2.7 Configuring External Sensors
The E-BAM must have a 597A sensor connected and properly configured for operation. If the 597A
is not present, the E-BAM will not begin sampling. See section 8.1 for more details about available
wind sensors.
2.7.1 Configuring the 597A Sensor
The E-BAM requires a 597A sensor at address 1 of its serial network to begin sampling. Once the
physical connections are made the sensor is programmed using the Digital Link screen located in
the Test menu (see section 3.5.11).
Upon entering the Digital Link screen, any digital sensor
connected to the E-BAM with address 1 or 2 programmed
in it will appear in either the Sensor 1 or Sensor 2 fields, as
appropriate. In addition to the sensor type, the address
fields on this screen also display the firmware currently
installed in the sensor.
Figure 2-11 shows a typical configuration.
Figure 2-11 The Digital Link Screen
The State field indicates that the E-BAM is either starting up digital communications or waiting for a
response from the sensor. If either the sensor type or firmware revision is missing or incorrect,
communications are not properly established with the sensor. The grey SETUP button in the lower
left corner provides access to the Digital Setup screen for configuring the addresses of the digital
sensors. See section 2.7.2 for details.
2.7.2 Changing Sensor Addresses
The default address for most Met One Instruments, Inc. digital sensors is 1.
If a connected sensor has an address other than 1 or 2, it
can be located in the Digital Setup screen by pressing the
grey SCAN button in the bottom left corner (see Figure
2-12). The E-BAM will scan through all potential network
address nodes to locate any connected devices. Progress
of this scan can be seen in the third address field label
(which displays Addr 3, by default) and the word
“Scanning” will appear in the field itself.
Figure 2-12 Scanning for Sensors
If a device is located at some other address, it can be
changed by pressing the grey CHANGE button next to the
third address field. In the example shown in Figure 2-13,
the 597A has been configured for address 2. Pressing the
grey SET 1 button will update the address in the sensor to
address number 1 and exit back to the main Digital Link
screen. The Sensor 1 field will now display the 597A
details like Figure 2-11.
Figure 2-13 Change the Address
If two sensors share the same address, disconnect one of them and then use the CHANGE button
to set the other one to a different address. Remember that the 597A must be configured for address
number 1 and if an optional wind sensor is connected, it will need to be set to number 2.
