Introduction
The TCC-80/80I media converters provide complete signal conversion between RS-232 and RS-422/485, without requiring an external power
source. The converters support both half-duplex 2-wire RS-485 and full-duplex 4-wire RS-422/485, either of which can be converted between RS-
232’s TxD and RxD lines.
Automatic data direction control is provided for RS-485. In this case, the RS-485 driver is enabled automatically when the circuitry senses the TxD
output from the RS-232 signal. This means that no programming effort is required to control the transmission direction of the RS-485 signal.
Port Power over RS-232
The RS-232 port of the TCC-80/80I 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-80/80I 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 RS-232 device is a low-power device. For external power,
a five to twelve VDC power supply can be connected using an adapter
or a USB power cord.
Port Power Dissipation
When installing a TCC-80 or TCC-80I converter, it is important to pay attention to power consumption, RS-232 cable length, and RS-422/485
transmission distance. In general, the TCC-80 and TCC-80I 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 RS-232 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 RS-422/485 signal.

Port Power and Optical Isolation
The RS-232 port of the TCC-80/80I is a DB9 female socket that can
connect directly to the host PC, with power drawn from the TxD line.
Electrical 2.5 kV isolation for the TCC-80I is achieved with a photo
coupler that transforms the electrical signal into light, and then re-
transforms the light back into an electrical signal on the other side. In
this way, the two electrical circuits are completely isolated from each
other. This also protects the devices from ground loop currents,
reduces damage caused by data loss, and prevents damage to the
communication interfaces.
LED Port Power Indicator
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. However, it’s even easier to let the TCC-80I test the
device for you. Simply connect the TCC-80I to the device’s RS-232
port and set the SW4 switch to Test mode. If the port power LED
indicator lights up, the TCC-80I is receiving enough power. If the LED
does not light up, you will need to attach an external power source to
the TCC-80I.
