Solution NI provides the following options for TPM support: PXI TPM is not supported on any PXI controllers. PXIe The PXIe-8880 supports TPM 1.2. The PXIe-8861 supports TPM 2.0. The PXIe-8881 supports TPM 2.0. Rack Mounted Systems The RMC-8357 has the ability to support TPM 1.2. According to the PXI Advisor, the NI PXIe-8880 runs NI Real-Time Linux but according to this document it runs Phar Lap ETS. Also, the manual mentions Linux (in the general sense: "With LabVIEW for Linux and support for over two hundred devices on Linux ") but not Phar Lap ETS. Can somebody tell me which one is correct? Phar Lap is a 32 bit system so it can support up to 4 GB only. On the other hand, NI Linux RT is 64 bit system. Its memory limit is determined by the maximum memory supported mentioned in controller user manual/specification. For PXIe-8880 (Phar Lap), the maximum amount of RAM on Phar Lap is 4 GB due to 32 bit OS limitation. PXIe-8881 and PXIe-8880 The PXIe-8881 has an AMD Radeon™ E6465 and the PXIe-8880 has an AMD Radeon™ E6460, both with a DisplayPort 1.2 output from the Embedded GPU. You can daisy-chain multiple monitors to the DisplayPort 1.2 connector. PXIe-8861 The PXIe-8861 has one DisplayPort 1.1 connector and one DisplayPort 1.2 connector.
