LED Indication

The following table details the status of the indicating LEDs on the front panel under normal operating conditions.

LED Indicator	Condition	Meaning
OK	GREEN	Normal Operation
OK	Flashing RED/GREEN	Module Boot Sequence
Radio RX	GREEN flash	Radio receiving data (Good Signal Strength)
Radio RX	RED flash	Radio receiving data (Low Signal strength)
TX/LINK	GREEN	Radio Connection Established
TX/LINK	RED Flash	Radio Transmitting
RS-232	GREEN flash	Data sent from RS-232 Serial Port
RS-232	RED flash	Data received to RS-232 Serial Port
LAN	ON	Link Established on Ethernet port
LAN	Flash	Activity on Ethernet port.
RS-485	GREEN flash	Data sent from RS-485 Serial Port
RS-485	RED flash	Data received to RS-485 Serial Port
DIO	GREEN	Digital Input is grounded.
DIO	RED	Digital Output is active
DIO	Off	Digital Output OFF and Input is open circuit.

The Ethernet RJ45 port incorporates two indication LEDs. The LINK LED comes on when there is a connection on the Ethernet port, and will blink off briefly when activity is detected on the Ethernet Port. The 100MB LED indicates that the connection is at 100 MBit/Sec. The 100MB LED will be off for 10MB/Sec connection.

Other conditions indicating a fault are described in Chapter Four - DIAGNOSTICS.

3.2 Selecting a Channel

802.11 (900 MHz) Channels

The BU-945U-E conforms to the IEEE 802.11 Wireless LAN specification and supports various channels depending on regulations within the country of use.

If operating in the US, Canada, the frequency range is 902 to 928MHz and the available channels are:

•9 x non overlapping 1.25MHz channels

•9 x partially overlapping 2.5MHz channels

•4 x non overlapping 5MHz channels

•4 x overlapping 10MHz channels

•2 x overlapping 20MHz channels.

If operating in Australia the frequency range is 915-928MHz and the available channels are:

•4 x non overlapping 1.25MHz channels

•4 x partially overlapping 2.5MHz channels

•3 x overlapping 5MHz channels

•1 x 10MHz channel
