Port Power and Optical Isolation
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.
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.
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 patented 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.
