1. General
Thank You for purchasing our ADPC-101 navigation device. Design and production of
this device are developed in compliance with applicable industrial standards for marine use.
This device is mounted on ships with gyrocompasses and logs not capable to generate
current values in NMEA format for navigation equipment needing course and speed data in
digital form.
Device executes the following functions:
Reception of current course value from gyrocompasses with synchro or stepper
interface;
Reception of current speed value from logs with stepper interface or interface on
“closing” contact;
Indication of current speed and course values in built-in display;
Conversion of received data into NMEA-0183 format;
Transmission of converted course and speed data via standard interface (RS-232 and
RS-422/485 ports) to external devices in NMEA-0183 format.
Operating modes of this device are easily tuned by user-friendly menu options and
widely used symbols on keyboard pads.

5. Unit operation
Caution
Before device commissioning, at first complete installation procedure (see para. 4
“Device installation”) and connections (see p.4 “Device Installation”).
5.1 Device switch on procedure
When power is applied, device transfers to review mode of course and speed values;
besides, readings of compass or log values are indicated as zeroes and the signal at converter
output will be disabled. The unit is in standby mode for input of initial course value and
instructions for applicable types of gyrocompass and log. Before input of an initial course value
the alarm system will work.
To achieve correct device operation, select type of compass and log in menu settings
(see p.6 “Menu functions and changing of settings”) and manually enter the current course value
for gyrocompass in use.
Should received values of compass and log are not trustworthy, display with show the
sign ‘?’ (question) at the beginning of relevant line.
- indicator readings during device power ON (mode of
review for current course and speed values).
Note
When the type of compass, namely stepper/synchro is switched over, again enter the
current gyrocompass value.
5.2 Input of initial course value
look at and remember course readings on gyrocompass, which is connected to the
unit;
press on the key [1] on converter keyboard;
there will be a prompt to enter course value:
enter course value by using keys with applied digits and decimal point [.];
Press [ENTER].
The screen returns to a mode for review of current compass course and log speed,
delivery of a sound signal stops .
When it is necessary to edit or delete the last character of entered value one may use the
key [CLEAR].
Keys [.] and [CLEAR] are entered in the upper case and after depression [.] the case
automatically shifts to the lower case and remains in the upper case when [CLEAR] is
depressed.

Unicont SPb Ltd Technical Documentation ADPC-101
Page 12
Use key [SHIFT] key to change cases.
The status of case can be visually defined by cursor status:
blinking cursor with illumination of font recticle –lower case;
no blinking (underlining) –upper case.
Caution
All tuned options are stored in ROM memory and remain unchanged after power
ON/OFF. If gyrocompass course readings were changed during converter power OFF period,
enter a new current course value to ensure correct operation of device.
Note
In this mode of tuning one may enter a number with floating point and one decimal
point of decimal fractions. If incorrect value is entered (over 359.9) the number will be ignored.
In case of operator idling and selected option unuse timeout (in position 5s, 10s, 15s,
20s, 25s except for OFF) there will be an automatic exit from input mode to review mode of
course and speed values without changing of any option.
Selected options are preserved only after depression on [ENTER].
After selection of gyrocompass and log types and input of initial course value and
reception of trustworthy data, device starts to transmit NMEA signal to both outputs RS-232 and
RS-422/485 in parallel, once per second.
Example.
For input value “320.3” should press: [1] [3] [2] [0] [SHIFT] [.] [3] [ENTER]
6. Auxiliary mode for display of signal status at input
terminals.
In this mode display shows logical status of signals at device inputs which may be used
during device deployment.
To go into this mode press on [9] key.
logic ‘0’ denotes that a signal level at relevant optically isolated input is below
switching threshold.
logic ‘1’ denotes that a signal level at relevant optically isolated input has exceeded
switching threshold.
123 1st, 2nd, 3rd gyrocompass’s windings
For input of “closing contact” type log

Unicont SPb Ltd Technical Documentation ADPC-101
Page 13
logic ‘0’ denotes that the contact is opened
logic ‘1’ denotes that the contact is closed.
The unit will be in this mode until operator initiates exit by pressing on any key.
7. Additional displaying modes
7.1 Total trip displaying
In this mode display shows total trip of a ship after last nulling of total trip counter.
Nulling except after shutdown of converter or with pressing [7] key by operator. After activating
this mode upper string of display with log information changed to string with information about
haul.
To go into this mode press on [F2] key. To go out from this mode press on [F2] key
again.
NMEA data output in this mode does not stop or change.
7.2 Displaying of ROT (rate of turn)
In this mode display shows current rate of turn of a ship. After activating this mode
lower string of display with current heading information changed to string with information
about ROT.
To go into this mode press on [3] key. To go out from this mode press on [3] key again.
8. Menu functions and changing of settings
Press on [F3] key and enter menu of settings. Use [3], [0] keys (up and down) for
scrolling between options.
Use [6], [8] keys (left, right) to select probable option values.
Again press on [F3] key for exit from selected mode. Selected options are stored only
after pressing on [ENTER].
When operator is idling and unuse timeout option is selected (in positions 5s, 10s, 15s,
20s, 25s except for OFF) an automatic exit from the menu is initiated without changes of any
option.
