KE-USBMX20 Operating Tips

Please check the following items before contacting us.

• When connecting the KE-USBMX20 to a PC use a standard

USB A- micro B type Cable. Maximum length 15 ft.

• Check the KE-USBMX20 conﬁguration. Check the matrix

conﬁguration for the number of Columns, Rows, etc. Review

the matrix table for the desired responses.

• If the keypad attached to the header has a connecting cable

(such as with a membrane switch) be sure it is no more than

10 feet in length.

• The KE-USBMX20 scans a matrix size in any combination

of the pins from 1 x 8, to 4 x 5. 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.

• The KE-USBMX20 sends keystrokes. To get a speciﬁc

character, a macro may need to be created to emulate the

same sequence normally used to manually type the character.

For example, “$” is a shifted “4” key on the USA keyboard. The

macro for “$” would make (press) the Shift, then make the
“4” key, then break (release) both keys.

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.

The pins that are deﬁned as Columns will sink current while

scanning the matrix. The Rows are used to read the status of

the inputs when a Column is active.

Keypads with male headers can be directly plugged onto the KE-

USBMX20 connector. KE-USBMX20 pins can be conﬁgured to

be either Rows or Columns to allow for this direct attachment.

*Note:

Keypads with male pins may be connected directly. For

membrane keypads with female headers, adapters may be used

to directly connect from the pigtail to the KE-USBMX20 header.

(See Accessories on page 20)
