Zigbee to RS485 Repeater, 3 Input Module
Zigbee repeater is a kind of low cost, low consumption, and wireless mesh network targeted at wide development of long life devices in wireless control and monitoring applications.
OR 485 Isolated Converter/Repeater
The OR-485 is an externally powered isolated converter/repeater with diagnostic LEDs.There are two input ports which can be designated, via jumper, as either RS232( for connection to a PC as a converter), or RS485 (for bus repeater mode). The isolated, half-duplex RS485 output port has two separate connectors to make dividing the network simple for troubleshooting. The diagnostic LEDs show common wiring mistakes such as short or open circuits. All protocols (Bacnet, Modbus, generic RS485 protocols, etc.) are supported. Some of the diagnostics, such as “bad CRC” and “Modbus” error reporting, however, are available only with Modbus at 19.2k or 9600 baud.
