MS240/241 Manual
MS240-3
The MS240-3 AT keyboard wedge interface has a “Y” interface cable
with an AT male plug on one end and an AT female plug on the
other. The cable end with the male plug is inserted into your
computer’s keyboard port and your keyboard is plugged into the
female plug.
The MS240-3 operation should be “plug and play”. The MS240-3
has a built-in decoder that outputs the scanned data in Scancode
keyboard format. Your computer will treat your MS240-3’s input as
it would normal keyboard input.
Note: If you are using a laptop computer or a USB keyboard (ie.
you are not using an AT keyboard), then your MS240-3 will need to
be configured as a “Keyboardless Wedge” (see “Device” in the
“Scanner Configuration Manager” section.

MS240-2
The RS232 (Com Port) interface should only be used when your
software is designed to accept com port input. The MS240-2 has a
built-in decoder and outputs the scanned data in ASCII Code.
MS240-2 input requires special software such as HyperTerminal
(9600 bits per second, 8 data bits, No parity, 1 stop bit, No flow
control) in order to view the output.
Note: The MS240-2 will require an optional 5V 300mA power
supply unless your computer’s com port supplies power (unlikely).
MS240A
The Undecoded (or TTL, or Wand) MS240A requires an external
decoder in order to communicate with your computer. Decoders are
built into Wedge devices and many POS (Point of Sale) keyboards,
such as the Unitech KP3700.
The MS240A cannot be configured via Scanner Configuration
Manager. Any modification of the output data must be done in the
external decoder.
Following are the the various model numbers / interfaces available
for the MS240/241 and the specifics of each.
