General description. The RS485-TTL ”INTR” interface enables connecting the PSU of PSBEN and EN54 series to the RS485 bus with full galvanic isolation.
www.pulsar.pl INTR 3. Connection to the RS485 bus. 3.1. System structure in the RS485 bus. Use a twisted-pair cable as a transmission wire of the bus. The ”point-to-point” topology is recommended, while the ”star” topology should be avoided. If the wires are long enough, it is recommended to use shielded cables to avoid errors during the communication and to lower the susceptibility to noise and radio interference.
www.pulsar.pl INTR 4. Configuration of power supplies. Communication in the RS485 bus requires setting appropriate communication parameters in all devices and assigning of unique addresses. The configuration of power supplies uses a display located on the front panel of the enclosure. Depending on the display type - LED or LCD - the procedure for changing the settings is different. 4.
