Cooper Bussmann BU-905U-L Wireless I/O Configuration Manual

6. To view additional information about a message, select the message line with the mouse. BU-Config shows additional information about the

message at the bottom of the screen including the system address, RSSI and CRC (i.e., error-check) status.

The “text box” in the bottom middle of the screen decodes the message to display the I/O channel and value.

NOTE: To completely decode the message, you must open the same configuration project corresponding to the

system being monitored.

You can also display the register values as:

• Decimal – by selecting Dec.

• Digital – by selecting Dig. BU-Config displays the value as a 0 or 1 digital value

(1 if the 16-bit value is greater than 50% - i.e., the most significant bit is 1).

• Analog – by selecting Anlg. BU-Config displays the value as a 4-20mA range.

NOTE: To stop decoding “comms logging”, click Stop Comms.

Other options allow data to be logged to a file, so that the data can be reviewed at a later time (Open Log File).

NOTE: Debug I/O is not used on the BU-905U-L modules.

Checking Input Statuses on a BU-905U-L-T

To check the status of inputs on a BU-905U-L-T:

1. Navigate to the Unit page for the unit you want to check.

2. Click Read Inputs.

3. BU-Config shows a page indicating the status of all inputs to the module:

4. Click Update to read the status of the inputs from the module.

5. For analog values (i.e.,. 4-20mA analog, Thermocouple, Temperature and Battery Voltage), you can select the units for displaying the data:

• Raw – shows the value as a decimal number;

• Hex – shows the value as a hexadecimal number, both in the internal representation of the module;

• mA – displays the number of milliamps that would be output if the data was sent to an Analog output on a Cooper Bussmann

BU-905U-L-R module; and

• % – displays the percentage of the nominal full scale range.

For more information on translating between different analog signal types, Appendix A – Tables for translating different

analog signal types on page 75.
