I Signals to scanner to begin scanning session.
O Serial data transmit output. Drives the serial data receive input on the
device communicating with the scanner.
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.
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.
Power supply ground input and signal ground reference.
