Frequently Asked Questions - TCC-80I-RP Moxa

How do I connect the TCC-80I-RP to my serial device and fiber optic cable?

Connect your serial device to the DB9 female connector on the converter. Set the DIP switches for RS-232, RS-422, or RS-485 as needed. Connect the fiber optic cables to the ST ports (TX and RX) using multi-mode fiber. Ensure power is connected to the terminal block.

What is the maximum transmission distance with multi-mode fiber?

The TCC-80I-RP can transmit data up to 2 km over multi-mode fiber with a 62.5/125 μm or 50/125 μm core.

How do I configure the DIP switches for RS-485?

For RS-485, set DIP switches 1 and 2 to ON (RS-485 2-wire) or OFF/ON (RS-485 4-wire). Refer to the DIP switch table on the device label for exact settings. Enable termination resistors if the device is at the end of the bus.

What do the LED indicators mean?

The front panel has LEDs: PWR (green) for power, TX (amber) blinks when data is transmitted, and RX (amber) blinks when data is received. If both TX and RX are solid, check fiber connections.

What power supply should I use?

Use a DC power supply with output between 12 and 48 VDC and at least 300 mA capacity. Connect to the terminal block with positive to V+ and negative to V-. The device has reverse polarity protection.

Can I use single-mode fiber with this converter?

No, the TCC-80I-RP is designed for multi-mode fiber only. For single-mode fiber, use a different Moxa model such as TCF-142-S.

Does it support RS-485 termination and bias resistors?

Yes, the TCC-80I-RP has built-in 120 ohm termination resistors and bias resistors that can be enabled via DIP switch 3 (termination) and switch 4 (bias). Enable them if the converter is at the end of the RS-485 line.

How do I mount the device on a DIN rail?

Attach the DIN-rail clip (included) to the back of the unit using screws. Then clip the unit onto a standard 35 mm DIN rail. Ensure it clicks securely into place.

What is the operating temperature range?

The TCC-80I-RP operates reliably in temperatures from -10 to 60°C (14 to 140°F) with humidity up to 95% non-condensing.

Can I power the device with 5V USB?

No, the required input voltage is 12 to 48 VDC. 5V is too low and will not power the device correctly. Use a suitable industrial power supply.

Isolated High-Speed Serial Port Powered Serial Media Conversion Solution

TCC-80I / TCC-80I-DB9

First high-speed, isolated, self-powered RS-232 to RS-422, 2-wire/4-wire RS-485 bi-directional converter with 2.5 KV isolation and 15 KV ESD protection.

Overview

The TCC-80I is the world's first high-speed, isolated, self-powered converter. It is powered through the host's RS-232 port and provides complete signal conversion between RS-232 and RS-422/485 devices. The TCC-80I coverts back and forth between RS-232's TxD and RxD lines to either half duplex 2-wire RS-485 or the balanced signal of full duplex 4-wire RS-422/485. In addition, the TCC-80I provides comprehensive 15 KV LSD protection for all serial lines. Perhaps the most important feature is the 2.5 KV isolation designed to prevent ground loop currents, reduce damage caused by data loss, and prevent damage to the communication interfaces. The TCC-80I is also designed to provide RS-485 auto data direction control, in which the RS-485 driver is enabled automatically when the circuitry senses the TxD output from the RS-232 signal. Programming effort is not required to control the transmission direction of the half duplex RS-485 signal.

Installation

Serial (RS-232) Port Power

The RS-232 port of TCC-80I is designed with a female DB9 socket to connect directly to the host PC, with power drawn from the TxD. RTS, or DTR lines. TCC-80I is capable of taking enough power from the attached Tx line only. For those attached serial RS-232 devices which does not provide enough power on its Tx line, additional handshake lines should be connected to TCC-80I. The DC jack of TCC-80I is also provided for connecting a 5 to 12 VDC power supply via a USB power cord or external power adaptor.

Port Power Dissipation

When installing an RS-232 port-powered TCC-80I converter, pay attention to the power consumption, RS-232 cable length, power provided by the serial port, and the RS-422/485 transmission distance. In general, TCC-80I itself derives 70 mW from the power source; a standard COM port on a host PC can provide 70 to 90 mW of power if the TxD, RTS, and DTR lines are connected. Moreover, the RS-232 cable length should be shorter than 15 m (€ 9600 bps) to ensure that less power is lost from the host/device to the TCC-80L.

Serial Port Power Compatibility

Serial ports use a diversity of interface chips, but the power provided by the different ports is not always the same. In fact, some of the ports do not provide enough power to activate the TCC-80I. The on-board COM1 and COM2 ports seldom have problems. The table shows the add-on cards and the serial-to-Ethernet device servers that have been tested as a good power source to drive the TCC-80I.

LED Port Power Indicator

The best way to ensure the attached serial port provides enough electricity to the TCC-80I is to check the power indicator LED at the front panel. To do this, connect the TCC-80I to the target RS-232 port, and then turn the SW4 switch to the right side to the "Test" mode. The TCC-80I is receiving enough power if the LED lights up after activating the attached serial device. If the LED does NOT light up, you will need to attach the external power cord to the TCC-80I.

Note: Be sure to turn the SW4 switch back to Std. mode (the default) when you finish testing. When in Test mode, the TCC-80I WILL NOT transmit data.

Optional External Power

Termination is a critical requirement for port-power devices such as the TCC-80L. In most circumstances, termination resistors are used when the RS-422/485 cable length is longer than 100 m. Regardless of how much the data signal is dissipated, the termination resistors absorb more than 75 mW of

power from the power source when TCC-80I is unable to use the limited serial power. In other words, if long distance RS-422/485 transmission or termination is required, then an external USB power cord or DC power supply should be used (in this case, DIP SW3 must be ON).

By testing the TCC-80I at different baudrates and transmission distances, we have determined the maximum transmission distance that can be achieved when using serial port power. The test results are shown in the following table.

Baudrate (bps)	RS-422/485 Transmission Distance (m)	Embedded Terminator	External Power Required

Switch and Jumper Settings

To change the operation mode, check the DIP Switch settings on the back panel.
