2.4.7 IPN250RTM Interface Connector (P1)
This socket connects to J10 on the IPN250RTMA.
2.4.8 COM1 Connector (P3)
The IPN250 supports front or rear COM port connection, but only one set of
connectors can be active at a time. The IPN250RTM provides rear connection via a
standard 9 ‐ way sub ‐ miniature male D ‐ type connector P3 and also via a 2x5 way
header on the PCB P5 (see Section 2.4.10 ʺ COM2 Connector (P5) ʺ ).
The following table gives RS232 and RS422/485 versions of the available signals.
Figure 2-4 IPN250RTMB P3 Pin Numbering

with 9 ‐ way socket connectors.
2.4.9 Audio Header (P4)
The IPN250 supports a stereo pair (left and right) of audio inputs and a stereo pair
(left and right) of audio outputs. Signal names (input/output) are with respect to
the IPN250.
