6 Zone Control I/O Cards
Publication 1799-IN007D-EN-P - October 2005
Each card is shipped with the node address set to 63 in the card’s memory. The rotary
switches are set for position 99 at shipment. The switches are located near the center of the
card. The two switches are:
• MSD (most significant digit)
• LSD (least significant digit)
To reset the node address, use a small blade screwdriver to rotate the switches. Line up the
small arrow on the switch with the number setting you wish to use.
The rotary switches are read only when you apply power to the card. Settings between 64 and
99 cause the card to use the last valid node address stored in the card’s memory.
For example, the last setting in memory is 40. If a change is made to 68, and then you apply
power to the card, the address will default to 40.
The card is equipped with AutoBaud detect. AutoBaud lets the card detect the
communication rate on your DeviceNet network and automatically adjusts to that rate.
The card is shipped with AutoBaud enabled.
