Hi, I'm trying to make an rs232/rs485 converter circuit. I used a circuit from and i changed some components on that circuit. Then i established my converter circuit that i linked the scheme. I'm also adding
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?
You DEFINITELY don't want a cap there. For rs485 you need a terminating resistor, but not a cap.
Hai, Iam doing a project in which i have connect 10 to 15 Micro Controllers to one PC. so i have used rs232 to rs484 converter at PC and ds75176 ant each Micro Controllers. I have a question that is that possible. and while the 1st MC send data to PC at the same time if MC2 and some other MC's are send different data to PC then the PC can t
Im using MOXA's rs232 to rs485 port powered converter connected to my computer using a rs232 cable and i am supposed to send a byte/signal to it using hyperteminal but i do not know how?? ive configured my hyperteminal... its jus blank any1 could help mi?? thx in advance
Hi, I have made a rs232 to rs485 converter , circuit is taken from control.html But the Modbus device using rs485 is not available now . So to test the converter I have made two converters and rs232 of both
A simple RJ45 to DE9 cable won't work, you need a converter like the ones found here.
I have a problem communicating between PC to AVR. I got a rs485 converter that can convert from rs232 (PC) to rs485. I can use it for PC-to-PC, but I failed using it for PC-to-AVR. I am not sure about the sampling methodology of PC uart. Could this be a problem since the the converter (...)

Bus-powered rs232-rs485 converter can be implemented with single MAX3162 chip (+4 capacitors). Check this link for details and schematic: Ace-X.
Probably this help you, it is in Italian.. good luck :roll:
