Description

The Moxa TCC-80I is a port-powered RS-232 to RS-422/485 serial converter designed for industrial and commercial serial links that need reliable signal conversion without an external power supply. It adds 2.5 kV isolation to protect connected equipment, and a LED port power indicator confirms the unit is drawing enough power from the host port.

The converter supports 2-wire half-duplex RS-485 and 4-wire full-duplex RS-422/485, with automatic data direction control for RS-485 so no manual flow control is needed. A compact IP30 desktop design with operation from 0 to 60 C makes it a practical choice for extending serial runs in control cabinets, labs and equipment rooms.

Features

FAQs

Q: Does the Moxa TCC-80I need an external power adapter?
A: No. The TCC-80I is port-powered and draws its power from the RS-232 port, so no external power supply is required.

Q: What is the difference between the TCC-80I and the TCC-80?
A: The TCC-80I adds 2.5 kV isolation and an LED port power indicator that shows whether the unit is receiving enough power from the host port.

Q: Which RS-485 and RS-422 wiring modes does it support?
A: It supports 2-wire half-duplex RS-485 and 4-wire full-duplex RS-422/485.

Q: Do I need to manage RS-485 data direction manually?
A: No. The converter provides automatic data direction control for RS-485, enabling the driver when TxD output is sensed.

Q: What operating conditions is the TCC-80I rated for?
A: It operates from 0 to 60 C and has an IP30 rating, intended for desktop use in controlled indoor environments.
