WebThe Advantages of RS485 and RS422 vs RS232 RS485 and RS422 use differentiation. Two wires are required for each signal. The figure below shows a single RS485 / RS422 signal being transmitted. To transmit a logic 1, line B is high and line A is low. To transmit a logic 0, line B is low and line A is high. WebThe original RS232 protocol was based on using ±12V for logic signal levels. Nowadays, TTL-based RS232 signals are used commonly where the original data transmission protocol remains the same but the logic signal level is reduced to ±5V or ±3.3V to make it compatible with the microcontroller inputs. WebTTL and RS232 signals differ solely at a hardware level. By the RS-232 standard a logic high ('1') is represented by a negative voltage – anywhere from -3 to -25V – while a logic low ('0') transmits a positive voltage that can be anywhere from +3 to +25V. On most PCs these signals swing from -13 to +13V or even from -7 to +7V. galt veterinary clinic

WebI would suggest using a MAX232 based chip instead. This seems to shift the RS-232 15V logic down to 5V TTL, but I do not believe it shifts 5V TTL up to 15V logic. The MAX232 based boards will do this. If you know more than me, go ahead and give it a shot. Otherwise, the MAX232 based boards work right out of the box. WebLogic (1 or 0) D A B +!

WebI have a RS-232 device trying to get it to 3.3 TTL. To pull that off, you have to route the RS-232 device into the RXIN and the uC out of the RXOUT. I initially had it going into the TXIN and uC out of TXOUT, but that kept logic levels higher than my Vin. Hopefully something that might save a poor uController some day. 5 of 5 found this helpful:
