The ADC used in this interface module is a data acquisition component. It is a monolithic CMOS device with an 8-bit analog to digital converter with 8 channels multiplexer and microprocessor compatible control logic. The 8-bit A/D converter uses successive approximation as the conversion technique. The converter features a high impedance chopper stabilized comparator, a 256R voltage divider with analog switch tree and a successive approximation register. The 8 channels multiplexer can directly access any one of 8-single ended analog signals, and provides the logic for additional channel expansion. Signal conditioning of any analog input signal is eased by direct access to the multiplexer output, and to the input of 8-bit A/D converter. 8 channels multiplexer are built in this device, and they are Microprocessor compatible logic levels. This module needs external power supply, of +5V DC @ 300mA.

This is an 8-bit high-speed digital to analog converter module. This module has two independent DAC channels. The output amplitude of digital to analog converter modules is programmable. The output is jumper selected for either unipolar or bipolar mode. In unipolar mode the output is programmable from 0 to +5volts.
In bipolar mode the output is programmable approximately ±2.5volts. The outputs are buffered through amplifiers. A set of 8 LEDs per channel monitor, the data arriving at the input of each DAC. This information is useful to know the output status of DAC.
This is a single channel 8 BIT digital to analog converter module. This module works exactly the same as Dual digital to analog converter module. An external power supply of ±12V @ 250mA and +5V required. We recommend, electronic design experimenter Model EDE-1 for this.
This module is intended to conduct input / output interface experiments. It has 8 SPDT switches connected as input and 8 LEDs as output port. The student learns how to input 8-bit data from an external hardware, and display the same on external 8 -bit LED port. At the time of project design or prototype development, this can be used as a development module, whenever I/O operation is to be performed. It helps in validating the designed program. An external power supply of + 5V @ 250mA is required.
IC 8255 is a programmable input / output peripheral interface. This IC has three numbers of 8 bit I/O ports. By programming, each port can be configured to be an input mode or output mode. This is achieved by connecting this module to a Microprocessor unit, as an input / output. This module makes use of, 8255s used in Microprocessor trainer. This IC can be programmed
in three modes. They are: Basic Input / output (mode 0), strobed I/O (mode - 1), strobed Bi-directional Bus I/O (mode 2). To experiment an 8255 for the above, the trainer is provided with 8 bit Switches, 2 bit independent, de-bounced pulsar outputs, 8 bit tri-state buffer amplifier, 8 bit LED indicator and a built-in power supply. In addition to this, an ergonomically designed front panel with spring activated connecting terminals are provided. With these facilities, this trainer will be self-sufficient. In short using this trainer, all the above modes can be experimented.
