What does a Keyboard Encoder
do?
Our Keyboard Encoders convert input from devices
such as keypads or switches into PC keyboard signals. The Encoder
looks exactly like a keyboard to your PC. Pressing a button on
a keypad connected to the keyboard encoder or activating a switch
you have connected to the encoder will produce a keystroke on
the PC just as if it were coming from a keyboard. Your PC will
also boot without your keyboard attached, since the encoder supplies
all the required communication to the PC.
Why use a Keyboard Encoder?
Many PC applications rely on input from the keyboard
to perform certain actions or execute commands. The keyboard
encoder
allows the user to send these commands from his own device, such
as a pushbutton switch, instead of pressing a key on the keyboard.
In addition, many PC programs do not require the use of a full
keyboard. Use of a Keyboard Encoder allows restriction of the
keys available to operators by using another input device. You
may interface your own keypad or switches to emulate any of
the
standard keys from your PC keyboard. The encoders can be used
with a keypad that is more suitable to environmental conditions
than a standard PC keyboard.
Can I still use my own keyboard?
Our Keyboard Encoder products feature a port to
connect your standard PC keyboard. You may use your own keyboard,
although it is not required for the Encoder operation. The Keyboard
Encoder will supply all necessary communication to your PC on
power up.
What types of computers do the
Encoders work with?
Use our Keyboard Encoders with PC AT, XT, PS2,
Pentium, and compatible computers. We offer versions with either
5 pin
DIN or 6 pin miniDIN connectors. We also have USB products as
well, which interface to your USB port.
Do I need to supply power to
the Encoder?
Keyboard Encoders used with a PC do not require
an additional power supply. Our Encoders use the power from
your
PC keyboard Port.
Do you have RS-232 interfaces?
The Hagstrom Electronics KE24 Keyboard Encoder
supports RS-232 communication. This product is programmable
and the RS-232
port may be used in a number of ways. Data received on this port
may be translated into PC keyboard signals; Keystrokes from
a
PC keyboard may be directed out to this port instead of the PC;
Keypads or Switches scanned on the I/O header may have their
responses
sent to the RS-232 port. Our KE72 unit also features an RS-232
port which will receive ASCII characters and convert them into
keystrokes.
What is the product Warranty?
Our Keyboard Encoders are backed by a ONE year
warranty against defects in material or workmanship.
