1 Introduction
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 a desk top box for up to two
modules. There are three frame variants - passive front panel, active panel with controls
and a display or a Statesman enabled version without controls or a display.
There are five desktop box variants - passive front panel, active panel with controls and a
display or a Statesman enabled version without controls or a display. Both the active
panel and Statesman enabled frames are also available with Ethernet capability.
This manual covers:
Indigo DT with passive front panel
Indigo DTA with active panel controls and display
Indigo DTAE Ethernet capable with active panel controls and display
Indigo DTS with active panel, no controls or display. Statesman enabled
Indigo DTSE Ethernet capable with active panel, no controls or display.
The Indigo DTA and DTAE versions also support Statesman.
Each desk top box can be used with any single or double slot rear module in the Crystal
Vision range.
A removable front panel allows easy access to installed modules.
The Indigo DTA/DTAE Crystal Vision desk top box The Indigo DT/DTS/DTSE Crystal Vision desk top box
The DTA version has an active control panel built into it, which may remain forward
facing when removed, allowing panel operation even when the cards are exposed.

Crystal Vision Introduction
Indigo DT User Manual R1.4 4 06/07/2009
Each desk top box has a built in power supply and an internal fan on the right hand side.
There are three cooling modes: normal, quiet and maximum.
With normal cooling the fan runs continuously, increasing in speed as the temperature
inside the frame goes up.
In quiet mode the fan does not run at temperatures below 45 deg C (as measured by the
sensor inside the frame) and always runs at temperatures above 45 deg C. This mode is
ideal where noise is an issue or where the ambient temperature is low.
In maximum cooling mode the fan is always turning at maximum speed. This mode is
ideal for equipment bays where noise is not a concern.
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 DT, Indigo DTA/DTAE and Indigo DTS/DTSE have front panel processors.
These processors monitor the power rail voltage levels (+5.5V and -6.0V) and the fan
speed. Status information is indicated by the state of the FAN, PSU and TEMP LEDs on
the front panel and the alarm relay. The relay contacts are available on the remote 2
connector on the rear of the frame.
There are four two-colour LEDs on the front panel, with yellow/green indicating a normal
condition and red an abnormal condition.
The Indigo DT (passive panel) LEDs
The LEDs show the status of the internal fan, PSU, frame temperature and RS422
activity.
The 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.
Note: The term ‘frame’ and ‘desk top box’ are used interchangeably in this manual.

Indigo DT rear connectors
Connecting mains cables
The desk top box is powered by connecting a power cord to the IEC connector.
Ensure that the power cord has a minimum current rating of 6A fitted with an IEC 320
female connector, includes a protective ground connection and meets relevant local safety
standards.
Note: The fuse holder is part of the mains inlet. The mains cable must be disconnected before
the fuse can be accessed. Replace the fuse only with one of the same type and rating.
Refer to the maintenance section of the trouble shooting guide for more information.
2.4 Connector pinout
Remote control / GPI connections
Each module slot has six connections that are brought out to one or more of the two high
density D-Type connectors on the rear of the frame labelled RMT 1 and RMT 2. 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.

To maintain EMC compliance only good quality screened cable assemblies should be
used.
Power supply relay connections
Fitted inside the unit is a 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:
Description Pin number

8 RX- RS422 – Link bus i/p
Note: These signals are also available on the RMT 2 connector.
Using the RS422 frame link bus
Since the 422 I/O connector has no GND pin, two frames, desk top boxes or other pieces
of equipment, which are linked using this connector, should ensure that the GND of the
two frames are connected together. This will normally occur through the earth pin on the
mains connector.
Terminating the RS422 Statesman chain
The RS422 communication used for Statesman should be terminated when a frame is the
last device in a chain or a 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 top of the front control panel by opening the panel.
Statesman RS422 term/unterm switch
To terminate the Statesman RS422 chain move the switch to the left, to unterminate it
move it to the right.
Note: DT passive panels do not have a Term/Unterm switch and are not fitted with the second
panel PCB (shown at the top in this picture).

2.5 Controlling two frames from one panel
An active control panel or REMIND remote active panel can control up to two frames of
cards by coupling the frame link bus ports of the two frames. The two frames do not need
to be the same type so any combination of Indigo 1, Indigo 2 or Indigo DT can be used.
The only exception to this is the Indigo 4 frame, which cannot be linked to other frames,
as the card count will exceed the maximum. Linking two frames in this way constitutes a
frame pair so one frame must be set to its upper slot address range and the other to its
lower address range. One frame in the pair must be an active frame i. e. have an active
control panel or be Statesman capable, although either frame can be set to be the upper or
lower address.
An important thing to note is that there must be only one active panel to a frame pair i.e.
one active control or Statesman control panel, the second frame must be passive. If the
Indigo REMIND remote control panel is used both frames in the pair must be passive.
Connecting together two active frames will cause the processors to clash and give
erroneous messages.
•A frame pair must consist of one active frame and one passive frame.
•Two passive panels must be used with a REMIND remote panel.
Note: If a frame pair has been established solely for Statesman control, one of the frames can
have a Statesman panel and the other a passive panel.
A passive frame pair can be Statesman controlled via a REMIND control panel.
The two frames can be up to 10m apart depending on cable type and ambient electrical noise.
Setting slot number range
The position of the two-position slide switch labelled Upper / Lower on the top edge of
the main front panel PCB must be placed in the Lower position for one frame and in the

