3.1. Resolving Installation Problems
If installation fails or you are trying to resolve a problem, you should try the
following before calling the Comtrol technical support line:
•
Check the signals between your peripherals and the interface box to verify
that they match (if applicable). See the appropriate Hardware Reference
Card for information.
• Check to make sure the serial and interface cables are connected properly.
• Check to see if the DIP switch is set to the desired address by checking the
/ROCKET/INSTALL.LOG file with an editor against the settings on each
controller.
• Reseat the controller in the slot.
• Make sure that the expansion slot screw was replaced after inserting the
controller.
• Reinstall the API , selecting a different I/O address range for the controller.
For possible I/O address conflicts, see Tables 3-1 and 3-2.
Table 3-1 defines the 64-byte I/O address blocks from 0 through 3FFh and their
known uses. Table 3-2 defines the 64-byte I/O address blocks from 400 through
FFFh and their known uses.
