3.3.3 P702 Board to Board Connector
This connector is an alternative interconnection method to P301 and P701.
Table 4: P702 Pin Configuration
1 nHold Input
Signal that holds off the presentation of the
card data. When asserted, this line either
buffers a card or disables a card read until
released, as configured (active low).
2 VIN Supply Supply Voltage Positive
3 DNC Do Not Connect
4 VIN Supply Supply Voltage Positive
5 NC
6 VRTN Supply Supply Voltage Negative
7 URX Input UART data in
8 SPI_MISO Output SPI data out
9 UTX Output UART data out
10 SPI_MOSI Input SPI data in
11 WG_DATA1 Output Wiegand Data 1
12 VRTN Supply Supply Voltage Negative
13 WG_DATA0 Output Wiegand Data 0
14 DNC Do Not Connect
15 DNC Do Not Connect
16 DNC Do Not Connect
17 DNC Do Not Connect
18 nReset Input Reset (active low)
19 +3.3VDC Output 0.1W maximum power sourced output
20 VRTN Supply Supply Voltage Negative
21 nGLED_CPRES Output
The signal on this pin reflects the recognition
of a card near the antenna. The autonomous
read and buffered data from the credential is
output on the configured host interface.
22 SPI_CLK Input SPI clock signal
23 nBeeper Output Signal which enables off board signaling
24 SPI_nCS Input SPI chip select (active low)
25 NC Not Connected
26 VRTN Supply Supply Voltage Negative
27 DNC Do Not Connect
28 nRLED Output Use this signal to enable an off board LED
29 DNC Do Not Connect
30 NC Not Connected
