Introduction
Product Overview
The DeviceMaster AIR 1-Port is a one-port wireless serial device server that can
be panel or DIN rail mounted. The DeviceMaster AIR utilizes the 802.11b protocol
for the Ethernet connection, a DB9 male serial port, and is housed in a stainless
steel enclosure. It supports RS-232, RS-422, and RS-485 serial communication
modes. The product includes an external 100VAC power supply.
Note: The IAD DeviceMaster AIR 1-Port is shipped with an external 100/240VAC
power supply with both US and European style power cords.
You must use a web browser to initially configure the wireless settings for the
DeviceMaster AIR. See
Connecting the Hardware and Initial Configuration on
Page 9 for web browser requirements.
The DeviceMaster AIR supports Ad Hoc or Infrastructure mode.
Ad Hoc mode simply refers to peer-to-peer wireless networking. Ad Hoc does
not require an access point or wireless router. Wireless devices instead
communicate directly to each other in Ad Hoc mode. A basic Ad Hoc setup
could consist of a DeviceMaster AIR and a PC with a wireless NIC. A more
complex example would be to remove the access point and LAN Ethernet
segment from the Infrastructure example on the next page.
Infrastructure mode requires a wireless access point (AP) or wireless router
and is the most commonly used wireless configuration. In infrastructure mode,
wireless devices can communicate with each other or can communicate with a
wired network. The following drawing is an example of using the
DeviceMaster AIR in Infrastructure mode.
A longer Ethernet cable is required
during WLAN configuration.
