4.9.2 Network Address
Default = 1
Network address allows user to assign a unique network address to an actuator.
1. The network address must be entered in accordance with the Instrument Data Sheet, and care must be taken to
ensure that the same address is not used anywhere else in the same network.
2. Select “NO” for small incremental changes or hold it continuously in that position for larger changes until the
required value is displayed. The address may be set at any value between 001 and 250.
4.9.3 Protocol
Default = Modbus RTU 9600 Baud
Protocol changes the communication language/speed from the default to match the application.
To Change from the Default Language:
Select “NO” to choose between MODBUS, ASCII, or RTU, and the baud rate depending on the design of the DDC
system. Refer to the contract documentation.
4.9.4 Analog Scale
Default = 0-100
Analog scale allows the user to change the scaling of the analog input from the default.
To Change from the Default Range:
Select “NO” until the required scale is displayed. 0-255 and 0-4095 counts are available.
4.9.5 ESD Action
A network ESD function can be enabled after the ESD configuration has been established for the unit. This network ESD
can be selected to either ignore the command; Close, Open, Stop, or Position the actuator.
