CD-11 Indicators are equipped with a standard IBM TM
compatible, bi-directional RS232 interface for communi-
cation with printers and computers. When the Indicator is
connected directly to a printer or Programmable Logic
Controller (PLC), displayed data can be recorded at any
time by simply pressing the PRINT/UNITS button.
Connecting the Indicator to a computer or PLC enables
you to operate several functions of the Indicator from the
computer, as well as receive data such as displayed
weight, weighing mode, stability status, etc.
