The Moxa 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.

Main Features:
 
 * Self-powered or selectable external power source
 * High-speed transmission up to 115.2 Kbps
 * 2.5 KV Isolation
 * Compact size
 * Selectable 2/4-wire RS-485 and RS-422 conversion
 * RS-485 automatic data direction control
 * Surge protection, 15 KV ESD
 * Built-in 120 Ohm termination resistors
 * Patented LED Port Power Indicator

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.

The RS-232 port of the Moxa TCC-80I is designed with a female DB9 socket to connect directly 
to the host PC, with power drawn from the combination of TxD, RTS, and DTR lines.

Patented LED Port Power Indicator is designed especially for the TCC-80I.
