DEVICE CONFIGURATION THROUGH BACnet
DEVICE INSTANCE
The Device Instance, by default, is 1035000 plus the Address. For example, an Address of 21 results in a default address
of 1035021. This can be changed once the device is connected to the network, but each device instance must be unique
within the network. The device instance must be unique throughout the entire BACnet network, not just this segment.
DEVICE LOCATION
The device location is optional but is intended to allow for further definition of the device’s location. The device location can
be a character string up to 64 characters in length.
DEVICE NAME
By default, the device name is based on the type of device and the address. The device name can be a character string up to
(32) characters in length. This can be changed once the device is connected to the network. For example: Temperature
Sensor - 034. The device name must be unique throughout the entire BACnet network, not just this segment.
DEVICE DESCRIPTION
By default, the device name is based on the type of device and the address. The
device name can be a character string up to (32) characters in length. This can be
changed once the device is connected to the network. For example: Temperature
Sensor - 034. The device name must be unique throughout the entire BACnet
network, not just this segment.
LED INFORMATION
One LED indicates three statuses. Solid green shows that power is good, but no data is transmitting. A solid Amber indicates that
auto-baud is set and no data has been received to set a baud rate. Green/Amber flashing indicates data is being transmitted or
received. Solid Red LED status indicates an error state, usually loss of communication on the network. If this status remains for
(10) times the APDU timeout, the device will automatically reset. If this state remains longer than that, reset the device.
TEMPERATURE CONFIGURATION
One LED indicates three statuses. Solid green shows that power is good, but no data is transmitting. A solid Amber indicates that
auto-baud is set and no data has been received to set a baud rate. Green/Amber flashing indicates data is being transmitted or
received. Solid Red LED status indicates an error state, usually loss of communication on the network. If this status remains for
(10) times the APDU timeout, the device will automatically reset. If this state remains longer than that, reset the device.
TEMPERATURE AND RH OFFSET
This device allows for a temperature offset of +/-5
°C
(9
°F
) and an RH offset of +/-10%. By default, these values are set to 0,
meaning no offset is added. These are set by writing to the present value of the Temperature Calibration Offset (AV0) or RH
Calibration Offset (AV1). The value written must be within the specified range or an error will be returned. To set these back
to factory settings, write any changed values to (0).
TEST MODE
For the Sensor objects (AI0 and AI1), a test mode can be set by writing the Boolean value true to the “out-of-service”
property. Then the present-value can be set to any valid test value the user requires. This allows a user to test reactions to
specific values returned by this device.
RESET
The reset button can be used to reset the device without disconnecting power. The location of this button is shown in
FIGURE 3
(p. 2).
