2) Loading parameters [2-axis model]

*1 Clearing this parameter allows the unit to restore the unit conditions at shipment

*2 A type of gauge, like LGF-Z, which has the specific internal origin, will generate signals the moment when the spindle is moved and a reference point on it passes over the internal origin. Based on this mechanism the

EH-Z will restore the preset position.

*3 Usually the origin point detection is performed only when the unit power is turned on. However, the unit operation will enter the wait state for origin re-detection at the rise of the HOLD signal where the origin re-detection function has been activated by the corresponding parameter. If the HOLD signal is inputted again after the origin is re-detected, the origin re-detection function will be canceled except during cancellation of any error.

*4 An ABS-type gauge continuously memorizes the origin even when the unit power is OFF. Make up this setting according to the type of gage to be used. Activate the INC mode when you want to make the displays on a gage like ID and SD and on the counter consistent.

*5 The operation is valid after the unit power is turned on.

*6 The EH-D may cause an error rarely when it is connected with a special type of gage. If this is the case, set

PNo.19 to either 1 or 2.

*7 When a 7-inch gage is connected as to read 1/10,000 (only for EH-D).

*8 In relation to output of +000000, the [ ] shows the voltage of the numerical data line and ( ) shows the voltage of the sign.

*9 The setting range may be limited depending on the setting of PNo=10. Example) If PNo.10=0, a range of 0 to

4 is permitted for PNo.12.

*10 EH-D model can not perform speed measurement. Use EH-P/Z/S.

*11 During the peak mode the preset value is established based on the peak value.

*12 Modifying the parameter will clear preset values and tolerance values having been set.

CK**CRLF CH**,%CRLF HOLD status *4

*1 [**] denotes a gage channel number between 01 and 99("00" means all channels).Channels 01 thru Channel 04 are assigned to CEL1 to CEL4, respectively.

[#] denotes the type of data［N : Current value, X : Maximum value, M : Minimum value, W : TIR］.CRLF means CR（carriage return）plus LF（line feed). Output during error will be "CH**,Error$$CRLF"（$$ is the error code. Refer to "12. Error

Displays").

*2 For presetting and tolerance limit setting, enter each value consisting of a sign and 8 digits of numeric value without a decimal point.

*3 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. When the order of tolerance limits is different from the correct order, or if the data according to the set number of steps is different from those which are actually sent out, an error will be outputted. If this is the case, redo the settings from the beginning of the CD command.

*4 A response output of CK command ("%") shows the HOLD status.

%＝0 : Normal state, 1 : HOLD status

All counters which are LINK-connected by the CK command at the time of

PNo28=1 (CH synchronization) enter the HOLD state. This HOLD state will be canceled when you attempt data read with the GA command. The CK command is valid only with CH1.

*5 If the peak mode is switched using an RS-232C command, peak values cannot be backed up in memory.

Note 1.

After you have received a response output corresponding to the previous command, send the next command. When there is no response from your command, clear the communication buffer, then

send the command again after one second or more.

Note 2.

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 3.

For canceling the counting-standby state, use

CS00CRLF(specification of all channels).

10.2 RS_LINK Function

Chain-linking more than 2 counter units as one connected to another with a single cable makes it possible to control maximum 10 counter units by the

RS-232C interface of the first counter.

1) Connection method

Connect between IN and OUT of the RS-LINK connectors as shown below :

First counter Last counter

RS-232C

RS LINK

IN OUT

RS LINK RS LINK

IN OUT IN OUT

RS LINK connection cable

Max. 10 units

MAX10m

Note 1.

Do not connect anything at the IN side of the LINK connector of the first counter and at the OUT side of the last counter.

Note 2.

Channel number of each gage will be automatically assigned to 01, 02, and 03 in this order from the first counter during the initial setting after the power is tuned on.

Note 3.

The maximum total cable length permitted for the entire system is 10m.

Note 4.

Configuring such a system that more than ten counter units are included and/or the total cable length is longer than 10m, consult Mitutoyo.

2) RS_LINK connection cable

Refer to the appropriate paragraph in "17. Optional Accessories".

3) Precautions for start-up

- Power ON : Either turn on the power of all counter units simultaneously or turn on the power of each counter unit sequentially beginning with the first one.

- Initial setting : After power on, "- - - - -" will be flashing. After the initial setting is completed, the counter unit enters the counting stand-by state where "- - - - -" is displayed. It is possible to cancel any error using the CLR key, external HOLD signal, or RS command (Refer to "12 Error Displays").

- RS-232C related parameters (Nos. 25 through 28) can only be modified on the first counter unit. When any parameter has been modified, reset the power of all counter units being connected.

4) RS command input and response output (Command:

PNo.28=0 or 1)

* While the response output is triggered by a HOLD signal, the RS232C command is disabled.

* In the RS-LINK connection mode, RS_EXT of the last counter unit is active.

6) RS232C data output duration

The maximum output duration with the Output_All_Data command (GA00CRLF) can be calculated from the following equation:

Maximum output duration [ms]

= Number of connected units x 5 + Number of connection channels x 17 (8.5) + 6

(3)

＊Transmission rate is 9600bps. The value enclosed in the parentheses shows the case of 19200bps. [Unit: ms]

(Calculation example)

One unit of EH-102 + 1 channel of gage = MAX 28 (16.5) ms

Ten units of EH-102 + 20 channels of gage = MAX 351 (178) ms

Note. Not including the processing time by the PC.

7) Communication test

Use Hyper Terminal (standard software supplied for Windows), etc., to send the

RS232C command from the Keyboard to the target counter and check the specified operation.

10.3 USB Communication Function

Optional accessory: PC data input SW

This is available when connecting with SENSERPAK

Saved only by the EH-D (ABS mode) and EH-Z (origin mode).

14.

Troubleshooting

When the unit operation looks odd, refer to the following examples:

● Counter value is odd (looks like not counting).

- Have you set correct parameters corresponding to the gage type?

- Isn't the Peak mode (MAX or MIN) active?

- Isn't the HOLD signal (shown by flashing of UNIT) being inputted?

- Haven't you set the function of calculation with constant?

● Impossible to perform zero-setting.

- Isn't the Peak mode active?

● Can not achieve RS232C communication.

- Is the cable connection correct?

- Is the unit in the RS232C mode (PNo.24=0)?

- What is the command or HOLD trigger (PNo.28) setting?

- Check the settings of communication conditions.
