ILM-216L Two-line by 16-character Serial LCDs
ILM-216s are supertwist LCDs with an advanced serial interface integrated into the LCD controller board. The LCD displays text received serially, and the interface understands common terminal-style formatting instructions (e.g., carriage return, tab, etc.) In addition, the ILM-216L has four switch inputs that can be polled through the serial interface.
ILM-216 Features
- Terminal-style control codes for easy programming
- 1200-9600bps serial input with 16-byte buffer
- Instruction-controlled LED backlight
- Automatic right-alignment feature for spreadsheet-perfect formatting
- EEPROM storage of configuration settings, custom startup screen
- Deep inventory for no-lead-time delivery

LCD Instructions
The ILM-216 works like a mini-terminal, displaying text and responding to traditional control characters like linefeeds, carriage returns, tabs, etc. The ILM also provides four switch inputs that can be polled serially and EEPROM storage of configuration options and a startup screen.