Crystal Vision Installation
Indigo DT User Manual R1.4 11 06/07/2009
Upper position for the other. For example it could be set to Lower position for the Indigo
DTA frame and Upper for an Indigo 1 or Indigo 2 frame.
The number of modules reported to the active display includes the PSUs and front
panel/frame as the Indigo front panel PIC and the power supply have an address and are
treated as modules. Refer to the address range table in chapter 3 'Operating the active
panel' for more information.
The two frames should be connected so that control can pass from one frame to the other
using an RS422 serial link.
Note: The switch will only have an effect the next time the front panel is powered up.
Frame linking configurations
This can be accomplished with a special cable linking the Remote 2 connectors or by
using a standard 4-pair CAT-5 patch cable linking the '422 I/O' connectors.
Using a CAT-5 patch cable
Active-Passive frame pair
A CAT-5 cable (TIA/EIA 568A CAT-5 PATCH) is plugged in the connectors labelled
‘422 I/O’ on each frame.
REMIND-Passive frame pair
This combination will require two CAT-5 cables and a RJ45 splitter/doubler.
Commercially available RJ45 splitter/doubler
Depending on the relationship of the frames to each other the splitter/doubler can be
placed on the rear of the REMIND panel with a CAT-5 cable to each frame, or on the rear
of the first frame so the REMIND and frames can be connected ‘daisy-chain’ fashion.
Frame combinations with Statesman connection
Due to the compact nature of the 1U frame the Statesman and frame link buses share the
same RJ45 rear frame connector. Because of this special care must be taken when making
certain combinations of interconnected frames.

Crystal Vision Installation
Indigo DT User Manual R1.4 12 06/07/2009
There are two main criteria to be considered when linking a number of active frames and
passive frames to a Statesman control system. First, all passive frames must be in
combination with an active frame or panel as a frame pair. Second, only the Statesman
wiring can be ‘daisy-chained’ between active frames. A passive frame will ignore the
Statesman commands but the frame link bus must not be connected across frame pairs due
to processor clashing. This isolation between the Statesman bus and frame link bus can be
achieved by the use of a commercially available RJ45e economiser or adapter cable.
Adapter cable wiring
Commercially available CATe economiser
Using Remote 2 connectors
A special cable is connected between the 'Remote 2' D-Type connectors of the two
frames.
The cable required uses two female 26 way high density D-type sockets. These should be
connected with screened twisted pair cable containing two pairs. All the wiring is pin to
pin. Pins 16 and 7 should use one twisted pair, pins 17 and 25 the other. The screen
should be connected to pin 6 on both connectors.

2.6 Setting frame (desk top box) addresses
The frame address, which only relates to an active or Statesman (non-passive) panel, is
normally set to zero. However unique frame addresses are required in Statesman systems
where multiple frames communicate with a single PC port. The address of a frame pair is
set by its non-passive panel.

Note: Passive panels do not have a frame address switch and are not fitted with the second
panel PCB (shown at the top in this picture).
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
multidrop 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.

2.7 Ethernet control
The Indigo DTAE and DTSE series of 1U desk top boxes are provided with Ethernet
control. This allows the Statesman PC control system or remote active control panels to
control a large number of the Indigo Ethernet series frames over a local area network.

Frame Address
The frame address, which only relates to active panels such as the Statesman enabled or
active control panel, is set to give a frame or frame pair a unique address when used in a
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.
Description
Data Flashing This LED will flash to indicate activity.
Link Normally lit This LED will be lit whenever the frame is connected to an
Ethernet network.

Crystal Vision Installation
Indigo DT User Manual R1.4 16 06/07/2009
Lower/Upper slot range
This switch is used when configuring a frame pair where the two frames must have their
individual slot addresses. The position of the two-position slide switch labelled
Lower/Upper on the top edge of the front panel PCB must be placed in the lower position
for one frame and in the upper position for the other. Which frame of a pair selected to be
upper and lower is not important.
Refer to the address range table in the section entitled 'Selecting different modules' in
chapter two for the module addresses assigned when frames are operated as a pair.
The two frames should be connected so that control can pass from one frame to the other
using an RS422 serial link.
Default IP address
Switch four 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.
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
if DHCP is available. A frame serial number may also be entered.

Note: It is possible to verify that the correct frame is being viewed by first recording the Hex
switch setting (second line in status list), this is the setting of the frame address switch.
Rotate this switch to something other than the number displayed. Refreshing the browser
will then reflect this change so verifying that the correct frame is being communicated
with.

Crystal Vision Installation
Indigo DT User Manual R1.4 18 06/07/2009
To reset the IP address, select the ‘network’ link from the status page. A new page will
open, allowing entry of the required IP address and Netmask. Enter the new IP address
and Netmask information and click the ‘Change’ button. Should the frame be connected
to a DHCP running network and a fixed IP address is not required, leave all the
information blank and tick the DHCP box before selecting ‘Change’.
Network Window
Once ‘Change’ has been selected, a confirmation screen will replace the Network screen.
As instructed, lever four must be returned to the up position and the front panel power
cycled. This can be achieved by either briefly interrupting the power to the frame or, if
this is not convenient, removing the ribbon-cable connection to the front panel. Care must
be taken not to bend any pins in the cable connect as attempting to re-straighten any bent
pins will likely result in their fracture.
Confirmation Window
Should an incorrect IP address be added an error dialogue box will be displayed
indicating the likely cause of the error condition.

Crystal Vision Installation
Indigo DT User Manual R1.4 19 06/07/2009
Adding a frame serial number
The facility is given to add a serial number to each frame to aid identification, or for
auditing purposes. The frame will have had a serial number entered during manufacture;
presently this is the front panel serial number. This serial number can be freely
overwritten with any series of numbers within the specified range.
The electronic serial number consists of three groups of numbers. These groups must only
contain digits with no gaps and must fall into the range of 0-127.
An example would be 0 0 0 or 127 127 127.
From the Status window select Serial. The following box will open.
Serial number entry box
Once the desired serial number has been entered, press the ‘Store’ button to save it to
memory. Should the chosen serial number contain an error or be out of range, an error
dialogue box will be displayed.
