Introduction
Purpose
SERCOS II and SERCOS III boards share the PCI bus with many other devices. Certain MS Windows operations, such
as reading a USB memory device, can take priority over SERCOS signals and cause a slight delay in SERCOS
communication. This delay can cause a drive fault or other cutting performance issues.
This Field Service Bulletin (FSB) describes the steps required to reposition the SERCOS II or SERCOS III master
boards in the EDGE Pro and MicroEDGE Pro CNCs as a first step in addressing these performance issues.
Tools and materials needed
#1 Phillips screwdriver
5/16-inch wrench or socket
1/4-inch wrench
Contents of kit 428305
WARNING!
ELECTRIC SHOCK CAN KILL
Disconnect electrical power before performing any maintenance.
Only qualified personnel can work inside the CNC cabinet with AC power
connected.
See the Safety section of the system’s manual for more safety precautions.
CAUTION!
Static electricity can damage circuit boards. Use proper precautions when handling
printed circuit boards.
Store PC boards in anti-static containers.
Wear a grounded wrist strap when handling PC boards.

Repositioning SERCOS II and SERCOS III boards in the EDGE Pro CNC
Location of boards in EDGE Pro PCI slots
As you follow this procedure, set aside all screws and other hardware for reuse.
To open the CNC enclosure:
1. To open the front panel, use a 5/16-inch wrench to remove the three screws at the top of the panel and the three
screws at the bottom of the panel.
2. To open the side, use a 5/16-inch wrench to remove the two screws at the top of the panel and the two screws at the
bottom of the panel.
To remove the SERCOS II or SERCOS III master board:
1. Remove the RX and TX cables from the outside edge of the board.
2. Use a #1 Phillips screwdriver to remove the screw in the mounting frame.
3. Pull the board from PCI slot 3 on the motherboard.
To reposition the utility and serial isolation board:
1. Remove the serial cables from the left side of the board:
a. Use a #1 Phillips screwdriver to remove the screws from either side of the serial cable connectors.
b. Remove the grey and multicolored ribbon cable connectors from the serial connectors on the left side of the
board.
c. Remove the screw that holds the silver board bracket to the side of the subchassis.
You do not need to remove any other cables from the connectors on the board.
2. Use a #1 Phillips screwdriver to remove the screw from the standoff at the right front of the board.

3. Pull the board from PCI slot 4 on the motherboard.
4. Insert the board connector into PCI slot 3 on the motherboard.
5. Use a 1/4-inch wrench to replace the standoff with the new standoff from the kit. Tighten the new standoff to 1.12
N·m (10 lb·in.).
6. Position the hole at the front of the board over the new standoff.
7. Fasten the screw through the board to the standoff and tighten it to 1.12 N·m (10 lb·in.).
8. Fasten the screw through the board bracket to the subchassis and tighten it to 1.12 N·m (10 lb·in.).
9. Plug the serial cables into the left side of the board:
a. Plug the grey ribbon cable into the Serial 2 connector.
b. Plug the multicolored ribbon cable into the Serial 1 connector.
10. Fasten the screws on either side of both serial cable connectors and tighten them to 0.67 N·m (6 lb·in.).
To replace the SERCOS II or SERCOS III board:
1. Insert the SERCOS II or SERCOS III board into PCI slot 4 on the motherboard.
2. Fasten the screw in the mounting frame and tighten it to 1.12 N·m (10 lb·in.).
3. Reconnect the RX and TX cables to the correct connector on the side of the board.

To replace the CNC enclosure:
1. Fasten the screws at the top and bottom of the front panel and tighten them to 3.39 N·m (30 lb·in.).
2. Fasten the screws at the top and bottom of the side panel and tighten them to 3.39 N·m (30 lb·in.).
After you reposition the boards
After a SERCOS II update, if you cannot establish the ring, verify that the RX and TX
fiber optic cables are securely plugged into the correct connector. LED 1, for the RX port,
should be illuminated in green. For more details, see the EDGE Pro SERCOS II
Instruction Manual (807640).
After a SERCOS III update, if you cannot establish the ring, verify that the SERCOS III
cables are securely plugged into the correct ports.

As you follow this procedure, set aside all screws and other hardware for reuse.
To remove the enclosure cover:
1. Use a #1 Phillips screwdriver to remove the 6 screws on the top of the panel.
2. Use a #1 Phillips screwdriver to remove the 2 screws on the side, at the bottom.
To remove the SERCOS II or SERCOS III master board:
1. Remove the RX and TX cables from the back of the CNC.
2. Use a #1 Phillips screwdriver to remove the screw that connects the PCI bracket at the side of the board to the
enclosure.
3. Pull the board from PCI slot 3 on the motherboard.
To reposition the wireless board:
1. Disconnect the antennas or antenna cables from the connectors on the back of the CNC.
2. Use a #1 Phillips screwdriver to remove the screw that connects the PCI bracket to the enclosure.
3. Pull the wireless board from PCI slot 2 on the motherboard.
4. Insert the PCB connector into PCI slot 3 on the motherboard.
5. Fasten the screw through the PCI bracket into the enclosure and tighten it to 1.12 N·m (10 lb·in.).
6. Connect the antennas or antenna cables to the back of the CNC.

Moving the wireless card may reset network passwords and IDs. If the controller does not
connect to the network, refer to the MicroEDGE Pro Instruction Manual for wireless setup
information.
After a SERCOS II update, if you cannot establish the ring, verify that the RX and TX fiber
optic cables are securely plugged into the correct connector. LED 1, for the RX port,
should be illuminated in green. For more details, see the EDGE Pro SERCOS II
Instruction Manual (807640).
