3Z4L Laser Micrometer Protocol Appendix N
The value -0.12345 is stored as follows:
Area of decimal portion: 2345; Area of integer portion: 0001; Sign area: F000
Memory Switch Set 1 (3000-series, High-speed Type)
(Sequence No. 421 (Hex 01A5))
This sequence sets memory switches.
Send Data Word Allocation (3rd Operand of PMCR(260))
Receive Data Word Allocation (4th Operand of PMCR(260))
None.
Note 1. Memory switches cannot be set when DIP switch SW3, pin 5 of the Laser Micrometer is not turned
ON.
2. The setting (y, z) of RS-232C takes effect when the power supply is turned back on.
