2.2 DVI/HDMI Selection
The GPU on the IPN250 supports both DVI and HDMI output. The IPN250RTM
incorporates a switch to route these two signalling types to the appropriate
connectors ‐ see P7 Switch 3, Section 3.1.1 ʺ Miscellaneous Signals ʺ . Only one type
of signalling can be output at one time.
Switch P7/position 3 controls selection: OPEN=HDMI.
The HDMI/DVI selection process also ensures the following routings:
• The appropriate Hot Plug Detect signals from the active connector to the
GPU
• The appropriate DDC signals (including the +5V DDC supply) between the
active connector and the GPU
2.3 IPN250RTMA
2.3.1 1000BaseT Ethernet Channel 1/2 Connector (J3)
The IPN250RTM supports two thin pipes on the Control Plane, as defined by the
OpenVPX Payload Slot Profile SLT6 ‐ PAY ‐ 4F1Q2UT2T ‐ 10.2.1. These pipes are
brought out to a dual (side by side) RJ45 ‐ type connector, pinned out to the
TIA/EIA 568 standard.
The signal pairs are 100

differential and matched.
GEIP offers cable C ‐ CBL000122 ‐ 001, which is a 2m long Cat5E Ethernet patch
cable with RJ45 connectors.
