The SAM-422 is an inline surge protector intended to protect an RS-422 link against egregious surge events, such as those produced by lightening strikes. In addition to providing protection against primary surge events, the SAM-422 includes a pass-through interface which can be used in cases where the surge-protected link has been damaged. The SAM-422 also includes a loopback connection for convenient diagnostics of RS-422 connected equipment.
