Troubleshooting
For questions about your product or customer service inquiries, please call our toll free number (877-BIG-FANS).
Some issues can be resolved before requesting service. Review the below troubleshooting tips before contacting Customer Service for
support.
Symptom Possible solution(s)
Intermittent or permanent communication
losses with fans (RS-485)
The RX and TX network activity
indicators in the bottom left corner of the
BAFWorks
®
application screen (see item
C on page 59) are cyclic under normal
circumstances. If you do not observe
a normal rhythm of RX (green) and TX
(orange), data packet loss or corruption
within the Modbus data loop may have
occurred.
Verify the following:
• All components are plugged in
• The fan controllers are programmed properly (address, protocol, etc.)
• Terminating resistors are installed only where required
• All cable and communications card connections have been tug tested
• The Modbus cables are generally isolated or shielded from AC power circuits. A
quality shielded cable should be used. Per standard installation, the cable shield is
landed in parallel with the cable’s reference line. If all shields are tied together, Big
Ass Solutions recommends bonding the cable shield to Earth/PE/Ground. Do this in
one spot only! If bonded in multiple locations, a ground loop will result.
• The cable does not exceed distance limitations. This is a dynamic situation. There is
no definitive way to know the control system’s limitations for certain. If everything else
has been ruled out, contact Big Ass Solutions Customer Service about the use of a
wireless RS-485 repeater. This will replace a long run of cable, but it requires setup
and a suitable low voltage DC supply at each radio module. Installation challenges
may exist.
Communication loss between the iPad
®
and the BAF gateway/Wi-Fi router
The yellow network activity indicators in
the bottom left corner of the BAFWorks
application screen (see item C on page
59) confirm the connection between the
iPad and the Wi-Fi router. If the top two
indicators are not yellow, communication
has been lost between the iPad and the
router.
Verify the following:
• The iPad is being directed to your router/gateway combination. This can be verified
on the iPad under Settings > Wi-Fi > Choose a Network .
• The router settings and iPad Wi-Fi configuration are correct.
Ports used by ADAM modules on corporate networks
If you are running BAFWorks using a corporate network instead of the provided Wi-Fi router, the network firewall, wireless controller,
or other network component may block UDP/TCP traffic. If this occurs, the ADAM modules will not be able to communicate with the
BAFWorks system. When troubleshooting communications issues on a corporate network, note the following ports used by the ADAM
modules for UDP/TCP communication.
UDP/TCP ports used by ADAM modules (initial mode)
Function Protocol Port
UDP ASCII communication UDP 1025
Datastream UDP 5168
GCL IO message UDP 5168
P2P message UDP 1025
Search engine UDP 5048
TCP ASCII/Modbus communication TCP 502
Download TCP 5450
Download Adam6024 TCP 7000
When the ADAM modules are in normal mode, they follow the standard of Ethernet/IP. TCP port number 44818 is used for explicit
messaging and UDP port number 2222 is used for implicit messaging.
