Using the M5100 Keyboard Wedge
The M5100 Keyboard Wedge is an optional accessory of the M5000 Portable Data Terminal. It
interfaces between a standard IBM compatible keyboard and your personal computer. The M5100
Keyboard Wedge transmits data to the
computer as if it were typed from the
keyboard.
The advantage of using a keyboard wedge
is that software is not needed for
connectivity. The M5100 Keyboard Wedge
interface connects between the keyboard
and the PC with a Y-cable. The M5000 PDT
connects to the wedge to upload data. The
computer remains fully functional while
data is transmitted via the keyboard directly
into your computer’s application. In
addition, the M5100 Keyboard Wedge has
the ability to convert standard RS-232 data
into keyboard data.
M5100 Wedge Programmer Software is
included with the purchase of the M5100
Keyboard Wedge. This application allows
for modification of keyboard wedge settings
such as transmit speed, keyboard type and
RS-232 conversion settings. In most cases, the manufacturer default settings programmed into the
M5100 Keyboard Wedge are acceptable and changes to the wedge programmer settings are not
necessary.
How to connect the M5100 Keyboard Wedge to your computer:
1. Turn off the power to your computer.
Warning!
Failure to terminate the power can permanently damage the system.
2. Unplug the keyboard connector from the back of your computer and plug it into the female end
of the Y-cable.
3. Plug the male end of the Y-cable into your keyboard port.
4. Connect the wedge to the 9-pin connector on the Y-cable.
5. Connect the interface cable to the 9-pin male connector on the wedge.
6. Connect the RJ45 10-pin connector end (resembles a telephone jack) of the interface cable to the
bottom of the M5000 PDT.
7. Turn on the power to your computer. In keyboard wedge mode, power to the M5000 PDT is
automatically received from the PC.
Using the M5100 Wedge Programmer
When the keyboard wedge cable is connected, the M5000 PDT switches to the keyboard wedge
mode automatically. During keyboard wedge mode the M5000 PDT receives all its power from the
keyboard port and does not use its internal battery. The M5000 PDT turns on and off with the host
computer.
The M5000 Utilities automatically includes the M5000 Programmer, M5100 Wedge Programmer,
and Softcom. You may run these programs by selecting the appropriate icon.
Follow these steps to initiate the M5100 Wedge Programmer software:
