Hardware Specifications and Compliance Notices
The DeviceMaster AIR has four
connectors on the back of the unit:
• LAN: this RJ45 auto-sensing MDI/
MIDX port provides connection to a
network device using a Category 5
Ethernet cable. The auto-sensing MDI/
MIDX port can use either a straight-
through or cross-over cable.
Comtrol provides an Ethernet jumper
cable that is connected between the
LAN and WLAN connectors to support
one serial port.
If you use the DeviceMaster AIR as a bridge, you will not have any cables
connected to the LAN connector.
• WLAN: this RJ45 auto-sensing MDI/MIDX port provides connection to a
network device using a Category 5 Ethernet cable. The auto-sensing MDI/
MIDX port can use either a straight-through or cross-over cable.
Note: Category 5 is the most reliable grade of twisted pair cable. Always check
to make sure that you have selected the correct type of cable for your
other devices on the network.
An Ethernet cable is connected between the WLAN connector and the same
network segment as a PC during initial installation to configure the wireless
settings. The default IP address for the WLAN port is 192.168.0.30.
After configuration, you will need to reconnect the Ethernet jumper cable
between the LAN and WLAN connectors to use the DeviceMaster AIR as a 1-
port serial device. To use the DeviceMaster AIR as a bridge, connect an
Ethernet cable between the WLAN port and an Ethernet port of another
device, such as a DeviceMaster RTS 8 to create eight wireless serial ports.
• Reset Button: press this internal button for a few moments to revert to the
factory default settings of the DeviceMaster AIR. See
for the WLAN Port
• Power Receptor: connect one end of the 5 VDC power adapter (included) to the
power receptor on the DeviceMaster AIR and connect the other end of the
power adapter to a power outlet.
