The voltage level was initially ±24 V PP and dropped to ±12 V PP with EIA RS-232-C. There serial protocol could vary and ...

Typical computer data communications involve the use of an RS-232 port. RS-232 communication, however, operates using asynchronous data transmission.

Each synchronous channel is individually configurable for RS-232, RS-422, RS-485, RS-530/530A or V.35. Relio systems are designed using COM Express architecture, require low power consumption, operate ...
