The factory default Wiegand data transmission setting for the keypad portion of the PROX-2 is 8-bit burst, though it is capable of
transmitting data in the 26-Bit Wiegand mode. The keypad uses the Wiegand Keypad Data Mode control card, presented to the read-
er, to change between the 8-bit burst and 26-bit Wiegand data modes.
Note: The PROX-2 keypad does not support magnetic stripe output.
Note 1: Read range is stated in a clean RF and electrical environment using Viking Proxcards presented parallel to the
reader surface with the reader operating at 12 VDC. Additionally, read range may be affected by local installation condi-
tions. Range will be less when mounting to metal.
Note 2: For user orientation in non-illuminated environments the 5-key is always illuminated.

• 8-Bit Burst (factory default setting)
• 26-Bit Wiegand
A. Keypad Output Formats
The proximity reader and keypad portions of the PROX-2 both share the Wiegand data lines. Specifically keypad data is transmitted in
either an 8-Bit Burst (default) or 26-Bit Wiegand data format.
• For user orientation in non-illuminated environments the 5-key is always
illuminated.
• Card presentation or a key press illuminates the keypad for approximately
20 seconds. Further, each key press generates a single beep and LED
flash from the PROX-2.
• The non-mechanical capacitive technology utilized by the PROX-2 is
optimized for use with a bare finger.
• For best operation when entering a PIN it is recommended that the user’s
finger be physically lifted from the keypad between key depressions.
Only one key can be pressed at a time.
Note: If powering the reader from its own
power supply, the negative lead of the power
supply must be connected to the BLACK lead
on both the reader and the controller.
