|Hardware Method:||Setup eC instruction tags correct checksum to end of the N02 response
message. Transmit instructions >00eC08CR. Now
any instruction can be assembled in the usual manner, but enter 00 for checksum.
The unit returns a N02 response message, plus the correct checksum.
|Wildcard:||If ?? is added to the instruction instead of a checksum, the instruction
is executed. It sends a "don't care" value for thechecksum. This method is
not recommended for programming, because it does not ensure proper communication
|Circulation Method:||Checksum can also be obtained by adding all decimal values
of ASCII characters that make up an instruction or response (exclude
> for instructions and A for responses). Repeatedly subtract 256 from
this sum until the remainder is less than 256. The checksum is 2 digit hex
equivalent of the remainder.
