4 ArmorPoint EtherNet/IP Adapter, Series A
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 adapter to a specific 
I/O module may not always receive a response from the I/O module. 
In the case where the I/O module does not reply to the request, the 
adapter responds with an error code indicating a time-out.
ATTENTION
Preventing Electrostatic Discharge
This equipment is sensitive to electrostatic discharge, 
which can cause internal damage and affect normal 
operation. Follow these guidelines when you handle 
this equipment:
• Touch a grounded object to discharge potential
static.
• Wear an approved grounding wriststrap.
• Do not touch connectors or pins on component 
boards.
• Do not touch circuit components inside the
equipment.
• If available, use a static-safe workstation.
• When not in use, store the equipment in 
appropriate static-safe packaging.
