Hi, All,
I am looking for a off the shelf RS232 to inverse RS232 converter. Preferly it should have 2 DB9 connectors without external power supply. One DB9 will take in normal RS232 signal (+10V means low and -10V means high). After conversion inside the circuit, another DB9 will output inverse RS232 signal (+10V is high and -10V is low).
Anyone come across these types of devices?
Please advice.

regards
 

Push pull arrangement will do this with proper supply voltage .
 

Often you may found half RS232 inverted (transmision inverted, receiver not or viceversa) but never totaly reversed RS232 (at least I have never seen that completely reversed configuration before).
