Before You Begin
To effectively use your adapter, note the following considerations.
Determine Compatibility
If using the adapter with a 1756-ENBT module or 1788-ENBT module, use the following
required firmware versions for these bridge modules:
• 1756-ENBT firmware version 2.3 or greater
• 1788-ENBT firmware version 1.33 or greater
If you use the BootP Utility to assign IP addresses to the adapter, use version 2.3.2 or
greater.
Understand Messaging
Class 3 (Explicit Message) requests through the 1738-AENT adapter to a specific
ArmorPOINT I/O module do not always receive a response from the module. In the case
where an ArmorPOINT module does not reply to a request, the adapter responds with an
error code indicating a time-out.
Configure Autobaud
The adapter cannot reconfigure an I/O module that you previously configured to operate
at a fixed baud rate. When you reuse an ArmorPOINT I/O module from another
ArmorPOINT I/O system, configure the module to autobaud before using it with the
adapter.
