perform the following functions:
• Data Collection – the DT220 collects data from the A/D, serial communication ports,
TTL inputs, and the full alpha/numeric keyboard.
• Database Management – up to 6 data tables are available for organizing, storing and
reporting data.

functions, TTL level 'setpoint' inputs and outputs, and remote control via TTL inputs
or RS232 serial input.
The DT220 has the following interfaces:
Three bi-directional serial communication ports that are used for printer output, bar code
input, computer communications, and remote control applications. The serial ports
support RS232, RS422, RS485, and 20ma Current Loop communication.
