Functional Description
The master terminals of the series IF 152x are part of a time and attendance recording system. They
are installed close to where employees work and connected directly to the higher-ranking system, e.g.
to a PC or a router by means of a data line. These master terminals have been designed to record
time data such as work time begin, work time end, cost center data as well as change of cost center.
For entering data, these master terminals are equipped with a magnet swipe card reader, a numeric
keypad, soft keys, special keys - Clear, Enter, Right, Left -, Depending on the host program and the
parameter settings, different functions can be assigned to the soft keys, e.g. IN, OUT, DISPLAY,
ABSENCE REASONS or COST CENTRES.
A 4 x 20-digit back lighted alphanumeric LCD display guides the operator and shows the current time.
All card bookings and events are recorded in the internal RAM and transferred to the higher-ranking
system. Depending on the preset conditions in the access/ time program, a booking is either rejected
or accepted and the decision is shown on the display.
