A unique feature of the LK162-12/VK162-12
is the ability to control relays*
and other external devices
using either one or
seven
General Purpose Outputs.
Each can source up to 10mA of current at five
volts
when on or sink 20mA at zero volts when off.
In keypad input mode,
a matrix style keypad of up to twelve keys
to be directly connected to the display
module.
Key presses are generated when a short is detected between a row and a column.
When a key
press is generated, a character
specific to that key press
is automatically sent on the Tx communication
line.
If the display module is running in I2C mode, the “Auto Transmit Keypress” function may be turned
off
to allow the key presses to remain in the
buffer so that they may be polled.
The character that is
associated with each key press may also be altered using the “Assign Key Codes” command.
The straight fourteen
pin header of the General Purpose Input/Output connector
will interface to a
variety
of different devices including the
Matrix Orbital KPP4x4 keypad.
*Note:
If connecting a relay, be sure that it is fully clamped using a diode and capacitor in order to absorb any
electro-motive force (EMF) which will be generated.

In addition to the six general purpose outputs the LK162-12/VK162-12
offers an Optional Dallas One-
Wire bridge, to allow for an additional thirty two one-wire devices to be connected to the display. This
header can be
populated with a Tyco 173979 connector at an added cost by custom order only.
