CB-7013, CB-7033 User’s Manual31. Introduction
CB-7000 is a family of network data acquisition and control
modules. They provide analog-to-digital, digital-to-analog, digital
input/output, timer/counter and other functions. These modules canbe remote-controlled by a set of commands. Common features of
the CB-7013/13D and CB7033/33D are as follows:l24-bits sigma-delta ADC for excellent accuracy.

Calibration Sequence:
1. Connect calibration resistor to module by 4-wire R TD
connection. For CB-7033/33D, connect to channel 0.
2. Warm-Up for 30 minutes.
3. Set Type to 20- Ref. Sec .2.1.
4. Enable Calibration - Ref. Sec. 2.15.
5. Install Zero Calibration Resistor.
6. Preform Zero Calibration Command - Ref. Sec. 2.6.
7. Install Span Calibration Resistor.
8. Perform Span Calibration Command - Ref. Sec. 2.5.
9. Repeat step 4 to step 8 three times.
Note:
1. Step 4 is not needed for CB-7013/13D, version A1.x or A2.x.
2. Same for type 2A only different for set different type (step 3),
and install different Zero/Span Calibration Resistor (step 5, 7).

Calculate Checksum:
1. Calculate ASCII sum of all characters of command (orresponse) string except the character return (cr).
2. Mask the sum of string with 0ffh.
Example:Command string: $012(cr)Sum of string = ‘$’+‘0’+‘1’+‘2’ = 24h+30h+31h+32h = B7h.
The checksum is B7h, and [CHK] = “B7”.
Command string with checksum: $012B7(cr).
Response string: !01200600(cr).
Sum of string: ‘!’+‘0’+‘1’+‘2’+‘0’+‘0’+‘6’+‘0’+‘0’= 21h+30h+31h+32h+30h+30h+36h+30h+30h = 1AAh
The checksum is AAh, and [CHK] = “AA”.

3. Application Note
3.1 INIT* pin Operation
Each CB-7000 module has a build-in EEPROM to store
configuration information such as address, type, baud rate, and otherinformation. Sometimes, a user may forget the configuration of themodule. Therefore, the CB-7000 modules have a special mode
named “INIT mode”, to help user to resolve the problem. The“INIT mode” is setting as Address=00, baud rate=9600 bps, nochecksum
To enable INIT mode, do the following steps:
Step 1. Power-off the module.
Step 2. Connect the INIT* pin to the GND pin.
Step 3. Turn power on.
Step 4. Send command $002(cr) at 9600 bps to read theconfiguration stored in the module’s EEPROM.
Refer to “7000 Bus Converter User Manual” Sec. 5.1
and “Getting Started” for more information.

3.2 Module Status
Power-On Reset or Module Watchdog Reset will put all
outputs to Power-On Value. And the module may accept the host’scommand to change the output value.
Host Watchdog Time-out will cause all digital outputs to
go to their Safe Value. The module’s status (read by command~AA0) will be 04, and the output command will be ignored.

3.3 Dual Watchdog Operation
Dual Watchdog = Module Watchdog + Host Watchdog
The Module Watchdog is a hardware reset circuit tomonitor the module’s operating status. While working in harsh or
noisy environment, the module may go down by the external noise
signal. The circuit may let the module to work continues and neverhalt.
The Host Watchdog is a software function to monitor the
host’s operating status. Its purpose is to detect a network/communication problem or host halt. When a time-out occurs, themodule changes all outputs to the safe state to prevent
possible dangerous problems of a controlled unit/process.
The CB-7000 module with Dual W atchdog makes thecontrol system more reliable and stable.
