Crystal Vision Introduction
1 Introduction
The Indigo 2AE and 2SE frames are 2U Ethernet enabled frames for up to 12 modules. The
2AE has an integrated front control panel with display; the 2SE has no integrated front control
panel but has additional cooling and is designated the ‘Indigo 2SE CoolFlow’.
There are configurable rear connectors and space for up to two plug-in power supplies. The
dual supply facility allows for redundancy and continued operation in the event of a power
supply failure.
All models have a hinged front panel that allows easy access to removable fan assemblies,
power supplies and modules.
The Indigo 2AE frame with front control panel open
The Indigo 2SE Coolflow front panel.
On the 2SE there are three easily accessible fans. One is fitted on a detachable plate in front of
the PSUs and the other two are attached to the rear of the front panel. The frame can be
operated with the front panel open, with an optical sensor on the front panel switching the PSU
fan on and the front panel fans off. The PSU fan only runs when the frame is open. If one of the
front panel fans should fail or operate too slowly, the other front panel fan is automatically
switched to full power and an alarm asserted. A frame temperature sensor mounted above the
top central module position (slot 5) also controls fan speed. There are two cooling modes:
automatic and maximum. With automatic cooling both front panel fans run continuously,
increasing in speed as the temperature inside the frame goes up. In maximum cooling mode
both front panel fans are set to maximum speed. This mode is ideal for equipment bays where
noise is not a concern.
On the 2AE there are two easily accessible fans. One is fitted on a detachable plate in front of
the PSUs and the other is attached to the rear of the front panel. Only one of the fans is
essential in normal operation. If one of the fans should fail, the closed frame can still operate
indefinitely with an ambient temperature of 40 degrees. A frame temperature sensor mounted
Indigo 2AE and 2SE User Manual R1.17 4 27 February 2020

Crystal Vision Introduction
above the top central module position (slot 5) also controls fan speed. There are three cooling
modes: quiet, normal and maximum. In normal operation both fans operate at reduced power to
keep the unit cool but quiet. If the front panel is opened an optical sensor switches the PSU fan
to fast operation and the panel fan off. A wire on the fan gives a reliable indication of its speed
and if it fails or operates to slowly the other fan is automatically switched to full power and an
alarm raised. Quiet mode is used with a lightly loaded frame with a low ambient temperature:
where the frame temperature is below 450C the panel fan is switched off and the PSU fan runs
at minimum speed.
Warning: Although it is possible to operate the frame with the front panel open, the frame
may not meet electromagnetic compatibility (EMC) requirements in this condition.
The Indigo PSUs have a built-in processor, which communicates with the front panel display
processor (referred to as a PIC) and monitors power rail voltage levels (+5.75V and -6.0 V). The
PSUs also store their own serial number in non-volatile memory.
The panel processor regularly receives status updates from the PSU processors about power
rails. This allows the front panel to update its status LEDs and control the alarm changeover
relay. The relay contacts are available on the Remote 2/4 connector on the rear of the frame.
There are five two-colour LEDs on a front panel, with green indicating a normal condition and
red an abnormal condition. If the LED is unlit, this indicates an inactive condition such as a
single PSU fitted or PSU fan not running with the front panel closed.

2.4 Configuration Switches
The Indigo 2AE and Indigo 2SE CoolFlow frames both make use of a 6-way DIL configuration
switch mounted on the front panel CPU board to change the hardware configuration. The DIL
switch functions are identical for both frame types although the CPU boards are different.
Indigo 2AE
On the upper edge of the Indigo 2AE front panel PCB, the 6-way DIL configuration switches and
reset switch can be found. This PCB was fitted early 2015 – see Appendix 3 for older frames.
Indigo 2AE CPU board.
‘Reset’ switch on side of board
Indigo 2SE CoolFlow
The CPU board is mounted on the rear of the front panel. This PCB was fitted after August
2013 – see Appendix 3 for older frames. Also on this board is a status ‘Link’ LED. This LED is
useful for troubleshooting the network link. The link LED will be illuminated whenever the frame
is connected to a network. Should this LED not be lit, check the cable connection between the
frame and network outlet. The ‘Term’ switch terminates the RS422 chain which was used by
older pre-Ethernet enabled frames and is no longer supported by Crystal Vision.

Cooling mode
Switches 1 and 2 of the four-position DIL switch control the three cooling modes - normal, quiet
and maximum - as follows:
Switch 1 & 2
Function
Notes
Both up Normal cooling Both fans run continuously increasing in speed as
the temperature inside the frame goes up.
1 down, 2 up Quiet mode For use with a lightly loaded frame for low ambient
temperature. When the frame temperature is below
approximately 45°C the panel fan is switched off
and the PSU fan runs at minimum speed. If the
frame temperature goes above 45°C it reverts to
normal cooling and goes back to quiet mode when
frame temperature falls below 42°C.
1 up, 2 down Maximum
cooling mode In Maximum cooling mode both fans never run below near maximum speed. Fan speed increases
to maximum at high frame temperature. This mode
is ideal for equipment bays where noise is not a
concern.
Both down Reserved for
future use Operates as normal mode with current software.
Note: Quiet mode is dependent on PSUs and PSU fans not being in an alarm state.
For the Indigo 2SE only one of the fans is essential in normal operation and if
one of the fans should fail, the closed frame can still operate indefinitely with an
ambient temperature of 40°C.
Warning: Although it is possible to operate the frame with the front panel open, the frame
may not meet electromagnetic compatibility (EMC) requirements in this
condition.
Indigo 2AE and 2SE User Manual R1.17 12 27 February 2020

Crystal Vision Installation
PSU Configuration
If a power supply is not fitted in either the upper or lower slots, the position of configuration switch
4 on the top right of the front panel PCB must be set down. If both power supplies are fitted,
switch 4 is set up. If the switch is set down and there are two power supplies fitted, the LOWER
PSU LED will flash from GREEN to OFF every two to three seconds to warn that the switch is set
incorrectly.
Address Range
The slot address range switch was used when two frames were paired together to make one
large frame with 24 slots. As this practice is no longer used, switch 5 should be left in the up
position.
Default IP address
Switch 6 in the down position sets the active front panel into recovery mode with the default IP
address of 10.0.0.201. Recovery mode enables frame firmware updates and also forces the
frame to accept network communications at address 10.0.0.201. Should the frame’s IP address
be unknown, then forcing to the default address will allow access by a web browser whereby the
network settings may be changed.
See section Control for more information on establishing an Ethernet connection with a frame.
Reset switch
Press this switch to reset the CPU following a software upgrade or when resetting the IP
address to its default value.
2.6 Connector pin out
Remote Control / GPI Connections
Each frame slot has six connections that are brought out to one or more of the four high density
D-Type connectors on the rear of the frame labelled Remote 1 to 4. These connections are
referred to as lines 'a' to 'f'. The functions assigned to them are dependent on the module
inserted in each slot, but a typical use is as a GPI line. Refer to the documentation supplied with
each Crystal Vision module to determine the actual functions assigned.

A faulty condition is indicated when the corresponding LED is red and a normal condition when it
is green. If only one PSU is fitted, the corresponding LED will be unlit.
The status of the PSUs can also be investigated using VisionWeb control, the VisionPanel
control panels, Statesman Lite PC control, as well as the Indigo 2AE integrated control panel as
shown in the section Operating the Active Panel.
Configuring PSUs
The number of fitted PSUs must agree with the configuration switch settings – see section
PSU Configuration.
