POWER SUPPLY – TTL
The TTL interface is a surface-mounted, dual-row, 6 circuit
connector (Molex Microfit connector) with a press-fit metal
retention clip.

POWER SUPPLY – MDB
The MDB ICP is a standard interface for communicating with
the vending machine controller (VMC). The VMC is integrated
into the vending machine and controls various peripherals.

PROXIMITY SENSOR
The VALINA is fitted with a proximity sensor that helps supports
smart energy consumption by switching between different states.
Power consumption
State Details
Transaction Terminal processing transaction by Ethernet (backlight on)
Sleep
Wake-up triggered by proximity detector wake-up time
≤ 1 second
Stand-by
Wake-up triggered through TTL port wake-up time
≤ 65 seconds
POWER MANAGEMENT
VALINA is equipped with smart power management profiles.
Each profile puts the terminal in a different state and supports
different ways to wake up the terminal. Using the different
profiles in a smart way will minimise the amount of energy the
VALINA requires when not in use for a transaction. The infor-
mation below is indicative. Measurements in the field may dif-
fer, depending on applications that might call for additional
resources.
Stand-by profile
Consumption:
• 0.019 W
Wake-up possibilities:
• external trigger via the TTL I/O interface
• reset button on the back (not accessible by cardholder)
• double pulse via the TTL I/O interface

Wake up time:
65 seconds to make the terminal available in a ready for trans-
action state
Sleep profile
Consumption:
• 0.104 W
Wake-up possibilities:
• alarm generated by the Real Time Clock (RTC)
• insertion of a card
• proximity sensor detecting someone approaching the machine
• input on TTL I/O (same as stand-by mode)
• Reset button on the back (not accessible by cardholder)
• data on the serial interface (RS232)
Wake up time:
1 second to make the terminal available in “ready” state
Transaction profile
Consumption: 2.4 W during the transaction
