| Data Rate (max) | 1Mbps |
How far can you run RS-485 cable?
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 RS232 and What is it Used for?

How long the the RS-232 transmit data?
More formally RS232 is an asynchronous communication protocol that lets you transfer data between electronic devices. 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.
Why is RS-232 still used?
While USB has become the standard, RS232 is still widely used for older printers in the workplace. The RS232 protocol and cable allow the computer to give commands to the printer via a voltage signal. The printer then deciphers those commands and completes the print.
What are RS232 voltage levels?
Valid RS-232 signals are either in the range of +3 V to +15 V or the range −3 V to −15 V with respect to the common ground (Figure 1-1). To be more specific, the driver output is Logic 0 when the voltage is between +5 V and +15 V and is Logic 1 when the voltage is between -5 V to -15 V.
Does RS232 cable need to be shielded?
RS-232 serial interface cables should be shielded, low capacitance cables, ideally designed specifically for serial data transmission. The shield should be grounded at both ends of the cable.
How far and how fast can you go with RS-485?
The maximum recommended data rate in the RS-485 standard from 1998 is 10Mbps, which can be achieved at a maximum cable length of 40ft (12m). The absolute maximum distance is 4000ft (1.2km) of cable, at which point, data rate is limited to 100kbps.
Can RS-485 be daisy chained?
RS485 is a medium distance wiring system. It is daisy-chained and terminated at both ends of the daisy-chain.
Does RS-485 have a baud rate?
The RS-485 standard allows up to 32 drivers in one system, supporting communications over distances of up to 1200 meters, and can keep baud rates from 110 Baud to 115200 Baud. The RS-485 has several transmission line configurations.
Is RS-232 digital or analog?
technically, it is all analog (RS-232 uses voltage levels).
What is a RS-232 connector?
RS-232 was commonly used in computers to connect devices like a printer or a telephone modem. In computer terminology the RS-232 connector is often referred to as the “serial port”. The RS-232 port is not much used anymore. Connection of devices is nowadays done through the use of USB.

What is the idle state of RS-232?
The RS232 signals are represented by voltage levels with respect to a system common (power / logic ground). The “idle” state (MARK) has the signal level negative with respect to common, and the “active” state (SPACE) has the signal level positive with respect to common.
Is RS-232 obsolete?
Two of the oldest interfaces are RS-232 and RS-485. These legacy interfaces aren’t obsolete or discontinued, though. Both are still alive and well in many applications. The whole purpose of a serial interface is to provide a single path for data transmission wirelessly or over a cable.
What devices use RS-232?
A serial port complying with the RS-232 standard was once a standard feature of many types of computers. Personal computers used them for connections not only to modems, but also to printers, computer mice, data storage, uninterruptible power supplies, and other peripheral devices.
Is RS-232 full duplex?
RS-232 operates in a full duplex mode, meaning the controller and receiver can communicate at the same time without interference. Mensor transducers with RS-232 require three wires for set up: Transmit Data (TX), Receive Data (RX), and Signal Ground.
Is Rs 232 a protocol?
RS232 is a standard protocol used for serial communication, it is used for connecting computer and its peripheral devices to allow serial data exchange between them. As it obtains the voltage for the path used for the data exchange between the devices.
What is the recommended maximum length of an RS 232 connection when operating at 20000 baud?
The RS-232 standard specifies this as 15 metres (50 feet).
Does RS232 need a ground?
Due to the way the signals are connected, a common ground is required. This implies limited cable length – about 30 to 60 meters maximum. (Main problems are interference and resistance of the cable.) Shortly, RS 232 was designed for communication of local devices, and supports one transmitter and one receiver.
Does RS232 need twisted pair?
RS-232 EASY & UNIVERSAL COMMUNICATION INTERFACE
RS-232 is simple and low cost and differs from RS-485 only in the fact that it uses hardware switching to physically control the direction of communication and does not require twisted pairs of wires because it does not use a differential signal.
Can I use Cat6 for RS232?
the adapter run RS232 data over long distances (up to 100m) using UTP Cat 5/ Cat6 cable to bridge the gap.
Is RS-485 a protocol?
RS-485 is still the most widely used protocol for POS, industrial, and telecom applications. The wide common-mode range enables data transmission over longer cable lengths and in noisy environments such as the floor of a factory.

CAN bus vs RS-485?
RS-485 was defined for the industrial market, while CAN was primarily developed for the automotive/vehicle/transportation segment. Since its release, the CANbus interface has slowly been adopted to applications outside of the automotive and aerospace industries.
Can we use CAT6 cable for RS-485?
A good economical solution for field wiring is to use CAT5 or CAT6 twisted pair cable.
