TCC-80I Serial Port Converter

Lead time 14-22 days
High-speed Isolated Serial Port Powered RS-232 to RS-422/485 Converter.
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.
