Wiring Instructions 
14 AY-G/H6xx0 Installation and User Manual 
• The individual wires from the reader are color coded according the 
Wiegand standard. 
• When using a separate power supply for the reader, this supply and 
that of the controller must have a common ground. 
• The reader’s cable shield wire should be preferably attached to an 
earth ground, or a signal ground connection at the panel, or power 
supply end of the cable. This configuration is best for shielding the 
reader cable from external interference. 
To connect a terminal block reader to the controller: 
1. Prepare the controller cable by cutting its jacket back 5 cm (2") 
and strip the insulation from the wires 1.3 cm (½"). 
2. Connect the controller cable to the terminals (see Table 1). 

Reader Operation 
AY-G/H6xx0 Installation and User Manual 15 
5. Reader Operation 
Once the reader is wired to a power supply and to the controller, you 
should test the reader. 
To test the reader: 
1. Power up the reader. 
The beeper sounds three times and the LED turns red, blue, and 
green, to indicate that the reader is working properly. The LED 
returns to its Standby mode (red for the AY-x6x70 series and blue 
for the AY-x6x80 series). 
2. Present the appropriate type of proximity card to the reader or 
enter a valid keypad entry. 
The reader emits a beep (0.5 seconds). The LED changes 
momentarily to green and then returns to its Standby mode (red 
for the AY-x6x70 series and blue for the AY-x6x80 series). 
The reader transmits the card's data or the keypad entry to the 
controller for validation. 

Proximity Operation 
16 AY-G/H6xx0 Installation and User Manual 
6. Proximity Operation 
6.1 Supported Credential Technologies 
O2S readers support reading from the secure memory of the 
following credential technologies: 
 AY-H6x80 and AY-G6x80 
 MIFARE DESFire EV1 (2K, 4K, 8K) 
 MIFARE Classic (1K, 4K) 
 AY-H6x70 and AY-G6x70 
 MIFARE Plus X (2K, 4K) 
 MIFARE Plus S (2K, 4K) 
 MIFARE Classic (1K, 4K) 
6.2 Wiegand Output 
For O2S credentials, the reader outputs the ID data stored in the 
secure memory (sector/file) of the credential. The ID data defines the 
output as Wiegand and also determines the bit length of the output. 
For example, when reading an O2S 26A format credential, the reader 
outputs a Wiegand 26-Bit ID. 
For non-O2S credentials, the reader outputs the CSN of the credential 
as a Wiegand 32-Bit ID.

AY-G/H6xx0 Installation and User Manual 21 
7.5.4 Option 4: 4 Keys Binary + Facility Code, 
Wiegand 26-Bit 
This option buffers 4 keys and outputs keypad data with a 3-digit 
Facility code like a standard 26-bit card output. 
The Facility code is set in Programming Menu 4 and can be in the 
range 000 to 255. The factory default setting for the Facility code is 
000 (see Section  7.7 for more information). 
The keypad PIN code is 4 digits in length and can range between 
0000 and 9999. On the fourth key press of the 4-digit PIN code, the 
data is sent across the Wiegand Data lines as binary data in the same 
format as a 26-bit card. 
If * or # are pressed during PIN code entry, the keypad clears the PIN 
code entry buffer, generates a beep, and is ready to receive a new 4-
digit keypad PIN code. 
If the entry of the 4-digit keypad PIN code is disrupted and no number 
key is pressed within 5 seconds, the keypad clears the PIN code entry 
buffer, generates a beep, and is ready to receive a new 4-digit keypad 
PIN code: 
(EP) FFFF FFFF AAAA AAAA AAAA AAAA (OP) 
Where: 
EP = Even parity for first 12 bits 
OP = Odd parity for last 12 bits 
F = 8-Bit Facility code 
A = 16-Bit code generated from keyboard 
7.5.5 Option 5: 1 to 5 Keys + Facility Code, Wiegand 
26-Bit 
Option 5 buffers up to 5 keys and outputs keypad data with a Facility 
code like a 26-bit card output. 
The Facility code is set in Programming Menu 4 and can be in the 
range 000 to 255. The factory default setting for the Facility code is 
000 (see Section  7.7 for more information). The keypad PIN code can 
be one to five digits in length and can range between 1 and 65,535. 

Keypad Operation Instructions 
22 AY-G/H6xx0 Installation and User Manual 
When entering a keypad PIN code that is less than 5 digits in length, # 
must be pressed to signify the end of PIN code entry. For keypad PIN 
codes that are 5 digits in length, on the fifth key press of the 5-digit 
PIN code, the data is sent across the Wiegand Data lines as binary 
data in the same format as a 26-bit card. 
If * is pressed during PIN code entry or a PIN code greater than 
65,535 is entered, the keypad clears the PIN code entry buffer, 
generates a beep and is ready to receive a new 5-digit keypad PIN 
code. 
If the entry of the 1- to 5-digit keypad PIN code is disrupted and a 
number key or # is not pressed within 5 seconds, the keypad clears 
the PIN code entry buffer, generates a medium length beep, and is 
ready to receive a new 1- to 5-digit keypad PIN code: 
(EP) FFFF FFFF AAAA AAAA AAAA AAAA (OP) 
Where: 
EP = Even parity for first 12 bits

A = The first key entered D = Fourth key entered 
B = Second key entered E = Fifth key entered 
C = Third key entered F = Sixth key entered 
7.5.7 Option 8: 1 to 8 Keys BCD, Clock & Data 
Option 8 buffers up to 8 keys and outputs keypad data without a 
Facility code like standard Clock and Data card output. 
The keypad PIN code can be one to eight digits in length. The PIN 
code length is selected while programming the reader for Option 8. 
The reader transmits the data when it receives the last key press of 
the PIN code. The data is sent across the two data output lines as 
binary data in Clock & Data format. 
If * or # is pressed during PIN code entry, the keypad clears the PIN 
code entry buffer, generates a beep, and is ready to receive a new 
keypad PIN code. 
If the entry of the keypad PIN code is disrupted and a number key or 
# is not pressed within 5 seconds, the keypad clears the PIN code 
entry buffer, generates a medium length beep, and is ready to receive 
a new keypad PIN code.

OSDP Operation 
AY-G/H6xx0 Installation and User Manual 27 
8. OSDP Operation 
Rosslare O2S readers that support OSDP operation are compatible 
with most OSDP commands. The reader address is set using DIP 
switches on the back of the reader. 
The DIP switch settings are as follows: 
DIP Switch 1 
This switch is used to select the reader output (Wiegand or OSDP): 
 Off = Wiegand 
 On = OSDP 
DIP Switch 2 
This switch is used to determine what cards are read: 
 Off = O2S cards and CSN of non-O2S cards 
 On = O2S only 
DIP Switch 3 
This switch is reserved for future use. 
DIP Switches 4 to 8 
These switches set the address of the reader for OSDP protocol. 
DIP Switch 4 is MSB and DIP Switch 8 is LSB. The address is the DIP 
switch state +1. 
Examples: 
 All the DIP switches in Off position, state is = 0 => address = 1 
 All the DIP switches in On position, state is = 0x1F => address = 
0x20 = 32 
 DIP switches 4, 6, 8 in On position and 5, 7 in Off position, state 
is = 0x15 => address = 0x16 = 22
