+
+If both interfaces are enabled using the ``numinterfaces`` command on compatible hardware and firmware, the image splits into top and bottom halves sent over two UDP ports:
+
+   - The top half transmits via the inner interface (``udp_dstport2`` and ``udp_dstip2``).
+
+   - The bottom half uses the outer interface(``udp_dstport`` and ``udp_dstip``).
+
+The number of files per module equals the active UDP ports—two files per module when both interfaces are used.

+The number of image rows per port can be adjusted using the ``readnrows`` command. By default, 400 rows are read, but a smaller value centers the readout vertically (e.g., 16 rows reads 8 above and 8 below the center). Increasing the value symmetrically expands the region toward the top and bottom. Permissible values are multiples of 16.
