Crystal Vision Introduction
Indigo DT User Manual R1.4 3 06/07/2009
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.

2.2 Rack mounting and ventilation
The Indigo series of desk top boxes are designed for tabletop use, however they must
have adequate ventilation. On no account should the side ventilation grilles be blocked.
If the optional rack ears are fitted, and the unit is installed in a standard 19" rack, cool air
circulation should be available and both side ventilation grilles should be unobstructed.
Indigo DT air-flow
Install the Indigo DT in a standard 19" rack as follows:
•Fit the optional rack ears
•Mount in the rack and secure via the rack ears
•Allow adequate space for the fan intake at the right hand side and the exhaust
through the left hand side (viewed from front)
Note: It is possible to operate the frame with the front panel open, however the frame may not
meet electromagnetic compatibility (EMC) requirements in this condition.
2.3 Frame connectors
The following connectors are available at the rear of the frame:

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.

7 RX+ RS422 – Link bus i/p
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).
