RS Link* function
It is possible to connect a maximum of 10 counter units together to carry a
maximum of 60 channels of multi-point measurement at a time.
For this connection use the dedicated RS link cable; 02ADD950 (0.5m),
936937 (1m) or 965014 (2m) (The maximum total length of RS link cables
permitted for the entire system is 10m.)
RS-232C Communication Functions
Makes it possible not only to log measured values but also make various
remote settings including the zero-setting of a counter, etc.

Command format Corresponding output Function
GA**CRLF G#**, +01234.567CRLF
Outputs the [Displayed value] through
RS-232C.
CN**CRLF CH**CRLF
Switches the display to the [Current
value].
CX**CRLF CH**CRLF
Switches the display to the [Maximum
value].
CM**CRLF CH**CRLF
Switches the display to the [Minimum
value].
CW**CRLF CH**CRLF
Switches the display to the [TIR
(runout)].
CR**CRLF CH**CRLF Zeroset
CL**CRLF CH**CRLF Clears the peak value.
CP**, +01234567CRLF CH**CRLF
Inputs the preset value and performs
presetting.
CD**, +01234567CRLF CH**CRLF Inputs tolerance value.
CG**, +01234567CRLF CH**CRLF Inputs tolerance value.
CS**CRLF CH**CRLF Cancels the error.
CK**CRLF CH**, $CRLF ($=0 or 1) Confirms the HOLD state.
CT**CRLF CH**,+01234.567CRLF
Outputs the [Displayed value] through
RS-232C.
**: denotes a gage channel number between 01 and 99 (“00” means all channels).
#: denotes the type of data [N: Current value, X: Maximum value, M: Minimum value, W: TIR (runout).
CRLF: CR (carriage return), LF (line feed).
Note 1:
For presetting and tolerance limit setting, enter each value consisting of a sign and 8 digits of numeric
value without a decimal point.
Note 2:
Perform the tolerance limit setting in the order of CD and CG for the case of 3-step tolerance judgment,
and in the order of CD, CE, CF, and CG for the case of 5-step tolerance judgment.
Note 3:
The RS communication function will be suspended during key operation (e.g. setting parameters, preset
values, or tolerance limits). It automatically resumes the command and data output operation when the
gage is recovered to such a condition that the counting is possible.
Note 4:
For canceling the counting-standby state, use CS00CRLF (specification of all channels).
