10. COMMUNICATION FUNCTION
10 - 33
(b) Rising latch data or falling latch data (data part + additional information)
Reads MSD (Mark detection) rising latch data or MSD (Mark detection) falling latch data.
1) Transmission
Transmits the command [1] [0] + the data No. [0] [2], [0] [3] corresponding to the point tables to
read. Refer to section 10.1.1.
2) Return
The slave station returns the speed data of point table requested.
Data will be received in hexadecimal per set command.
Hexadecimal should be changed to decimal.
Example
Data "0040000186A0" will be 100.000 mm in the command-side unit.
Decide the decimal point position with [Pr. PT01] and [Pr. PT03].
Display type
0: Data must be converted into decimal.
1: Data is used unchanged in hexadecimal.
Decimal point position
0: No decimal point
1: First least significant digit (not used normally)
2: Second least significant digit
3: Third least significant digit
4: Forth least significant digit
5: Fifth least significant digit

Note. When you assign MSD (Mark detection) to the CN1-10 pin with [Pr. PD44], this can be accepted faster (within 0.4 ms). When
assigning MSD (Mark detection) to the CN1-10 pin, set "Mark detection fast input signal filter selection" in [Pr. PD31].
10.3 Settings equivalent to previous models
You can change the status monitor display and DIO function map to communication commands of MR-J3-T
or MR-J2S-CP with "RS-422 communication - Previous model equivalent selection" in [Pr. PT01].
