1Introduction
The Indigo range comprises four frame types: 4U frames for up to 24 modules, 2U frames
for up to 12 modules, 1U frames for up to six modules and 1U desk top boxes for up to
two modules.
There are two 4U frame variants - passive front panel and a Statesman enabled version
with Ethernet capability.
This manual covers:
Indigo 4 with passive front panel
Indigo 4SE Ethernet capable Statesman enabled with active panel, no controls or display.
The frames provide configurable rear connections and the facility for a maximum of three
separate plug-in power supplies. This allows a dual supply facility for redundancy and
continued operation in the event of a power supply failure. A hinged front panel and
removable fan assembly provides access to the power supply unit and all of the modules.
The Crystal Vision Indigo 4 frame with front control panel open

Crystal Vision Introduction
Indigo 4 User Manual R1.7 4 09/08/2012
There are four easily accessible front fans. Two are fitted on detachable plates in front of
the PSU modules and the other two are attached to the rear of the front panel.
On opening the front panel an optical sensor switches the PSU fans to fast operation and
the panel mounted fans are stopped by removing their power.
If one fan fails, or operates too slowly, the other fans are automatically switched to full
power and an alarm raised.
The frame internal temperature is monitored by sensors mounted at the rear of the upper
and lower middle bays, the fans speed is adjusted to maintain an optimum operating
temperature over a wide range of load and ambient temperatures.
There are three cooling modes: normal, quiet and maximum.
With normal cooling all fans run continuously, increasing in speed as the temperature
inside the frame goes up.
Quiet mode is intended for a lightly loaded frame in an environment where ambient noise
is a concern. When the frame temperature is below approximately 45°C the panel fans are
switched off and the PSU fans runs at minimum speed. If the frame temperature goes
above 45°C it reverts to normal cooling and goes back to quiet mode when the frame
temperature again falls below 42°C.
In Maximum cooling mode all four 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.
Only one fan in each of the upper and lower frames 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 °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.
All Indigo PSU modules have a built in processor, this processor (referred to as a PIC)
communicates with the front panel processor to pass on status information such as power
rail voltage levels (+5.75V and -6.0 V) and the PSU fan speed.
The panel processor regularly receives status updates from the PSU processors about
power rails and fan speed. This allows the front panel to update its status LEDs and
control the alarm changeover relay. The relay contacts are available on Remotes 2 and 8
connectors on the rear of the frame. If third and fourth PSUs are fitted, any alarms will
appear on Remotes 4 and 6.
There are ten two-colour LEDs on the front panel, with yellow/green indicating a normal
condition and red an abnormal condition. An eleventh LED indicates external comms
activity.

Crystal Vision Introduction
Indigo 4 User Manual R1.7 5 09/08/2012
Ten of the LEDs show the status of the front fan, PSU fan, upper power supply, lower
power supply and frame temperature. If a PSU is not fitted, the corresponding LED will
not illuminate.
A Comms LED monitors external RS422 activity and will flash amber when there is
external communications with the frame.
Statesman users will be able to remotely monitor frame temperature and fan speed.

Power supply relay connections
Each power supply module has a changeover relay to indicate if the frame is in an alarm
state caused by a power supply problem, a fan stopping or an overheating frame.
Pinout is as follows:
Upper Power Supply (PSU 2) Relay Connections
Description pin number
relay common Remote 2 pin 14
open on fault Remote 2 pin 23
close on fault Remote 2 pin 5
Power Supply (PSU 4) Relay Connections
Description pin number

close on fault Remote 6 pin 5
Lower Power Supply (PSU 1) Relay Connections
Description pin number
relay common Remote 8 pin 14
open on fault Remote 8 pin 23
close on fault Remote 8 pin 5
The PSU alarm relays are grouped in two groups. PSU1 and PSU3 relays act together and
similarly PSU2 and PSU4 relays act together. Should an error occur in the top half of the
frame, say a front panel fan failure or PSU failure, assuming all PSUs are fitted, both
relays situated in that half of the frame will go to the alarm state. Note there may be a
delay between the relays changing state depending on the type of error. This is because
the relay can be controlled both locally by the PSU and by being asserted by the front
panel which could rely on the front panel completing a poll before initialising the alarm.
The failure of any one mains inlet will result in all PSU relays indicating an alarm.
Note: The current through the relay contacts should be limited to a maximum of 200mA.

