Changing Card Settings 
The communication cards are factory installed with default settings. You may want to 
adjust individual card settings to work with your specific system set up. The 
communication cards are hot swappable -- this means you do not have to power down 
the D400 unit to remove and install the communication cards. 
» 
To change the settings on a communication card: 
1. 
At the rear panel of the D400, using a flathead or Phillips screwdriver loosen (but 
don’t completely remove) the two screws from the top and bottom of the 
communication card. 
2. 
Using the flathead screwdriver, gently pry the top of the card from the slot and 
remove it from the chassis. 
3. 
Refer to the instructions in the following sections to make any required changes to 
the switch settings on the card.  
Tip:  Use a small flathead screwdriver (same as used to remove the communication 
card screws) to change switch positions. 
4. 
Slide the card into the same slot you removed it from, and tighten the two screws. 
CAUTION:  For proper transient protection, the recommended tool torque settings for 
communication card screws are 2.6 in-lb [0.294 Nm].
