What is the 1734-ADN(X) Adapter? 2-3
Set Subnet/Backplane Baudrate
The adapter and Subnet modules must use the same baudrate to
communicate with each other. Use one or both of the following to set
a Subnet baudrate.
• Enable or disable the Backplane Autobaud feature for POINT
I/O modules. POINT I/O modules have Autobaud enabled as
the default- See page
2-12.
• Set the adapter baudrate for the Subnet. The default for the
1734-ADN is 1Mbaud. The default for the 1734-ADNX is
125Kbaud - See page
2-9.
Set Subnet I/O Module Addresses
Once the adapter and POINT I/O modules are communicating at the
same rate on the backplane, you must make sure all modules use a
valid MAC ID.
Set the Auto Address feature for POINT I/O modules - See
page 2-13.
IMPORTANT
You set the backplane baudrate for the 1734-ADN.
You set the Subnet baudrate for the 1734-ADNX.