Note: TX and RX are defined on the boards. This connector can be used to connect a REMIND remote
control panel. If an external RS422 control device is to be used ensure that the controller will drive
the RX+ with TX+ etc.
Note: Since the 422 Bus Output connector has no GND pin, two frames or other pieces of equipment
which make a connection from the 422 Bus Output should ensure the GND of the two frames are
connected together. This will normally occur through the earth pin on the mains connector.

2.3 Terminating the RS422 Statesman chain
The RS422 communication chain used for Statesman should be terminated when a frame
is the last device in a chain or when a frame is the only device. It is unterminated for all
other applications including when frames are used with a Statesman Hub.
To change the RS422 communications termination access the RS422 term/unterm switch
at the bottom of the lower front control panel PCB by opening the panel and lifting it
upwards.

serial 422 connected systems. In a TCP system the frame address switch must be set to
zero.
Rotary switch Position Description
Frame Address Normally zero This is usually the address of the frame from 0 to 15.
Note: Set this switch to position 0, unless multiple frames communicate with a single PC port
in a Statesman system, or if multiple control panels connect to a single frame via one
multi-drop cable.
Statesman will display the Hex switch settings 0 to E as frame addresses 1 to F. Switch
setting F will be displayed as frame address 10.
Status LEDs
These LEDs are useful for trouble shooting 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 data LED flashing
will indicate that communications between the frame and the network exists.

address Normally up. Down sets IP address to default 10.0.0.201.
Note: Quiet mode is dependent on PSU and PSU fans not being in an alarm state.
If one of the fans should fail, the closed frame can still operate indefinitely with an
ambient temperature of up to 40°C.
Although only one of the fans is essential in normal operation a faulty fan should be
replaced as soon as practical to prevent the long-term stressing of the modules.
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.
Switch 3 is for debug purposes and should normally be left in the up position.
Default IP address
Switch 4 in the down position sets the active front panel to the default IP address of
10.0.0.201. This default address is necessary to be able to change the IP address during
installation.
PSU Configuration
PSU configuration only applies to the 2U and 4U frames where it is possible to have
multiple power supplies fitted into a single frame. Should a power supply not be fitted in
either the upper or lower slots of the 2U frame or the upper or lower slots of the lower
section of the 4U frame the position of the two-position slide switch must be set
accordingly.

Crystal Vision Installation
Indigo 4 User Manual R1.7 18 09/08/2012
If both power supplies are fitted the slide switch is set to position two. If the switch is set
to one 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 to one instead of
two. Should only a single supply be fitted with the switch set to Two a power supply fault
will be registered.
2.6 Setting up and connecting
The frame can be connected to a network port or directly to a PC from the rear panel RJ45
port labelled Ethernet. If connecting directly to a PC a CAT-5 cross over cable will be
required. Connecting to a network port hub uses a straight CAT-5 cable.
Changing the IP Address
An Ethernet enabled frame will need to have its IP address set upon installation. This is
made possible by setting the frame to act as a web server and then accessing an internal
web page. Any software upgrades can also be downloaded to the frame via this web page.
To access the internal web page set the frame to the default IP address by setting the
default IP address switch to down or to the left for the 1U front. Open up your PC web
browser and set its search to http://10.0.0.201 and select ‘go to’. This is the default IP
address, the sub-mask being 255.255.255.0. After a dialogue box has briefly appeared the
Indigo main status page will be displayed. This page will give a large amount of status
information about the frame and its power supplies.
From this web page you are able then to change the IP address manually or automatically
