Model 570E/542 Dual Function Fiberoptic Transceiver With
FiberLoop III System

The Model 570E/542 dual function transceiver combines all the features and performance of our newest Model 570 transceiver with full support for legacy, 542-based networks. The 542 functionality allows this transceiver to function as a 542 network adapter while providing the latest 570 technology and the full FiberLoop III system control and monitoring support. The FiberPanel system software included with the 570E/542 supports multiple RTUs, Intelligent Electronic Devices (IEDs), Programmable Logic Controllers (PLCs) and microprocessor-based relays.

This dual function transceiver provides the same functionality as the standalone 570 transceiver. It supports the Model 570E self-healing, single mode fiberoptic features and provides 126 high speed (56Kbps) independent virtual network communication channels with four to sixteen serial ports. You can assign a transceiver serial port to any virtual channel, which allows grouping Remote Terminal Units (RTUs) with common protocols. Two 10/100 802.3 compliant Ethernet ports are also available as an option.

The 570E/542 FiberLoop III system allows segregating different applications, allocating network bandwidth, and sharing backup master stations as required for your unique network configuration. The system supports peer-to-peer communication and all byte protocols including DNP and UCA. In H&L's redundant loop configuration, the system self-heals from loop to radial mode so quickly (4 msec) that relays such as the SEL-351 cannot detect the fiber break.

The dual function 570E/542 transceiver can be configured as a 570, as a 542, or as a combination 570/542 device, and is optimized for use with Schweitzer Engineering Labs Mirrored Bits Protocol™. The 570E/542 dual function transceiver and network adapter utilizes the latest surface mount technology and draws only 1/2 Watt more than a standalone Model 570E. This unit is highly reliable, fault-tolerant, redundant, and offers both a rugged and cost-effective solution for adding self-healing ring and radial network designs to new and existing networks.
