FACET® Base Units
The FACET Base Units provide necessary protection and voltage conditioning circuitry to run each FACET Circuit Board. To accommodate a variety of system configurations, Lab-Volt offers four base unit models: two for the computer-based system configuration (one with built-in power supply and one without) and two for the manual system configuration (one with built-in power supply and one without).
Each computerized base unit communicates with the computer through a serial communication port. The base unit's on-board microcontroller sends system status to the host and receives control commands required to set and reset circuit-modification and fault controls.
Each manual system base unit comes with an accessory kit containing terminal posts, connectors, adapters and patchcords required to perform experiments on the FACET training modules. Circuit modifications and faults are controlled by a bank of 32 toggle switches located on the base unit (12 fault switches are located under a lockable cover)
