USBMX20 port. Plug the Type A side of the USB cable to the computer’s USB port or to a USB Hub port. Up to four KE-USBMX20 units may be used on the same computer and programmed through the supplied load program.
Page 5: Interfacing To The Ke-Usbmx20 Header
Interfacing to the KE-USBMX20 Header The header on the KE-USBMX20 consists of 9 conﬁgurable pins. The pins are designated as “1” through “9”. Use the supplied KE-USBMX20.EXE program to conﬁgure the header pins as either Rows or Columns. Keystrokes are initiated by shorting a Row pin to a Column pin through a contact closure.
Page 6: Status Feedback Led
Status Feedback LED Status LED The KE-USBMX20 features a status LED on the side for user feedback. When this light is Red, the unit has power but has not been initialized by the system. Once initialized and scanning, the LED will be Blue. When a key is detected as active, the LED will light Green momentarily.
Page 7: The Program Screen
The Program Screen The main program screen displays the conﬁguration settings for the KE-USBMX20. A list of these settings and a description of how they pertain to the KE-USBMX20 setup are listed below. Number of Rows: The number of Rows are selected from the drop down list.
Page 8 Column Pin Assignments: Column pin assignments are selected from the corresponding drop down list across the top of the matrix. Each column must have a header pin assigned to it. Specify any pin “1” through “9” as a column. Row Pin Assignments: Row pin assignments are selected from the corresponding drop down list.

KE- USBMX20. A list of these options along with descriptions of how they pertain to the KE-USBMX20 setup are listed below. When a conﬁguration is created on the screen, it must be written to the KE-USBMX20 to become active on the unit.
Page 10 After the KE-USBMX20 has been loaded with the new conﬁguration, it will scan according to this new setup. ** ** - Note that if multiple KE-USBMX20 units are detected, a selection window will be displayed asking the user to select the unit by it’s serial number.

The keypad matrix layout is shown in the ﬁgure above. Note that the Row and Column signals are intermixed on the keypad. The KE-USBMX20 can be conﬁgured to scan the keypad with it plugged directly into the header with no added wiring.
Page 12 Step 2 After the matrix size has been assigned in step 1, the pins of the KE-USBMX20 header to be used as rows and columns must be deﬁned. On the keypad pins, the row and column assignments from the...
Page 13 Step 3 With the size of the matrix now deﬁned, and the pins selected, assign the keys to be emulated to each position in the matrix. To assign keystrokes, click on the desired matrix position. A diagram of the keyboard will be displayed, as shown below. Click on the representation of the key to assign it to the matrix position.
Page 14 Step 4 The KE-USBMX20 has the capability of sending a macro, or sequence of keystrokes for a single key activation. To program a macro sequence, hold the Ctrl key before clicking on the matrix...
Page 15 When deﬁning a macro, each action is either the press (make) or release (break) of a key. In this example, the desired character for the key is “#”. In order to get this character, it must be entered the same way as it would be manually typed on a keyboard.
Page 16 Macro Example 1: The following macro demonstrates using a macro to send the text “on” when the input is activated and the text “Off” when the input is deactivated. Note also that sending a second make of the “f” key requires that it be issued a “break”...
Page 17 Now that the setup is complete, it can be saved to disk. Specify a ﬁle name under which to save the conﬁguration. Step 6 Load the KE-USBMX20 with the conﬁguration. Be sure that the KE-USBMX20 is connected to the PC. Once the KE-USBMX20 is loaded, it will begin running the new conﬁguration.
Page 18: Ke-Usbmx20 Conﬁ Guration With Fn Key
KE-USBMX20 Conﬁguration with FN key The KE-USBMX20 allows assignment of a key as a “Function” key. This key produces no keystroke itself, but when held down, it alters the keystroke sent by the rest of the matrix. This feature is useful when the keypad has dual legends or needs to respond with different case letters.
Page 19 The keystrokes shown for each key are the keys that will be sent if the FN key is not active when those keys are activated. To deﬁne the alternate keystrokes for each key that will be sent when the FN key is held, put the cursor on the FN cell in the matrix.
Page 20 “A”, “B”, and “C” keys. Now that the conﬁguration has been created, be sure to save it to disk and then Write it into the KE-USBMX20. The following page shows the two matrix conﬁgurations based on the state of the FN key.
Page 21 The above matrix shows the keystrokes sent when keys are pressed and the FN key is not active. (Hold the right mouse button down while left clicking the FN key to toggle between the two matrix tables) The matrix below shows the keystrokes sent in the same matrix when the FN key is held active.
Page 22: Error Messages
“Error while writing to the KE-USBMX20” This indicates that, while the computer can communicate with the KE-USBMX20, it was not able to read or write the conﬁguration. Communication may be interrupted if another program takes the focus away from the KE-USBMX20 application. If this error message is displayed, load the conﬁguration again.
Page 23 “Error saving ﬁle” This error message is shown if the KE-USBMX20.EXE program attempts to save a ﬁle that is already open in another application, or if there is not enough disk space. If this happens, close the other application and try saving the ﬁle again.
Page 24: Ke-Usbmx20 Operating Tips
This arrangement allows for scanning of most keypads up to a 20 key matrix. When using less than the full 9 pins on the KE-USBMX20, insert the included keying plug to help with the header alignment. • When using a macro sequence, a break or release of a key must be made for any make or press of the key that was done earlier in the macro.
