NI PXI-842x legacy modules are asynchronous RS232 interfaces available with up to 16 ports. The two PXI-8422 modules are identical but offer 2000 V of optical isolation with two or four ports. PXI-842x legacy modules have been replaced by NI PXI-843x next-generation serial interfaces, which offer increased performance and functionality at the same price as the legacy modules. Use NI legacy PXI modules, which are available in 2-, 4-, 8-, and 16-port versions, only with Windows Me/9x/NT.
