RxD, RD, or S
in
Receive data, or signal in.
TCD Thermal conductivity detector. A detector that uses the thermal
conductivity of the different gas components to produce an
unbalanced signal across the bridge of the preamplifier. The higher
the temperature, the lower the resistance on the detectors.
TxD, TD, or S
out
Transmit data, or signal out.
