1.6. Calibration
Warning: It is not recommended that calibration be
performed until the process is fully understood.
1.6.1 Analog Input
The calibration procedure is as follows:
1. Warm up the module for 30 minutes.
2. Set the type code to the type you want to calibrate.
Refer to Section 2.12 for details.
3. Enable calibration. Refer to Section 2.31 for details.
4. Apply the zero calibration voltage/current.
5. Send the “zero calibration” command. Refer to Section
2.6 for details.
6. Apply the span calibration voltage/current.
7. Send the “span calibration” command. Refer to Section
2.5 for details.
8. Repeat steps 3 to 7 three times.
Notes:
1. Connect the calibration voltage/current to channel 0.
2. When calibrating type 0D, the jumper for channel 0
should be set to the “current input” position.
3. Calibration voltages and currents are shown below.

DCON Protocol
All communication with the module consists of commands
generated by the host and responses transmitted by the
module. Each module has a unique ID number that is used
for addressing purposes and is stored in non-volatile
memory. The ID is 01 by default and can be changed by
transmitting the appropriate using a user command. All
commands to the modules contain the ID address,
meaning that only the addressed module will respond. The
only exception to this is command #** (Section 2.2) and
command ~** (Section 2.22), which is sent to all modules,
but, in these cases, the modules do not reply to the
command.

Data [CHKSUM]
CR
CHKSUM A 2-character checksum that is present
when the checksum setting is enabled. See
Sections 2.1 and 5.1 for details.
CR End of command character, carriage return
(0x0D)
M-7002 User Manual, Rev: 1.0 2012/04/11
17
Checksum Calculation:
1. Calculate the ASCII code sum of all the characters in
the command/response string, except for the carriage
return character (CR).
2. The checksum is equal to the sum masked by 0FFh.
Example:
Command string: $012(CR)
1. The sum of the string = “$”+”0”+”1”+”2” =
24h+30h+31h+32h = B7h
2. Therefore the checksum is B7h, and so
CHKSUM = “B7”
3. The command string with the checksum = $012B7(CR)
Response string: !01200600(CR)
1. The sum of the string =
“!”+”0”+”1”+”2”+”0”+”0”+”6”+”0”+”0” =
21h+30h+31h+32h+30h+30h+36h+30h+30h = 1AAh
2. Therefore the checksum is AAh, and so
CHKSUM = “AA”
3. The response string with the checksum
= !01200600AA(CR)
Note:
All characters should be in upper case.

2.1. %AANNTTCCFF
Description:
This command is used to set the configuration for a
specific module.
Syntax:
%AANNTTCCFF[CHKSUM](CR)
% Delimiter character
AA The address of the module to be configured in
hexadecimal format (00 to FF)
NN The new address of the module in hexadecimal
format (00 to FF)
TT Not used by the M-7002 and should be set to 00.
CC The new Baud Rate code, see Section 1.7 for
details. To change the Baud Rate, the module
should first be switched to INIT* mode.
FF The command used to set the data format,
checksum, and filter settings. See Section 1.7 for
details of the data format. To change the

switched to INIT* mode.
Response:
Valid Response: !AA[CHKSUM](CR)
Invalid Response: ?AA[CHKSUM](CR)
! Delimiter for a valid response
? Delimiter for an invalid response
(If the Baud Rate or checksum settings are
changed without first switching to INIT* mode,
the module will return an invalid response.)
AA The address of the responding module in
hexadecimal format (00 to FF)
