SURFACE COMPONENTS

There are a range of components
within the surface. This section
explains how these components
are connected, receive power and
communicate with each another.

UN6539 Section Processor

The Section Processor as shown on
fig 1 (front) and Fig 2 (rear) on the next
page, connects to all the surface section
elements fitted in the specified console.
The section processor unit is designed
to be housed in a ventilated enclosure
under the upper surface at the rear of the
console as shown in Fig 3 on the next
page and has the following features:-

Gigabit Ethernet Ports:

• Rear facing (external), see Fig 2.
• 2 x GBE stacked ports on RJ45 for
connectivity to Core Processing unit (e.g.
Impulse core)
• Will connect to Ethernet switches
housed in the rear of the console or at
remote location.
• Redundancy is provided by two Ethernet
ports
• Identical function and performance is
provided on both ports
• Section Processor may connect to the
Impulse Cores via either port
• LEDs for connectivity and activity status
are supported for each GBE port.

Video Input/Output Interfaces:

• Rear facing (external), see Fig 2.
• Provides two transport and protocol
agnostic video I/O interfaces.
• 2 x SFP+ compatible cages are
provided; horizontally side by side.
• MSA compliant and SFP+ modules are
supported.
• An MSA compliant port supports
Transceiver, Single Transmitter or Single
Receiver SFP with SDI host interface.
• These ports support 10 Gigabit
SFP+ modules for native video over IP
encapsulation / de-encapsulation.
• Video Conversion & Scaling of third
party video input at minimum 1080p.
• Video output is available at 1080p.
• Access to control and status MSA
pinouts provided to give module flexibility
in support of all MSA SFP/SFP+ devices.
• LEDs for status indication via FW/SW.

Display Modules:

• Front facing (internal), see Fig 1.
• The Section Processor provides two
Display Port interfaces to display rendered
graphics and composited video on both
the Meter and Touchscreen Display
Modules for:-
• Console GUI.
• Rendered Bar Graphs.
• Input Video.
• 2 x DP Display Port 1.4 interfaces.
• Cable length 2m; possibly more at the
data rates used by this system; below
maximum of DP standard.
• The Section Processor has 2 x full-size
DP latching connectors.
• System uses standard low-cost fully
screened DP cable between Section
Processor and each Display Module.
• HPD sense and AUX channels are
supported as key requirements of the
standard.
• Display backlight level and enable
control provided as baseband signalling
over unused DP pairs.
•Non-compliant mode to be engaged only
if EDID matches TFT for Display Module.
• Open-drain signalling to prevent
damage to 3rd party equipment if non-
compliant mode is inadvertently enabled.
• Display Port Dual-Mode (DP++)/Dual-
Mode Display Port is

not

supported.

• A USB 2.0 connector which is dedicated
to the touch digitiser in the Touchscreen
Display Module is provided.

Controller Surface Modules:

• Front facing (internal), see Fig 1.
• 3 x USB 3.0 Type A connectors which
connect to the Surface Controller fitted in
the Control Surface Modules.
• Proprietary use of USB 3.0 interface
is implemented for use with the Control
Surface Modules only
• 2 x LVDS outputs on each USB 3.0
port for Mini-TFT data to Control Surface
Modules are provided.
• LVDS transports clock & video data over
SuperSpeed pairs on the USB 3.0 port.
• The USB 2.0 legacy pair in the USB
3.0 connector transports surface control
events between panels and host processor.
• Surface reset via Control Surface
Module, implemented as base band signal
on USB 3.0 cable

User USB Inputs:

• Front facing (internal), see Fig 1.
• 2 x USB 2.0 to front-facing USB Type-A
Panel connectors are provided for:-
• Keyboard, mouse or file transfer when
connected to USB 2.0 port Type-B
connector on Monitor panel.

USB Misc Inputs:

• Rear facing (external), see Fig 2.
• 2 x USB 2.0 connectors to rear-facing
USB Type-A connectors are provided for
general-purpose USB functions
• Used for Recovery boot, development
communications & service access.

Surface USB Switch Output:

• Rear facing (external), see Fig 2.
• Amalgamated Touchscreen and User
USB connectivity may also be routed to
rear panel USB 2.0 Type B Touch Output
port for direct control of an external third-
party system.
• This is Intended to be used with video
input to provide in-surface control of 3rd
party equipment.

Configuration IP Set/HW ID/Switches:

• Rear facing (external), see Fig 2.
• A 10 way binary switch is available with
MSB on the left & each switch ON when
in the "UP" position. It is used to set an
IP address or select features as required.

DC Power distribution:

• Front facing (internal), see Fig 1.
• The Section Processor has a pair of
red12V inlets from power supply.
• The Section Processor provides six
se12V DC power over six 4-way
cables to supply:
• Control Surface Modules (x3).
• Display Modules (x2).
• I/O Board or Ethernet switch (x1)
• Provision for independent SW control of
power ports is made.
• Power sequencing to spread inrush
loading is implemented.

Reset Switch:

• Rear facing (external), see Fig 2.
• The Section Processor provides a
momentary action Reset switch for
manual reset on the rear panel next to the
2x GB Ethernet ports stack.
