Keypad Data
The keypad sends a 26-bit data stream when a proper PIN number (1-65,534) is entered;
followed by the # key, see Table 1. The PIN number will appear as a binary number in the
X field. The A field is 000, however, custom site code PINpads are available on request.
All data is transmitted first as Most Significant Bit (MSB).

The keypad will transmit 16 “ones” in the X Field (Bits 10-25) when any of the following
occurs:
•
The # key is pressed with no preceding data
•
Any number of zeros followed by the # key
•
Any number greater than 65,534 is pressed prior to the # key
The equipment to which the keypad is attached should be configured to recognize 16
“ones” in the X field (X=65,535) as an incorrect “Error” code.
