Troubleshooting
If the firmware installation fails, answer the following troubleshooting
questions:
Are you are using the correct cable types?
For example, are you using the correct network cable (straight-through
versus crossover)? Check the pin connections if you constructed the
cables yourself. See Cable Wiring on page 2 for more information.
Did you correctly connect the serial null modem and network cables
to the CK721-A controller and computer?
See Figure 1: Connections between Computer and CK721-A Controller
for reference.
Does your computer have Firewall software installed?
If so, you must disable it in order to successfully upgrade the CK721-A
controller firmware.
Did you correctly configure your computer?
Review the required changes to your computer settings as listed in
Table 1: Computer Settings. Verify that the settings on your computer are
correct.
If the firmware installation still fails after performing the previous
troubleshooting steps, the CK721-A controller has experienced a
hardware failure. Return the defective controller to Johnson Controls by
initiating a Return Material Authorization (RMA). To do this, contact
your Johnson Controls Representative or enter an RMA at this Employee
