The typical configuration for A/V equipment is: Data Bits - 8, Parity - None, Stop Bit - 1. The end of the transmission session is defined by the Stop Bit which can be set to 0, 1, or 2.

If this is not important for your program, you can set this parameter to None. Parity indicates whether the number of 1s in a single transmission is odd or even. This parameter can be set to either 7 or 8. Also, you should properly configure the number of Data Bits - bits transmitted in a single character. That means if your computer’s COM port is set to operate at 2400 baud, you need to have your device set to 2400 baud as well. Such parameters as Baud rate, Data Bits, Parity, and Stop Bits must match on both systems. In order for communication to be efficient, the connection settings for both the controlling system and the connected device must be identical.

If your hardware connection is correct, but the serial communication still cannot be established, the problem may lie in improper software settings. Software problems and the optimal solution There are two most common serial port problems: software incompatibilities that result in a non-working serial port and faulty wiring that causes connection issues. Learn more about RS232 serial cable and what is the difference between a null modem and straight through serial cable Serial port troubleshooting If you are transmitting at 9600, your cable should be a maximum length of 50 feet, etc. For example, a standard 100-foot cable is generally used when the baud rate is from 1200 to 2400. With the increase of the baud rate, the length of your RS232 cable linking A/V equipment to the controlling system decreases. Note: The higher a serial port baud rate, the more data can be transferred in less amount of time. You have to set the same baud rate on both sides of using machines. Typically, COM port baud rates fall into the range of 1200 to 19200. The rate at which information is transferred over the RS-232 communication channel is known as baud rate. In case you can’t avoid running these signals close to each other, you need to make sure that all of your audio wires are properly shielded. What you should remember is that large voltage fluctuations in RS-232 signal lines can cause substantial electrical noise, so it’s not recommended that you run RS232 signals near a high-impedance microphone or audio lines. The wide range of voltages used by the RS-232 port makes possible the compatibility with different types of A/V equipment. Besides, RS-232 ports can work with voltages as low as -5V to +5V. The voltage swings, occurring while transporting data, can total 30V. Another type of connector, terminal block, is becoming more end more popular as it enables simple installation without soldering.Ī standard voltage for all RS-232 signal pins ranges from -15V to +15V. For instance, it may happen that the pins 2 and 3 are reversed which allows the connection to be made with pin-to-pin wiring between a 9-pin connector and a 9-pin cable.

At the same time, the pinouts on your controlling system or computer can differ from those used on the A/V devices. A/V equipment usually comes with a 9-pin connector. Some of them serve for port loopback testing.

If you want to use the DB-25 connector, just replace the pin numbers of the connector according to the conversion table below.Īs for the 25-pin connector, not all of its pins are used for sending and receiving serial data. In mixed programmes, a 9 to 25 pins converter can be used to unite connectors of different sizes. However, since the introduction of the smaller serial port on the IBM-AT, 9 pins RS232 connector has become more widely used. The original pinout for RS232 was developed for 25 pins connector. RS-232 Pinoutsīelow you’ll see the typical pinouts of RS232 connectors.

Your communication software usually overrides the parameters set by Windows Device Manager. There is a set of parameters that needs to be configured for the serial communication – baud rate, parity, number of data bits, stop bits, flow control, etc. Basic characteristics about COM Port protocol
