Moxa TCC 80 media converter provides complete signal conversion between RS232 and RS422/485, without requiring an external power source. The converter support both half duplex 2-wire RS485 and full duplex 4-wire RS422/485, and can be converted between RS232’s TxD and RxD lines. In addition,the TCC 80’s 15 kV ESD protection guards against damage from electrostatic discharge. Automatic data direction control is provided for RS485. In this case, the RS485 driver is enabled automatically when the circuitry senses the TxD output from the RS232 signal. This means that no programming effort is required to control the transmission direction of the RS485 signal. The RS232 port of the TCC 80 is a DB9 female socket that can connect directly to the host PC, with power drawn from the TxD line. Regardless of whether the signal is high or low, the TCC-80 MOXA can obtain enough power from the data line. However, external power can be used if the handshake line is not available, if the serial cable is too long, or if the RS232 device is a low power device. For external power, a 5 to 12 VDC power supply can be connected using an adaptor or a USB power cord. When installing a TCC-80, it is important to pay attention to power consumption, RS232 cable length, and RS422/485 transmission distance. In general, the TCC-80 obtain 50 mW of power from the power source. Standard PC COM ports can provide 70 to 90 mW of power if the TxD, RTS, and DTR lines are connected. Moreover, the RS232 cable should be shorter than 15 m (@ 9600 bps) to ensure that less power is lost from the host/device to the TCC-80. The remainder of the supplied power is used for transmitting the RS422/485 signal. It’s easy enough to test the serial device with a multimeter to determine that the serial device will provide enough power to the media converter.
