38 Chapter 4: Matrox Rapixo CXP hardware reference
outlines the bit rates that you can expect to achieve at certain lengths, using Belden
1694A cables, as well as the bit rates possible when connecting to a single video
source using link aggregation (2, 3, and 4 cables).
Effect of the type of
PCIe slot
A PCIe 3.x slot supports a higher data transmission rate than a 2.x slot. The
Quad CXP-12 requires a 3.x slot; a x4 PCIe slot will lower the data rate by half,
when compared to a x8 PCIe slot of the same base specification (3.x or 2.x). While
transferring data to the Host, these factors will reduce the maximum transmission
rate as follows.
Power-over-CoaXPress
Matrox Rapixo CXP supports power-over-CoaXPress (PoCXP) compliant video
sources, and non-PoCXP compliant video sources. If Matrox Rapixo CXP is
connected to the computer’s power supply cable that has a 6-pin, compatible,
mating 12 V connector, the board can provide up to 13 W per connection, at a
nominal voltage of 24 V, to the devices connected to the CoaXPress input
connectors.
Matrox Rapixo CXP detects whether the video source is PoCXP-compliant. When
connecting to non-PoCXP compliant video sources, Matrox Rapixo CXP has
appropriate circuitry to ensure that no power is transmitted. To manually disable
the PoCXP circuitry and ensure that no power is sent to the device, you can use
the MIL-Lite function
MdigControl()
with
M_POWER_OVER_CABLE
