How RS-232, RS-422 and RS-485 Networks are applied in Instrumentation
RS-232 Presently, this standard is known as TIA-232C. These are point-to-point networks with a purpose of connecting only two devices. The signaling is single-ended (unbalanced) which implies that the respective voltage pulses are referenced to a common ground conductor and … Read more
