Data Formats
ASCII ASCII characters packed 2 per register in high, low order and without any termination characters. .
SINT16 / UINT16 16-bit signed / unsigned integer.
SINT32 / UINT32 32-bit signed / unsigned integer spanning 2 registers. The lower-addressed register is the high order half.
FLOAT 32-bit IEEE floating point number spanning 2 registers. The lower-addressed register is the high order half (i.e., contains the exponent).
TSTAMP 3 adjacent registers, 2 bytes each. First (lowest-addressed) register high byte is year (0-99), low byte is month (1-12). Middle register high byte is day(1-31), low byte is
hour (0-23 plus DST bit). DST (daylight saving time) bit is bit 6 (0x40). Third register high byte is minutes (0-59), low byte is seconds (0-59). For example, 9:35:07AM on
October 12, 2049 would be 0x310A, 0x0C49, 0x2307, assuming DST is in effect.
