Overview
Description
The RTKA788152DE0000BU RS-485 evaluation board is used to evaluate the half-duplex transceivers of the RAA78815x family of RS-485 transceivers.
The RAA78815x family includes half and full-duplex transceivers with active-high driver-enable pins and active-low receiver-enable pins. These transceivers support data rates of 115kbps, 1Mbps and 20Mbps with a performance that is characterized from -40 °C to +85 °C.
Features
- Single 115kbps half-duplex transceiver
- RAA788152 (115kbps version currently installed) can be unsoldered and replaced by RAA788155 (1Mbps version) or RAA788158 (20Mbps version)
- Placeholders for fail-safe biasing resistors
- Configuration jumpers to operate the transceiver as transmitter or receiver, or as a transmitter with loopback
Applications
- Industrial networks in factory automation
- Building automation: lighting, elevators, HVAC
- Industrial process control networks
- Security camera networks
- Networks with star topology
- Long-haul networks in coal mines and oil rigs
- High node count networks
- Automated utility e-meter reading systems
