Table 2 shows the different possibilities with the Status LED behaviour of the BACnet module.
Condition of the Status LED Possible Cause Solution
¾ 1 short blink
BACnet communication NOT active
at default MAC address = 254 Change MAC address to
another value from 0 to 127
A T7600 BACnet module has been
installed on a VT7600 controller Install a VT7600 BACnet
module on the controller
A VT7600 module has been
installed on a T7600 controller Install the BACnet module on
a VT7600 controller model
¾ 2 short blink (no wires
connected to the module)
The right module has been installed
on the right controller model
N/A
¾ 2 short blink (wires
connected to the module)
Module is not at the same baud
rate as the network Power off and on the
controller
¾ 2 short blinks and a longer
blink (wires connected to
the module)
The module has detected the
presence of a network

Table 2: Status LED condition and possible solutions
Default Device Name and default Device ID
Default Device Name is set to: Model number – MAC:
¾ Where MAC is the current MAC address of the device.
¾ 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.
¾ Default Device ID is set to: 76000 + MAC
¾ 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 example, when a VT7600B5x00B controller with a MAC address of 63 is connected to a network, its default
Device Name will be VT7600B5x00B-63 and its default Device ID will be 76063.
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.
