Manual Mac Addressing - Honeywell ComfortPoint Open CPO-VAV2A Installation Instructions Manual

address required. By default, the switches are already set to
(0xFF) for controllers that support Automatic MAC addressing.
To enable Automatic MAC addressing again, set the switches
back to (0xFF).
For the controller to support AutoMAC, the boot loader version
must be v2.5.1 or later and the firmware version v2.7.3 or
later.
Attention
The switches are only read by the controller when
turned ON. Therefore, whenever the switch
positions are changed the power must be
removed and reapplied before the new switch
positions take effect.
Possible Automatic MAC addressing scenarios
Note
The times provided in the following table are only
for information. The actual time taken for
resolution of MAC address conflicts may slightly
vary.
Scenario
A: Auto MAC controller
initial start-up time and
acquire MAC address on
single BACnet MS/TP
bus after power-on (Cold
boot or reset).
B: Average initial start-up
time and acquire MAC
address where all
controllers on a single
MS/TP bus are Auto
MAC controllers.
Time Remarks
30 secs 29 Manual MAC controllers.
1 Auto MAC controller that
must acquire a MAC
address.
Time includes start-up time
plus time to acquire MAC
address.
260 secs 30 Auto MAC controllers.
All controllers must acquire
a MAC address.
Time includes start-up time
plus time to acquire MAC
address.
Scenario
C: Average time for MAC
conflicts to be resolved
when an Auto Mac
controller is added to an
MS/TP bus while Auto
MAC process is still
operating.
D: Average time for MAC
conflicts to be resolved
when a Manual Mac
controller is added to an
MS/TP bus while Auto
MAC process is still
operating.
E: Average time for MAC
conflicts to be resolved
when a manual MAC
controller with conflicting
MAC address is added to
an MS/TP bus.
F: Average time for Auto
MAC controller restart
where all controllers on
MS/TP bus are Auto Mac
and have previously
acquired a MAC address.
Verify that the MAC
address remains
unchanged after restart
when there is no conflicts.

Manual MAC addressing

Attention
Address Switch 1 & Address Switch 2 are HEX
switches which are used in combination for
addressing the CPO-VAV2A controller. The valid
address for CPO-VAV2A is from 1 to 30.
