INTRODUCTION
This operating manual (hereinafter referred to as OM) is intended to describe
structure, operating principles, technical service and usage of Analog-to-digital convert-
er ADPC-101 (hereinafter referred to as the Product, ADPC-101).
In addition to the instructions given in this document, the safety regulations and
rules applicable in the field shall be observed.
Only those who have read and understood this document and those who have
had special training shall be permitted to operate with the PSU according to the applica-
ble regulations.
Terms and abbreviations:
OM –operating manual;
S –software;
SC –short circuit;
ТS –technical service;
CL –check list;
LCD –liquid-crystal display;
ADPC-101 –analog-to-digital converter ADPC-101;
LFSG –large fine-pored silica gel granular.
NMEA (National Marine Electronics Association) –text communication pro-
tocol for interconnection of marine (normally navigational) equipment.
Synchro (Selsyn) –electrical AC self-synchronizing micromachines (for
smooth transmission of shaft degree).

1DESCRIPTION AND OPERATION OF THE PRODUCT
1.1 DESCRIPTION
The Product ensures Analog-to-digital conversion of obsolete signals from gy-
rocompasses and logs in NMEA 0183 sentences and transmission of these data to the
corresponding navigational equipment.
The Product is used on the ships equipped with gyrocompasses and logs. They
do not output current data in NMEA 0183 sentences (IEC 61162) to navigational
equipment, which requires course and speed data in digital format. The Product may be
installed on communication ships due to their re-equipping with automatic identification
system and act as a connecting device converting data from obsolete compasses and
logs.
1.2 TECHNICAL SPECIFICATIONS
1.2.1 The Product performs the following functions:
a) Reception of current course data from gyrocompass with synchro or stepper
interface;
b)Reception of current speed data from logs with stepper interface or closing
contact interface;
c) Display of current speed and course data on the integrated LCD;
d)Conversion of received data into NMEA 0183 format (IEC 61162);
e) Transmission of the converted speed and course data as well as ship rate turn
via standard interface RS-232 and RS-422/485 to external equipment in NMEA 0183
format (IEC 61162).
Intuitive menu options and convenient keyboard enable user-friendly settings of
the operation modes.
The Product is manufactured in robust moisture-proof metal casing, which may
be mounted on bulkheads inside premises.
1.2.2 Types of connected equipment:
a) gyrocompasses:
SYNCHRO type gyrocompass;
STEPPER type gyrocompass;
b)logs:
stepper type log (pulse);

1.3.2 Connection diagrams of the Product are represented in Figures 2–4; for
the layout and assignment of printed circuit board terminal connectors, see Figures 5
and Table 3.
To change switching threshold of log and gyrocompass optoisolated inputs, use
DIP-switches «J4», «J5», «J6», «J7», «J8», and jumpers (see Figure 5). If contacts are
closed, threshold input voltage is 6 V, if opened - 3 V.
Threshold voltage, if DIP-switches «J4», «J5», «J6», «J7», «J8» are opened and
closed, are represented below:
а) or –threshold voltage approx. 3 V;

b) –threshold voltage approx. 6 V.
DIP-switch «J10» status:
а) –ADPC-101 is an end device on
RS-422/485 channel;
b) –ADPC-101 is a middle device on
RS-422/485 channel.
Connectors «J9», «J1» (see Figure 5) are used for device configuration at manu-
facturing stage and not used during operation.
