Sriram,
It looks as though the diagram you have is correct. I should
warn you that I have a sonar board in which the cable was put
on backward by Polaroid manufacturing.
There is a manual that you should have for the ranging unit.
In the manual (pg 5) there are details on the pinout of J1.
Anyhow, pin 1 of J1 is marked with a 1 on the top of the ranging
unit by its J1 position. The ribbon cable is staggered in the
manner previously mentioned.
Below is a list of the pins you should concern yourself with...
PIN Function
---- ----------
1 GND
4 INIT
7 ECHO
8 BINH
9 +V
sonar --> HB
7 ==||====
|| to position 7
9 ==||==== of sensor array
1 ==||====
330
4 ---\/\/\---> pin 1 of motor socket (must remove motor drvr chip)
8 -----------> pin 9 of motor socket
WARNING: if you don't have the manual, it clearly states that the unit
should not be pulsed with no transducer present. Damage to the ranging
unit may occur.
I hope this helps. PLease let me know if you have any other questions
or if haven't been clear on anything.
