hello friend,
I have a problem regarding communication cards.
A Ethernet (DOMS) communication connected with a Petrol pump dipenser CPU through communication port through RS 232 cable and cable is grounded at DOMS ground. and DOMS is grounded through general Electrical ground.
Intiailly the dipenser is communicated with the DOMS, but after 2-3 days both the communication port of DOMS and dispenser CPU are burnt out. At some places, CPU also burn out.
Can anybody help me out from this problem.
