What is the maximum distance for RS485?
4,000 feet
RS485 is popular for inexpensive local networks, multidrop communication links and long haul data transfer over distances of up to 4,000 feet.
What is the maximum distance for RS232?
50 feet
The RS-232 standard specifies this as 15 metres (50 feet). However this is a conservative figure accounting for high serial speeds over high capacitance cabling, for example using a baud rate of 9600 (a common console speed) over typical Cat 5 cabling, the maximum length increases to 100 – 150 meters (328 – 500 feet).
What is the distance supported by RS232 protocol?
Table 1. RS-232 Specifications
| RS-232 | |
|---|---|
| Communication Mode | Full duplex |
| Distance (max) | 50 feet at 19.2kbps |
| Data Rate (max) | 1Mbps |
| Signaling | Unbalanced |
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.
Why is the rs232c cable limited to a maximum length of 15 meters?
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 difference between 232 and 485?
Data Transmission Speed RS232 is more than able to perform for a short distance and low data speed requirements. RS232 has a transmission speed of 1Mb/s up to 15M. However, RS485 has a data transmission speed of up to 10Mb/s for a distance of 15M. At the maximum of 1200M, RS485 transmits at 100Kb/s.
How long does it take rs232 to transmit data?
Basically it can transfer a single byte of data over a serial cable having between 3 to 22 signals and running at speeds from 100 to 20k baud. Common baud rates used are 2.4k, 9.6k, 19.2k, The cable length can be up to 50ft.
What are the advantages of RS485 over RS-232?
The RS485 has many advantages over both RS232 and USB when it comes to applications in noisy industrial environments. It was designed from the beginning to be tolerant of noise and forgiving of long cable runs. It achieves this by using a differential current drive output which has high immunity to noise.
