Meaning of the characters in the table:

0 = a 0 (zero) must be in this position

– = the characters in this position are immaterial

X = represents a digital value

E = single digit (least significant value)

Z = Number and Ten´s position of a number (e.g. ZZ )

H = Hundred´s position of a number

Q = Cross sum

• = Decimal point

The program interrogates only those bytes which are relevant for the function under consideration.

Example:

Byte 10 and 11 (dimension) have no meaning for the function select "Program n umber". The

program therefore ignores these bytes. The digits in Byte 11 and 12 have only a meaning for the

cross sum.

The following order of entries is mandantory when entering a parameter-program via the serial

interface:

1. Select program number

2. Sensor number / sequence

3. Communicate nominal thickness

4. Communicate limit threshold

Every command issued to the R1000 is acknowledged with a error status message. Exceptions are

requests for measurement values, down load and programs.

If the error status message contains an error code in Byte 8/9 which is different from zero, then it is

necessary to eliminate the cause of the fault.

In order to procede working with the unit it is necessary to acknowledge the error with the

command ”Request error message/delete“.

The fault cannot be acknowledged or deleted if the cause is not eliminated.

Commands issued from the R1000 (Version C only)

The R1000 responds to a request for measurement value or error code as follows:

Byte

Measurement value STX - M + X • X X X X Dimension QH QZ QE ETX

Error status STX - F + 0 0 0 0 ZZ ZE - - QH QZ QE ETX

If no measured value is present, then it supplies:

at mm: STX,0,M,+,-,-,.,-,-,-,-,M,M,QH,QZ,QE,ETX

at inch: STX,0,M,+,-,.,-,-,-,-,-,I,N,QH,QZ,QE,ETX
