Function
1
Trigger
I
Signals to scanner to begin scanning session.
2
TXD
O
Serial data transmit output. Drives the serial data receive input on the 
device communicating with the scanner.
3
RXD/D+
I/O
RS-232 Mode: Serial data receive input. Driven by the serial data 
transmit output on the device communicating with the scanner.
USB Mode: D+ signal. During USB operation this signal is pulled up by 
a 1.5k Ohm resistor to begin USB enumeration. In this mode it is a 
differential bi-directional signal.
4
 SYN_CLK
I/O
Synapse Mode: Synapse Clock line. Signal used as a clock by a 
Synapse host. Pin is shorted to RTS/SYN_DAT in USB cables to allow 
for auto-detection of USB mode via signal loopback.
5
Ground
Power supply ground input and signal ground reference.
