Precautions for startup
y
Either turn on the power switch of all Counters simultaneously or turn on the
power switch of each Counter sequentially, beginning with the rst Counter.
y
After startup, [- - - - -] will blink, and then, after the initial settings have
completed, the Counter enters the stand-by state, where [- - - - -] is displayed.
This state can be canceled using [SEL]/[CE], an external HOLD signal, or an
RS command.
Tips
For details, see "6.2.1 List of Error Codes" (page 50).
y
Parameters relating to RS-232C (No. 25 to 28) can be modied only on
the rst Counter. If you modify a parameter, reset the power switch of all
connected Counters.
5.4.2 RS-232C Data Output Duration
The maximum output duration of the command to output all data (GA00CRLF)
can be calculated with the following formula:
Maximum output duration [ms] = Number of connected Counters × 5 + Number
of connection channels × 17 (8.5) + 6 (3)
Tips
Transmission rate is 9600bps. The values enclosed in ( ) show the case of 19200 bps.
Calculation example:
1 EH-102 + 1 Linear Gage channel = Max. 28 (16.5) ms
10 EH-102 + 20 Linear Gage channels = Max. 396 (223) ms
Tips
Processing time of the PC is not included.
