What is the maximum cable length for RS485?

CABLE LENGTH AND DATA RATE RS422 and RS485 specified maximum cable length is 1200 meters. The maximum working data rate (in bits per second – bps) depends on network devices characteristics, cable capacitance and installed termination resistors. The longer the communication cables, the lower the maximum data rate.

How long can a RS-232 cable be?

50 feet
The RS232 standard does not define a maximum cable length but instead defines the maximum capacitance that a compliant drive circuit must tolerate. A widely used rule of thumb indicates that cables more than 50 feet (15 m) long will have too much capacitance, unless special cables are used.

What is the maximum length of a serial cable?

Serial (RS-232) – The maximum cable length that we suggest is 50 feet. At lengths greater than 50 feet, there may be a loss in signal integrity which may affect data.

What is a RS-485 cable?

RS-485 is an industrial specification that defines the electrical interface and physical layer for point-to-point communication of electrical devices. The RS-485 standard allows for long cabling distances in electrically noisy environments and can support multiple devices on the same bus.

Is RS-485 a protocol?

RS485 is a protocol similar to RS232 that is used to implement serial data communication. The two protocols use different electric signals to enable data transmission.

Is RS485 a protocol?

Can you convert RS-232 to RS485?

RS232 to RS485 converters can be either isolated or non-isolated. An isolated RS232 to RS485 converter have optical isolators separating the data lines inside the unit, this prevents noise, high voltage spikes, surges and ground-loops from damaging your computer or the equipment you have connected to the converter.
