How far can RS-232 transmit?

40-50 feet
The maximum distance you can reliably run RS-232 signals is 40-50 feet. If you have a device more than 50 feet from the processor the solution is to use an ST-COM module.

What is the maximum distance for RS-232?

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 cable length for RS-232 communication?

Cable length is one of the most discussed items in RS232 world. The standard has a clear answer, the maximum cable length is 50 feet, or the cable length equal to a capacitance of 2500 pF.

How long can you run 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 the maximum baudrate of RS232?

But the main drawback of RS232 standard is data rate and length of cable. RS232 supports a maximum baud rate of 19200 bps and the maximum length of the cable is 20 meters.

What is the Max cable length for a RS232 part?

What’s the maximum serial cable length? The RS-232 standard specifies this as 15 metres (50 feet).

How far can I run a RS-232 cable?

The RS-232 standard 9600bps port will drive 15 metres of shielded cable. More precisely, an RS-232 line driver will operate against a capacitance of up to 2500 picoFarad with low enough skew to allow a 9600bps signal to be recovered. If you select a cable with lower capacitance you can drive further distances.

How long is a RS232 cable?

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).
