The DACIO 300 series modules are powerful, ultra low power consumption, microcontroller (MCU) based PC interfacing RS232 Input Output boards with digital IO and analog inputs.

A single RS232 IO board provides two 8-bit digital input/output ports and up to 8 analogue input channels to computers equipped with a spare RS232 COM port or via a USB to serial converter such as item 2455 or 2327.

Each I/O is individually configurable.
Tried and tested, ultra reliable, easy to use communication and control open protocol.

The DACIO 300 features 8 10-bit A/D and a high speed 115.2kbps serial interface.

UK manufactured and tested & Lead free / RoHS compliant.

Ultra reliable, commercial strength open ASCII protocol.

Industrial strength ESD protection on high speed RS232 interface.

or use a USB to serial converter.

Note that the DACIO MPU is available separately and when powered at 3.3V is directly compatible with the 3.3V logic from a Raspberry Pi.

Free software and terminal program

The advanced design features unmatched power and ease of use at a
budget price. These PC interfacing RS232 IO boards are useful for applications
requiring a serial to parallel (and parallel to serial) converter.

It is ideal for use in computer controlled systems, for digital/analogue data
acquisition, robotics, automatic testing equipment, process control or
for experimental and educational purposes.

This RS232 IO card features industry standard RS232 line drivers.
Baud: 9600 and 115200 bps - others available on request.

Flexible and easy to remember bit, byte or 16-bit instructions.
Full (but suppressible) error reporting. Two status LEDs.

Quickstart guide, default settings, LED demo and powerful trace
feature gets you up and running in minutes! Intelligent on-board micro
communicates with a Terminal program on the host computer
allowing you to run demos or try out all the features by typing
commands manually.

Simple module configuration.
