Hello,
I'm currently trying to recieve some data over RS232, using an Omron CP2E with an RS232 option board.
The device it's communicating with requires 5 volts to start spitting out data. It does so every second.
I have managed to recieve its messages by using the 5 volt output on the Omron's DB9 pin 6, which works ok but it causes an error when I use the Rxd instruction:
If I happen to execute the instruction in the middle of a message, then it doesn't agree and I have to reset the port using a bit in the auxiliary area.
It would help if I could use the Request to send pin for supplying 5 volts to the device, since then I could control when the message starts sending.
One problem, the RTS pin is pulled low (-5 volts) no matter what I do.
Could anyone explain me the workings of the RTS output and when it is switched high?
I use RS232 in no protocol mode, could that be the problem?
Info would be much appreciated.
