1. Introduction
M-7088 has 8 PWM output channels and 8 counter inputs. It can be used to develop
powerful and cost effective analog control system. PWM (Pulse width modulation) is a
powerful technique for controlling analog circuits. It uses digital outputs to generate a
waveform with variant duty cycle and frequency to control analog circuits. It can be used
to Controlling the position/speed of motors, Dimming the brightness of lamps,
Controlling the speed of fans… etc.

PWM Duty Cycle = 50%
PWM Steps = 1 (Continuous Type)
5. Configuration
To install the module, follow the steps below:
1. Connect the thermistor analog input.
2. Connect the module to the RS-485 network using the DATA+ and DATA- terminals. If
the host is only equipped with an RS-232 interface, then an RS-232 to RS-485
converter will be required.
3. Connect the module to the power supply using the +Vs and GND terminals. Note that
the voltage supplied should be in the range of +10 to +30V DC.
4. Open DCON utility pro
click on COM port(first icon).
It can select multi-options such as Baud Rate, Protocol, Checksum, and Format to
search module. The default settings for the module can be found in Section 3. Click OK
after selecting the COM port setting.

5. DCON utility pro will search for the selected COM port according the setting
previously set. DCON Utility Pro supports DCON and Modbus protocol for all ICPDAS
and the others modules.

7. For M-7000 modules using the Modbus RTU protocol, configure the module using the
following functions.
Sub-function 04h of Function 46h, see user manual Section 3.3.2
Sub-function 06h of Function 46h, see user manual Section 3.3.4
Sub-function 08h of Function 46h, see user manual Section 3.3.6
For M-7000 modules using the Modbus RTU protocol, use Function 04h to read the
data from the input channels. See user manual Section 3.2 for details.
