TYPE FUNCTION
O Transmitter 1 – Negative Data Differential Output to Line
The exact function of this output pin depends upon whether the
XRT4500 is operating in the DCE or DTE Modes.
DTE Mode: Transmit Data (TXD) – Negative Polarity Output
Signal
Transmitter 1 accepts a TTL level binary data stream (as the
“Transmit Data” – TXD) from the DTE Terminal Equipment. Trans-
mitter 1 converts this digital data into any of the following electrical
formats: V.10, V.11, V.28 and V.35 prior to transmission to the line.
If this data is being converted into either the V.11 or V.35 format,
then this pin outputs the negative-polarity portion of the “TXD”
data to the line. If this data is being converted into either the V.10
or V.28 formats, then this pin outputs this data to the line in a sin-
gle-ended manner.
DCE Mode: Receive Data (RXD) – Negative Polarity Output
Line Signal
Transmitter 1 accepts a TTL level binary data stream (as the
“Receive Data” – RXD) from the DCE Terminal Equipment.
Transmitter 1 converts this digital data into any of the following
electrical formats: V.10, V.11, V.28 and V.35 prior to transmission
to the line.
If this data is being converted into either the V.11 or V.35 format,
then this pin outputs the negative-polarity portion of the “RXD”
data to the line. If this data is being converted into either the V.10
or V.28 formats, then this pin outputs this data to the line in a sin-
gle-ended manner.
