1 Introduction
1.1 Overview
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. CAN-2088D is a DeviceNet
slave module and it has 8 PWM output channels and 8 digital inputs. It can be
used to develop powerful and cost effective analog control system.

2.2 The Node ID & Baud rate Rotary Switch
The rotary switches for node ID configure the node ID of CAN-2088D
module. These two switches are for the tens digit and the units digit of node ID.
The node ID value of this demo picture is 32.
Node ID rotary switch
The rotary switch for baud rate handles the CAN baud rate of CAN-2088D
module. The relationship between the rotary switch value and the practical
baud rate is presented in the following table.

2.3 LED Description
PWR LED
The CAN-2088D needs the power of 10 ~ 30 VDC. Under a
normal connection, a good power supply and a correct voltage
selection, as the unit is turned on, the LED will light up in red.
NET LED
The NET LED indicates the current status of the DeviceNet
communication link.
