Configuration
Getting Started
The four configurable BACnet Device Object properties have two sets of “default” settings, the factory setting
and the configuration mode setting and are identified in the following table:
property
factory value
configuration mode value
Device_Instance 153000*
153000*
Object_Name “NEPSKGHumidifier153000” “NEPSKGHumidifier153000”
Max_Master 127
127
MSTP_MACaddress 0
254
* Note: These values are NEP’s BACnet Vendor_Identifier*1000.
Prior to the first time the NEPICSKG is powered on, you’ll have to know two things:
What’s the baud rate of the MS/TP network?
Is there already an MS/TP unit on that network with the MAC address=0 and the Device Instance=153000?
Once the answer to Question 1 is known, the dip switches 2 and 3 must be set up accordingly.
If the answer to Question 2 is no (there is no MS/TP MAC address 0), then you can start up the NEPICSKG with
the dip switch 1 in the OFF (operational) position. In this mode, the factory settings are in effect and the
NEPICSKG will be MS/TP token-passing master with a MAC address=0 and Device Instance=153000.
If the answer to Question 2 is yes (there already is an MS/TP MAC address 0 and/or there already is a Device
Instance 153000), then you will need to start up the NEPICSKG with the dip switch 1 in the ON (configuration)
position. In this mode, the configuration mode settings are in effect and the NEPICSKG will be MS/TP non-
token-passing slave with a MAC address 254.
Configuring in the Operational Mode
The NEPICSKG can be configured from a BACnet client device using the BACnet WriteProperty service at any
time, while in the operational mode. In other words, the Device_Instance, Object_Name, Max_Master and
MSTP_MACaddress
can be changed “hot” with the changes taking effect immediately and without having to
restart the NEPICSKG.
