Overview
The TCC-80I is the world's first high-speed, serial port powered converter with 2.5 KV isolation. The TCC-80I draws power from the attached RS-232 device, and provides complete RS-232 to RS-422/485 interface conversion and electrical isolation protection. The TCC-80I converts between the RS-232 TxD and RxD lines and half duplex 2-wire RS-485, or full duplex 4-wire RS-422/485. The TCC-80I's outputs come with built-in 15 KV ESD surge protection to provide comprehensive protection against current overload. The TCC-80I also supports RS-485 automatic data direction control, in which the RS-485 driver is enabled by circuitry when the RS-232 TxD output is sensed. This means that no programming effort is required to control the direction of the RS-485 signal.
