Hello, I'm developing a project where 3 devices will either transmit or receive (NEVER at the same time), but the problem is that two of those devices have the RS232 protocol predefined (one of them is a PC, the other one is a scale). So I think my only option in order to communicate those 3 devices, is to use converters to RS485 (please correct me if I'm wrong), like these http://img.dxcdn.com/productimages/sku_6040_1.jpg. But I can´t find (I'm not a native english speaker, so probably I'm not using the right key words for the research) any information about the transmit enable bit (like the one in a MAX485). So that is worrying me because I don't know whether the peripherals are going to be talking/listening when I need them to.
Please!! Any info will be appreciated. Thank you!
(I'll use half-duplex, asynchronous mode)
