcasts.
Configure the WiSER2400s to operate in the proper wireless
network type: Infrastructure mode for linking to an access point,
or Ad-hoc mode for linking with a PC with a built-in wireless LAN
card.
Attach the WiSER2400s to the serial devices.
Establish the wireless link between the PC and the WiSER2400s.
The system is now ready for running the application software on
the PC to control the serial devices through the wireless link.
If the application software on the PC can only communicate
through a serial COM port interface and does not support the
standard TCP/UDP/IP protocols through the network interface, the
COM port re-directing software program, VirCOM, will be needed
to bridge 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 configuring the WiSER2400 and
the Virtual COM port re-directing software.
