Transceivers encrypt wireless data to
boost safety
Schweitzer Engineering Laboratories (SEL) is announcing the SEL-3022 wireless encrypting transceiver that can improve safety and reduce operating costs.
Schweitzer Engineering Laboratories (SEL), a leading manufacturer of protection, monitoring, encryption, control, automation, and metering equipment, is announcing the SEL-3022 wireless encrypting transceiver Concerns about the security of wireless communications have led some organisations to adopt policies prohibiting wireless data links

SEL-3022 wireless encrypting transceivers address those concerns by supplementing standard wireless communication security protocols (ie WEP) with National Institute of Standards and Technology (NIST) approved 128-bit AES encryption and HMAC SHA-1 message authentication algorithms.
The SEL-3022 allows users to securely apply wireless communications links between a portable computer and remote devices.
SEL encrypted serial port software is included to encrypt serial-port data and send it to a remote SEL-3022, using the PC's standard wireless ethernet interface.

The SEL-3022 can be applied to lock out cyberintruders, improve personnel safety, protect equipment, and increase physical security.
These secure wireless links improve safety by enabling personnel to operate breakers, valves, reclosers, gates, and other equipment while they remain outside hazardous areas or in a vehicle.
They can avoid hazards from blowing debris, extreme heat and cold, traffic, crowds, freezing rain, ice, snow, floods, animals, arc flash, electrical conductors, and more.
Remote links protect equipment by allowing users to keep doors closed on outside equipment enclosures and control houses to prevent contamination by blowing dust and debris, precipitation, insects, and hot, humid, or cold air.
This also minimises wear on door seals at cold temperatures.
Remote access improves site security, by keeping doors and gates locked, and eliminating opportunities for intruders to gain access by following or coercing service personnel.
This also reduces the number of physical keys that need to be in circulation by granting only wireless access as appropriate.
Remote access allows installation of control boxes and other equipment out of the reach of vandals or other intruders.
SEL-3022 wireless encrypting transceivers can be used to save time and money by avoiding the use of protective barriers, signs, traffic diversion cones, or arc-flash protective clothing.
Users can also eliminate delays for security screening, arranging for escorts, or special access permission to monitor equipment located in secure areas controlled by others at airports, government facilities, and secure industrial and commercial locations.
SEL offers local technical support and a worldwide, ten-year product warranty.
