CANpro/104 User Manual
Security ID Feature
Some users may wish to associate the operation of their software with a particular hardware installation. To support this ability, an ID mechanism is available which uses a simple, somewhat unusual (but predictable) Write/Read mechanism by which software can determine that the CTI CANpro/104 board is installed. This feature is only available when the CANpro/104 board is operated in “Memory Mode”. Contact CTI Technical Support for information about the method and algorithm required to use this feature.
Jumper Summaries
The following tables of Jumper settings are useful once the user is familiar with the operations performed by those jumpers.
