16. DATA OUTPUT TO EXTERNAL EQUIPMENT
The measured data can be exported to a remote computer
through the connector X2.
To export the output data, you must to apply the voltage of 3 to 8
V from the connected computer to the pin 9 of the connector X2.
The amplitude of the output signals will depend on the value of
the supplied voltage.
The measured range information is exported in cycles by a
binary decimal code through four data and three address buses
according to Table 16.1.
The strobe starting the data export appears on pin 8 of the
connector X2 in form of a positive pulse edge.

ones of meters (0000 or 0101)
tens of meters (from 0000 to 0101)
hundreds of meters (from 0000 to 0101)
thousands of meters (from 0000 to 0101)
tens of thousands of meters (from 0000 to
0011)
In each cycle, the digits of the binary decimal data code are
delivered to the pins of connector X2 in accordance with the
schematic circuit diagram of the range finder given in Fig.3.
The rangefinder is operable in the temperature range between –
40 and +50 °C, relative air humidity of up to 98% (as taken at
35 °C), air pressure of 61 kPa (460 mm Hg) minimum, and in the
sea mist conditions. It is powered with a rechargeable battery 10
D-0b55С-1. It can be powered with a vehicle electrical system
providing (27±2.7) V, or non- rechargeable battery producing
from 12V to 14.5V or from 22V to 29 V.
Upon receipt of the rangefinder and prior to operation the
user should proceed as follows:
- check to see that the seals on the wooden and metallic
packaged are intact;
- check completeness of the range finder against Section 5 of
this manual;
- check to see that the serial number of the rangefinder is the
same as indicated in Sections 17-19;
- make sure that the optical surfaces are free from grease
stains, dirt, cracks and condensed moisture. Remove dirt and
grease as directed in item 1 of table 11.1;
- inspect the range finder exterior for physical damage (no
cracks, dents, deep rust are admitted);
- check the dehydrator for working condition. If the silica gel
is pink in color, replace it with the new one taken from
individual SPTA set (item 11.6.3);
- place the battery in operation as directed in Section 16 of this
manual (the rechargeable battery is supplied uncharged).
