Use rs232 level converter, or alternatively rs485 transceiver.
I would need to use an RS-485 protocol to connect it with problem is that i confuse about how to do it? I will need to rs485 module to sent data from one to other and the second to sent it via an rs232 module to pc? IS this the case?
Greetings EveryBody! I AM USING: I am using B&B Electronics rs232 to rs485 converter (Model 485COSR, datasheet attached), for conversion it has MAX491 type full duplex IC in it and I connected this conerter with Computer via rs232 and on the other (...)
Hi i am developing a system based on modbus protocol.Master side is PC and slave are some other devices.I will need here an rs232 to rs485 converter b/w PC and slave devices.I know that i can connect 255 slave devices with 1 master. My question is that can i use 1 (...)
First check development kit documents of the CP21XX. for minimal implementation of RS-232 which uses only Rx and Tx you will need only a Phy. like MAX232. also for RS-485, a line driver/receiver IC like MAX485 is all you need. maxim and analog devices have several interface (rs232 (...)
Hello everyboday, I'm new here. We supply TTL/rs232/rs485 to WiFi modules, welcome your visiting.
You DEFINITELY don't want a cap there. For rs485 you need a terminating resistor, but not a cap.
Hello, This is my first post in the forum and i am honored to join the forum to be the start to learning the electronics. My problem in brevity i have barcode reader connect by rs232 i want to do I connect it to a distance of up to 150 meters for that i Decided convert it to rs485 and (...)
device is 3in1 converter: USB ? rs232, rs485 and UART. A fully dedicated system FT232RL acts as the converter. It is seen in the system as a COM port, and is assisted by two MAX232 and MAX485 systems. Any settings of the (...)
The system has RS-232 outputs in TTL and V.24 versions with all signals, what means DCD, RX, TX, DTR, DSR, RTS, CTS, RI. FT232RL system provides signal conversion USB-rs232 TTL. MAX235 system from MAXIMA samples is
please give me some details of usb to rs232, rs422 and rs485 converter applicable in military field.
Hi all, How to implement rs485 communication between PC and PIC micro controller. I have used MAX485 to convert RX and TX signal to D+ and D-. In PC side rs485 to rs232 converter is used. I think the hardware part (...)
Simple make rs485-rs232 converter. Use google, you can find a lot schematics. try: rs232<=>rs485<=>RS422 converters There you can find lots schematics for converter. Mr.Cube
hi friends! i wanted to implement rs485 communication b/w an avr and a pc.. the reason being distance up to 50 m b/w the two.. i am using the max485 ic, being the first time for such project wanted help and guidence.. i have a rs232-485 converter that i am going to use. (...)
simple introduction of rs-485 protocols, and rs232 to rs485 converter related information on this page. Expansion of Input and Output (I/O) Lines of a micro-controller and method of communications, please
Expansion of Input and Output (I/O) Lines of a micro-controller and method of communications, please have look on this. and rs232 to rs485 converter related information on this page. simple in
hi to all im interfacing the controller with a device which ll collects data from GPS receiver and converts it into rs485 format. my interfacing is made through a converter IC 26ls32(converts rs485-rs232) the prob is if i place the cable(b/w the device and (...)
1)what does +exc and -exc stand for, i think you are referring to supply +ve and -ve 2)what is the signal type? if the +signal and -signal are rs485 signals then you can hook it up to your rs232 port, if the signal is in (...)
Hi, you can use a rs485 bus to transmit at that distance. Just plug the PC to a rs232-to-rs485 converter, and at the other side do the opposite. You can achieve great distances with a rs485 bus.
