Posted 12 Jun 2017 Decrease the number of outputs you read, or do you really have over 100 outputs ? Try with the first 16 ones and see how it goes. Else, see if you can read them as a register (Y0-Y7 + Y10-Y17) using function code 0x04 and address 0xA7A8. Do keep in mind that the address asked for might be offset by 1.

Posted 20 Jun 2017 In Modscan32 you need to use the address 14193, because Modscan 32 address is decimal, not hexadecimal 0x3770 = 14192 decimal Since hexadecimal addressing is usually zero based, and decimal addressing is usually one based, the 3770 (hex) register is probably at 14192 +1 = 14193 (decimal) Note that the format for displaying values in Modscan can be changed from binary to hex to integer or floating point, but the address is always a decimal number.
