The 4 Digit Subsea Display (not dual), may also be mounted within a Remote Actuator
Assembly, that provides a facility for switching the zero display, scaling and units functions.

RS232 Serial Interface / Command Console Interface
The Subsea Display has an RS232 serial interface to allow configuration of various aspects of
the system functionality using the “Command Console Interface”. The system options
defined elsewhere within the system manual may be configured as required via the
Command Console Interface using a PC with an RS232 port and a communications program
such as “Windows Hyper Terminal”.
Normally the Jupiter Subsea Display system outputs the display reading over the RS232
serial interface whilst it is active.
The operational mode must be set for the system application, – see “System Modes”.
The system scale factors must be set to give the correct display for a given input, – see
“Calibration”.
Note: A Serial Interface Cable to connect to a standard PC 9 pin RS232 connector is supplied
with the Subsea Display System (Part No. 023-14-11-020). Connection to a USB port is
possible via a suitable USB to RS232 convertor. Contact Zetechtics, for further information.

INTRODUCTION
BRIEF DESCRIPTION
All Jupiter Subsea Display Systems are rated to 3,000m depth in sea water, and can be
interfaced to a Jupiter Subsea Control System or data-link. They are stand-alone, battery
powered, ultra low power consumption with selectable dormant state. Designed for Strain
Gauge input and/or Digital Sensor input and display either individually or simultaneously.
The Jupiter Strain Gauge Subsea Display System is a simple means of measuring a strain
based variable (such as pressure, torque, etc.) when an electronic control system is not fitted.
The Subsea Strain Gauge Display System can be calibrated to display any variable with a
scale and offset applied to ensure that the user sees a real world value directly related to the
measurement in question.
The Jupiter Subsea Quadrature Counter System is a means of monitoring how a
Quadrature Sensor, changes state, when an electronic control system is not fitted. Sensor
types, including contact closure such as a Reed Switch and Inductive Proximity (including
NAMUR) types are supported.
For example if a rotating tool, is fitted with a Quadrature Sensor, which has a known number
of changes of state per revolution, then the 2 or 4 digit display will show the number of full
revolutions, together with an indication of whether a partial revolution has occurred.
2 Digit Display:Can be used as a 2 digit counter only.
4 Digit Display: Can be used as either a 4 digit counter display or a 4 digit strain gauge
input display. An externally applied magnet can quickly and easily zero the display as well as
changing the unit between scaled and un-scaled modes or units, ie. Nm / lb.ft.
Dual 4 Digit Display:Can display count and strain gauge input simultaneously. An
externally applied magnet can quickly and easily zero the display as well as changing the unit
between scaled and un-scaled modes or units, ie. Nm/lb.ft.
Both 2 and 4 Digit Counters have a user set 5V or 10V power supply provided for the input
sensor(s).
All Jupiter Subsea Display Systems have a visible low battery indication and power saving
options, which can user configured.

MOUNTING THE SYSTEM
The system should be attached to a secure and stable structure so that there is good visibility
of the output display. The means of mounting will be dependent on the specific application,
however using a worm drive hose clip (such as a Jubilee® clip) to secure the cylindrical body of
the system to channel section proves an effective method.
The 4 Digit Subsea Display (not dual) may also be mounted within a Remote Actuator
Assembly, Part No: 023-14-16-002, that provides a facility for switching the zero display,
scaling and units functions. If this is the case the system will be mounted directly to the
Remote Actuator as detailed in the General Assembly Drawing, Doc. No: 023-14-16-001, which
in turn should be mounted using the 2 off mounting holes on the front flange. The position and
size of these mounting holes are detailed in the General Assembly Drawing. Consideration
should be made to the mounting position to allow the actuator levers to be operated.
If a Remote Actuator Assembly is required for a Dual 4 Digit Subsea Display, then please
contact Zetechtics.
Note: Adapter holes are provided on the Remote Actuator to allow for mounting of adapter
levers (not supplied by Zetechtics).
If the front glass of the 2 digit display is scratched or otherwise damaged, the Unit should be
returned to Zetechtics for replacement/pressure testing.
