SEL-3021 Serial Encrypting Transceiver
Schweitzer Engineering Laboratories, Inc. - FIPS 140 #782
The SEL-3021 Serial Encrypting Transceiver is a bump-in-the-wire encryption device providing strong cryptographic security to new serial communications links and an easy and effective security solution for existing serial communications networks. It is for use on both point-to-point byte oriented communications links and multi-drop networks. The SEL-3021 has preset configuration settings for popular SCADA or PCS protocols like DNP and MODBUS common to PLCs and RTUs. The SEL-3021 also has support for standard MODEM communications.
