XM-R-200 Two Bus XM2BUS Communication Fire Serial Port Relay | Обустройство дома

I. overview XM-R-200 interface converter is an isolated XM2BUS repeater, which is used to expand the number of nodes or increase the distance between two buses. It inherits the characteristics of two buses with no polarity and arbitrary topology. XM-R-200 supports bus over-current and short-circuit protection with built-in fast transient suppressor and 1500W surge protection. Performance parameters 1. Electrical interface: 2EDG-5.8 terminal 2. Protection Level: 1500W Surge Protection of Two Bus Interface and Overcurrent Short Circuit Protection of Bus 3. Signal indication: Work (WK), Fault (BRK), Receive (RX), Send (TX) 4. Bus Load: 3A 5. Voltage range: DC 14-36V 6. Transmission medium: arbitrary conductor 7. Bus Connection: Arbitrary Polarity, Arbitrary Topology: Star, Tree, Bus 8. Communication Distance: <=1km 9. Number of nodes: <=200 10. Bus Bandwidth: 4500 BPS Connectors and Signals Power input     Bus input   Bus output       Troubleshooting 1. Failure of Data Communication A. Check whether the bus is malfunctioning B. Observe whether the RX and TX indicators flicker or not. C. Check whether the power supply is normal D. Observe whether the power/bus terminals are well connected 2. Data loss or error A. Check if the bus is not in good contact B. Check if bus current is abnormal C. Bus prohibits direct parallel connection of resistors, capacitors and other loads
