Frequently Asked Questions (FAQ)

Q: What is the primary function of the T8311 module?

• A: It acts as a communication interface to connect a main Trusted TMR controller to one or more remote I/O expander chassis, significantly increasing the total number of I/O points available to the system.

Q: Can I use standard Ethernet cable instead of TC-301?

• A: No. The communication requires the specific TC-301 copper cable or a fiber optic conversion setup for proper signal integrity and noise immunity over the specified distances.

Q: How many expander chassis can one T8311 module support?

• A: The specific number depends on the system configuration and load. You must consult the Trusted system design guidelines or technical documentation for cascading limits and best practices.
