Page 3: Features
Introduction Welcome to the SuperLogics ADC-1R2 Series of I/O modules. These modules using RS-232 communications are available in different configurations dependent on your needs and applications. In addition they are offered in an enclosure, or open allowing you the end user complete flexibility when determining the parameters for your project. -
Page 4: Quick Start
Quick Start Instructions You need the following: • EZTerminal program available free on our website http://www.SuperLogics.com • An open COMPORT on your PC • Power supply PS9J (9VDC 400 ma unregulated) • A cable to connect your PC (C9F9M-6 6 foot serial cable) - Page 5 Step 4 Your First Command Now that you have a EZTerminal session running, your ready to power up the ADC-1R2 Series I/O Module. After powering up your ADC-1R2 Series Module, EZTerminal will receive a welcome message from the unit indicating you are ready to provide your first command.

Page 6: Communications
Communications The SuperLogics ADC-1R2 Series I/O Modules support RS-232 communications interface using simple ASCII commands. A carriage return (decimal code 13 or Hex code 0x0D) marks the end of each command. Line feeds (decimal code 10 or Hex code 0x0A) are ignored. -

Page 9: Analog Control Nibble
Technologies LTC1296 analog to digital conversion chip. In the process of performing a data sample, the user sends a control nibble to the ADC-1R2 Series module. The ADC-1R2 Series module in turn performs a data conversion using the control nibble and transmitts a response data sample back. -

Page 12: Sampling Rates
These modes of operation can be used singularly or together in combination. #1) Polled Mode By far, the Polled Mode is the most common usage of the ADC-1R2 Series I/O modules. In this mode the Host computer sends a command to the I/O Modules which in turn sends an associated response back to the Host computer. -
Page 13: Continuous Stream Mode
Range = .002 second - 65.5 seconds #2a) Asynchronous Update Mode — State Change Update When EEPROM locations 0x04/0x05 = 0x01, the ADC-1R2 Series I/O module enters an asynchronous update mode whereby any detected change on the Digital Input port or the Counter Capture port causes the I/O module to transmit data to the host. -

Page 17: Pwm Characteristics
Pulse Width Modulation (PWM) Characteristics The ADC-1R2 Series modules have a configurable PWM output. There are two settings to configure for proper PWM operation: PWM frequency and PWM duty cycle. PWM — Command Pxxyyy xx = Pwm_Divisor yyy = Pwm_Duty (10 bits max.) Pwm_Divisor = 0x00 ... -
Page 18: Analog I/O Characteristics
CLK frequency. Sampling Analog Voltage Inputs By far the most common configuration of the ADC-1R2 Series I/O modules is to sample voltage values. Analog voltage levels are converted to integer digital values using the Linear Technologies LTC1296 A/D (Analog/Digital) chip. -
Page 19: Analog Conversion
1 LSB bipolar = 0.0024414 volt Voltage Conversion The Analog conversion value obtained from the ADC-1R2 Series module is represented as an integer value (either signed for Bipolar samples or unsigned for Unipolar sample) and is normally converted to a Real or Floating Point number for ultimate usage. -
Page 20: Analog Current Sampling
Watch out for UPS systems! They create loads of EMI/EMF noise. • Keep the analog signal source as close to the ADC-x module as possible. • Keep transformers far away from the ADC-1R2 Series module. • Use good wiring practices, especially in regards to ground connections. •... -
