LT-4 Data Terminal • Timm Elektronik

Benefits

Easy handling even with working gloves
Illuminated display
The integrated device heating is thermostated and eliminates the usually adverse behavior of LCD displays at very low ambient temperatures
Universal interface for flexible joint connectivity of multiple terminals and card readers via one KCS system

Allows the build-up of access control and identification systems at entry and exit areas
For input, display and processing of data
Used in e.g. refineries, tank farms, chemical industry, pharmaceutical industry, food industry or power plants
Universally usable as a supplement to the card reader system or as a standalone system with data interface and slave card reader

30 definable large keys with insertable labeling strips
Design of the LC display as an alphanumeric display (4 lines x 20 characters, character height 8 mm) or as graphic display (120 x 32 Pixel)
Display messages are transmitted by the host computer or provided by pre-programmed masks
The operation as a “bus-slave“ (RS485 bus) with the customer-specific AMCC protocol is possible via the universal interface
For direct point-to-point communication with higher-level computers, the universal interface can also be configured as a RS422 or TTY interface e.g. using the transmission protocol DUST3964R (Siemens)
