Signals
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
Symbol Synapse host. Pin is shorted to RTS/SYN_DAT in USB
cables to allow auto-detection of USB mode via signal loopback.
Power supply ground input and signal ground reference.
5.0 VDC ± 10%
I/O
RS-232 Mode: Clear-to-send handshaking input line, used only in
conjunction with the RTS line. Optionally used by another device to
signal the scanner to begin transmitting data.
USB Mode: D- signal. During USB operation this signal works in
conjunction with the D+ signal as a differential bi-directional signal.
Function
to begin scanning session.
