2 INTRODUCTION
Electrical Teleprotection is an optional feature that uses communications links to create protection schemes. It can
be used to r
eplace hard wiring between dedicated relay output contacts and digital input circuits. Two products
equipped with electrical teleprotection can connect and exchange commands using a communication link. It is
typically used to implement teleprotection schemes.
Using full duplex communications, eight binary command signals can be sent in each direction between
connected products. The communication connection complies with the EIA(RS)232 standard. Ports may be
connected directly, or using modems. Alternatively EIA(RS)232 converters can be used for connecting to other
media such as optical fibres.
Communications statistics and diagnostics enable you to monitor the integrity of the communications link, and a
loopback feature is available to help with testing.
