I
Receiver 5 – Positive Data Differential Input from Line
The XRT4500 will accept either a V.10, V.11 or V.28 type signal via
this input pin, along with RX5A (Pin 36) and will generate a result-
ing CMOS level binary data stream, via the RX5D (Pin 33) output
pin. The exact function of this input pin depends upon whether the
XRT4500 device is operating in the DTE or DCE mode.
DTE Mode
– Positive polarity portion of the DSR line signal.
DCE Mode
– Positive polarity portion of the DTR line signal.
Note:
This output pin is not used if the XRT4500 has been con-
figured to operate in either the V28/EIA-232 or V10 Modes.

Receiver 5 – Negative Data Differential Input from Line
The XRT4500 will accept either a V.10, V.11 or V.28 type signal
via this input pin, along with RX5B (pin 35) and will generate a
resulting CMOS level binary data stream, via the RX5D (Pin 33)
output pin. The exact function of this input pin depends upon
whether the XRT4500 device is operating in the DTE or DCE
mode.
DTE Mode
– Negative polarity portion of the DSR line signal.
DCE Mode
– Negative polarity portion of the DTR line signal.
Note:
If the XRT4500 has been configured to operate in either
the V28/EIA-232 or V10 Modes, then all of the data will be out-
put (to the line) in a single-rail manner via this output pin.

Receiver 4 – Negative Data Differential Input from Line
The XRT4500 will accept either a V.10, V.11 or V.28 type signal
via this input pin, along with RX4B (pin 38) and will generate a
resulting CMOS level binary data stream, via the RX4D output
pin (Pin 40). The exact function of this input pin depends upon
whether the XRT4500 device is operating in the DTE or DCE
mode.
Note:
If the XRT4500 has been configured to operate in either
the V28/EIA-232 or V10 Modes, then all of the data will be out-
put (to the line) in a single-rail manner via this output pin.
