DIAGNOSTICS TERMINAL

The Diagnostic Display Terminal is a robust terminal device constructed for harsh environments. A special wide temperature electronic, a wide temperature LCD (4×40 characters, LED backlight) and a switch panel with EMI protection are used to meet the EN50155 and the IEC 801-x specifications. The device is resistant to shock and vibration and well-protected against dust and water (front panel: IP65). Encased in a robust aluminum box and without the need of a cooling fan, the Diagnostic Display Terminal can operate from -20°C to +70°C at relative humidity of 95%.

The communication between Host and Diagnostic Display Terminal is realized by a serial link: either RS422 (standard), or RS485. The I/O-signals for RS422 and RS485 are electrically isolated.

The Diagnostic Display Terminal itself generates scan codes which are sent to the Host every time a key is pressed or released (MAKE and BRAKE-codes).
