Overcurrent protection

The Moxa TCC-80-DB9 is a compact media converter that enables signal conversion from RS-232 to RS-422 or RS-485 (in 2- or 4-wire topology). It is designed for industrial applications requiring simple handling, space-saving, and operation without an external power supply. The device is powered via the RS-232 interface (TxD or RTS/DTR), allowing flexible integration into existing systems. Alternatively, it can be powered via a USB cable or an external power supply with 5 to 12 VDC. The power consumption is 30 mA, ensuring efficient energy use. An integrated LED indicator signals whether sufficient port power is being supplied via the RS-232 interface.

Applications
This converter is particularly suitable for industrial environments where serial communication over long distances is required, such as in automation technology, machine control, or building automation. Support for RS-422 and RS-485 enables reliable data transmission over longer distances and in noisy environments. The compact design and desktop mounting facilitate installation in confined spaces or on control desks.

Functions and Features in Detail
The TCC-80-DB9 features two serial ports that can be configured as RS-232, RS-422, or RS-485 (2- or 4-wire) depending on requirements. The signals include TxD, RxD, GND for RS-232, Tx+/-, Rx+/-, GND for RS-422, and Data+/-, GND for RS-485-2w, as well as Tx+/-, Rx+/-, GND for RS-485-4w. An integrated DIP switch enables optional termination with 120 Ohm, which is important for optimal signal transmission in RS-485 networks. Automatic baud rate detection (300 bps to 115.2 kbps) and automatic data direction control (ADDC) reduce configuration effort and enhance user-friendliness.

Technology Explained Simply
Signal conversion occurs without an external power supply, allowing the converter to operate independently of additional power adapters. Power supply is either via the RS-232 interface (TxD or RTS/DTR) or via an external USB cable. The input voltage ranges from 5 to 12 VDC. Power consumption is 30 mA, representing a low load on the power source. An overcurrent protection safeguards the device against damage from excessive current draw. The IP30 protection rating ensures protection against solid foreign objects and splashing water, but not against dust or prolonged moisture. The housing consists of plastic on top and metal on the bottom, providing a robust yet lightweight construction.

Compatibility and Accessories
The converter is compatible with RS-232, RS-422, and RS-485 protocols and can be integrated into existing serial networks. The DB9 connector (male) allows direct connection to standard PC interfaces or industrial devices. Automatic baud rate detection and ADDC functionality simplify communication with various devices. The device is designed for operating temperatures from 0 to 60 °C and can be operated at humidity levels from 5 to 95 % (non-condensing). Storage is possible from -20 to 75 °C.

Mounting and Installation
Mounting is done as a desktop device, requiring no special fixation. The DB9 connector enables quick and secure connection. Power supply is either via the RS-232 interface or via the included USB power cable. Configuration is done via the integrated DIP switch for termination settings. The quick start guide included in the package supports setup.

Operational Advantages
The TCC-80-DB9 offers reliable signal conversion without an external power supply, simplifying installation and reducing operating costs. Automatic functions such as baud rate detection and ADDC reduce configuration time. The integrated termination option and LED indicator for port power enhance operational safety. The robust construction and certifications according to EN 55032/35, CISPR 32, FCC Part 15B, IEC 61000-4-x, and UL 60950-1 ensure safe and interference-free operation. The high MTBF of 2,781,161 hours (Telcordia) underscores the device's longevity.

Scope of Delivery
The scope of delivery includes 1x TCC-80-DB9 converter, 1x USB power cable (50 cm), 1x quick start guide, and 1x warranty card.
