DESIGNATION OF PINS OF RANGEFINDER EXTERNAL PLUGS

1.  The plug to connect  the  external power supply  and  the  remote trigger

button

- an external supply voltage of 12

±

2 V is applied to the pins 1,4 of the plug;

- the remote closure trigger button is connected to the pins 2,3 of the plug;

- a consumed current (average) is no more than 0.6 A.

2. The plug to output information on measured range

The information  on  measured range is  transmitted  from the  rangefinder to  the

computer by direct connection to the COM1 (3F8h) 9-pin port.

To  operate  the  computer,  it  is  necessary  connect  the  computer  with  the

rangefinder by  the  cable, to  start  the  LRF.EXE  control program  on  the  disk,

and switch on the rangefinder.

LRF.EXE  is  the  EG-LRF  rangefinder  control  program    to  provide

communication  of  the  rangefinder with  the  IBM  PC  having  the  WINDOWS

XP  operational  system.  For  normal  functioning  of  the  program  a  free  disk

space of about 700 Kbytes for the control module and a space that  is  unknown

beforehand for storage of the LRF.LOG output files are necessary.

In  the  LRF.LOG  files  the  measurement  data  of  the  whole  of  the  program

session is recorded.

See the description of operation of the LRF.EXE program in the file Help.txt.
