Plus/minus 3 to plus/minus 15, with a maximum open circuit range of plus/minus 25.
For a status line, such as DTE or CTS, plus is true, minus is false. For a data line, such as TXD or RXD, minus is marking or 1, plus is spacing or 0. (Note the inversion at the UART.)

What is 232 in RS232 and MAX232?
The difference between max232 and rs232 is the voltage levels of the rs232 are high. In order to reduce those voltage means to convert those voltage levels to TTL logic levels we use max232 integrated chip which is a dual driver/ receiver.
Why ttl voltage level converting to rs232 level?
Whwn an IC is connected to a PC, then the voltage levels of these two should be synchronized. For this purpose, the TTL voltage level is converted to RS 232 level. RS 232 is the interface between a PC and an IC.
Why do you connect capacitor in MAX232?
The input to the max232 ic will be of Transistor Transistor Logic (TTL) and its voltage range will be of 5 volt. The output of the max 232 ic will be of Recomended Standard 232 Logic (RS232 logic) and its voltage range will be of 12 volt. The max 232 ic which is operating on 5 volt supply has to step up the 5 volt input to 12 volt. Hence a capacitor is used for pumping the voltage and called as pumping capacitor.
What do you use in laptop - rs232 or rs485?
rs232
What are the Differences between RS232 and RS449?
rs232 isfaster than rs449
What is chopper amplifier?
In a chopper type amplifier the dc i/p voltage is converted into an ac voltage, amplified by an ac amplifier and then converted back into a dc voltage proportional to the original i/p signal
Make USB to RS232 converter?
Yes, you can get a USB to RS232 converter (aka USB to Serial).
What is the difference between rs232 and rs485 port?
Difference between Rs232 and RS485 is Only Distance RS232 is not for long or far distance .. but RS485 can be use for LONGEST distance ..RS232 is single ended communication where as RS485 is Differential communication.Max.no of receivers in RS232 is only ONE, whereas in RS485 is 32.Max.no of transmitters in RS232 is only ONE whereas in RS485 is 32.IN RS232 there is no pin to change from transmitter mode receiver mode. But, In RS485 have DE pin to set transmitter mode and RI to set receiver mode.
What range should you set the voltmeter prior to taking a voltage measurement?
Make a guess of what the voltage will be and set the range accordingly. If needed, change the range after measuring the voltage, to get a better reading.
Where can one purchase RS232 cable?
One can purchase a RS232 cable at most electronic stores. A few common examples of stores that have RS232 cables for sale are Best Buy, Radio Shack, and Fry's.
What is the acceptable range of ac voltage at an outlet?
The acceptable range of ac voltage at an outlet is from 115 to 120 volts. The utility company has a mandate to keep the voltage within a 10% fluctuation range. The catch is 10% from what set point voltage.
Full form of RS in RS232?
RS232 means "Recommended standard no. 232", EIA standard for serial communication Thirumalesha.....
