Problem

1. Machine is running, but not collecting any data or stuck in the same status
   

Reason

1. The most common reason is due to the DataXchange Service not being able to communicate with the SRC
   

Solutions

1. Basic
   
1. Ping the Moxa device to confirm connectivity (best done from the DataXchange Service computer)
   
1. If no response, troubleshoot the network connection by checking physical connections such as loose cables, confirm there is a link light, correct VLAN configuration, etc. If you're still having trouble, consult with your IT team
   
2. Confirm no firewall rules are in place blocking TCP ports 4001 and 4002
   
3. Confirm the Equipment is configured and running in the DataXchange application
   
4. Confirm the Moxa device was configured for TCP Server mode
   
2. Advanced
   
1. Both the SRC and Moxa device have serial activity lights that are extremely helpful for troubleshooting
   
1. SRC has a TX2 and RX2 serial activity light
   
2. Moxa NPort 5110 has a Tx/Rx serial activity light
   
3. Moxa NPort W2150A, W2250A, or 5250A have Serial 1 activity light for Port 1 and Serial 2 activity for Port 2
   
2. Normal connectivity is seen with the Moxa serial activity light flashing green, then flashing orange shortly after, this repeats every 5 - 10 seconds, the SRC presents the same except TX2 flashing green, the RX2 flashing green shortly after
   
3. You do not see the Moxa serial activity lights flashing any color; the hardware and/or software configuration needs to be checked, contact SFA Technical Support
   
4. You see the Moxa serial activity lights flashing, but no response; confirm the serial cable is plugged into Port 2 on the SRC, confirm the serial cable is plugged into the correct port on the Moxa device (should match based on the serial activity light you see flashing); its possible the cable is bad
   
5. You see the Moxa serial activity lights flashing, but no response AND the SRC TX2 serial activity light flashing, but no SRC RX2 response; unplug the SRC, wait 5 seconds and plug back in, check all of the above once more
   
6. You see the Moxa serial activity lights flashing, but no response AND the SRC TX2 serial activity light flashing AND the SRC RX2 serial activity lights flashing; its possible the cable is bad
