The CTM200 series terminals are compact, rugged, industrial data entry and display terminals. They are intended for use as operator panels and as service/setup panels in microprocessor based equipment. The CTM200 terminals have three families from which to choose: the CTM200, basic terminal models, the CTM250, advanced terminal modes with LCD display, and the CTM280, advanced terminal models with LED display.

The CTM200 series of terminals is available in the following models:

  • CTM200 – LCD terminal with RS-232
  • CTM250 – LCD terminal with RS-232, auxiliary port
  • CTM280 – LED terminal with RS-232, auxiliary port

CTM200 and CTM250 Base Features

  • A large 16 character Liquid Crystal Display
  • The sealed keyboard has 24 keys. By using the SHIFT key, the six function keys are mapped to give access to 18 functions.
  • A signal for an external beeper
  • Runs on standard +5 VDC

CTM250 Extended Features

  • An auxiliary digital I/O port that can be configured as one of the following:
    • Digital I/O with 8 TTL inputs and 8 TTL outputs
    • Parallel Printer Port
    • Serial Port
  • An internal beeper
  • Backlight (LEDs), for function keys
  • Voltage regulator to handle +7.5 to +12 VDC power input

CTM280 Extended Features

The CTM280 terminals are identical to the CTM250 terminals with the following exceptions:
  • 1×16 LED display
  • Adjustable brightness levels (5 levels)
  • Extended temperature operation
  • Power requirement up to 400mA, depending on display brightness
  • 7.5 to 12 VDC supply voltage range
