Mitutoyo ID-H0530 - Output data format (DATA1); Timing chart

No. 99MAH016B
4-2
IMPORTANT
 Since the power voltage differs between the ID-H and external device sides, absolutely
use an open-collector output circuit or open-drain output circuit on the external device
side. Do not use a CMOS output circuit.
 Pin 8 is a terminal dedicated to the RS-232 communication. It is not possible to
transmit from the external device or transmit to it.
4.1.3 Output data format (DATA1)
NOTE
• Up to 6 digits of numeric values can be outputted as the SPC (Digimatic) output. If the 7
digits of numeric value such as “123.4565mm” is outputted, for example, the
instrument output the SPC data as “23.4565mm”.
4.1.4 Timing chart
IMPORTANT
• If the output request (REQ) signal is received during the spindle displacement or if
the inverter receives output request (REQ) signals repeatedly at short intervals, the
instrument may not output data.
NOTE
• Retain the REQ signal at Low level until the CK signal is outputted. Also, return the
REQ signal to High level before the last CK signal (at the 52nd bit) is outputted.
