2.2 Understanding ADAM-4570W & ADAM-4571W
ADAM-4570W and ADAM-4571W are advanced data gateway units.
They extend traditional COM ports of a PC by giving them access to an
802.11b WLAN network. Since ADAM-4570W and ADAM-4571W are
connected through an 802.11b WLAN network, you will need to know
some basic facts about networking in order to get the server hooked up
correctly.
2.2.1 Network Architecture
Traditional serial port communication uses a COM port board that slides
into one of the slots at the back of your PC. In this case, only the com-
puter containing the board can access the
serial port. With ADAM-4570W or ADAM-4571W, you are now able to
access the COM port from a distance through a local area network and
WLAN. ADAM-4570W and ADAM-4571W can be integrated within the
network architecture of any protocol.
Note, all serial devices which are connected to the same port must have
the same protocol running, and the same transmission speed. Connect
devices with different protocols to different ports of ADAM-4570W or
ADAM-4571W.
