15. Verify the CK721-A controller firmware version number. If the
installation was successful, the firmware is listed as 3.3 Build-14. The
CK721-A firmware version appears a few lines above the Login
prompt (see the highlighted area of the previous screen capture).
If the version number is not 3.3 Build 14, then the firmware
installation failed (see Troubleshooting on page 17 for more
information).
16. Repeat the steps in this section for each controller you are upgrading.
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 (besides
Windows XP Firewall)?
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
