Table 2 shows the different possibilities with the Status LED behaviour of the BACnet module.
Condition of the Status LED Possible Cause Solution
 2 short blink (no wires
connected to the module)
Controller is searching for an MS-
TP BACnet network. Either at
selected Baud rate or is currently
Auto-Bauding
Connect Controller to
Network
 2 short blink (wires
connected to the module)
Module is not at the same baud
rate as the network or set at a
different Baud rate than Main
network
If Auto-Bauding, power off
and on the controller.
If wrong Baud rate is
selected, match network
Baud rate for each device.
 2 short blinks and a longer
blink (wires connected to
the module)
The module has detected the
presence of a network and is in the
Token Pass of the ring
N/A
Table 2: Status LED condition and possible solutions
Default Device Name and default Device ID
Default Device Name is set to: Model number
– MAC:
 Where MAC is the current MAC address of the device.
 Where Model number is Viconics part number.
The device name will be upgraded as soon as there is a change to the device MAC address.
 Default Device ID is set to: 76000 + MAC
 Where MAC is the current MAC address of the device.
The device ID will also be upgraded as soon as there is a change to the device’s MAC.
For an RTU controller example, when a VZ76561000B controller with a MAC address of 63 is connected to a
network, its default Device Name will be VZ76561000B-63 and its default Device ID will be 76063.
For a zone controller example, when a VZ7260F5x00B controller with a MAC address of 12 is connected to a
network, its default Device Name will be VZ7260F5x00B-12 and its default Device ID will be 72012.
Device Name and Device ID properties are writable in Viconics’ device object. Both properties can be renamed
from any BACnet network management tool as long as the tool itself can write to these properties.
