Moxa TCC-80 - serial adapter - RS-232 - RS-422/485

TCC-80, which is powered via the RS-232 ports, provides complete signal conversion between RS-232 and RS-422/485. TCC-80 converts back and forth between RS-232's TxD and RxD lines and either half-duplex 2-wire RS-485 or the balanced signal of full duplex 4-wire RS-422/485. In addition, TCC-80's outputs have comprehensive protection against current overload with built-in 15 KV ESD surge protection. TCC-80 is also designed to provide RS-485 auto data direction control in which the RS-485 driver is enabled automatically when the circuitry senses the TxD output from the RS-232 signal. This means that no programming effort is required to control the transmission direction of the RS-485 signal.
