I have captured this string from the comomunication:

0123001E053A00041234567800010A0011010000000000000000474747474747474732F5

0125001E053A00041234567800010A00110100000000000000004747474747474747339D

0127001E053A00041234567800010A00110100000000000000004747474747474747B346

0129001E053A00041234567800010A00110100000000000000004747474747474747314D

I think that the last four digit are the cheksum, but could not get the algoritm to calculate it.

I'll be so happy if some one help with it.

Thanks.
